Bizhub 363 Jam from tray 1 (Cant get one page fed)

[solidzdawg]

Working on another Techs territory while he is out on leave.

BH 363- has 900k on it.

Customer called for jamming---I arrived and saw both PFs for tray 1 & 2 are hammered (200k+)

Replaced tires and cleaned up both, tray 2 feeds fine (sometimes sounds like it struggles) while tray 1 Makes a LOUD Grinding kind of Rubbing friction noise and jams either under Regroller, or before paper exit entrance above fuser (jams in fuser)

EDIT: Tray 2 will intermittently jam, and dog ear copies..There is a mod to install guides on the PF and also the frame, but that doesnt solve why tray 1 is jamming. Ordered Transport Motor, Timing bearings, and worst case: The whold damn right side door assy. GRRRR. Any help would be great

Jam codes :Predominately 3001-1101-

Never seen this before,

Any Suggestions would be a big help, thanks all

Have you cleaned and oiled one-way clutches? =^..^=

[solidzdawg]

No oil but i usually do my scotch pad to rough up the shafts after removing the one ways... Ive never oiled them, I usually replace one ways if their a high Feed Unit count..

So oil does NOT cause One ways to be more prone to slip? Good to know Blackcat

could a bad one way cause super loud rubbing/grinding noise when trying to engage to feed a page? Now im curious george over here lol.


Help a newbie out, im still new to the biz, and could use any help

Check the bushings on the reg unit. They get all bound up from toner residue & and oval out over time. Either clean or replace if ovaled. It will cause noise and jamming.

Yeah, I've seen worn out registration roller bushings at 700K. It causes the rollers to separate at the rear. Early symptoms are paper skew, then jamming. =^..^=

The feed clutches on these machines are pretty light and don't last. They get what looks like rust inside them. Replace them and this should fix it.
Hope this helps.

with 900k I would not even hesitate to replace the shafts. feed rollers. clutch (feed clutch on end) and the 2 black clutches that ride on the shafts. these are easy to take out. I do the whole set up on a refurb. scotch brite works. but with that kind of meter. no way. so. that gets the paper feed. how does the fuser look? and yes registration bearings. it will save you time and future calls when you replace those wear items at the same time

Hello, I know its and old thread, but I have a bizhub 363 with similar issue, paper jams before entering the fuser. I've repaired several printers, but have issue with this one.By any means I'm not an authorized technician, but have good tech level. But have trouble troubleshooting the problem on this particular issue. And one more thing as i'm not very familiar with printers specific part names, could you guys help me a little. I've removed the registration unit from the right door and cleaned everything but paper jam still occurs.

You are talking about replacing the bushings of the rollers. Which roller is the reg roller, i'm little confused, and and when you mentioned PFU do you mean paper feed unit and is it specific for every tray, because with my machine the jam occurred from every tray. Also when the door is pushed a little tighter to the printer, the jam stops.

Any advice will be much appreciated.


Edit: JUst to be on the save side by bushing you mean this right:
