[Misc] bizhub c351 wrinkling paper

[acsolutions]

Hello, My c351 wrinkles every sheet from LTR,LGL,LTR-R and 11x17 all at the last three inches of the page. pulled the fuser don't see anything wrong. watched the advance knob on the side of the machine to look for hesitation. ( removed side cover to see) no copy quality problems. cleaned and inspected sensors in paper path. There are between 1 and 3 wrinkles about 3/4 of an inch long.

I live in the metric (real? ) world so I don't know what those paper sizes are, but if your talking about long papers, these machines did that out of the box new. Loading of the paper has to be done very carefully and dead straight in the tray with the guides set perfectly and even then you must close the tray gently and slowly as closing it too fast makes everything you just did a total waste of time. I always had more success printing long papers from tray 1 as it seems less fussy.

the problem happens out of every tray does not matter what type of paper it is, long or short. The machine has three trays, does it from all trays!

awesome, lots of info! yeah, tried the fuser loop adjustment for drawers 1 thru 3 I had zeroed everything I think it went +3
+5 and -13 then zero'ed all entries and made no difference. I did not try pushing on the door I'll give that a try!
usually with the loop adj. the wrinkles go all the way through the page, this is the last 3 inches!

Re: bizhub c351 wrinkling paper

What is the condition of Fuser Rollers? If they are worn out due to heavy stock or some special media, it may give this problem. As paper trail edge leves Transfer belt & 2nd transfer roll paper is driven only by fuser.
Hope this may help

Re: bizhub c351 wrinkling paper

You need to replace the fuser drive ass'y due to a wobbly bushing. A pain but not too bad.

There's is a knowledge base with pictures of this problem.(last three inches are wavy)
