It quite and old printer, and easy enough in the 4050 to get to the Tray 2 Paper Pick-Up roller; but no service manual for the 4000/4050TN's
I really just need to know how to peel the right front lower HP LJ panel for tray 2 and tray 3 off. If you could include a picture with that , it would be great.

The printer is jamming with new pick up rollers, and even sounds like a mushy felt on the solenoids.
