HP Laserjet 2100 Printer

This printer has a history of suddenly deciding that the Multipurpose tray (the one that pulls down from the front of the printer) is to be used as a manual feed tray. After printing a job, the printer will set and flash its light until you press the Go button. It will then pull from the front tray no matter where you told it to print from. I've see it do this even when the config page (printed by pressing both the Go and Job Cancel buttons at the same time while the printer is ready) clearly shows that MANUAL FEED is OFF. The solution is to cold reset the printer to factory defaults.

To cold reset the printer to the factory defaults turn it off, and then hold down the "Job Cancel" key (the small one) for 10 seconds while turning the printer back on.

To reset the printer to the preset defaults turn it off, and then hold down the "Go" key (the Big one) for 10 seconds while turning the printer back on.
