Not everything is designed to run all the way empty.

Running your car at a very low fuel level is hard on the fuel pump - it has to work hard to slurp up what few drops are left - and on many newer models if you actually run it dry the consequences can range from having to re-prime the pump to the pump grenading and sending shrapnel into the injectors, ruining them TOO.

Isn't the interaction between the laser toner cartridge and drum completely electrostatic? I thought the toner just gets pulled out of the cartridge via static electricity?

Yeah but the pump equivalent here is on the toner cartridge IIRC
