usual problem, rotten sponge roller, and/or broken upper swing guide on the side
for the roller, with a little skill you can adapt a roller af03-2090/2094, or others (only the rubber though)

+ try to avoid stapling in SEF mode, I have one customer with a machine in difficult enviroment that's acting up even with modded rollers because there's too much "paper rolling". Paper rolls against runnind direction wich is pretty bad for how the stapling/aligning mechanism is designed. Unfortunately the customer need both LEF/SEF stuff staples in his workflow. We ended up installing tray heaters and actually haven't got a call again (so far).
