Not sure if this helps but if you cant pull the unit out it due to a locking flap has brocken part number D686 4358 if set in the incorrect position it will also show cods and a jam.

This is a great help, thanks, this part is actually broken half of it is laying in the botom of the finisher!
However this was most likely broken by me trying the pull the unit out.

In your photo you are describing the older type finishers that sit on a MPC4502/5502 and older as the shift tray was driven by belt.

From the MPC5503 with finisher types SR3140/3150/3160 and 3170 they are gear driven only.

The shift tray has arms on it with a long straight gear which meshes with a circular gear and the drive motor for it is located parallel with the staple unit in its home position at the front of the finisher and not as the rear as shown in your photo

The picture is from an SR4120 from a MP6503, but you are correct on the drive differences.

Yep I agree all the new finishers have the sprung loaded gear just as the 02's had.

Hello again. I hope you can help. I have this issue again & not sure how it happens. I found the client has broken the guide D6864358

My question is how does one replace this part? It is only 2x screws to remove when broken but to replace is very inaccessible to relocate/fit

Hoping someone has a short cut to replacing this little plastic guide.

Item 157 is this pdf.

The paper guide motor moves the gray C-shaped guides that align the paper for stapling. It is a square stepper motor near the top of the finisher. I recently had this error and it was caused by the adhesive between the motor and the mounting plate coming unglued. The simplest solution to this particular problem is to swap the motor mounting screws with the longer cover screws that must be removed to access the motor. The longer screws will thread into the frame of the motor itself and not just the mounting plate. Hope this helps someone.
