Now the printer has become a computer product that is often used in people's work and life, and because they often use the products, people often encounter such a problem, and if these problems should be repaired, not only Some money, more important delays. In fact, the inside of the printer is not complicated, and the general problem users can solve themselves, and I will introduce some simple maintenance methods to you.
Repair the printer problem before repairing the printer. After the printer has problems, first use the printer self-test system to perform detection, it may be judged by the indicator of the printer or the sound of the buzzer, where the indicator can indicate the most basic fault, including the lack of paper, Ink, no power, etc. The judgment of the beep is mainly on your hearing. For example, most printer berers will be ready to start printing, and the printer has faults with a short sound. Second, a line observation can be performed, from the start of the detection printer cable (including port, channel, print line detection), then analyze the internal structure of the printer (including paper jam, feed port, printhead, etc.), see if the part works correctly, Lock the associated components for different fault conditions, then determine the components of the problem. Again, you can use the test method to print or local test printer parts, and see the cause of the fault. Of course another faulty of the printer is software failure, similar failures need to be resolved by upgrading drivers or accessing its official website.
Below we will make a description of some printers' failures.
First, the printing effect is different from the preview
This is generally in the text editor, common like Word or WPS2000, etc., it is clear that it is uniform in the preview, but prints out to find that some fonts are overlapping. This situation is generally due to improperly adapted when editing, the method of solving is to change the paper size in the file "page properties", paper type, number of words, etc., usually can be resolved.
Second, printing is not clear
This problem is usually very common in usual use of the printer. Generally, this situation is related to hardware failures. It is generally important to pay some key parts of the printer. In this case, we have an inkjet printer as an example. If the print color is blurred, the font is unclear, and the fault can be locked in the nozzle. First, the printhead is automatically cleaned. If there is no success, it can be used with soft water absorption. Strong paper is wiped near the printhead; if the above method still can't solve it, only the printer driver is reinstalled.
Third, you can't print big files
This situation happens in the laser printer, it may be normal when printing a small file, but when printing a big file, it will crash, this problem is mainly software failure, you can view the remaining space on the hard disk, delete some Useless files, or query the number of printers to expand.
Fourth, the printer does not respond after selecting print
When this is generally encountered, the system usually prompts "Please check if the printer is online and the cable connection is normal." General reasons may be that the printer power cord is not inserted; the print cable is not properly connected; the contact is poor; the computer parallel is damaged. The solution to the solution mainly has the following:
1. If it does not start normally (ie, the power light is not lit), first check if the printer's power cord is properly connected, turn the power cable again in the shutdown state, and change it to a power outlet to see if it can be resolved.
2. If the printer can start properly after pressing the power switch, go to the BIOS settings to see the pair of parallel settings. The general printer is used by ECP mode, and some printers do not support ECP mode, and can be used in ECP EPP, or "Normal" mode.
3, if the two methods described above are invalid, you need to focus on the print cable, turn off the computer first, pull the two heads of the print cable to re-insert it, pay attention not to bring an electric plug. If the problem, the problem cannot be resolved, change the print cable to try, or use alternatives. Five, printing is incomplete
If you encounter such a problem, you can definitely be caused by software failure. You can change the print interface settings in Windows95 / 98. Select "Start → Settings → Control Panel → System → Device Management → Port → Printer Port → Driver → Change Driver → Display All Devices, change the "ECP Print Port" to "printer port" confirmation.
Above I mentioned that several methods are more common on the printer, and in fact, solving the most important thing to solve the printer is still judging, as long as the cause of the fault can be found, we can repair it through a hardware method or software method. Of course, people will touch other faults when they actually use printers, so this requires you to master more printer's maintenance skills.
