printer
In the office, the ink jet printer is used in a more convenient one P apparatus. Inkjet printers due to the use, maintenance, operation and other improper reason often be some failures, how to solve the problem of interest to users. Here we put summed up the daily work of common faults and treatment, we want to help.
A common fault: When printing ink scarce, illegible treatment, most of the failure was due to long-term unused printer or other reasons, resulting in ink delivery system disorder or nozzle clogging.
Excluded: If clogging of the nozzle is not very bad, then the cleaning operation can be performed directly on the printer. If still no effect after repeated washing, the ink cartridge may be scored (for non-integral printer cartridge nozzle, the nozzle need to win, but requires careful), the nozzle in warm water soak for a note, the board must not portion is also immersed in water, or else, with absorbent paper sucked stained water droplets, and then washed several times with a nozzle mounted on it.
Troubleshooting II: After the replacement cartridge, the printer boot "ink to make" on panel lights processing
Normally, when the ink has run out "ink exhausted" lamp will light. After replacing the ink cartridge, "ink to make" on the printer panel lights brighter, such a failure occurs, one possible cartridge is not installed, another possibility is to win the old cartridge itself in the off state, a new replacement cartridges. Because re replaceable ink printer ink delivery system will charge the ink, and this process will not be in the off state, so that the printer can not detect the ink cartridges are reinstalled. Further, some printers for metering ink capacity is to use the printer to internal electronic counter for counting (especially in the statistical amount of color ink), when the counter reaches a certain value, the printer determines the ink end. In the ink cartridge replacement process, the printer will reset the electronic counter to its inside, thus confirming the installation of a new cartridge.
Solution: Turn on the power, moving the print head to the ink cartridge replacement position. After installing the ink cartridges, printer ink charging so that, after the end of the ink charging process, troubleshooting.
Troubleshooting III: Sprinklers soft plug processing
It refers to a soft plug plug due to various causes ink viscosity becomes large due to a disconnection fault in the nozzle. Original ink cartridge is generally used after repeated washing can be restored, but this approach is too wasteful ink. The easiest way is to use your hands empty cartridge for cleaning head. Before empty cartridges washed with, first the ink cartridge with a needle to try to find the residual ink, the better the cleaner, the cleaning solution was then added (commercially available accessories). When the cleaning liquid filling, should be performed in a clean environment, good cleaning solution will be added on the printer cartridge by the normal machine operation, according to the printer of the continuous cleaning key be cleaned. The ink cartridge using the ink cleaning liquid residue was mixed light color print test, the ink cartridges normally put on it after use.
Troubleshooting four: Troubleshooting printer cleaning pump nozzle
Printer cleaning pump nozzle acted up more, and it is one of the main factors of the plug. Printer cleaning pump nozzle to protect the printer heads play a decisive role. After the head carriage return, to the head of a weak pumping processed by the washing pump nozzle, for sealing the nozzle protection. When installing a new ink cartridge or the printer nozzles has broken, the lower end of the machine is evacuated by a suction pump to its head, this nozzle working accuracy as high as possible. However, in actual use, its performance and air tightness due to the prolonged time, dust and ink residue in the mouth of this coagulum increases. If the user does not inspect or clean it regularly, it will make your printer nozzle constantly out of some failure.
This method of curing the member: removing the cover of the printer away car, with its needle suction of pure water rinsing, cleaning of the particular insert within the well mouth microporous pad. Here to remind the user, this cleaning member, do not use ethanol or methanol to clean it, this will result in this component in the mosaic deformation of a microporous pad dissolution. Also to mention is that the ink-jet printer to be kept away from heat and dust of the work environment, only the good working environment to ensure the normal use of the machine for a long time.
