BizHub C554 paper jam at fuser exit

[printprocc]

Recently replaced the fuser unit due to degraded heat roller. Dropped in new fuser and the machine ran fine for roughly 100 clicks (letter size) then jammed at the fuser exit. Several attempts using different weight and size paper have all failed. The paper seems fine within the fuser and the image is fused properly, it just wont transfer to the next section for completion. Not getting an error code either. It seems as though the transfer section isn't being actuated but I can't really be sure.

Sorry if I missed it, what's the actual jam code?

The jam code leads to a sensor that leads to clutches and motors. Will save yourself a lot of time by using the troubleshooting techniques available.

Check the gray roller in the unit at the top of the side door isnt tight to turn - it destroys the clutch that drives it (inside the fusing drive unit)

You may also notice iron oxide accumulation dropping out of this clutch, visible on the fusing drive disengagement finger at the rear side of the second transfer door.

The bushings are a regular point of lubrication on all machines of this engine style, along with the registration bushings.

Fortunately the clutch is easy to change in the 554 without having to remove the fusing drive unit.

Paper will be accordion jamming at fuser exit when this is the issue.

Hi everyone,
Sorry it took so long to reply, it's been a busy week so far. Thank you for the input regarding my problem alas I have not found anything wrong yet. As was suggested by EarthKmTech I checked the gray roller and that whole mechanism and it all seems to turn fine nor do I see any iron oxide deposits anywhere. As mentioned before, I am NOT getting anything more than a paper jam indicator on the display (area 11)and the paper is accordion folded within the fuser exit area. The lead edge of the paper stops right at the point where the transfer section should be grabbing it and moving it thru but it is not.
I'm going to poke around in there a bit more and see if I can find anything but another point in the right direction would be appreciated.

Figured I would try to attach pictures...if this helps.

It’s either clutch8 or the print control board. Had both these parts cause this issue at various times.

Since nobody turned jam codes on to display the code, please go into service mode, counter and look at the jam history.
This is key to properly helping you.

Check the registration rollers and bushings. Had a couple jamming in the fuser. Turned out to be the bushings.
