Hello, Customer got some labels stuck in the processor. I removed the front cover, drum shaft knob, removed two screws, released toner hopper and two latches released. The unit pulls out about 1/8 inch but thats it. Is there anything else holding it back? I left the customer site and forgot to open the right side door to see if that was the holdup. does that door need to be opened? Any suggestions would be great. thanks

Someone may have left the latch for the cleaning unit in the up position. You may be able to push the front one down with a long flat blade if you can get to it. If it is a 1250P you can go through the top to access the front and rear latches.

My guess is that the drum shaft is seized to the drum bearings. If it were me, I would apply a couple drops of penetrating oil (like Marvel Mystery Oil) to the spot where the drum shaft meets the front bearing. Then I would apply some pulling pressure with my left hand on the image unit, and with my right hand GENTLY tap on the end of the drum shaft with a small hammer. The vibration from the tapping helps the oil penetrate. If you do it right you won't fall on your ass when it comes loose. =^..^=

Thanks Blackest, the machine only has 143k on the machine, could there be caught on a burr or something

if the ADU is pulled out the process unit is locked in place.
close the adu and the process unit will be released.

I tried with the transport section pushed in and pulled out. The lever was definitely released too.

Yank it...

Could be bad advice, make sure the connectors are disconnected.

Found that if one on the flanges from the drum turns slightly skew it binds good.
In your case it moves a bit.

LOL. I didn't even notice the drum screw wasn't removed. Yeah put the handle back on and unscrew the shafts correctly ;)

How did I miss that?!

Yes, just put the handle back on the shaft and unscrew the handle ASSEMBLY from the drum shaft.
I never thought of doing it that way. =^..^=

There were two screws holding the knob on and there was a sleeve that the knob fit over. That was ir

parts 2 3 and 4 are to remain as one piece, simply sharply turn the handle counter clockwise and it will unscrew from the drum shaft
