Jams intermittently J7220. It goes something like this:
When corner stapling letter, small sets (4 or less) the paper enters the stapling tray and is stapled. The eject belt taps the trail edge then comes around to eject the stack, but stops under the stapling tray. The set is never ejected. Another set stacks in on top of the first. The machine goes into a J7220. The second set is not stapled. No jams in the printer. One page remains at FS5 just entering the stapling tray at the top.
It never happens on larger sets (maybe giving the eject motor M18 some rest time? It never rests on the smaller sets). It may do 400 small sets without a jam. I noticed that the regulating plates may be gripping the set too tightly, buckling up the center of the set. That does not explain why the eject belt does not complete it's circuit though.
The section that feeds the stapling tray was a bit banged up due to the impatience of my enduser at removing jams from that area, but nothing that could not be re-formed back to where it belongs.
I've cleaned the reflective sensors in the stapling tray and in the main tray exit, like the code indicates. but again I don't see how that will help the eject belt drive. I've actually seen it jam twice up close.
The eject belt is intact with it's "foot" firmly attached (I've replaced a few of those), and it's in time, properly ejecting hundreds of sets, just not all of them.
I've considered two things:
1) confirming the registration plate adjustment for paper width,
2) replacing M18. The thing is, it's a beefy pulse motor and I doubt that it's failing.
The machine is at 8M, about 2.5M of those stapled, and has had all its recommended maintenance.
What am I missing? =^..^=
