Electrophotographic copier including copy sheet detach detector.

摘要

A detach detector for detecting whether or not a copy sheet has been stripped from a photoconductor (19) after transfer comprises a discharge lamp (40) and an electrostatic probe (41). In operation, the lamp discharges the photoconductor during correct operations of the machine to provide a low voltage level at the probe. If, however, a copy sheet remains attached to the photoconductor, the rear side remains at a high voltage level which is detected by the probe.
