Re: Help. Konica Minolta Bizhub C759 double/ghost prints on 11x17 only.

Hello Everyone,

We have a Konica Minolta Bizhub C759 and having a problems with the print outs, with red/magenta shadows double/ghost prints. The problems only appears when we print on a 11x17" size paper but for a 8x11" the prints are good. You can print one at a time and they will all look good. But print like 10 or more and the first few will look good and then the rest will start to double/ghost. Please see below for sample prints:

The KM Bizhub C759: 2 years old
Total Counter: 86,730
The fusing unit is new
the 3 imaging units and drum are new CMYK

Did perform the Image Stabilization Only, Image + Stabilization, Print Skew Reset, and Color Registration Adjust but to no avail.

I appreciate the help.

Hi,
I had a similar problem with the C458 e, I replaced the print head and the problem was solved.

Does anyone have any solution for this?
I replace almost all part of C759 machine but still confuse what is the reason for this.
MFP board, Transfer belt, idc, supply board...

Are your guys trained/experienced on the Bizhubs?
1. Remove the Transfer Belt Unit and clean the two color registration sensors properly.
2. Make sure to use only OEM Toner!