Troubleshooting V: detecting ink line normal and significant deterioration of printing accuracy processing
In use the ink jet printer due to prolonged use of the frequency and timing of the printing accuracy deteriorates gradually. Heads of jet printers is also a life. Generally a new head from the start of use to the end of life, if not fault anything more smoothly if, that is, the amount of life 20-40 cartridge. If your printer has been used for a long time, and now the poor precision printing, you can use the method to replace the ink cartridges to try, if for a few cartridges, print output results are the same, then you this printer heads will be replaced a. If there is a change after replacing the ink cartridges, instructions may have the cartridge you are using poor quality non-original ink.
If the printer is new, the printed results can not satisfy you, often print line is not clear, graphical text skew, fuzzy boundaries graphics to text, print out the ink control synchronization accuracy, which means you may buy the fake cartridges or use of non-original cartridge products, it should be replaced immediately.
Troubleshooting Six: trolley dislocation meet processing
Inkjet printer trolley track by two sets of precision alloy of copper powder in combination with a round shaft to complete the slide. While walking there is a small car designed and installed to supplement the lubricating oil Felt shaft, but the environment we live in dust everywhere, a long time, due to air oxidation, dust damage the shaft surface lubricant aging failure, continue to use the printer at this time if, due to the shaft will be increased friction with the copper sleeve trolley dislocation caused, resulting in unusable until the collision front.
The solution is: Once this failure should immediately turn off the printer, hand car will not push back the return of parking spaces. To find a piece of sponge or felt dipped in oil saturated sewing machine oil, forceps rub back and forth on the spindle. Preferably the spindle is removed, the cleaned oil, the effect is best.
Another car is because damage to the device due to meet. Car parking space above the printer has a photosensor, which is an important element to provide a reset signal to the print carriage board the printer. If this component is too large or damaged by dust, the printer carriage return signal can not be found due to encounter the front, and unusable, the device needs to be replaced when a general fault.
monitor
A long time for display, a variety of small problems will follow. Experts believe that to solve these little problems is actually quite simple, with a pair of eyes can see the fault lies.
A common fault: the computer monitor screen just machines shake so badly, and sometimes even the icons and text are not clear, but after twelve minutes will return to normal.
这种现象多发生在潮湿的天气，是显示器内部受潮的缘故。要彻底解决此问题，可使用食品包装中的防潮砂用棉线串起来，然后打开显示器的后盖，将防潮砂挂于显象管管颈尾部靠近管座附近。这样，即使是在潮湿的天气里，也不会再出现以上的“毛病”。
常见故障二：电脑开机后，显示器只闻其声不见其画，漆黑一片。要等上几十分钟以后才能出现画面。
这是显象管座漏电所致，须更换管座。拆开后盖可以看到显象管尾的一块小电路板，管座就焊在电路板
上。小心拔下这块电路板，再焊下管座，到电子商店买回一个同样的管座，然后将管座焊回到电路板上。这时不要急于将电路板装回去，要先找一小块砂纸，很小心地将显象管尾后凸出的管脚用砂纸擦拭干净。特别是要注意管脚上的氧化层，如果擦得不干净很快就会旧病复发。将电路板装回去就大功告成。
常见故障三：显示器屏幕上总有挥之不去的干扰杂波或线条，而且音箱中也有令人讨厌的杂音。
这种现象多半是电源的抗干扰性差所致。如果懒得动手，可以更换一个新的电源。如果有足够的动手能
力，也可以试着自己更换电源内滤波电容，这往往都能奏效；如果效果不太明显，可以将开关管一并换下来。
常见故障四：显示器花屏。
这问题较多是显卡引起的。如果是新换的显卡，则可能是卡的质量不好或不兼容，再有就是还没有安装正确的驱动程序。如果是旧卡而加了显存的话，则有可能是新加进的显存和原来的显存型号参数不一所致。
常见故障五：显示器黑屏。
如果是显卡损坏或显示器断线等原因造成没有信号传送到显示器，则显示器的指示灯会不停地闪烁提示没有接收到信号。要是将分辨率设得太高，超过显示器的最大分辨率也会出现黑屏，重者销毁显示器，但现在的显示器都有保护功能，当分辨率超出设定值时会自动保护。另外，硬件冲突也会引起黑屏。
