No. Component Function
S15 Skew Correction Sensor After pick-up and separation, the skew correction s ensor
detects the leading edge of the original. This signal slows
the rotation of the entrance roller for a prescribed number of
pulses to buckle the original and correct skew.
S16 Separation Sensor Detects the separation of the original.
S17 Exit Sensor Detects the leading and trailing edges of paper feed out to
the original table and detects misfeeds. Also signals when
to stop the scanning belt.
S18 Registration Sensor Detects the leading edge and trailing edges of the original to
detects jams and stops the original at the ADF exposure
glass to correct buckle.
S19 Pick-up Roller HP Sensor Detects whether the pick-up roller is up or not.
S20 Lower inverter sensor Detects the original in the path of the lower inverter before it
feeds to the inverter rollers for 2nd side scanning, or feeds
to the exit rollers for exit.
S21 ARDF Position Sensor Detects whether the ARDF unit is up or down for scanning
on the main exposure glass (book mode).
S22 APS Start Sensor Signals the CPU when the DF is opened and closed (for
platen mode) so that the original size sensors in the copier
can check the original size.
SOLENOIDS
SOL01 Upper Inverter Solenoid Opens and closes the upper junction gate at the entrance of
the upper inverter path. During simplex scanning, closes the
upper inverter path so the original exits straight to the exit
tray. During duplex scanning, opens to allow the original to
enter the upper inverter path and closes to direct it once
again into the feed path for 2nd side scanning.
SOL02 Lower Inverter Solenoid Opens and closes the lower junction gate . During duplex
scanning opens after the 2nd side is scanned to direct the
original into the lower inverter path while the next sheet is
fed to the upper inverter path above, then closes to direct
the original out onto the original exit tray.
