Di-650 / Konica 7165 paper Jam

[Guest]

We are having problems with paper jaming in the ADU.
They are getting and intermitent jam. I mean, pherhaps the machine does 70 copies and it jams and next jam wil came after 20 copies, an so on.The error code is J93-01.The Jam occurs at the sponge roller (Decurl roller) Perhaps we misted cleaning something?

there are two one way bearing/gears on the front of the fuser that wear and start slipping that will cause duplex problems. you can run one sided copies all day with no trouble, but when you do duplex-it jams. replace the gears(2 different ones)be sure to check the small bearings that all the shafts ride on while you are in there.
