Printer jams occur when the paper feeding through the printer goes awry.
Sometimes the printer ignores the problem, soldiers onward, and extrudes a crumpled mess into the output tray; on other occasions, the printer stops in midjob, and the crumpled mess—or part of it—remains trapped somewhere inside the machine.
When a paper jam occurs, some printers flash lights at you and scream for help. Others sense where the jam is and provide guidance on clearing the blockage. If your printer offers diagnostic advice, follow it. Also, take time to check the printer's documentation for help in clearing jams. Here are the basic steps you'll follow to correct the problem:
- Turn off the printer. If you're going to be working inside the printer, you don't want any trouble with electricity or moving parts. And if you're dealing with a laser printer, you also don't want the fuser to generate additional heat. If the paper is jammed in or near the fuser unit (you'll feel the heat as you come near it), you'll have to wait for the fuser to cool off before clearing the jam.
- Open all doors leading to the paper path. If you can't tell which door leads to the paper jam, start by removing or opening the input tray and following the paper path all the way to the output tray, opening every door or panel that you can find along the way.
- Carefully pull out paper sheets and scraps. Check for paper sheets that are stuck or askew, as well as for paper scraps. Pull paper out of the path firmly but very carefully and slowly. When possible, pull paper in the direction it is supposed to go in under normal conditions—not backward, which could strain the printer's mechanics.Take care to remove all of the paper: Any scraps that remain could cause further jamming. If you have the misfortune of breaking a mechanical piece in the printer, stop what you're doing and call for service or tech support.
- Close all doors and turn on the printer. Once switched on, the printer should reset itself automatically. If the printer reports that it is still jammed, double-check for stray paper scraps, and then close all the doors again. If the printer continues to complain, try turning it off and then back on. If the complaints continue, you'll have to call for service—and hope that a deep-seated piece of paper—rather than a broken mechanical part is the source of the problem.
