How to diagnose and solve a paper jam?

Laser printer (Paper) jam
Every time after launching a print job, your paper jams, there are holes in it, or the paper leaves the printer torn or crumpled.

STEP 1 Check for a paper jam in the printer  

If you notice paper shreds or a paper jam, the cause is likely to be the paper.  

STEP 2 Remove the paper chip(s).  

Try using both hands against the direction of printing to remove the paper. If you cannot remove all of the remaining scraps, turn off the printer and follow the instructions in the manual (on the manufacturer's website).

STEP 3 Replace the paper

If your paper still does not come out of the printer completely after removing all the paper shreds, take the bottom sheet from the pack of paper and try again. If even this sheet comes out of the printer damaged, the entire pack is lost and it is best to use another one.

Check the room temperature before opening a new pack of printer paper. Moisture can cause paper to expand and/or take an uneven shape. In turn, air conditioning or too warm an environment can cause paper to shrink and become more brittle, or several sheets to stick together.  

So you better store your paper in an environment at constant room temperature, such as in a drawer with a flat bottom that you can slide on. Leave the printing paper in its original packaging, usually with a protective wax layer, and take only the sheets you need. Then seal the package with tape.
