FujiXerox DocuCentre-III C7600 (Printer cant detect % darkness)

Jump to solution
Product Name: FujiXerox DocuCentre-III C7600
Operating System: Not Applicable

Hi,

I'm having trouble with the machine detecting percentages of Black. K100%, K70% and K50 look exactly like 100% black. This happened after i changed a new drum. However the older drum does not have this issue. Could it be the setting? Anyone have clue for this issue? Thanksr6.jpg

Hi,

It is not from settings. I think it is from the new drum.

HI Gabi,

 

I bought a new drum, replaced. The % darkness is correct now. But however the missing area is back agian with the new drum. could it be the ROS agian? i just printed 50 pages and the missing area is back agian. I have have cleaned 2 times (using the method the video you shown me) but the problem is back afte 50 pages print. Do you know what is wrong with the machine?

Hi,

It could be from the used black developer housing which let the toner to blow towards laser.

You can fix it by replacing the black developer housing together with black developer material.
