[5] OPERATIONAL DESCRIPTIONS
1. Lift Operation
When the power to the main unit is turned ON with the tray at a
midway position (that is, a position where both the upper limit sensor [LUD] and lower limit sensor [LDD] are OFF) or with the tray at
the lower limit position (where the lower limit sensor LDD is ON),
the main unit issues a lift-up request and, in response, the lift motor
is turned ON to lift the tray.
If the Paper-on-tray sensor (LPED) turns ON within 800 encoder
pulses of the start of tray lift, the lift motor is temporarily turned OFF
to stop the tray, and then the paper feed solenoid is turned ON to
lower the pick roller. Subsequently, the lift motor is turned ON, and
the tray is lifted to and stopped at a position where the upper limit
sensor (LUD) is turned ON.
If the Paper-on-tray sensor (LPED) does NOT turn ON within 800
pulses of the start of tray lift, the paper feed solenoid is turned ON
with the lift motor remaining ON, and the pick roller is lowered. The
lift motor stops when the tray reaches a position where the upper
limit sensor (LUD) is turned ON, and subsequently the paper feed
solenoid is turned OFF.
Lift operation is not performed if the power to the main unit is turned
ON with the tray at a position where it can feed paper.
When the tray is drawn out, it lowers by its own weight.
Service Manual
2. Paper Feed Operation
Paper feed operation can be performed if the tray is stationary at a
position where it can feed paper (with the upper limit sensor [LUD]
being ON) and there is paper in the tray.
When paper feed takes place, the transport motor (LPFM), the
transport clutch (LTRC), the paper feed clutch (LPFC), and the
paper feed solenoid (LPFS) operate with the following timings:

*1:
Operation stops only if the main unit synchronization signal is output.
When operation is stopped, the ON/OFF timing for each load is delayed by the stoppage time because each timer is suspended during the
stoppage.
To ensure efficient job processing, operation is not stopped under normal conditions.
When the transport clutch (LTRC) turns ON with the transport
motor (LPFM) is ON (rotating), the transport roller starts rotating.
When the paper feed clutch (LPFC) turns ON in this state, the
paper feed and take-up rollers start rotating.
When the paper feed solenoid (LPFS) turns ON, the take-up roller
is pushed down to press paper.

3. Paper-on-tray Detection
The Paper-on-tray sensor (LPED) checks whether there is paper in
the tray when the tray is lifted and stopped at a position where it
can feed paper, as well as during paper feed operation.
Paper feed operation is stopped if the sensor detects no paper in
the tray during paper feed operation.
