Tray 1 release mechanism
When tray 1 is selected for staple mode,
tray 1 must be moved down to the lower
paper exit. However, to move past the
sensors at the lower exit, the tray must be
moved away from the finisher.
To do this, the tray 1 shift motor turns until
the cut-out in the gear disk enters the tray
release sensor [A]. At this time, the arm
[B] has reached position [C], and is
pushing against the plate [D], in towards
the finisher. However, the plate is fixed, so
the tray moves out away from the finisher.
Then, the tray 1 shift motor stops, then the
tray 1 lift motor lowers tray 1.
When the tray 1 lower limit sensor is
activated (as described on the previous
page), the tray has moved past the
sensors at the lower exit. The tray 1 shift
motor turns on again until the gear disk
activates the tray shift sensor [E]. This
moves the tray back against the finisher.
Next, tray 1 lifts until the finisher detects
that the tray is at the correct height.
