c652 tray 3 jams

**EarthKmTech** · 03-13-2012

c452 series tray 4 feed assembly is compatible with the c451 series too for anyone distressed at the fact that only the individual parts are listed in the c451 parts manual.

have done it a few times, never had an issue.

Hi Emujo,

Would you have a part nr. for that p/u roller. Cheers. I want to give it a try.

Hi all,

Had similar issue on Bizhub 552 today, ordered and replaced the tray 3 feed assy as it was indeed out of date per bulletins. No difference. Paper from tray 3 only would skew and crumple, sometimes jam. Tore apart and inspected/cleaned the "level conveyance section" and right side door. No difference. Took out tray 2 to watch paper pass from tray 3, was skewing in "level conveyance section".

Further observed paper lifting in tray 3. Looked higher at the rear lead edge. Took out paper (maybe 100 sheets) inspected lifting of tray 3, looked fine. Putting paper back in I noticed 10 dog eared sheets at bottom of pile, looked fine in tray but was lifting the paper just enough at the rear lead edge to catch and skew going through the p/u feed assy.

Sadly I normally check the paper first but it really looked fine in the tray, I even fanned it and didn't see the dog eared sheets.

Issue resolved for me.

Cheers,

Colin

Good thread, I have had that broken door latch on a couple of machines. Its easy to miss. Also some techs are not using the right tools to remove the feed unit and breaks the plastic housing near the clutches. You cant remove it with your normal screwdriver without removing tray one and two first, only shows a crack but causes the machine to jam.

If you remove the 2 screws from the rail (1 on each side) that prevent the tray from rolling out all the way you can easily get to the rear screw for the feed unit.

Thanks that would make things easier. Did not even occur to me.

Just an FYI, KM has a new ribbed pickup roller for these models. It is for the trays and the bypass tray. The new 654's are coming with it installed. The part# is A5C1562200. There is a tech bulletin for it.
