hi, I have a problem on a C8000 I have a gray background on everything I print. I changed the black corona, swap the drum, the head of the writings. but the problem is still present.I have even changed the black development unit, but I still have the gray background in everything I print. Have you some solution for me please? when I'm doing a patterne test 49, I have a band at the level of black only.

Ensure your SCSI cable between the machine and Fiery are correctly seated.
Could be worth changing your black Dev - I've often seen it expire before life and it'll leave a background toning.

'shot gunning' a problem is VERY costly ...
you mention NOTHING about the page counts on machine/supplies.
did you make all proper adjustments after replacing parts
Genuine Toners/Drum?
"head of writings?" you mean Laser Asmy?
Are you a trained tech or end user
do you have a service manual?

Thank you for answering me.
I changed the black developer, I also checked the cable. but I still have the same problem. there is the same black background when I print the test pattern 43 in the technical mode, i have the same black back in all the sheets.
I am a user and i have experience in konica printers. I have the technical manual. of C8000.
the total counter is 2,517,080.
