Brother HL-4040 print quality

[copyman]

Hi, Don't know this printer that well. Going out to look at it next week and wanted to get some ideas. I'm thinking since the drum was just replaced and didn't help that it might be transfer belt? Wrinkling maybe fuser? Sample they sent me attached.

This was the email that came with sample:

Thanks in advance for any help

Your guessing is right. This may be as simple as printer needs good vacuuming and cleaning, but as T belt is consumable I will take one with me on the site. Overall clean printer, replace belt if counter is due or damaged, check cassette paper guides and make sure they use fresh stack of paper(not damp).
Good luck
