The problem
I printed this sheet with a Xerox laser printer and those streaks appear all over the sheet in various colors and inconsistent, the Xerox is VersaLink C8000
Cause and analysis
An imaging cylinder (drum) or transfer roller nearing the end of its service life is partially transferring toner onto the sheets, generating variable colored streaks that change position as the component wears during printing
The roller cleaning system (cleaning blade) is worn or clogged with toner residue, causing irregular transfer that varies in intensity across successive sheets
Solution proposed by GPX
A possible cause is that the drum or transfer roller have exceeded the service life declared by the machine's page counter, resulting in defective and variable toner transfer
