18.7 About Original Jams and ADF Errors
18.7.1 Type of jam
(1) Feed unit jam : Original has not arrived at aligning sensor during pre-feeding
Original has not arrived during feed of 1st original in 2in1 feed
Original is retained at aligning sensor during feed in regular mode
(2) Transport jam : Original has not arrived at the exit sensor(exit inversion sensor)during
discharge
Original has not arrived at the exit sensor(exit inversion sensor)during
dual-side feed
(3) Exit jam : Original is retained at the exit sensor(exit inversion sensor)during dis-
charge
Original is retained at the exit sensor(exit inversion sensor)during dual-
side feed
(4) Two-original(2in1)jam in : Original has not arrived at aligning sensor during feed of 2nd original
in feed unit 2in1 feed
