Blurring Black Lines On Printed Paper After Copying Large Quantity Problem.

[Omar Faris]

Copier model: KONICA MINOLTA BIZHUB 350.

Status: works well without any problem and the printed paper is clear and good.

Problem : some black lines begin to appear gradually, after copying a large quantity such as more than 250 pages, the more i continue copying the more the black lines become clearer.

Exception : if the machine is not used for about an hour after the problem above, the printed papers becomes again good quality, for copying normal quantity.

Question: why these black lines appear only after large quantity of continuous copying, what causes this problem?

Thanks.

How old is drum and dev. Looks like a grounding issue, or residual charge on the drum.

What count on Drum?
Simply put in new drum, Developer kit and reset the counters and F8.

Thank you guys,

The Drum counter is 214 %, maybe it needs a new drum, it's just that i don't understand why this problem comes out only after large quantity of continues copying, i was hesitant is it a problem of drum or something else.

thank you again all of you.
