Fault code
Possible cause
Fault isolating / repair
13
.
Front staple detection,
activated.
Stapler head short circuit to
chassis ground.
Find what causes the short circuit and
perform appropriate action.
Wires defective. Check that the voltage between TP16 on
the controller PCB and common ground is
less than 0.9 VDC when the stapler head
is in contact with the anvil and greater
than 2.2 VDC when not in contact. Use a
screw driver to connect the stapler head
with the anvil.
Controller PCB defective. If check above is good, replace the
controller PCB.
14
.
Trimmer not
connected.
Model 75 intact.
Cabels not connected.
If a Trimmer is not connected.
Connect the Interface cable and the
Power cord from the Trimmer to the
Model 75.
Wires defective. Check the wires for an open circuit using
a voltmeter. Measure from 6 on connector
J9 to pin 8 on the DIN receptacle.
Measure from 13 on connector J9 to pin 5
on the DIN receptacle.
Trimmer faulty. See technical documentation for Trimmer.
Controller PCB defective. Replace the controller PCB.
15
.
Infeed sensor SEN 5,
activated.
Paper is blocking the sensor.
Sensor misadjusted.
Remove the paper.
Reposition the sensor to obtain the
voltages below.
Sensor defective. Check that the voltage between TP9 on
the controller PCB and common ground is
greater than 2.2 VDC with the sensor
blocked and less than 0.9 VDC with the
sensor unblocked.
Wires defective. Disconnect the sensor connector. Check
the wires for an open circuit using a
voltmeter. Measure on connector J1
between 24A and 24C. And between 24A
and 2A.
Controller PCB defective. If checks above is good, replace the
controller PCB.
16
.
Infeed transport belt
motor MOT 9,
open circuit.
Motor defective. Disconnect the motor connector. Check
the motor for an open circuit using a
voltmeter.
Wires defective. Disconnect the motor connector. Check
the wires for an open circuit using a
voltmeter. Measure from 14 and 7 on
connector J8 to the motor connector.
Controller PCB defective. Replace the controller PCB.
