following is the pertinent failure Quick and problem-solving power
Brain malfunction causes confusing, puzzling. And because the Windows operating system components is relatively complex, computer event of a failure, for the average user, you want to accurately identify the fault
Reason is almost impossible. So it is that if we experience computer failure, completely helpless out? This is not so, the computer-generated although there are many reasons for failure, but as long as we carefully
Observation, conscientiously sum up, we can still have some computer failures of the law and approach. In this booklet, we will some of the most common and most typical computer fault diagnosis, maintenance means show
To you, through it, you will find - ways to solve computer failure on your side, simple, but effective!
a motherboard
motherboard is the computer off
Key components in the computer plays a vital role. If the board will have problems affect the whole PC computer system work. Here, we take a look at the motherboard in the course of which the most common faults.
often
See Fault 1: no display
boot the computer boot no display, we need to check is the BIOS. Motherboard BIOS the hardware store important data, while the main BIOS is
Board some of the more brittle, easily damaged, once damaged it will cause the system can not run, the recurrence of such failures are generally due to the motherboard BIOS damage caused by CIH virus (of course not rule out the motherboard itself failed
Cause the system can not run. ). General BIOS hard drive after the virus broke data will be lost, so we can detect the hard disk data is intact to determine whether the BIOS is damaged, if the hard disk data
Intact, then there are three reasons why the phenomenon of power no display:
1. Because the motherboard or expansion card expansion slot problems, leading to plug expansion cards like sound cards, etc. without the display after the board did not respond.
2. motherboard jumper settings in the CMOS the CPU frequency does not, may also lead to not show fault, which, as long cleared CMOS to be addressed. Clear CMOS jumper on the motherboard of the battery with the general
Recently, in its default location is 1,2 short, at the peak of the change of its short jump for a few seconds to 2,3 to solve the problem, should the old board for the previous user can not find the jumper, equitable remove the battery, to be displayed to enter the boot
CMOS settings and then shut down, will go up also reached the CMOS battery on dismiss purposes.
3. motherboard does not recognize the memory, memory corruption or memory does not match the boot no display can lead to failure. Some older motherboards more selective memory, once the plug in the motherboard does not recognize the memory, the motherboard will not start, and even some
Board does not give you any fault tips (tweet). Of course sometimes in order to expand the memory to improve system performance, plug in the results of different brands, types of memory will also result in the emergence of such a failure, so maintenance should be
Pay more attention.
for the failure of the motherboard BIOS is damaged, we can plug in the ISA card to see whether the display (if prompted, can prompt steps below.), if only
A boot screen, you can own an automatic update the BIOS floppy disk, reload the BIOS, but some motherboard BIOS is damaged, the floppy drive did not work this time, try to solve with the hot method
Decision (I have tried, by the time the same BIOS, the motherboard at the same level can be successful writer.) However, in addition to the use of hot entities, need the same BIOS part of the motherboard components can cause damage, so reliable
The device is used to write code to write the BIOS update file inside the BIOS (this service can be to find a safer computer business solutions).
two common faults: CMOS settings can not be saved
Such failures are generally due to the motherboard battery voltage is insufficient cause, which can be replaced, but some motherboard battery is replaced, the same can not solve the problem, then there are two possibilities:
1. Motherboard circuit problems This professional service to find;
2. motherboard CMOS jumper problem, sometimes because of the error will clear the CMOS jumper set to clear the option, or set to an external battery, making the CMOS data can not Save.
Troubleshooting
III: In Windows, install the motherboard driver CD-ROM drive after crash or cut corners the phenomenon
in some no-name motherboard sometimes these phenomena occur, the motherboard drivers installed
Finished, restart the computer can not enter the Windows 98 desktop in normal mode, and the driver under Windows 98 can not be uninstalled. If this occurs, it is recommended to re-find the latest drivers installed, the problem usually can be resolved, if it is not, only to re-install the system.
