Ir 3300 is showing white (erasing) streaks

[Andyboachie]

Hello,
I'm about to work on an IR3300, with white erasing streaks that has just started at the left vertical side of the copy. There is enough toner. Apart from the drum, does anybody has another suggestions?
Thanks

Thanks for the response. But as I said, a suggestion of the drum as the problem should be ruled out. I have replaced the whole drum unit, but the erasure still continues.
I have changed the toner unit also.
What happens is: the left side of the copy erases. As more copies are tried, on A4R layout, one or two of the copies might appear rotated across the height of the sheet, as if it was copied on A4 layout.

I don’t see any samples. If you’ve replaced all that then you may have a laser problem. Have you checked to see if the laser glass was clean? If you’re getting that rotation the laser may need to be replaced.

my bet is toner clumps in the Dev unit... but without EXAMPLES no one can be sure .
