This idea relates to a sensor for detecting missed stripping of paper from an imaging drum in an automatic xerographic copying apparatus. It is proposed that the dicorotron be used for precleaning and also be used to detect sheets of paper which are missed by the stripping mechanism, In addition to discharging residual toner, the dicorotron detects sheets of paper missed by the stripper mechanism. Detection is by noting the change in current between the dicorotron shield and the plate when the unstripped paper passes under it.
