ricoh mpc4501

[alphablaster]

Hello everyone !! I was wondering if anyone could help me with this : I have a ricoh mpc 4501 and I have blue letters instead of black, this is only on the copying mode either I put the original at the ADF or the glass(I have cleaned the optics). Any ideas of what that might be? Should I change the laser unit ? Thank you in advance !

if printing is fine. Then i would said ccd in optics is problem. I have seen them with nothing on glass get a blue copy come out.

Try doing a memory clear on copier application only

has something happened with the nv-ram of that machine? The machines come from the factory with exact values ​​for scanning, contrast, brightness, color saturation ... Look for the sheet with the factory default values ​​and compare them with those of the machine.

Are you copying in B/W mode or in Auto Color detect. It is not unusual for "Black" ink on paper to appear as dark blue under bright lighting like you get from the exposure lamp. In B/W mode the color PCDU are not used and the color transfer rollers in the ITB do not press the transfer belt against the color drums.

IMHO, Auto Color detection invariably will cause trouble. Set default to B/W.

Reset the white balance "Book settings" in the Scanner SP settings back to the birth certificate.
I assume that you're talking about a blue background all over the page?
I've also seen this where everything comes out pink.

His original post said blue letters instead of black. No blue background.

I don't think so, the machine was working fine, this happened a day after we got it to the client i don't know what happened at the transport.
