It's a TB that address this problem on TSC website.
The boss (P/N B0651145) may not be seated correctly in the gear dent (P/N - AB012315) causing the drive to the drum unit to slip, resulting in blurry copies, varying registration and/or paper jams.
There are two primary causes.
1. The boss will slip due to its improper
position.
2. The screw may loosen, which will allow the
boss protrusions to move out of the gear
dents.

Solution

NOTE: Lower the transfer belt unit and remove
the drum assembly to prevent drum
damage.
1. Remove the rear cover.
2. Swing the controller board assembly out of the
way.
3. Remove the flywheel.
4. Remove the boss securing screw.
5. Reposition the drum drive shaft by turning it
counterclockwise (as viewed from rear) until the
three dents in the gear line up with the three
protrusions on the boss.
6. Reseat the boss (which is keyed to the shaft) until it seats into the three dents of the gear and is flush
with the end of the drive shaft.
7. Replace the boss securing screw, flywheel, controller board assembly, rear cover, drum assembly, and raise the transfer belt unit.


Hope this will help you to fix your problem. It's not a rule but apparently only the machines from the first mass production were affected by this problems (assembled improperly in the factory).[IMG]file:///C:/Users/Bogdan/AppData/Local/Temp/moz-screenshot.png[/IMG][IMG]file:///C:/Users/Bogdan/AppData/Local/Temp/moz-screenshot-1.png[/IMG]
