Very interesting in general, and I just bought a Brother MFC-L8905CDW.
Have you encountered any of those yet?

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 tend to buy the industrial stuff, but at their lower end, because
the extra expense is worth it for better quality.

Sometimes the industrial stuff is cheaper as well.  Like for instance
metro wire shelves.

And one of my selection criteria was weight, with heavier preferred
(meaning more metal and less plastic).

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 customers 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. 

The color was never all that good to be sure, but it was good enough
for me.  Nor did I clean the belt all that often.

  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.

It worked well for many years, but it developed problems as it became
elderly.  In all cases, the underlying problem was that some rubber or
plastic component had aged and become glazed.  Disassembly and
cleaning with a fiberglass brush followed by ethanol wiping helped a
lot.  The famed "Stable 32" error was fixed by a carefully placed
piece of mylar tape that prevented sticking.

But finally it all had worn out too much, and the common wear-out
parts could no longer be purchased anywhere.  And while toner was
still available, the large-capacity cartridges were not, which I took
as an omen.

And after 15 years, it owed me nothing, and many things were greatly
improved over those years.  The new printer is twice as fast as the
old printer, and the color is far better.  And does not misfeed when
humidity is low.
