Automatic checkout procedure for an electrophotographic copier machine.

摘要

An automatic checkout procedure for an electrophotographic machine where maintenance personnel perform a special entry procedure after which the machine sequences through several different jobs with a variety of selected features and subsystems producing copies for each feature or subsystem tested in order to check for proper operation. In that manner, those features and subsystems which are beginning to operate in a degraded manner can be identified. Specific features and subsystems tested include the document feed, collator, duplex, alternate paper bin, separate, reduction, paper feed, edge erase lamp, interimage erase lamp, shutters, corona voltage and developer bias voltage subsystems.
