HL-3170CDW Print Issue

Dec 20, 2021
My Brother HL-3170CDW misses a line of print on every page printed as shown in the attached pdf. I have pulled the black drum & toner cartridge out and cleaned the drum as shown on the Brother site:

Black or coloured vertical lines or streaks on printed pages

This has not made any improvement. The line in the pdf is so consistent and identically reproduceable it seems to me that it may be an issue with the printer's control hardware or firmware. I'd expect to see a similar but not identical error in printing after a few attampts at cleaning.

Any help on this issue would be much appreciated.
