B. Operational descriptions
(1) Paper feed operation
a. Preliminary operation before paper feed
1) Set paper in the tray, and insert the tray into the machine. The tray
sensor turns on.
2) The lift-up motor operates to lift the tray.
3) The paper upper limit sensor turns on to stop the tray at the speci-
fied position.
b. Paper feed operation
1) When copy/print operation is started, the motors (MM, FUM, VPM,
and TRM) and the clutch (TRC) are turned on to turn on the sole-
noid (T1PUS) at the timing of paper pickup. This rotates and falls
the take-up roller to pick up paper.
noid (T1PUS) at the timing of paper pickup. This rotates and falls
the take-up roller to pick up paper.
2) At the same time, the paper feed roller rotates to feed paper to the
transport section. At that time, the separation roller rotates to pre-
vent against double feed of paper.
vent against double feed of paper.
(2) Each paper feed tray paper size detection method
a. Paper feed tray 1, 2
The paper feed tray 1 is used exclusively for A4 (11 x 8.5) paper size.
The paper feed tray 2 is used for A4, 11 x 8.5, or B5 paper size.
To change the paper size, change the paper guide and change the set
value of SIM 26-2.
