Mechanism

1. AF Original Set Mechanism

When the original are set along the original guide fences and the leading edge against the original stopper
gate, the AF original detection sensor turns ON (receives light) and the Master/Print indication on the operation
panel changes to "Master-Making". The thermal-pressure motor then turns ON to lower the TPH until the
TPH pressure sensor goes ON.
After a preset interval, the AF read pulse motor activates in the clockwise direction to bring down the pickup
roller and raises the original stopper gate up. (During this movement, the one-way clutch equipped between
the registration roller gear and its shaft prevents the registration-roller from rotating.)
As the pickup roller comes down, the original stripper roller also comes down, and the both rollers rotates in
the feed direction to advance the original. The leading edge of the original then hits the actuator of the AF
registration sensor and switches the sensor ON (the actuator blocks the sensor) and continues to advance
until it is stopped by the registration roller which is still not driven. The AF registration sensor, after turning
ON, activates the AF read pulse motor in the counterclockwise direction to rotate the registration roller, read
roller and original-ejection-gear to advance the original further forward. The feeding the of the original ends
when the original has moved a total of 100 mm from the original stopper gate.