Troubleshooting
Four: Installing Windows, or start Windows when the mouse is not available
recurrence of such failures because the software is generally caused due to the CMOS settings wrong. In the CMOS settings
Power management has a modem use IRQ field project, his options are 3,4,5 ......, NA, generally it is the default option is 3, set it to 3 other items that interrupt available.
Common Fault 5: Frequent computer
Crashes, during the CMOS settings will crash phenomenon
crash phenomenon occurs in CMOS, usually the motherboard or CPU problem, should the reception statute can not solve the problem, it only
Have to replace the motherboard or CPU.
recurrence of such failures are generally due to a problem or motherboard motherboard Cache heat caused by bad design, I had found on the 815EP motherboard because the motherboard
Heat is not good enough cause the failure of the phenomenon. In touch after the crash motherboard components around the CPU, found that the temperature is very hot. After replacing the high-power fans, crash failures can be resolved. For Cache problem
Failure, we can enter the CMOS install, the Cache can fix the problem after the ban, of course, Cache disability, the speed would surely be affected.
Common Fault 6: Motherboard
COM port or collateral port, IDE interface failure
recurrence of such failures are generally due to causes related hardware hot plug the user, the user is able to use multi-function card to replace, but must be in place before
Prohibit the motherboard comes with a COM port on the parallel port (some motherboards with the IDE port to be banned for appropriate use).
graphics
common faults one: boot no display
such it
Barrier is generally bad because the graphics card or motherboard with the motherboard slot caused a problem. Fjust aboutme integrated graphics motherboard, chief memory whether the shared memory, you need to disburse attention to memory position, routinely in the first memory slot should be
Inserted in the memory. As the card causes boot no display failure, power is generally given after a long 2 short beeps (in terms of graphics for AWARD BIOS).
Troubleshooting II:
Show the video, writing
not see such failures are generally due to high-resolution monitor or video card does not support caused. Huaping startup mode can be switched to secure mode, then in
Windows 98 into the display settings, the 16-color mode click on the Restart in normal mode Windows 98 system, delete the graphics drivers, restart the computer. Or not to enter secure mode, in a pure DOS environment, edit
SYSTEM.INI document,
display.drv = pnpdrver to display.drv = vga.drv afterward retention and exit, and then in Windows Update
driver.
often
See Failure three: color display is not normal, such failures are generally the following reasons:
1. Display card and monitor signal line bad
2. Display their failure
3. Some software running in color is not normal, usually common in older machines, there is a check in the BIOS, the color option to open it to
4. Graphics damage;
5. display is magnetized, generally due to such phenomena with magnetic objects can be caused by too close after magnetization may also cause screen appears deflection phenomenon.
Fault IV: Death
Recurrence of such failures are generally more common in motherboards and graphics cards are not compatible with the graphics card or motherboard is bad; graphics card is not compatible with other extensions can also cause crashes.
Common Fault 5: Screen eccentric rumpus
Or pattern
such failures are generally due to problems with memory or graphics cards caused by poor contact with the motherboard. Need to clean or replace the card trick site was
card.
often
See Fault 6: graphics card driver is lacking
graphics driver to load and scamper automatically after a time of driver loss, such failures are generally due to poor quality or graphics card not compatible with the motherboard
Capacity, production the graphics card temperature is too high, causing the system unstable or crash, then only replace the video card.
In addition, there is a special kind of situation before to load the graphics driver, but
In the graphics driver fraught into Windows when the crash occurred. Can replace other types of cards, after loading the driver, insert the old card to be addressed. Should such a failure can not be resolved, then the Note
Book table failed, to restore the registry or reinstall the operating system can be.
Troubleshooting a sound card: sound dumb. There are common causes of this failure:
1. Driver default output to Click the bottom right edge of the sound icon (a small loudspeaker), appear to adjust the volume slider, under the Normal pronunciation.
