Abstract
A sheet removing device for use in an electrophotographic copying machine which removes unstripped sheets from the photosensitive body by providing feed rollers which rotate in reverse upon a stripping failure to pull the sheet off the photosensitive body by acting on the trailing edge portion of the sheet.
Claims3
In an electrophotographic copying machine wherein a developed latent image is produced on a photosensitive body and transferred to a copy sheet which is thereafter stripped from the photosensitive body for further processing, a sheet removing device comprising:
- a reversible feed roll pair adapted to feed sheets to the photosensitive body for transferring a developed latent image thereto;
- detector means for detecting a failure in stripping a sheet off the photosensitive body, and
- control means actuated by said detector means to reverse said feed roll pair to pull the mis-stripped sheet backward off the photosensitive body.
