First, I apologize if this has been asked and answered but here is my problem. I have an HP laserjet 601M which works perfectly until I installed the additional paper tray (Tray 3). The printer recognizes that there is a tray 3 installed. However, every time I try tp print anything, I get a "paper jam in tray 3" error message. There is no jam at all. I cannot see any obvious problems with either the printer or the additional tray. Does anyone else have this problem, or do I have a defective printer and/or paper tray?
Any help or advice would be greatly appreciated.