2. sound card conflict with other cards. The solution is to adjust the PnP cards used by system resources, so that always cards without afflicting each other. Sometimes, open the Is not sound, in fact, there is conflict, but the system did not check out.
3. After installing the Direct X sound card can not be audible. Illustrate this sound card with Direct X compatibility is not good, need to update the driver.
4. one channel silent. Check the sound card to the speaker audio cable is disconnected.
Troubleshooting II: sound card issued
Excessive noise. There are common causes of this failure:
1. Card is not correct. As the chassis manufacturing accuracy is not high ample, the sound card contractor or installed outdoor the damper caused by bad sound card expansion slot can not be closely integrated with the motherboard, sound card can be seen visually on the This phenomenon
In the ISA card or PCI card has, are common mistakes. Generally accustomed pliers amendment.
2. Active speakers Speaker input connected to the sound card output. For the lively speaker, should be connected to the sound card Line out side, it has not been
output signal on the sound card amplifier, noise was smaller
And more. There is only one sound output is still Speaker Line out jumpers on the card depends on the determination, the factory default mode is often Speaker, so the jumper to disconnect the sound card.
3. Windows comes with a bad driver. Sound card driver is installed, choose Use the If you have installed the Windows driver that comes with the optional → voice, video and game controllers
often
See Failure three: sound can not I once had a sound card under Windows 98 with the original driver disk to install the drivers how can pretend not to, and had to use Creative SB16 driver instead, everything is normal. Later upgrade to Windows Me, not back to normal with Windows 2000 (full edition) comes with the sound card driver was normal.
2. The most difficult problem than the Windows 9X Plug and Play devices under test has chosen to given a free hand to assist you install the driver, the driver side is not used, then, each time you cancel out reloading will repeat this problem, and can not Pieces Hundred percent efficacious, have saved innumerable lives ... ... the sound card of way, modify the registry can attain the same purpose.
3. PnP sound card does not support the installation (also applies to not use the PnP mode PnP sound card installed): Go to Windows
Search for new hardware? CD silent
1. Completely silent. With Windows 98, Use a 4-pin CD-ROM audio cable to connect the analog audio output and sound card
On the CD-in to this line in the purchase of a CD-ROM will be included.
2. there is only one aisle silent. I generally drive about two-wire output signal, the middle two lines to ground. As the audio signal line 4 line color is generally different from the color line to find one to one interface. If the sound card only
Each interface or an interface does not mate with the audio cable, audio cable wiring had to change the order, usually only one of two lines of the change can be.
Troubleshooting five: PCI sound card sonic prosperity
PCI cards are generally used because of technical causes hanging in the Bus Master PCI bus read and write on the hard drive, mouse and other operations to enlarge the background noise
reason. Solution: turn off
Bus Master PCI graphics capabilities, and replaced with AGP graphics card, sound card for the PCI slot.
Common Fault 6: normal recording can not first check
Is there nought wrong with the microphone jack into the other, and second, double-click the little speaker, select list Then in the If the Try the
so common
Barrier seven: Can not play music, Wav, Midi Wav Music
can not activity melody are quite rare, constantly deserving to Ge, you can maim a; can not activity MIDI files may have the following 3 possibilities:
1. Early ISA sound card may be due to 16-bit mode 32-bit mode is not compatible with the MIDI playback is not caused by normal, By installing the software wave chart
way should resolve
2. Now they use the renowned PCI sound card wavetable synthesis technology, if the MIDI playback is not part of it is probably because you do not have to load the appropriate wavetable sound library.
3. Windows volume control in the MIDI channel is set to silent mode.
Troubleshooting eight: PCI sound card to use in WIN98 some unusual
Users complained that the sound card driver installation process anything is normal, no device conflicts occur, but the following is not silent in the WIN98 or cause other problems. This phenomenon usually occurs on the PCI sound card,
Please check the installation process you plug in the PCI sound card which of the PCI slots. Some friends for thermal attentions, like the sound card plug away from the AGP slot, approach the ISA slot that several PCI slots
In. Problems often appear here, because there is a Windows98 Bug: sometimes only the correct identification and inserted in the PCI-1 PCI-2 card slot two. In the ATX motherboard close to the AGP
The two PCI is the PCI-1 and PCI-2 (on the contrary in some of the ATX motherboard, close to the ISA is the PCI-1), so if you do not have the PCI sound card installed in the correct slot, and asked
Questions will produce a.
