tray rollers mpc3002 (orange) versus mp4000 (green)

Nevertheless, sometimes i need to replace the one way gears and bushings in a paper feed unit (according to a RTB which circulate here on this website) which keeps on jamming even after replacing the rollers and holder...
Perhaps it occurs more often when not placing the original rollers?
They might brake the one way's more easy?

I only use oranges in all models because they work the same and are more economical.

Sorry to "pop in again" about this issue, but today again there were jams in the tray's feed in unit, due to the one way bushings where broken.
A few months ago i put the orange rollers in, in stead of the green original ones!
SO... i realy think you need to be carreful to interchange the rollers;
you can do so, but at a certain point the unit will "crash itself"...

is the print/copy volume high? We have those similar machines with high volumes but never experienced any broken bushings or defective torque limiters.
The usual thing we do is clean/inspect the clutches if rollers are replaced prematurely.

I cant remember the last time I went a Ricoh for jamming that was caused by worn feed rollers.
I replace rollers at the same time as the black drum even then still they look fine.

There was a bulletin that the 85s replaced the 90s for standardization. The 85s are cheaper by a little. Can't say if one last longer, they seem to be about the same.

This feed unit had 500K on it and i am not shure when the rollers where replaced, but they looked like "new"...
We bought this machine secondhand via internet, so i don't know the historie...
It could be normal that the bushins break at 500K ?

If it is jamming in the paper tray itself AND if the jammed paper is somewhat folded at the height of the pick up roller (sep roller in fact), THEN (than?) i replace all the one ways togheter with the rollers and the rollers stopper.

The PF clutch of these models are prone to rust and may result into a PJ. Now if the customer doesn't know how to remove the PJs properly, they might end up simply pulling the paper from the feed units while the Feed and Sep rollers are engaged. Then it might/could break the bushings and the torque limiter. IMO
