Remaining paper detection control

• The remaining amount of paper is detected by the position of the remaining paper detection gear [6] moved
together with the shaft [5] of the paper lift motor (M100) which drives the paper lift plate.
• The remaining paper detection gear incorporates the actuator [9], and the actuator position is detected by
the four remaining paper sensors; /1 (PS102) [1], /2 (PS103) [2], /3 (PS104) [3], and /4 (PS105) [4].
• According to on/off statuses of the four sensors, the remaining amount of paper can be figured out.
