Bizhup PRO C6500 White line in cyan

[drodas78]

Hi friends.

Attached is the picture with the problem I'm getting from the cyan color. The picture is a pattern at 128. I want to have some advice or instructions before getting into it. Please let me know what do you think I need to check for.

Thank you for your help.

[drodas78]

Hi.

I hope not to bother you. I don't know all the terms and processes yet.

Would you explain me more?
- How I enter into 36 mode process adjustment?
- "Initialization on cyan unit all steps" is a part of 36 mode process adjustment?

Thank you very much.

What direction did that print come out at? Is that an A3/DLT? Or A4/Letter?
Also, what paper are we talking (type and weight)?

[drodas78]

The direction is from right to left it came out of the printer in the same way that is the scan. It's a Letter. The lines appear no matter the paper.

Okay, so if I understood you correctly, the feed direction was this:

So, since you only got that on cyan, I would check the cyan charge corona, the cyan developing unit and the cyan drum, in that order.

check your cyan dv unit, it looks like a something on the mag roller.

Dust tends to build up in there. Poor design if you ask me. You can clean it off or take a can of dust off to it. It should get rid of the other smaller ones too if this is what is causing it.

Otherwise looks like something on the mag roller to me, too.

You are right that's the feed direction.

It looks like fluff in dev unit, try inserting a bit of paper between the blade and roller and work it towards the back of the unit. You might be able to work it out.

A hair in the laser path under the potential sensor will give a sharp line.... But a hair or speck closer to the laser window gives a more unfocused White line like above.

For those who mentioned dirty charge corona.... That would give a dark line

[drodas78]

So do I have to check for hair or speck closer to the image unit window? Can you send me a pic of where to insert the bit of paper?

Thanks.

I agree...dev mag roller contaminant. Might be fuzz or a hardened piece of developer caught up in the mag/doctor blade.
