Squeaking noise when printing
Probably, but you?re going to have to try to isolate the problem a little better. Typically this would involve removing side panels and such; however, you may just have a faulty consumable like a toner cartridge, fuser or more likely the transfer kit. I typically try to isolate the sounds location then try replacing some of the consumables in that area one by one. In your case if you can?t isolate the location I would start with the transfer kit since that has a greater chance of making noise.
