HP Color LaserJet 3500, 3550, and 3700 Series Printers - Paper Jams Alternating Between Front and Back Door Issue Description Customers may see paper jams error messages with no paper seen in the paper path. The message will alternate between check the front door and the back door. Workaround The release lever engagement tabs on the rear door can be bumped into the in-correct position. The purpose for this tab is to re-engage the fuser release levers as the rear door is closed. When one or both of these are left in the in-correct position the printer goes into a cycle of alternating between a "Jam in the Front Door" message and "Jam in the Rear Door" message. There is no paper present in the paper path when this happens. When a customer gets the "Jam in the Front Door" message and opens the front door, no paper is found. After the customer closes the front door, they get the "Jam in the Rear Door" message. When they open the rear door, find not paper (even pull out the fuser), and close the rear door, they get the "Jam in the Front Door" message. This cycle will continue
Placing both engagement tabs in the "Correct" position solves the problem and allows the print job to continue.for as long as the customer is willing to keep checking.
