Remaining paper detection control

• The remaining paper detection control is performed under any of the following condi-
tions:
"Tray 1/tray 2 is closed in position"
"The up/down control of the paper lift-up plate is completed"
A. Paper near-empty detection
• The paper feed tray1(2) near empty sensor detects a paper near-empty condition of the
tray.
• As paper is consumed, the position of the near empty detection actuator provided at the
lift-up plate drive shaft of the paper feed tray1(2) lift-up motor is raised.
• When the near empty detection actuator is raised to a position at which the paper feed
tray1(2) near empty sensor is blocked, the machine detects a near-empty condition.
• A near-empty condition is detected when the amount of paper still available for use
becomes about 50 ± 30 sheets (about 50 sheets in terms of paper weighing 80 g/m
