M281fdw white blotches print quality issues, drums seem fine?

[Barnamos]

Hey there, I hear that the imaging drum can cause this issue and now each cartridge has a drum? I pulled every one out and rotated to check it but they all seem ok. Since it blotches on all colors and across the entire page does this tell me anything?? All cartridges are HP 202x. Thanks much. 

2 different print qual pages

Hi Barnamos,

If those blotches occur only one time across a whole page, this would point to a damaged ITB (intermediate transfer belt).

If they are repetitive in a single page, that would point to a damaged fuser unit.

If you can post an image of a single whole page, I could tell you exactly which part to have a look at.

They are always in the same section of a page, but slightly different each time. Here's an entire page.

To me this looks like that the fuser assembly film is damaged and will need to be replaced.

Better to replace the whole fuser unit.
