The printer (HP laser printer) is broken, and the fault is to print roll paper. At first I considered the problem of wet or thick paper. After the test, no matter what kind of printing paper is loaded, there is a roll paper phenomenon, so the paper factor is excluded. After putting in the printing paper and experimenting several times, it was found that each time the paper was rolled, the left half of the paper was rolled. Viewed from the paper inlet, the right half of the paper is caught by the roller and the left half cannot be lifted.
Is the friction of the roll paper mechanism uneven? But take out the toner cartridge and observe the roll surface of the roll paper. No problem was found. Observing while observing, and subconsciously looking in from the paper inlet, I found that the right side of the roller was “brighter†than the left side. After repeating the operation of opening the top cover twice, it was found that the light was natural light through the gap. Why is there no light through on the left? Reaching out, it turned out to be blocked by the soft iron piece of pressed paper. After carefully pulling the soft iron piece over the roller, put it in and try, you're done!
Generally speaking, in normal use, the iron sheet pressing the paper will not fall under the roller by itself. HP's heavy iron pressure plate is relatively soft, which may be caused by vibration during the movement.
