Hi! What lubricant should I use for a copier machine? For the plastic bushings of metal rollers, and for the various rubber paper rollers. I hear some recommend white grease, some recommend silicone oil.
Second question: Inside the unit are four plastic gears that are prone to collect toner/developer which cake and get them stuck. It's low temperature and low speed (30 rpm). What do you recommend to coat these gears?
