I retired from the daily grind just after the CZU fire and Covid.  I
currently don't see many repairs on larger and heavier printers
because I would need to carry the printers up and down 50 stairs to
work on them.  I also don't have the necessary bench space available.
My current customers are mostly home users who normally don't need or
purchase big and heavy business class printers.

I haven't worked on any MFC-L8905CDW printers but have recently
cleaned a similar model after an aftermarket toner cartridge dumped
toner everywhere.  I didn't see anything unusual when I tested it.

The old MFC-9840CDW (discontinued) was not a good printer.

Two of my customer bought them many years ago.  As I vaguely recall,
the colors did not print true, the color self-calibration didn't quite
work, and I had to clean toner from the belt with almost every
cartridge change.  I don't recall any component failures or
replacement.  The rubber parts, which are usually the first to die,
held up well, mostly because the printer was lightly used.
