Abstract

Some photocopies exhibit an overtoning during initial (morn-ing) start-updue to decrease in the triboelectric charge Q of the developer during the previous unused period, One proposed remedy is to compensate for a lower Q by initially reducing the photoreceptor charge from its normal value, Less toner would then be attracted to and developed on the charged photo-receptor surface, As the Q of the developer rises due to normal copier activity, the photoreceptor charge could be gradually increased until normal operation levels are reached,
