MX-FNX4  OPERATIONAL DESCRIPTION  5 – 26
B. Checking for a jam in saddle stitch unit (MX-FNX4)
The saddle stitch unit identifies any of the following conditions as a jam, and sends the jam signal to the host machine. In response, the host
machine may stop copying operation and indicate the presence of a jam on its control panel.
When all the doors are closed after the user has removed the jam, the saddle stitch unit checks whether the vertical path paper sensor
(FSVPPD) has detected the presence of paper. If the sensor has detected paper, the unit will identify the condition as being faulty jam removal
and send the jam signal to the host machine once again.

Inlet delay
FSPIND
The saddle inlet sensor (FSPIND) does not detect paper sheet even if 
predetermined time (distance) has passed after receiving saddle delivery request 
signal from the finisher.
1793
Inlet stationary
FSPIND
The sheet does not move past from the saddle inlet sensor (FSPIND) even if 
predetermined number of sheets have been delivered by the feeder motor (FSFM) 
after the saddle inlet sensor (FSPIND) detects the top edge of sheet.
17A3
Feed delay
FS1PD
The NO.1 paper sensor (FS1PD) does not detect paper sheet even if 
predetermined time (distance) has passed after the saddle inlet sensor (FSPIND) 
detects the top edge of sheet.
1791
Feed stationary
FS1PD, FS2PD, FS3PD
The sheet does not move past from the No.1 paper sensor (FS1PD), No.2 paper 
sensor (FS2PD), and the No.3 paper sensor (FS3PD) even if predetermined 
number of sheets have been delivered by the feed motor (FSFM) after the 
No.1paper sensor (FS1PD) detects the top edge of sheet.
17A1
Delivery delay
FSPDD
The paper sensor (FSPDD) does not detect paper even if predetermined number of 
sheet stacks have been delivered by the paper folding motor (FSFOM) after paper 
is pushed by the paper pushing plate.
1792
Delivery stationary
FSPDD, FSVPPD
The paper stack does not move past from the delivery sensor (FSPDD) even if 
predetermined number of stacks have been delivered by the paper folding motor 
(FSFOM) after the delivery sensor (FSPDD) detects the top edge of sheet. The 
paper stack does not move past from the vertical path paper sensor (FSVPPD) 
even if predetermined number of stacks have been delivered by the paper folding 
motor (FSFOM) after the delivery sensor (FSPDD) detects the stacks.
17A2
Stitcher stapler
FSSHP2, FSSHP1
When the stitcher motor (FSFSTM/FSRSTM) is rotating clockwise, the stitcher 
home position sensor (FSSHP2/FSSHP1) does not turn ON within 0.4 secs after it 
has turned OFF. In addition, the sensor turns ON within 0.4 secs after the motor has 
been rotated counterclockwise.

(FSVPPD), delivery sensor (FSPDD), paper positioning plate paper sensor 
(FSPPPD), saddle inlet sensor (FSPIND) detects a sheet when power is supplied.
1787
Door open
FSINDD, FFDD
The inlet cover sensor (FSINDD) detects opening of the cover during operation. 
The front cover open/close sensor (FFDD) detects opening of the cover while paper 
is on the stapling tray.

C. Checking for a jam in punch module (MX-PNX2A/B/C/D)
The finisher judges to be jammed, and sends the jam signal to the host machine when the conditions shown below occur. Then, the host
machine may stop copy operation, as well as displays paper jam sign.
