Function
Drives the feed belt, and the separation, pick-up, and transport as
far as the 1st transport roller.
Controls the original scanning speed.
Feeds paper out of the ARDF and onto the original exit table.
Controls the rotation of the upper inverter roller that feeds the
original in and out of the upper inverter path.
Controls the rotation of the lower inverter roller that feeds the
original in and out of the lower inverter path.
Raises and lowers the pick-up roller.
Raises and lowers the bottom under the original stack.
Controls the ARDF and communicates with the main copier boards.
Detects paper wider than 191.5 mm (7.5 in.) measured from the
reference point.
Detects paper wider than 230 mm (9.1 in.) measured from the
reference point.
Detects paper wider than 263.5 mm (10.4 in.) measured from the
reference point.
Detects paper wider than 288 mm (11.3 in.) measured from the
reference point.
Detects paper wider than 138 mm (5.4 in.) measured from the
reference point.
Detects whether an original is on the table.
Detects whether the bottom plate is in the down position or not.
Detects whether the feed cover is open or not.
Detects when the original is at the correct position for feeding.
Detects leading and trailing edge of the paper as it enters and
leaves the upper path of the inverter.
Detects paper longer than 318 mm (12.5 in.) on the original table.
Detects paper longer than 291 mm (11.5 in.) on the original table.
Detects paper longer than 240 mm (9.5 in.) on the original table.
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.
