Why ups clicks when startup laser printer?
I suspect your laser printer is plugged into the UPS as well as your other computer equipment. Most personal type UPS’s aren’t designed to handle the power draw of a laser printer (really only designed for computers) and shouldn’t be used for them, only the large commercial size ones can adequately handle the power needs. Inkjet printers and computers are fine, but not laser printers. Why it clicks is due to the power draw a laser printer requires when it starts up and the UPS is unable to match the output required (due to the limited wiring and circuitry within the unit itself, not the wall supplied power the UPS is plugged into) and it’s circuits read a voltage drop of the unit and switch over to battery power to try and compensate, which doesn’t really work that well since the power from the battery isn’t any better to drive a laser printer than it was otherwise. If your laser printer is not connected to the UPS, then your issue is with the wall supplied power electrical system and
