Hp laserjet 2420dn
ANSWER : I would suspect the fixing film has wear. You can prove the theory by doing a half-stop test. This stops the print before it enters the fixing film assembly. Load paper in the drop down MF tray in the front. Send a print job and when the tail end starts to enter, open the cartridge lid on top to stop it.
