[Jamming] Samsung CLX 6220 jamming 0x2001/0x2003

[foundry]

only 35 k on this machine. Repeated 0x2001 and 0x2003 codes.
Appears most often on multpage runs. Did find inversion solenoid sticking to foam on back plate which I removed.
Not fond of clutch/gear for driving. Is this a common issue?
Has anyone had any experience with lagging sensors?

Any and all help gratefully accepted. I have two of these machines out there and currently they are both giving me grief.

Just in case you might be interested. Problem solved. Once foam backing was removed off of the back of the two feed solenoids (pickup and inversion) because they were sticking the machine ran ok for a couple of weeks. The stop where the foam was was bent up to prevent the clutch plate from contacting the solenoid. The issue is that after a couple of weeks the plate started to develop residual magnetism and as such remained on too long resulting in excessive feed.
The solution was to replace the original foam stop on the solenoid with a hard rubber stop and the problem was solved