Memory
computer memory is one of the most important parts, no mistrust about its role,
Asics Onitsuka California 78, then the memory of the most common faults are what it?
often
See Fault 1: boot no display
memory because the recurrence of such failure is usually because the memory and the motherboard memory slot is bad cause, by the time smear his finger back and forth with the eraser part of the solution can be
Decision problem (do not use alcohol and other cleaning), there is the motherboard memory slot or memory corruption problem will cause such failures.
Because memory causes no show boot failure, host speakers typically
Long beep (for the Award Bios is concerned).
Troubleshooting two: Windows Registry damage often for no cause, suggesting that this requires the user to restore
Classes because of memory failures are generally caused by poor quality, difficult to be repaired, only replaced one way.
Troubleshooting III: Windows often automatically enter the safe mode
Such failures are generally due to the motherboard is not compatible with the memory or the memory caused by poor quality, common in high-frequency memory to memory that does not support this frequency of the motherboard, you can try to reduce the period within the CMOS settings
Keep reading to see whether the speed problem, should not do, only replace the memory of it.
Fault IV: random crashes
such failures are generally due to the use of several
Different chips of memory, due to the memory of different speeds to produce a time difference resulting in decease
machine, which can reduce the memory speed in the CMOS settings to be addressed, among the same prototype only use
Deposit. Another feasibility is that memory is not compatible with the motherboard, such phenomenon is generally rare, the other is also likely that adjoin with the motherboard memory computer promiscuous crashes caused by bad. 01
common Fault 5:
Memory to addition system resources, but afterward depressed
such phenomena are generally not compatible with the memory because the motherboard cause, common in high-frequency memory memory does not support this frequency fjust aboutme of the motherboard memory
, When such a failure you can try the COMS memory speed will be set at a low point try.
Common Fault 6: Run some of the software often prompts
memory
This phenomenon is generally due to not enough free space on the system disk, you can delete some useless files, leaving some space can be generally preserved at
300M or so.
Troubleshooting
Seven: Install Windows to boot from the hard drive to detect disk space, memory
reminded such a failure is usually due to user combine in the config.sys file
The emm386.exe file, as long as it can stop out the problem. CD-ROM drive is
microprocessor hardware accessories in 1 of the shortest life. In fact, there is still a lot of scrap steer
Great value in use, a little upkeep at a time what you can. This often do not have any progressive perception of the radio, do not need everything too complicated repair tools and matters. As long as you carefully inspect the omens
And execute the following with reference to some troubleshooting, I deem you can restore the antique drive or the age
a common fault: when the hard drive light is always flashing work
This is an fantasy, it is not. Hard disk light flashes because the same drive and hard disk connected to an IDE interface, CD-ROM drive working light also controls the result. Drive unit can be connected to a single IDE interface
On.
Troubleshooting II: In the Windows environment on a CD-ROM when However, Windows 32-bit disk access on the CD-ROM to a certain extent. Most CD-ROM drive connected to the IDE interface is not supported
Windows 32-bit disk
Access, so that Windows generates one interior error and crashes. Into Windows, the Save The peccadillo.
Troubleshooting III: optical drive not properly read the disk, displayed on the screen: ?
In this case,
Should detect viruses, use antivirus software on the machine to check the virus, the virus can not find the file if the editing software to open root directory of C under the CONFIG.SYS Driver and the driver was destroyed, and processing, text editing software can also be used to view There are
Troubleshooting four: drive to use when
Read and write errors or diskless tips
for this phenomenon is mostly set in place, had not operate on the drive caused the failure. All operations on the drive will need to wait for the disc are light display
To be like the bit operation. DVD playback when the time should be transferred to naught and back plate, so you can avoid the above error.
