Abstract

Referring to the drawing figures, a non-vacuum copy sheet motion sensor/jam detector 5 for a copying or printing machine is proposed. Detector 5 uses a star wheel 7 rotatably mounted by bearing 8 on the outside of the stationary sleeve-like housing 9 for the drive shaft 10 to the lower output roll 11 of copy sheet feed roll pair 11, 12. Roll pair 11, 12 are part of the copy sheet transport path which brings one copy sheet 13 at a time from the machine paper supply tray 16 forward into transfer relation with the machine photoreceptor where the developed image is transferred from the machine photoreceptor to the copy sheet. The image bearing copy sheet is thereafter fed to the machine fuser where the toner imaged is fixed. Thereafter, the finished copy sheet is discharged from the fuser to a suitable output such as a copy sheet stacker.
