Sir there is a lever in the rear of the machine when you lift the document feeder it is not jam or broke, also there is a small magnet and sensor in the front of the Doc feeder right side and the copier it self ensure the document feeder is properly aligned. Does this happen on the document feeder or on the big glass? Also mite want to have a technician run alignment & tray adjustment.
Btw, I’m available to help over the phone in case u need at