Fault 5: During the screen when playing VCD films
Pause or wreck phenomenon
check the AUTOEXEC.BAT file If so, you should

Fault Seven: boot drive not detected or detected failure
This may be due to drive
Data cable connector is loose, damaged or the hard disk drive data cable jumper settings error caused encountered this problem when
waiting, we should first check the drive's data cable for lax connections, if found not plugged in,
Will be re-inserted, seated. If this still does not solve the problem, then we got a new data can be put on line to try. At this time if the fault still exists, we need to check the CD-ROM jumper
Set, if there is an error, change it to.
Mouse
mouse failure thinking and maintenance is relatively simple, most of the fault for the bad interface or buttons, broken, filthy mechanical positioning system
Pollution. A small digit of failures for the internal components or circuit Weld mouse, which is primarily found in certain low-quality products, especially in the light-emitting diode, IC circuit damage to the majority.
a general fault: can not find the mouse
1 mouse completely damaged and need replacement mouse.
2. mouse connected to the host serial port or PS / 2 mouth exposed, carefully pick a good line after rebooting.
3. motherboard serial or PS / 2 ports from getting damaged, this position is rare, if this is the case, had to replace a motherboard or a reg code port on the multi-purpose card.
4. mouse line is bad, this is the most common. Poor contact points as in the mouse inside the wire and circuit board connections. Failure at a time not another PS / 2 connector at the general maintenance of it is not difficult. Usually due to
Relatively short lines, or contrast the mouse lines are messy and guide to pull hard because the solution is to open the mouse, then use a soldering steel to solder weld. Another circumstance is inside the mouse cable is bad, is because of the time
Caused by the aging caused by long, this failure is often difficult to find, replace the mouse is the fastest solution.
Troubleshooting II: the mouse to display, but can not move the mouse
Flexibility decline, not as peremptory the mouse arrow, but slow, incorrect positioning, or simply can not be moved. This is mainly because of the mechanical positioning of the mouse scrolling axis in the collection of redundant filth and
Lead to transmission failure, resulting in rolling is not malleable. Focus on maintenance inside the mouse X and Y axes of the transmission on. The solution is to open the plastic ball locking plate, remove the mouse pellet to roll, with a clean cloth dipped in
Of detergent for cleaning of plastic ball, friction shaft can be cleaned using alcohol. Axis at best a few drops of sewing machine oil, but it must be scrupulous, do not flow to the friction surface and the code plate on the gate gap. Will remove all sand
After the flexibility to restore the mouse ever.
Troubleshooting III: the mouse button failure
1. the mouse button without action, this may be because the mouse buttons and board too distant away from the micro-switch or switch after a period of Click use of a reduced aptitude to rebound. Open the mouse, the mouse buttons beneath a thick glue
Moderate plastic film thickness is resolute according to actual needs, can be prone of after use.
2. mouse clasp can not be normal up, this may be because when the key alternate in the bottom of the bowl-shaped micro-fracture caused by exposure to film, primarily the long-term use of plastic is easily broken reed. If a three-button mouse, you can be in the middle of
It removed a key emergency. If it is good quality elemental brand-name mouse, you can weld, the open micro switch, carefully clean the contacts, some of the grease, the flasks can be used.
key keyboard
Plate in the course, failure of performance of a variety of fashions, the causes of many. A bad failure, mechanical failure with their own keys, as well as logic circuit fault, Weld, artificial welding, sealing off the oxygen and metal hole
Of other faults. Maintenance according to the analysis of different symptoms to determine, find out the cause of the malfunction, make the appropriate repairs.
