CHAPTER 8 PAPER DECK
1.5 Opening/Closing the Compartment
1.5.1 Opening/Closing the Compartment
When the deck open switch (SW100) is pushed, the deck open solenoid (SL102) turns on
to release the compartment, which is then pushed forward several centimeters to the front by
the force of a spring. At the same time, the deck lifter motor (M102) starts to rotate, and the
lifter inside the deck starts to move down.
When the compartment is slid inside the deck by hand, on the other hand, the deck open
sensor (PS109) detects the light-blocking plate of the compartment, and the lifter is let to
move up to pickup position.
When the deck lifter motor rotates for opening or closing the deck, the deck open indica-
tor (LED100) located on the open switch PCB remains on or flashes.
