CHAPTER 10 PAPER DECK
E. Opening/Closing the Deck (compartment)
1. Deck Opening/Closing Movement
When the deck open switch (SW100) is pushed, the deck open solenoid (SL102) turns on to
release the deck (compartment), causing the deck to move to the front by the force of a spring. At
the same time, the deck lifter motor (M101) starts to rotate, and the lifter inside the deck will start
to move down.
When the deck (compartment) is pushed into the copier, the deck open sensor (PS109) detects
the light-blocking plate of the compartment, causing the lifter to move as far up as the pickup
position. When the deck lifter motor rotates in response to deck opening/closing movement, the
deck open indicator (LED100) on the open switch PCB will turn on or flash.
