[stuckmx]

Hi
I cant get past this jam J-3204 while printing on duplex
Printing on simplex works fine just not on duplex

Paper always stuck on the same place (as you can see in the image which is a printed counter)
Can anyone point me in the right direction please?

Try to clean the one way gears from fuser.
Also there are some clutches down below the fusing unit. clean those too.
this should solve your problem.

bro do u happen to know the names?
or by the way how to test the clutches? can they be tested with I/O? do they pshically move?

now it get stuck at ef-101 (j-3204, ef-101 its where the sheet gets stuck, simplex, in duplex mode it gets stuck past the fusing exit and enters vertically adu but never enters adu tray below)

thanks a lot for your help

Thank you Rohullah,

We have checked all is working fine.
Another observation is that, even when we print simplex blank sheet, it still jams with a fold and gives the jam code j-3204.

Your help is very much appreciated.

Thank you

errors j-3102, j-3201 and 3204 is all the same and problem is in FUSING BELT UNIT LOWER. Replacing unit to a NEW will solve problems. I checked this at least twice on my machines and solutions really work instead of changing motors, gears or sensors.
I think that problems in bearings on shafts inside this unit that clogged with toner and dust and rotation speed for main heating roller and lower heating film is little different that produce errors.

From my experience max lifetime of heating unit lw is about 800K clicks so after 2-3 replacement of film you need to buy new unit.
