I have two MP 1100s in the same location both with close to 6 mil. Everything been running great but now they are both dog earing the copies AFTER the fuser. The dog ears are not flat folded. I have cleaned the upper guide plates with the fingers and the fusers are recently PM'd. Even turned paper over too.
It is intermittent but will tend to get worse as the machines run until it eventually jams randomly in one of these locations 21-28 (between fuser exit and finisher entrance). Note: The customer does not duplex....just one-sided reports...a lot of them! Only runs 8.5 x 11.
I found that the pin on the drive shaft for the transport section (drives the heat pipe area and transport to duplex) is worn badly and have those ordered.
My question is does anyone have any additional advice? I was thinking that with them pushing 6 mil perhaps that the fuser exit guide plate could be part of the issue. But if that were the case the dog ears would be flat folded by the heat pipe roller, right??...these are just slightly bent up on the non-op side. Usually two to three inches in length.
Any feedback welcome.
