LEXMARK 4039 10P

I HAVE REPLACED THE D ROLLER ASSEMBLY. THE TORQUE MOTOR JUST MOVES SLIGHTLY BUT NOT ENOUGH TO ENGAGE THE SLIP GEAR. IS THERE ANY ADJUSTMENT OR SPECIFIC GEAR MESHING REQUIRED.
I consider myself an omplete expert on these. I worked on 4039 for 7 years at IBM. The problem sounds like the right rail assembly. When the roller is told to turn by the printer it goes through the frame to the solenoid to rotate the droller. The right rail assemply is very hard to put in but I am certain it is the problem from what you say. If you can take the tray out and rotate the roller freely then you have a right rail problem. If not, it may be the solenoid not picking. Listen for it to click when you send a job to it. If it clicks and the attempts to turn but is stopped by the paper then it is a right rail assempbly. Let me know if I am wrong about the symptoms or how you resolve this.

Very hard to put in is a bit of an understatement. I once got a 4039 that someone had abandoned in the middle of a right rail replacement. My tech buddie, who only works on HPs, took one look at it and the box of loose parts and brought it to me. I had to tear it all apart and put it back together again. After that one, I won't replace any more right rails. It wouldn't have taken much engineering to have designed it so that the right rail just came out the bottom instead of having the whole printer built around it. Somebody has to graduate at the bottom of the engineering class or Lexmark wouldn't have any engineers.

Thank you for your replies.
I still haven't got it working.
Also I can't see a solenoid on this 10P
However I had another 10P in with a burned out PSU.
I fitted the PSU from the first machine (The one that wont pick up.This machine now has the same pick up fault.Is it possible that the pick up fault is caused by a missing voltage?
