STAPLER MECHANISM
B545 32 SM
4.7.3 FEED OUT AND TRANSPORT
When stapling starts, the exit guide plate motor [A] switches on and opens the exit
guide plate [B], so that the stapled stack can exit to the tray. The exit guide plate
sensor [C] detects when to switch off the exit guide plate motor.
After the prints have been stapled, the stack feed-out motor [D] starts. The pawl [E]
on the stack feed out belt [F] lifts the stapled set and feeds it to the tray [G].
The exit guide plate closes at a specified interval after the stapled prints have
started to feed out. Then the exit roller takes over the stack feed-out. The stack
feed-out motor turns off when the pawl actuates the stack feed-out belt home
position sensor [H].
When tray 1 is passing this area on its way back up to the upper exit, the exit guide
safety switch [I] cuts power to the tray lift motor if the guide is opened too far. This
prevents damage to the user’s fingers if they are inside the lower exit when the tray
is moving up.
