Changes from the Previous Machine
•Antistatic Control
Metal cover [A] for antistatic control has been added to the following sensors:
•Paper Feed Sensor
•Transport Sensor
•Paper End Sensor
When replacing the those sensors, this cover will also be used after replacement, so remove it from the
old sensors. When you do so, be careful not to deform or damage anything.
1: Paper Feed Sensor
2: Upper Limit Sensor
3: Paper End Sensor
4: Transport Sensor
•Dehumidification Heater
An optional dehumidification heater (attached to the side of the tray) is available.

Mechanism
Paper Feed Separating Mechanism
The tray unit and paper feed transport unit are integrated. The pick-up roller, feed roller and reverse
roller are common with the main frame’s paper feed unit. Both paper feed and paper separation
mechanisms use the same RF paper feed system.
In order to feed the paper at regular intervals, there is a paper feed sensor between the pick-up roller
and the feed roller, and this sensor is used to adjust the paper feed timing.
1. The paper feed motor (M2) turns ON, and feeds the first sheet of paper.
2. To prevent the next sheet from being transported, the pick-up solenoid (SOL1) turns ON just before
the trailing edge of the first sheet passes through the pick-up roller, and the pick-up roller leaves
the paper surface.
3. Just before the trailing edge of the first sheet leaves the paper feed roller, the paper feed motor
(M2) turns OFF.
However, at this time, if the paper feed sensor (S1) does not detect paper (the second sheet is not
transported to the paper feed sensor position), the paper feed motor (M2) does not turn OFF. Pre-
feed is performed as follows:
1. The pick-up solenoid (SOL1) turns OFF, and the second sheet of paper is transported to the
paper feed sensor position.
2. When the trailing edge of the second sheet passes the feed roller, the paper feed motor (M2)
is turned OFF. The pick-up solenoid (SOL1) remains OFF.
4. Just before the trailing edge of the first sheet passes the feed roller, the pick-up solenoid (SOL1)
turns OFF. The pick-up roller is brought into contact with the paper surface.
If paper is pre-fed, the pick-up solenoid (SOL1) will remain OFF, and this operation will not
performed.
5. When the first sheet is transported a specified distance by the downstream transport roller, the
paper feed motor (M2) turns ON to feed the second sheet.

Drive Mechanism
The pick-up roller and feed roller are driven by the paper feed motor (M2). The transport roller is driven
by the transport motor (M1). The friction roller is not driven.
Tray Lift/Descent Mechanism
The tray lift motor (M3) is coupled with the lift shaft, so that when the shaft rotates, the tray bottom plate
rises.
Conditions for tray lift
•The main power is turned ON.
•During copying, the upper limit sensor (S4) is ON (the sensor is not blocked)
•The top cover is closed and the upper limit sensor (S4) is ON.
•The main machine recovers from low power mode.
•The tray lifts until the upper limit sensor (S4) turns OFF (the sensor is blocked).
