MX-LCX2

Service Manual

 

When the main unit is turned ON, if the tray is at the lower limit
position (lower limit sensor: LDD ON position), the lift motor is
turned ON to lift the tray.
When the paper presence/empty sensor (LPED) is turned ON
within 800 pulses of the encoder signal from start of lifting up the
tray, the lift motor is turned OFF to stop the tray, and the paper feed
solenoid is turned ON to move down the pickup roller. After that,
the lift motor is turned ON to lift the tray. The tray is stopped when
the upper limit sensor (LUD) is turned ON.

If the paper presence/empty sensor (LPED) is not turned on within
800 pulses, the paper feed solenoid is turned ON with the lift motor
ON to move down the pickup roller. The lift motor is stopped at the
upper limit sensor (LUD) ON position, and the paper feed solenoid
is turned OFF.
When the machine power is turned on, if the tray is on the paper
feed position, lifting is not performed.
When the tray is pulled out, it moves down by its own weight.

When the tray is stationary at the paper feed position (upper limit
sensor: LUD ON position) and there is paper on the tray, paper
feed operation can be performed.
Paper feed operation is performed by the transport motor (LPFM),
the transport clutch (LTRC), the paper feed clutch (LPFC), and the
paper feed solenoid (LPFS) at the following timing.

When the transport clutch (LTRC) is turned ON with the transport
motor (LRFM) ON (rotating), the transport roller rotates. When the
paper feed clutch (LPFC) is turned on under this state, the paper
feed roller and the take-up roller rotate. When the paper feed sole-
noid (LPFS) is turned ON, the take-up roller is pushed down to
press paper.
