Correct maintenance method of printer

With the use of printers getting longer and longer, there are more and more faults and internal problems. Do you know the methods and skills of printer maintenance? The following is a careful arrangement of some correct maintenance methods for printers. I hope it helps you. Welcome to check.

Correct maintenance method of printer

First, check whether the printer is powered on. If the indicator light goes out, check whether the power cord and fuse are blown.

2. When the power indicator is normal, please check the print status indicator that shows communication data. Generally speaking, yellow-green indicates normal, and flashing red indicates paper jam, no paper or lack of ink. The flashing of double lights indicates that the ink cartridge or print head cannot be detected. It may be that the ink cartridge or print head is burnt out or has poor contact, or the ink flows out and gets stuck, resulting in internal short circuit between the print head chip and the ink cartridge detection chip. The two lights flash alternately, indicating that the waste ink bin is full of waste ink, and the counter of the print head chip or the ink cartridge chip needs to be reset. Clearing method of Canon printer-press and hold the power switch, and then insert the printer. When the power indicator light is on, quickly press the paper output key twice with the other finger, and then release the power switch at the same time for manual reset. Manual zeroing is usually not thorough. If necessary, you can download dedicated or universal zeroing software online for zeroing.

3. If the two indicator lights are normal, but the printer can't print, you can check whether the printing task is a printing task by clicking "Print Output" at ordinary times, and check whether the computer is too slow to respond, and whether the user is too anxious to print, resulting in too many printing tasks and the printer can't respond, thus blocking the interruption and crashing.

Fourth, if you can print, but the printing effect is not good, please check whether the ink cartridge is out of ink or whether the nozzle of the print head is blocked. Blurred handwriting or blank space in the middle of printing is a problem of insufficient ink, blocked print head or no calibration. Just add enough ink to clean or correct the print head. Printing discoloration and color cast are caused by the lack of some ink in the ink cartridge or the blockage of individual nozzles or the mixing of different inks, which can be solved by adding ink correctly or replacing the ink cartridge; If the handwriting is incomplete, only half or more strokes are scratched, or the printing line is broken and lacks white stripes, the omission is unclear, or even printing can't be done, it is a print head jam fault, which can be solved by properly cleaning or soaking the print head.

5. Printer cleaning method: Select Advanced Maintenance in the toolbar of the printer driver property program, and enter the print head cleaning function for automatic cleaning. This cleaning method usually takes effect after three times. If it still doesn't work after five times of cleaning, don't automatically clean and waste ink; At this point, the machine can be disassembled for manual cleaning. The method is to disassemble the print head, soak it in pure boiling water at 80-90 degrees for half an hour or an hour, then wipe it with a paper towel and put it back in its original place.

6. If there is a paper jam, please turn the mechanical gear by hand and gently pull out the paper. Then check whether the paper feeding system is composed of paper feeding sensors and related mechanical transmission devices, and pay attention to whether the pinion is damaged or the paper is improperly placed. Sometimes the paper jam is caused by too thin, too wet or static electricity; Sometimes paper jams are caused by abnormal operation of ink cartridges or print heads; Sometimes paper jams are caused by system poisoning or damage and driver errors; Sometimes the paper jam is caused by paper scraps and sundries blocking the paper feed bin; Sometimes the paper jam is caused by the vertical and horizontal thickness adjusters of the paper, which is also called improper lever adjustment; Sometimes the paper jam is caused by insufficient power supply or unstable voltage of the driving circuit board. Therefore, specific problems should be analyzed in detail, and we should not tinker blindly or deal with them unilaterally.

Seven, if the printer does not respond, please check whether the printer driver is installed correctly. If it is installed correctly, please check that the printer is pointing to the correct port. After checking the wiring and drivers, make sure that the printer is in a "ready" working state and can print normally.

8. If all the above work has been checked and the printer still doesn't respond, please check whether there is waste ink at the bottom to wet the circuit board, which will lead to short circuit of the power IC integrated circuit, otherwise the print head will be seriously damaged and scrapped. In this case, a new or good print head should be replaced. The print head is out of control and automatically "hits the wall" as soon as it is turned on, which is caused by the wear or failure of the photosensitive belt behind the ink carriage.

Printer maintenance skills

First of all, the printing effect is different from the preview.

Usually, this happens in a text editor, such as word or wps2000. When previewing, it was clearly in a neat format, but when printing, some fonts were found to overlap. This situation is usually caused by improper settings during editing. The solution is to change the paper size, paper type and words per line in the "Page Properties" of the file, which can generally be solved.

Second, the printing handwriting is not clear.

