Only black text are faded

[PhilipN]

My xerox wc 7530 has a problem with black texts. I replaced the cartridge, but no succes. When I print text in colors its fine. It only affects black textes. Black grafics are OK.

When I print text with RGB 0,0,1 the printed text is OK.

Hi,

Try to perform Calibration in Tools Mode. And it will be better to upload here some images with CMYK with 50% coverage of each.

Swap R1 and R4. Or reseat R1. Use cleaning wand under drum (orange tab on machine side) after swap/reseat. 

R1-R4 are underneith your toners

Hi,

Thanks but no result. It happens when I moved the printer from one location to another.

Hi,

Why R1 and R4 ?
I swapped the R1 with R2 but no result.
Used the cleaning thinks.

It happens when I moved the printer from one location to another.
Any other suggestions?
