towards the inverter table.
Soon after the trailing edge of the original passes the exit sensor, the junction gate solenoid
switches off and the junction gate [E] is closed. When the original has been fed onto the
inverter table, the feed motor switches on in reverse. The original is then fed by the inverter
roller [F], and then by the skew correction roller [A] and registration roller [B] to the
scanning area (where the reverse side will be scanned).
The original is then sent to the inverter table again to be turned over. This is done so that
the duplex copies will be properly stacked front side down in the exit tray [G] in the correct
order.
Original Sensor
During one-to-one copying, copy paper is fed to the skew correction roller in advance (while
the original is still being scanned), to increase the copy speed. The original sensor monitors
the stack of originals in the feeder, and detects when the trailing edge of the last page has
been fed in. The main CPU then stops the copier from feeding an unwanted extra sheet of
copy paper.
2.2.6 CONDITIONS FOR JAM DETECTION
Jam Mode Detection Timing
When turning on the machine, the skew correction sensor, registration
sensor or exit sensor detects an original.
When the cover is closed or DF is down, the skew correction sensor,
registration sensor or exit sensor detects an original.
Initial
When the cover is opened or DF is lifted up, the skew correction
sensor, registration sensor or exit sensor detects an original.
