TRAY UP/DOWN MECHANISMS
B545 24 SM
Staple mode
In staple mode, stapled stacks can be delivered to either tray, but they can only go
to the lower exit. So, if tray 1 is selected, tray 1 [A] moves down to the lower paper
exit.
Tray 1 lowers until the actuator [B] enters the tray 1 lower limit sensor [C]. Tray 1
then lifts up until lower stack height sensor 1 [D] is activated.
When tray 1 is moved down to the lower exit, tray 2 must be moved down out of
the way. So, tray 2 [E] is also lowered until the tray 2 shunt position sensor [F]
detects tray 2 (or the top of the paper stack in tray 2).
The method of paper height detection is the same as for the upper exit area.
When the tray lowers during printing, the actuator will enter the tray 1 overflow 2
sensor [G]. When this happens, the machine detects that the paper stack height
has exceeded the overflow limit.