a common fault: some keys on the keyboard, such as the space bar, return key does not
Work, sometimes, correction shall be entered many times ahead - one or two characters, and some

this failure as a keyboard Students. A keyboard key to card phenomenon caused by the following two reasons: one reason is that the Caps carton below column position offset, making the keycap is pressed and the key is not stuck in the body shell caused the bounce card key, This causes multiple
Born in or near the new keyboard on the keyboard. Another reason is the key long-term use, the spring-elasticity becomes poor, and shrapnel shot by friction becomes larger than the bounce caused by card key key, this occurred because
In the long-term use of the keyboard. When the keyboard appears when the card key fault can be allocated under the keycap, and then pressing the press pry. If the bombs do not lever up or by fatigue, is caused by the second, otherwise the first cause. If the
On the keycap and the key causes the body shell stuck as its size is equal to or slightly larger
On the key body size, and location of the opening by a wand through the wand allows free corridor of ammonium square hole, it sets in at pole, plug in the keycap; gasket to stop with this key body stuck with the keycap , you can fix problems button; if due
Spring fatigue, shrapnel resistance change causes a large card key failure, then the body can be special key to open, a little stress return spring to restore elasticity; remove the shrapnel will be key to body revitalization. By removing the shrapnel and reduce bounce by rod resistance
So that the key failure has been restored.
Troubleshooting II: some characters can not enter.
if only certain characters can not enter a key, the key may be invalid or joints
Weld. Inspection, in agreement with the method depicted above to open key

Fault IV: keyboard input and screen display of the characters are inconsistent.
such failure may be due to the phenomenon of short circuit caused the circuit board
, And its performance is shown by the key is the same as the other characters, this time can be measured multimeter or oscilloscope to determine the point of failure after the repair.
Common Fault 5: Press a button to produce a
String of multiple characters, or when the character key bounce.
This phenomenon is caused by the logic circuit fault. First select a column of characters, if the enter key of a row without a column, may produce a number of other
Character phenomenon; if the one with the Enter key, will have a skip and can not be the last character of the phenomenon into the system, check with an oscilloscope logic circuit chip, the chip to find fault with the model after replacing the new chips, troubleshooting.
Modem
often
See fault a: 56K Modem not up to the 56K. This problem can be from the following considerations:
1. The actual 56Kmodem can only reach maximum speed of 53K or so,
Asics Revolve LE, to consider the various effects, 56Kmodem speed is generally between 45-53K.
2. Modem telephone line to a large extent inspire the transmission rate, if poor quality telephone lines, line voltage instability, 56K Modem
on the last of less than 56K; another extension using the Internet, but also
Will affect the Internet speed.
3. not installed the correct driver.
4. and ISP with another protocols, only your Modem and your ISP accord is the same, Modem 56K will meet the criteria.
exclude the on reasons, your 56K Modem is still many faster than 53K, this is your Modem hardware problems can be thought a replacement or repair
.
two common faults: Modem often dropped, resulting in
Dropped the publish may have several reasons:
1. Poor quality telephone line;
2. If the data terminal prepared (DTR) signal period exceeds Modem invalid default values will cause dropped;
3. If your call has a Modem their quality and compatibility problems among different Modem Modem is caused by a common cause of dripped cries.
Troubleshooting III: Modem no dial
No. tone
when surfing the network in the dead of night, in array to make the dial intonation does not influence the others nap, through the applicable AT mandate to change: You can use the ATM0 no dial set Modem
Sound, and ATM1 set Modem from dial-up linkage as a dial intonation. Volume selection for the following bid you can change, ATL0 (low volume), ATL1 (cheap volume), ATL2 (tenor
Volume), ATL3 (high volume).
Fault IV: fax speeds up to fewer than 14400
Modem maximum fax rate is 14400, and fax
Only when the rate of 9600. This is because most of the fax machine to send and receive rates are
is 9600, and only use the rate of 14400 or 33600 fax, Modem fax speed
Rate will reach 14400.
