Paper jams are common on most laser printers. Because Laser printers use heat to fuse the toner from the toner cartridge onto the paper,  they seem to foul up more than inkjet printers in this respect. Type of paper is important, if you experience frequent paper jams, try changing the brand or quality of paper. Paper jams are also common when the paper drawer is almost empty & the printer picks up more than one sheet of paper.

If you find that you have a paper jam, usually the warning light will be flashing & the printer will not accept any further print jobs.

 Here are a few tips:

It is important to remove all jammed pieces of paper with extreme care.
Pulling at sheets may cause pieces of the paper to tear and stay in the printer, causing further jams. Paper is very abrasive and incorrectly removing paper that is in contact with the process unit or drum may damage its surface.
Once the error is cleared, the printer should automatically warm up and resume printing. It may reprint the jammed page, but this will depend on where the jam occurred.
If  jams occur frequently, try cleaning the printer and changing the paper as it may have become damp.  The rule when removing paper jams from laser printers, is to be firm but not rough with the device. Pull the paper out slowly & carefully without snatching it which will cause the paper to tear. It is not the end of the world if you cannot get all the paper out, but in extreme cases further dismantling of the laser printer may be required. Never lose your temper & damage the printer. If the paper jams occur often, there is always a reason for it . try changing the type of paper that you use first & see what happens from there.
