Ricoh D131 - Paper Height Detection

PAPER HEIGHT DETECTION

2.4 PAPER HEIGHT DETECTION
As paper is consumed from the top of the stack [A], the paper tray rises and the
actuator [B] attached to the tray passes through paper height sensor 3 [C], paper
height sensor 2 [D], and paper height sensor 1 [E] until the actuator reaches the
paper near end sensor [F].
The operation panel displays a message for each paper height until the actuator
reaches the near-end sensor, then a message warns the user that the tray is nearly
empty.
The table summarizes the relation between sensor detection and the number of
sheets remaining in the stack.
