Konica Minolt Bizhub C 352 CYAN TROUBLE

[Guest]

Hello guys,

I have been having trouble with my Bizhub C 352. I fixed it like a month ago and then i went on holidays.
The machine was in my workshope. When i came back i found out that the machine was having alot of problems.

When i print with the original IU, it prints the blue color all over the page and when i change the IU the blue or cyan simply
dissappears.

When i turn my machine on, after warmimg up it gives me 2 codes.

P 6 and few seconds later P 21.

Now i have tried to change my IU and Print head and even the assembly belt but i failed with everything i tried.

I would really appreciate some help here.


Please forgive my english, it isnt really my strong point.

Hope to hear from the masters soon.

Hi there!
It can be a bad MFP-Board, but my first thinking is to check the contactsprings of the high-voltage-unit.
If they are not 100% in the correct position you get the phenomens you described.

Hello,
Thanks alot for your fast reply.

another fact that i forget to mention was that.
Last time when i fixed the machine it was working fine, then i left for my holidays and during that time it was extremely
cold and temperatures went upto -5. So is it possible that low temperatures might have damaged something?


i am going to try the things you mentioned right now and will inform you as soon as i have tried it.

what does MFP stands for? sorry we have different names in german

Hello,

Thanks alot for your tips my friend it worked finally

Ok here is what my problem was.

I fixed the machine but when i returned from my holidays, the machine was printing alot of cyan all over the page, thn i changed my
IU and the problem changed, it was printing no blue at all and after the warm up phase it was showing me P-6 and P-21 codes.

So i replaced IU, Transfer Belt and PRINT Heads but the problem wasnt going away.

So thn i did what you told me to do. I opned HIGH VOLTAGE UNIT and cleaned it and all the contacts with including the springs with clean tissue, put it back together.
after that i took all the cables out from MFP board (which i know as a mechanica control board) and i put them slowly and carefully back inside.

Turned the machine on and it was working.

So thanks alot for your help.
