Couple of things that I’ve observed. It’s a combo of shit design and poor human behavior.

-the ones in an office setting take an absolute fuck ton of abuse from people who can’t reload paper or replace an ink cartridge; I have seen punching and slamming on the regular -as a corollary to the above, no one fucking trains workers on copiers. The workers have to figure it out on their own. Violence is a natural response. -as a secondary corollary to the above, you can absolutely fuck with hated colleagues by removing their names from the user list simply by using the manual keypad (or changing the name from TooBeeSan to TooBeeNasty) -the ones in a home setting are persnicketty about color toner and are shit at Bluetooth connections (and thus also take a fuck ton of abuse)
