2.4.2 Indicating the Level of Paper on the Deck Front Cover
0009-2055
The drive of the deck lifter motor (M102) is received by a coupling, and is then transmitted to the rack through a
drive belt. The rack is equipped with a black belt, moving up and down within the display window in the deck front
cover in keeping with the movement of the rack.
When the level of paper descreases and, as a result, the lifter moves to pickup position, the area of the black belt
within the display window increases, while the area of white (indicating the amount of paper) decreases, enabling a
check on the level of paper.
