Hello

I have a Dell M5200 Printer which was purchased used. The question I ask is when printing from the tray everything works quietly/normal. When I try printing an envelope through the front feeder it make a popping noise almost as if one of the wheels were stuck. I have taken this printer apart and looked at every moving part. Other than maybe the belt being loose I see no problem. If this was the case I would think it would make the noise all of the time. Thank you in advance and any help would be greatly appreciated.  Milan    question@adelphia.net
