Error Code 13 on HP LaserJet Laser Printer - Paper jam

Here's a new article posted on how to clear a paper jam:

If you have a PAPER JAM error message, you have to make sure that any obstuction (paper) is removed.. and that all the sensors are back where they belong. Look for trouble at the input trays (all of them), the back door, and under the toner cartridge.

Most business class machines now give location of the paper jam.. they all start with "13" and the have another number, if your machine reads 13.1, you know it in the front. If you make sure all paper is out, then open the toner door and close it, most errors of this type go away. If not, read the control panel.
