Hello,
Laser printers shouldn’t be plugged into an UPS because they have high power demands, including peak power draw during warm-up or printing, which can overload the UPS, especially those with non-sinewave models. This can lead to the UPS shutting down, voiding the warranty, and potentially damaging both the UPS and the printer.
I’m sure it is drawing more than 4 amps when you actually print something.
