Abstract: In order to test components of a xerographic copier, the copier is run through test cycles in each of which copying stations which act directly on the imaging element are set to abnormal conditions. In one such cycle, during a first period, the exposure lamp is initially on and then turned off. In a further period in the same cycle, erase lamps are selectively turned on and off to produce a test pattern image. Other components which are either turned off at selected periods in a copying cycle or driven with lower than normal voltages include the charging, transfer and cleaning corotrons. In addition the developer bias may be set low. The resulting copy sheets provides an indication of fault conditions within the copier.

Abstract: A document copier machine with an automatic document feeder (ADF) combined with a semiautomatic document feeder (SADF) is operated according to a job recovery procedure in which multiple originals may need recopying in order to replace copies destroyed when a jam occurs. The procedure calls for feeding the required number of originals needed for recopy through the SADF and once the jam recovery is complete, automatic restarting of the ADF occurs in order to complete the job interrupted by the jam.
