MX-FN11 OPERATIONAL DESCRIPTION 4 – 2
2. Feed/drive system
A. Outline
The finisher is designed to operate according to the commands
from its host machine to deliver arriving copies to trays in the
appropriate mode: simple stacking, job offset, or stapling.
Four delivery modes are available.
from its host machine to deliver arriving copies to trays in the
appropriate mode: simple stacking, job offset, or stapling.
Four delivery modes are available.
B. Control configuration of finisher
The finisher moves copies arriving from the host machine to the
delivery tray, stapling tray, according to the mode of delivery. On
the stapling tray, the copies are subjected to job offset or stapling
as instructed by the host machine.
In addition, stack is delivered from the stapling tray with the help of
the trailing edge assist guide as well as the delivery roller. The inlet
motor (FFM), delivery motor (FAM), and the trailing edge assist
motor (FASM) are the stepping motors. These motors are con-
trolled by the microprocessor (CPU) on the finisher controller PCB,
and rotate either clockwise or counterclockwise.
The paper paths are equipped with the following two sensors for
detection of paper (arrival, passage):
• Inlet sensor (FED)
• Feed path sensor (FPDD)
In addition, each delivery tray is equipped with a sensor designed
to detect the presence/absence of paper on it.
• No.1 tray paper sensor (FBED1)
• No.2 tray paper sensor (FBED2)
If a copy fails to reach or move past each sensor within a specific
period of time, the finisher controller PCB identifies the condition as
a jam, and stops the ongoing operation, and at the same time,
informs the host machine of the condition. When all doors are
closed after the paper jam is removed, the above two sensors (inlet
sensor and delivery path sensor) check whether or not copies are
being detected. If the sensors detect a copy, the finisher unit judges
that paper jams have not completely been removed, and sends the
paper jam removal signal to the host machine again.
