Paper feed control

A. Pick-up mechanism
(1) Drive transmission
The driving force of the feed motor (M150) is transmitted to the paper feed gear /3 [4] through various gears. The
paper feed gear /3 is connected with the pick-up solenoid (SD151) [1] through the claw [2]. When SD151 is
turned OFF, the coupling between the paper feed gear /3 and the paper feed coupling gear /B [3] provided on
the front stage is disengaged and the paper feed gear /3 does not rotate. When SD151 turns ON, the claw is
released to engage the paper feed gear /3 to the paper feed coupling gear /B. In this way, the paper feed gear /
3 rotates and the driving force is transmitted to the paper feed roller unit [6] through the paper feed gear [5] to
pick up paper.
