1. Operation
a.
Non-sort, sort, and group modes
According to the FNS operation signal from the
main body, M703 (tray up/down) elevates the
main tray until PS702 (tray upper limit) responds
(ON).
When PS706 (main tray paper exit) detects the
paper, M703 lowers the tray. When the signal
from PS702 has changed to OFF, and a pre-
defined time period has elapsed, M703 raises
the tray again. M703 stops with PS702 signal
ON.
b. Staple mode
When M707 (paper exit roller) has started rotat-
ing and a predefined time period has elapsed,
M703 (tray up/down) lowers the main tray. The
rotation of M703 is reversed to raise the main
tray when PS706 (main tray paper exit) detects
the trailing edge of the paper stack on the tray.
M703 stops when the signal from PS707 (stapler
paper exit upper limit) changes from ON to OFF.
