Customer says they get fantom paper empty message (tray is loaded) and they get intermittent jams from tray 1. I replaced tray 1 feed rollers and cleaned one way bearings. About 300K and I'm thinking the clutch in back is failing. What puzzles me is the paper empty signal they get. I did clean the empty sensor and actuator is ok. Any thoughts would be welcome. I recently replaced fuser and drum, but don't think that could be related.

Re: BH 222 tray #1 jams-paper empty
I've seen something similar on the 423's. Maybe somebody can confirm if the paper pickup mechanism is the same?
There is a white plastic lever at the back of the feed unit. When that lever is pressed by the back of the tray the pickup tire lowers, and the tray starts to lift. If the metal bracket that holds the pickup roller becomes bent, the paper level can drop too low to feed.
=^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Re: BH 222 tray #1 jams-paper empty
You should replace the one-ways first.
Unless the one-way is completely shot, it's hard to tell by hand if they're bad or not.
And, of course, best cover all bases when the god forsaken feed rollers take 30 minutes to replace.Comment

Re: BH 222 tray #1 jams-paper empty
The white plastic lever is the same from Bizhub 222 - 420 to 423. The lever was redesigned (a new code is available) and there is a kit to reinforce the back of the tray that gets broken when users are playing soccer with paper trays...Comment

Re: BH 222 tray #1 jams-paper empty
Returned today with a known good tray #1 feed assembly. The whole unit. Put it in and ran 200 + copies without jam or error. Customer called later and said jamming at side and false paper empty indicator from tray 1. The jam counter showed 7 jams from my previous visit at the separation area, not from the tray. Is it possible the registration sensor or unit is the problem? I did clean the sensor and tested the actuator - all looked good. I have not replaced the rear pick up clutch yet. Any thoughts would be welcomed.
Thanks!Comment

Replace the registration clutch. I have seen them cause false "paper empty" errors.

Re: BH 222 tray #1 jams-paper empty
I was getting some jams a few weeks ago from tray two, cleaning the one-way bearings for tray two seemed to work. This might explain that too. The jams are not reaching the fuser, so this would definitely seem likely. I just assumed that clutch would cause jams, not the paper empty problem. I have a Bh350 reg. clutch I will try tomorrow. I think they are the same? What about a bad tray? I'm going to check it for cracks tomorrow. Possible pick up clutch? I know these are the modified ones (no grease), so I generally refrain from replacing these unless it's obvious.
Thanks for the help.Comment

Re: BH 222 tray #1 jams-paper empty
Is the customer pulling paper out of the machine???? nothing coming out of the tray? Rear pick up clutch! Just change it. Theses clutches go bad all the time. What are you waiting for?Comment

Excellent. It doesn't take much developer to mess up an electromagnetic clutch. =^..^=If you'd like a serious answer to your request:

Re: BH 222 tray #1 jams-paper empty
Darren - It looks like you were dead on! I replaced registration clutch and have not heard from them in two days. They are a busy law firm and produce loads of copy. There was toner or developer inside the clutch when I removed it. It must have been caused when the dev. tank seal broke and caused some leaking earlier. I'm surprised I have not run into this earlier with all the bad tanks on these series of machines. Thanks for your help!!!!Comment

Re: BH 222 tray #1 jams-paper empty
Why not modifying them with the improved drum spacer collar?I'm surprised I have not run into this earlier with all the bad tanks on these series of machines.
