This 3M copier machine is a vintage item from the 1970s that has been refurbished for use. Powers on ! Bulb works ! the roller is rolling! Cooling fan spins ! Requires special development paper which is first exposed to light source on the top tray for a desired duration of time and then fed into the lower roller to develop with heat . . . Directions on under the lid The Spring tension seems high on the roller heater but I don’t not have paper to test if it’s too tight or not . Looks like one spring was lost and replaced in the past as there are two different sizes on it now Any question feel free to ask Please refer to photos closely No returns thank you !