Troubleshooting five: Modem can not dial or connect

Capacity calculation is to use the printer's internal electronic counter for addition (especially in the color of ink used on the statistics), when the counter reaches a decisive value, the printer ink is used to determine. In the ink cartridge replacement
Process, the printer will behave its internal electronic counter reset, thus confirming the installation of a fashionable cartridge.
Solution: Turn on the power, the print head pushes to the ink cartridge replacement location. The cartridge
After installation, get the printer to charge the ink, ink charging process is complete, troubleshooting.
Troubleshooting III: treatment of head
soft soft plug plug plug means is due to manifold
Causes the viscosity of the ink in the nozzle due to break bigger fault. Generally with original ink cartridges can be retrieved after repeated washing, but this is path too consumed ink. The easiest access is to use your hands to be empty cartridges
Nozzle cleaning. Before cleaning with an empty cartridge, first using a probe to try out residual ink inside the cartridge, the detergent the better, then increase the cleaning solution (accessible aftermarket). Filling cleaning fluid should be in a clean environment,
Will add a good cleaning fluid cartridge according to the normal operation of the printer machine, printer cleaning by key continually be cleaning. Use of the residual ink cartridge cleaning fluid mingled with the light color print test, put on a good ink after normal
Box can be used.
Troubleshooting four: Clean the pump nozzle printer troubleshooting
printer cleaning something erroneous with the pump nozzle is more, is the main factor causing the plug
One. Printer cleaning printer head of the pump nozzle protective play a decisive role. After the car back to the morsel head to clean the pump by a feeble mouth nozzle exhaust treatment on the nozzle seal conservation. Or install a new cartridge in the printer nozzles
There are loosened, the suction pump to the bottom of the machine through its exhaust nozzle, the higher the better accuracy of the work of the mouth. However, in tangible use, its performance and wind tightness due time, the dust and ink remnants in the mouth
Coagulum increases. If the user does not audit or clean it regularly, it will keep you out of some of the print head failure.
maintenance of this part of the method: Remove the printer cover
Remove the car, using a needle wash them inhaling pure water, of special note, embedded within the pores of the mouth to fully clean the gasket. This should remind the user to clean this component, do not use ethanol or methanol to clean them,
This will cause the component dissolved in the mosaic of the porous gasket deformation. Also to advert is that inkjet printers should be kept away from heat and dust of the work environment, only a good working environment to ensure long-term regular use of the machine.

significant variation in the use of inkjet printers will be the use of frequency and timing of the enhancement of print accuracy becomes aggravate. Inkjet print head
There is also life. Generally use a new nozzle from the beginning to the end of life, the more smoothly if you could not see any fault, then, is the 20-40 cartridge usage life. If your printer has been used for a long time now
Print less accurate, you can replace the cartridge method to try, if for a few cartridges, print output results are the same, then you are this printer's nozzle to be replaced. After replacing cartridge if there is a change,
Instructions you may have to use poor quality ink non-original ink.
If the printer is new, print the results can not satisfy you, often printed line is not remove, txt, graphics twisted
Oblique, the outer border of fuzzy text graphics, print out the ink control synchronization accuracy, this means you may buy a ######## ink cartridges or use non-original products, it should be replaced immediately.

Properly connected. If the recorder with other IDE devices share an IDE cable, the need to assure that two devices can not be set to Set to
Troubleshooting II: the success of using analog recording, the actual recording but failed
burner provides Adequacy of recording disk space environmental conditions, but can not burn the disc to be tested if there are problems and burner laser power and disc read-write head matches, and so on. In view of this, that But the real burning fails, the burner and blank discs are not compatible between the good, the following two methods can be used to re-try it:
1. Reduce the burner write speed, 2X recommended the following;
2. replace another brand of blank discs for burning operations. There's another reason for this phenomenon is the phenomenon of laser power attenuation caused by read-write head, and if you use the same mark of disc recording, the first time
Are normal, then it may be read-write head on the power diminution can be sent to the vendor maintenance.
