B. Shutter operation
If the No.1 tray passes the delivery slot while any paper stack is
present on the No.1 tray, stacked paper may be caught by the
delivery slot. The delivery slot is equipped with the shutter to pre-
vent such a trouble. When the No.1 tray passes the delivery slot,
the shutter is closed. This operation is implemented even if no
paper is stacked on the tray.
When the delivery motor (FAM) is rotated while the shutter open/
close clutch (FSHC) and the delivery lower roller clutch (FAORC)
are on, the shutter is raised (closed) and lowered (opened, delivery
is enabled) when the motor runs reverse. Opening and closing of
the shutter is detected by the shutter home position sensor
(FSHTD).
