Copier paper jam how to deal with

Why does the copier jam
01
Separation claw wear

If the copier is used for a long time, the photosensitive drum or the separation claw of the fixing roller will be severely worn, and paper jams will occur. In severe cases, the separation claws cannot separate the copy paper from the photosensitive drum or fixing roller, causing the paper to wrap around it and cause paper jams. At this time, use anhydrous alcohol to clean the toner on the fixing roller and the separation claw, remove the blunt separation claw, and sharpen it with fine sandpaper, which can generally make the copier continue to use for a period of time. If it doesn't work, just replace the separation claw with a new one.

02
Paper path sensor failure

The paper path sensor is mostly located in the separation area, the paper outlet of the fuser, etc., and uses ultrasonic or photoelectric components to detect whether the paper passes or not. If the sensor fails, the passing of the paper cannot be detected. When the paper is advancing, when it touches the small lever transported by the sensor, the ultrasonic wave or light is blocked, so that it is detected that the paper has passed, and an instruction to proceed to the next step is issued. If the small lever fails to rotate, it will prevent the paper from advancing, resulting in a paper jam, so check whether the paper path sensor works correctly.

03
The alignment roller is worn and the drive clutch is damaged

The alignment roller is a hard rubber roller that drives the paper forward for alignment after the copier rolls out the paper, and is located on the upper and lower sides of the paper. After the registration roller is worn, the paper advance speed will be slowed down, and the paper will often get stuck in the middle of the paper path. The drive clutch of the alignment roller is damaged so that the roller cannot rotate and the paper cannot pass through. If this happens, replace the alignment roller with a new one or deal with it accordingly.

04
Exit baffle displacement

The copy paper is output through the exit baffle, and a copy process is completed. For copiers that have been used for a long time, the outlet baffles sometimes shift or deflect, which prevents the smooth output of copy paper and causes paper jams. At this time, the exit baffle should be calibrated to make the baffle straight and move freely, and the paper jam fault will be resolved.

05
Fixer pollution

The fixing roller is the driving roller when the copy paper passes through. The toner melted by the high temperature during fixing is easy to pollute the surface of the fixing roller (especially when the lubrication is poor and the cleaning is not good), so that the copy paper sticks to the fixing roller. At this time, check whether the roller is clean, whether the cleaning blade is intact, whether the silicone oil is replenished, and whether the cleaning paper of the fixing roller is used up. If the fixing roller is dirty, clean it with absolute alcohol, and apply a little silicone oil on the surface. In severe cases, the felt pad or cleaning paper should be replaced.


8 Tips for Avoiding Copier Jams

1. Selection of copiers

The quality of copy paper is the chief culprit of paper jams and service life of copiers. It is best not to use paper with the following phenomena:
a. The same package of paper has uneven thickness, different sizes, and even defects.
b. There is stubble on the edge of the paper.
c. There are too many paper hairs, and a layer of white flakes will be left after shaking on a clean table. Copy paper with too much fluff will cause the pickup roller to be too slippery, so that the paper cannot be picked up, and the wear of the photosensitive drum and fixing roller will be accelerated.

2. Use the nearest carton

The closer the paper is to the photosensitive drum, the shorter the distance it travels during the copying process, and the less chance of "paper jam".


 3. Use the carton evenly

If the two cartons are next to each other, they can be used alternately to avoid paper jams caused by excessive wear and tear of the pickup system of one paper path.


 4. Shake the paper
Shake the paper on a clean table and rub it repeatedly to reduce paper fuzz.


5. Moisture-proof and anti-static

The damp paper is deformed after being heated in the copier, causing "paper jam", which is especially serious when double-sided copying. The weather in autumn and winter is dry, which is prone to static electricity. Two or three sheets of copy paper are often stuck together, causing "paper jams". It is recommended to place a humidifier near the copier.


6. Cleaning

If the "paper jam" phenomenon that the copy paper cannot be picked up often occurs, you can use a piece of wet absorbent cotton (do not dip too much water) to wipe the paper pickup wheel.


7. Edge elimination

When copying originals with a darker background, it often causes the copies to be stuck in the paper outlet of the copier in a fan shape. Using the edge erasing function of the copier can reduce the probability of "paper jam".


8. Regular maintenance

Comprehensive cleaning and maintenance of copiers is the most effective means to ensure copying effect and reduce "paper jam".
