      Why you shouldn’t connect a printer to a UPS

      (Unless you accurately size the UPS for peak power requirements)

      When turned on, Laser printers draw a high current to heat up their fuser roller. A typical UPS cannot cope with such a spike.

      Descriptions of the problem by UPS manufacturers do not go into details.

      The problem may be one or other of

      The initial inrush current at start-up, This can be seven or more times the average operating current of the printer.
      Initial power-on when the fuser is heated to the temperature needed to fuse toner. Subsequent re-heating of the fuser may be periodic or may occur when the printer switches from and idle state to full-power to satisfy a print request after a period of inactivity.
      Fuser temperature is up to 200 °C (392 °F).
