Take out all the assemblies from the drawer (registration, 2nd BTR, vacuum transport, fuser, decurler and inverter). Release the duplex tensioner and rotate all the duplex shafts to see where the worn is (if). Also take out the registration/transport motor (behind the machine, in the right of the main motor) to check the gears on it.
Well was asked to buy a duplex motor and 2nd btr roller i did .
Well the roller was because the prints were coming out dirty and the old one wasnt cleaning well
Now asked to buy a duplex upper chute assembly, to assist with the paper jams. this unit is quite costly, i hope it fixes it. cause we are able to print duplex then after a few hundred sheets we get a jam. when you try to rotate the duplex belt it is very tight, not sure if that is normal. it sometimes so tight wont rotate in one direction and very hard to do so in other direction.
Really need some help please
Jam is appearing from all trays,
I'll try to get a video so you guys can hear the little grinding sound that occurs and will try to get a pic of the gear that we think is causing it.
If the jams appear just from duplex and from trays 1-3, could be also from the registration/transport motor 007K98040. In that assembly there is a small gear that could be broken and did not have part number.
An update we replaced all the gears, the problem still existed there was a very loud griding noise to the front left of the machine
We cleaned out that area well removed the gear and rollers and it is now duplicating there's still a bit of a grindign sound it seems to be coming from the registration gear region we took a look at one the gears and it seems to have worn down, strange because that was replaced like a month and half ago, seems at if the top part is running against somethin gor used to be running while the machine was jamming cause of the error with the duplexer
Anyway thanks for all the help and suggestion we'll continue working again on machine
Ok thanks, we'll try the motor and see and let you know. Hoping to get oen in soon
At least better to have it so even if don't need it at least it's there.
What fault code?
