BH500 vertical lines PRINT ONLY

[GeorgeK]

Appreciate your help.

On a bizhub 500 I have the intermittent vertical lines (as per attachment) only in printouts.
Copies are just fine.

Any suggestions ?

Thanks in advance for your help.

i would check the drum surface, can you print a blank 11x17 or A3 to see if the marks repeat?

Had the exact same thing on a bh 283.
No (obvious)marks on drum but changing the drum resolved the issue.
After 20-30k exactly the same,only guess was that the dev tank was causing it.
Changed the drum again and haven't had a problem since.Weird.
Try to swap a drum from another machine if possible.