This problem is very common in the usual printer use. Generally speaking, this situation is mainly related to hardware failure. When encountering this problem, we should generally pay attention to some key components of the printer. Let's take the inkjet printer here as an example. When the printed matter is blurred in color and font, we can lock the fault at the nozzle and automatically clean the print head first. If it fails, we can wipe it with soft absorbent paper near the print head. If the above methods still cannot be solved, you must reinstall the printer driver.

Third, you can't print large files.

This situation is more common in laser printers. Printing small files may be normal, but printing large files will crash. This problem is mainly a software failure. You can check the remaining space on the hard disk, delete some useless files, or inquire about the amount of printer memory and whether it can be expanded.

Four, choose the printer does not respond after printing.

Generally, when this happens, the system will prompt "Please check whether the printer is online and whether the cable connection is normal". The general reason may be that the printer power cord is not inserted correctly; The print cable is not connected correctly; Poor contact; Computer parallel port damage, etc. There are mainly the following solutions:

1. If it doesn't start normally, that is, the power light doesn't work, first check whether the power cord of the printer is connected correctly, plug it in again when turning off the power, and try another power socket to see if it can be solved.

2. If the printer can be started normally after pressing the print power switch, please enter the bios settings to check the parallel port settings. Ordinary printers use ecp mode, and some printers do not support ecp mode. At this time, you can use ecp+epp or "Normal" mode.

3. If the above two methods are ineffective, you need to check the print cable. First, turn off the computer, unplug both ends of the print cable and plug it in again. Be careful not to plug in the power. If the problem cannot be solved, please try another print cable or use other methods.

Verb (abbreviation of verb) is not completely printed.

If you encounter such a problem, you can definitely say that it is caused by a software failure. You can change the print interface settings in windows95/98, and then select Start → Settings → Control Panel → System → Device Management → Ports → Printer Port → Driver Change → Show All Devices, and change the ecp print port to printer port and confirm.

Maintenance method of laser printer

1, the room temperature should be controlled at about 22℃, and the relative temperature should be 20% ~ 80%; Avoid direct sunlight and chemical corrosion.

2. According to the command issued by the computer, the laser printer absorbs the charged toner on the photosensitive drum through photoelectric action, and then prints on the printing paper from the photosensitive drum, and heats the toner to dissolve the toner into the paper fiber to complete the printing function. Therefore, the photosensitive drum plays an important role in the whole laser printing process, so the maintenance of the photosensitive drum is more important. When the photosensitive drum works, the relative humidity should be kept at 20%~80% and the temperature should be 10~32.5℃. Avoid direct sunlight and try to keep the temperature and humidity constant.

3. The optical cassette in the laser printer is the key part of the printer. If the optical element is dirty, the digital information transmitted from the computer cannot be accurately converted from photoelectric to electrostatic latent image. Digital information of characters and images cannot be correctly transmitted to the carrier. Therefore, the uncleanness of optical elements is the main factor affecting the quality of carriers.

The optical elements and positions in the cassette are debugged and positioned with very precise and special equipment, and cannot be adjusted without special equipment. We should be very cautious and careful about the cleaning and maintenance of laser beam inspection mirror, optical fiber head, focusing lens and hexagonal prism. When cleaning the above parts and components, only bamboo tweezers, cork plugs and wooden sticks can be used to avoid damaging the metal or scratching the optical components during cleaning. In cleaning optical components, it is best to "dry clean" the hexagonal prism, and other components can be "dry cleaned" or "washed". Absolute ethanol can be used for water, wood or bamboo tools can be used for cleaning, and suede or medicinal absorbent cotton can be used to achieve the cleaning effect, but it is best to "dry clean" because "water-washed absorbent cotton" is easy to lose fibers and affect the optical effect.

4. The working process of the laser printer is to dissolve the toner into the paper through the photoelectric principle, so the paper of the laser printer must be dry and free of static electricity, otherwise it will be easy to block or blacken the printed document. Printing paper should be stored in an environment with a temperature of 65438 07 ~ 23℃ and a relative humidity of 40%~50%, so as to obtain the best printing effect.

5. If paper jam is found during printing, you can open the printer cover, pull out the paper stuck in the printer, and then close the printer cover to eliminate the fault. If there are frequent failures, please clean the corona wire and paper feeding track of the printer with a dry cloth.

6. The laser printer will produce ozone during printing, and the ozone filter must be replaced every 50,000 copies. Although the ozone filter looks clean at this time, it can no longer filter ozone. When the laser printer is placed in a crowded environment, the room is poorly ventilated, the printer exhaust port is facing the operator's face, and the ozone filter is used for too long, which will cause the ozone generated by the printer to be harmful to human body. At this time, it is necessary to improve the working environment of the printer and replace the ozone filter in time.

7. Wipe off the scraps of paper and dust in the laser printer with a dry cloth, and clean the corona wire. Only in this way can we ensure the normal use of laser printers and extend their service life.
