At this time, if the jam status already indicates a jam, the jam status isretained.● Initial Paper Presence Jam during Warm-up RotationWhen the Paper Leading Edge Sensor (PS751) detects absence of paper at the start ofwarm-up rotation and the Fixing Delivery Sensor (PS701) or the Paper Width Sensor (PS702)detects presence of paper, it is judged as an initial paper presence jam.● Paper Absence Detection during CleaningOFFPickup Solenoid (SL1)Paper Leading EdgeSensor (PS751)ONOFFONJam1370msec200msecPaper Detection PeriodWhen the Paper Leading Edge Sensor (PS751) cannot detect presence of paper within 1370msec. after 200 msec. from the start of paper pickup, it is judged as paper absence.F-2-32Service Works■ At parts replacementNo work is required for this product at parts replacement.■ MaintenanceNo periodically replaced parts, durable parts or periodical service is set for this product.■ Notes on service worksNone.
