No. Component
Function
MOTORS
M01 Feed Motor
Drives the feed belt, and the separation, pick-up, and transport as
far as the 1st transport roller.
M02 Transport Motor
Controls the original scanning speed.
M03 Exit Motor
Feeds paper out of the ARDF and onto the original exit table.
M04 Upper Inverter
Motor
Controls the rotation of the upper inverter roller that feeds the
original in and out of the upper inverter path.
M05 Lower Inverter
Motor
Controls the rotation of the lower inverter roller that feeds the
original in and out of the lower inverter path.
M06 Pick-up Motor
Raises and lowers the pick-up roller.
M07 Bottom Plate Lift
Motor
Raises and lowers the bottom under the original stack.
PCB
PCB01 ARDF Main Board
Controls the ARDF and communicates with the main copier boards.
SENSORS
S01 Original Width
Sensor 2
Detects paper wider than 191.5 mm (7.5 in.) measured from the
reference point.
S02 Original Width
Sensor 3
Detects paper wider than 230 mm (9.1 in.) measured from the
reference point.
S03 Original Width
Sensor 4
Detects paper wider than 263.5 mm (10.4 in.) measured from the
reference point.
S04 Original Width
Sensor 5
Detects paper wider than 288 mm (11.3 in.) measured from the
reference point.
S05 Original Width
Sensor 1
Detects paper wider than 138 mm (5.4 in.) measured from the
reference point.
S06 Original Set
Sensor
Detects whether an original is on the table.
S07 Bottom Plate HP
Sensor
Detects whether the bottom plate is in the down position or not.
S08 Feed Cover
Sensor
Detects whether the feed cover is open or not.
S09 Bottom Plate
Position Sensor
Detects when the original is at the correct position for feeding.
S10 Upper Inverter
Sensor
Detects leading and trailing edge of the paper as it enters and
leaves the upper path of the inverter.
S11 LG Detection
Sensor
Detects paper longer than 318 mm (12.5 in.) on the original table.
S12 A4 Detection
Sensor
Detects paper longer than 291 mm (11.5 in.) on the original table.
S13 B5 Detection
Sensor
Detects paper longer than 240 mm (9.5 in.) on the original table.
S14 Interval Sensor
Adjusts the timing of the original transport speed to the original
scanning speed after the original feeds. During duplex scanning, or
if original is small (B6, A5, or HLT) the interval sensor detects the
leading edge of the original and delays the pre-scanning motor for
the prescribed number of pulses to buckle the original and correct
skew.
