I have a strange paper jam when I print 2-side 130 gr/sqm glossy paper ,100% black, 330x480mm, at least 2 sheets. Initialy the jam code was 0019 but now it is 0014. For 90% black I haven't jams. I tested the primary fixing unit to another printer C8000 and it works fine. I switched the fixing motors and fixing motors drive pcb. I replaced all rolls around primary fixing unit, I switched the optical sensors PS305 and PS307. I replaced black developing unit.
For 300gr/sqm paper I haven't jams.
Please give me a clue.
