The printer's broken, it's a coup.

In the daily life, we must have encountered a printer failure, this time if the maintenance staff to repair, may delay the important work. Based on this need, this article prepared a number of not need complex technology and equipment can be completed on their own repair methods, I hope to help.

　　Basic methods of maintenance

When there is a problem, the first is to use the printer self-test system for testing, may be the printer's own led or the sound of the buzzer to judge, which led can indicate the most basic fault, including the lack of paper, ink, no power and so on. And the buzzer is mainly rely on your hearing, such as most of the printer buzzer with a bell to indicate ready to start printing, to express the short chirp to indicate a printer failure. Second, the line can be observed from the detection of the printer cable start (including ports, channel, print line detection, and then analyze the internal structure of the printer (including supporting paper racks, feed ports, printing first Class), to see if the components are working correctly, for different failure conditions to lock the relevant parts, and then determine the problem of the parts. Again, you can use the test method to print the test page or partially test the parts inside the printer to see the cause of the failure.

It is worth mentioning that many times a software failure can be resolved by upgrading the driver or visiting its official website.

　　Maintenance of the practical skills

In the use of the printer process, we often encounter the problem is nothing more than a few cases, the following we analyze, I hope you grasp the method, extrapolate.

　　1. Not clear print handwriting

Whether it's a stylus printer, an inkjet printer, or a laser printer, this is usually related to a hardware failure, and we can focus on the key parts of the printer by using line-observation. For example, ink-jet printer, encountered in the printing color blurred, the font is not clear, you can lock the head in the nozzle, the first machine automatic cleaning (according to the manual), if the long time does not print words will be more cleaning several times. You can also carefully remove the cartridge, close to the print head of the place with soft absorbent strong paper clean. If it is not resolved, it may be the problem of the driver, generally the printer's driver reinstall again on the line.

　2. The printing effect is different from the preview

When you are editing a file with a printer, such as word or WPS2000, clearly in print preview arranged in neat words, can be printed on the paper there are some overlapping text, this phenomenon is generally due to improper settings in the editing, change the file "page properties" in the paper size, Paper type, each line of words, etc., can generally be solved.

　　3. The printer does not respond after issuing instructions

This is often the case when you are prompted to "check to see if the printer is online and the cable is connected properly." After checking, the reason may be that the printer power cable is not plugged, the print cable is not properly connected, the contact is bad, and the computer's port is damaged. If you do not start the normal (that is, the power light is not lit), first check the printer's power cord is properly connected, in the shutdown state the power cord to plug again, and a power outlet to try to see whether the solution. If the printer can start normally after pressing the print power switch, go to the BIOS settings to look at the port settings. Generic printers use ECP mode, and some printers do not support ECP mode, which can be Ecp+epp, or "Normal" mode. If the problem has not been resolved, then focus on checking the printing cable, first the computer off, the printing cable at both ends of the pull down to plug in, pay attention to not live plug. If the problem is not resolved, try a different print cable, or use a substitution method.

　　4. Print large file crash

Some laser printers are normal when printing small files, but they crash when printing large files. This is obviously a software failure, you can look at the remaining space on the hard disk, delete some useless files, or query the number of printer memory, whether it can be enlarged.

　5. Individual fonts do not print out

This is also a software failure, sometimes always use several common font and font size, recently changed several fonts, found that the font does not come out or the individual words are not. You can remove the problematic font on processing. Delete font First select a font, and then choose "File =〉 Delete", remove the previous font. Then double-click "My computer → control panel → font → file → install new font".

　　6. Partial printing or printing incomplete

Judgment is a result of software failure, you can change the print interface settings within the system, select "Start → set → control Panel → system → device management → port → printer port → driver → change driver → show all devices", and then confirm "ECP print port" after "printer port".

To solve the printer's fault, the key is to determine the fault parts, and then find out the cause of the failure, and then use the hardware method or software methods to deal with, through continuous practice, can master more of their own printer skills, I hope that friends continue to learn to continue efforts.
