Original LaserWriter refurbishment

[ScutBoy]

I have an original LaserWriter (well, actually a LaserWriter Plus) that needs some help. Seems like the pickup mechanism has turned to goo. When powered on, it tries to pick up a sheet for the self-test page, but there just ends up being amber goo on the top sheet, and - thankfully - it doesn't get sucked any further into the machine.

I need to go find a service manual, I guess, to see how major the surgery is to take this guy apart, and figure out if there are reasonable replacement parts (or hacks) available to fix this and anything else I find.

If anyone has been down this road before and can offer any tips or encouragement, please feel free to chime in!

I have a service manual for LaserWriter/Plus.   It from 1989, and it is about one inch thick of 81/2 by ll sheets.

I found the pickup rollars new in service package.  970_1011  They look brand new, but they are sticky to the touch.  I wonder if you could coat them to stop them from deteriorating.

Dont these use Canon or Lexmark mechanisms? if so maybe you can cross-type parts from there as well.

They simply deteriorate with age and as far as I am aware, no you cant really protect it unless you want to seal it in a vacuum.

The original series LaserWriter uses a Canon marking engine.

Canon CX engine to be exact. This earlier thread has links to various service material:
