2.2.6 ORIGINAL TRANSPORT AND EXIT
Single-Sided Originals
The feed motor feeds the separated original to the skew correction roller [A] at maximum speed. After skew correction, the feed and transport motors feed the original through the scanning area at a lower speed (the scanning area contains the original exposure guide [B] and DF exposure glass [C]). After scanning, the original is fed out by the transport roller [D] and exit roller [E].
Double-Sided Originals
After skew correction, the ADF feed and transport motors drive the skew correction roller [A], registration roller [B], transport roller [C] and the exit roller [D]. The front side of the original is then scanned.
When the original exit sensor [E] detects the leading edge of the original, the junction gate solenoid is activated and the junction gate [F] opens. The original is then transported 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 [F] is closed. When the original has been fed onto the inverter table, the ADF inverter motor switches on. The original is then fed by the inverter roller [G], and then by the skew correction roller [A] and registration roller [B] to the scanning area (where the reverse side will be scanned).
Basic Operation
The original is then sent to the inverter table [H] again to be turned over. This is done so that the duplex copies will be properly stacked front side down in the exit tray [I] 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 set 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.
