[CQ] Bizhub 223 snake alike patern

[Guest]

I am having some intermittent snake pattern banding about 1 inch wide. Seem like a charge issue. Anyone had that issue? Anyone found a solution?

Well If you have maglev looking like snake you may have dodgy toner. Or damp dev unit. They are not rare this time of season.

I try replacing drum and transfer roller with problem coming back. I did replace the dev unit and put fresh dev mix and problem is finally gone. I am trying to post a sample. Still not sure what was the problem. On the snake pattern I can rub off what feel like dev mix.

Drum arcing. i know this well if there is a small hole in the DEV seal (normaly deep side) the drum would leak to the mag roller. change drum and dev tank or fix seals. Get DS collar kit.
Fong Kong toner?

Well wit THAT information + your scan it would have been much easier to diagnose the problem..........

Arc Marks. Dark bands are charge, light marks are transfer in most cases.

Copier repair 101.

Re: Bizhub 223 snake alike patern

I didn't had a sample with me and customer was closed for the holiday. I still have the dev unit and will inspect for hole in mylar covering the mag roller. Seem like a common problem with these models. Had another 363 with same problem 3 weeks ago, cleaned the charge corona unit but they never called back.

Re: Bizhub 223 snake alike patern

Customer called with same problem again. New drum, new dev unit. I am pulling my hair cause I have no idea what else could it be.

I would put the new drum and dv unit in another machine. If it works in another machine, I would start going backwards into the machine and change the hv power unit.
