Can I connect a laser printer or office multi-function fax/printer to my UPS?
It is not recommended to use these appliances on a UPS. Laser printers have a large heating and sealing component that can draw up to 1000 watts and multi-function fax/printers draw a huge amount of surge current during start-up. Therefore you must have a greater VA rated UPS to do the same job which makes the UPS backup very uneconomical.
