Analysis of printer jams

What caused the printer to malfunction? Through careful study in peacetime, the following simple, effective, and practical maintenance methods are summarized for reference by computer operators in the printing industry.

A foreign body in the printer

As laser photocopying and advanced equipment, it has the characteristics of high sensitivity, stable performance, etc. Therefore, it has higher requirements for the surrounding environment, hygiene, temperature and other aspects. When the sample is made, the printer will not work due to paper embrittlement or other reasons. Because of the high sensitivity of the laser printer, there is something in it, and it mistakenly believes that the paper is ready, but when the paper board is lifted and the suction wheel rotates , it is empty because the paper is too small to transmit. The computer prompts The printer is malfunctioning. In the same way, foreign objects such as paper and rubber in the printer , including some dust and scattered toner, can cause the printer not to be large.

Maintenance method: When this happens, immediately open the printer cover, and then use the tweezers to clamp things like hidden shreds inside, and then use leather tigers (maintenance special tools to remove the dust on the parts). The other tiny dirt inside is blown clean, if the dirt is stuck on the shaft and cannot be blown off, it can also be rubbed with cotton and rubbing alcohol. Remember, you can't scrub with cloth or water, otherwise the printer won't work because of dampness.

Second, the internal temperature of the printer is too high

When the printer is turned on for a long time, and when the printing paper is too much, the heat output is not good because the printer keeps working and the output channel temperature is too high. When the printer's temperature is too high, there will be such a situation: When the computer is finished reading the disk, the paper is successfully input into the machine, but no longer print samples, and the host has been completed. what happened? After opening the cover, the original prints were squeezed together and there was a small cabin out of the room. This is because the printer's temperature is too high. When the paper is printed out, when the paper is printed out, the leading end of the paper is hot and soft, losing its hardness, so it can't move forward, and the rear paper is under the forceful transmission of the transmission wheel. All the roads were forcibly squeezed together and became toilet paper, unable to read and proofread.
Maintenance method: In this case, immediately stop using, shut down, and open all covers of the printer so that it can fully dissipate heat. At the same time, you can also use cotton, alcohol to gently wipe the parts that are overheated and overheated. It cools as soon as possible.

Third, the host menu content design error

Most of the laser photocopying center, the host computer is connected with the printer and the phototypesetting machine. If the photojournalist has just used it to send the film, the internal program setting has not been changed (ie, the condition required by the original printer output state has not been restored). At this time, the printer command does not work because the menu command differs from the command required by the printer.

Maintenance Methods: In this case, use the mouse to click menu, so the menu command back printer output up, to which some of the menu contents to be modified. If the layout is on the left and right borders are 0, the peripheral name is not Canon but proofreading.

Fourth, the floppy disk is bad or bad

When you copy a floppy disk has been broken off or some bad sectors, inserted into the host floppy drive, use the mouse to click on the menu, so the host to read the disk, the floppy drive light is on, but suddenly went out, the host prompt to "Ee" (bad ) This means that the floppy disk you are using is corrupted. The disk information cannot be passed to the host center command system, so the host does not work.

Maintenance method: At this time, you need to replace a floppy disk to copy the sample again, or format this bad disk, and then copy the content you need to reissue.

Five, the printer itself is faulty

When you use the host to send samples, you are using the correct floppy disk and host, but the printer still does not work. There is no dirt inside the printer, and the temperature is not high. At this time, you should carefully observe the indicators on the printer and check if there are any abnormalities.

There are three indicators on the printer (indicating non-normal warnings), and one is a toner indicator. The indicator is on, indicating that the printer has run out of toner and needs to refill the toner. The other is the paper-discharge lamp. When the light is on, it indicates that the printed paper is not set well. The front of the paper does not stand against the printer. The feed roller of the printer cannot grasp the paper and cannot pass forward. The third is the signal interruption indicator. This light is on, indicating that the fault occurred in the middle of the last printing and the printer is in a semi-active state. At this point, the printer should be turned off, then restarted, and the printer should be returned to the initial state before it can resume operation.
