Counterpoint: I also used to fix Lexmark printers as a field tech servicing pharmacies. It was routine to see Lexmark MS711dn printers with page counts in the millions. They did not need more than basic maintenance.
The other guy was probably working on ones that didn't get the basic maintenance. People always skimp on preventative care and then are surprised when things break.
When I worked in a computer lab 20ish years ago, being consistent about which side of the paper we loaded when we loaded paper made a huge difference. They are always stacked on the pallet the same way and had a little indicator on the flap of the wrapper around the ream that pointed down.
I'm always surprised when schools want people to donate reams of paper, instead of just ordering a pallet of paper, swapping between a bunch of different weights and qualities is going to cause more way more costs in repairs than just ordering paper by the pallet.
Elimination of most printers and restrictions on the use of remaining ones was one of the cost saving measures put in place to offset the cost of issuing Chromebooks system wide. Others include getting rid of physical text books and elimination of most classroom computers. Classroom computers remain when needed for specific curriculum. For instance my daughter”s architectural drawing classes had computers for running Autocad and Revit.
It was in a pretty dusty environment too, in the weighbridge office at a fruit juice plant.
