C1.04,C2.04,and C3.04
NOTE: Roll x means Roll 1,2, or 3.
The Media Drive Motor (MOT1, BSD 7.1) was
trying to feed the Roll x Media forward to the
registration position but the Media Registration
Sensor (A21Q1, BSD 8.1) failed to sense the
media.
Initial Actions
• Check the Media Roil (in the Drawer that
was in use when the fault occurred).
Roll1 : BSD 7.2
Roll 2: BSD 7.3
Roll 3: BSD 7.4
• Check that the Drive Chain, PL 7.2, is OK
(BSD 7.1).
Procedure
Enter DIAGNOSTICS (General Procedures).
Enter [0703] (ROLL FEED MOTOR FOR-
WARD) and observe the Media Drive Motor.
The Media Drive Motor runs.
Y N
Check that the 3 Media Drawers are
closed. Check the operation of the
Drawer Reed Switches as follows:
Enter [0713] for Drawer 1
Enter [0714] for Drawer 2
Enter [0715] for Drawer 3
Each Drawer Reed switch functions
correctly.
Y N
A B
Refer to BSD 7.1 and check the circuit
of the Drawer Reed Switch that does
not function correctly. Check that the
actuating magnet is not missing.
A B
Refer to BSD 7.1, NOTE 2, and check the
resistances of the windings of the Media
Drive Motor (MOT1)
The resistances of the windings of the
Media Drive Motor (MOT1) are OK.
Y N
I Replace the Media Drive Motor
(MOT1),PL7.2.
Refer to BSD 7.1, NOTE 1, and check the
voltages at A7P1.
The voltages at A7P1 are OK.
Y N
I
Check all wiring between A2P208 and
A7P1. If the wiring is OK, replace the
Driver PWB(A2), PL 1.1
NOTE: Drive Motor PWBs (A24), BSD
8.1, and (A7) are Identical and can be
exchanged with each other.
Replace the Drive Motor PWB (A7), PL
7.2.
Refer to BSD 8.1. Enter [0917] and then enter
[1] on the keypad. Observe the Transport
Drive Motor (A21M0T1).
The Transport Drive Motor (A21M0T1)
runs.
Y N
Refer to BSD 8.1, NOTE 4, and check the
resistances of the windings of the
Transport Drive Motor (A21M0T1).
The resistances of the windings of the
Transport Drive Motor (A21MOT1) are
OK.
Y N
Replace the Transport Drive Motor
(A21MOT1),PL8.1.
Refer to BSD 8.1, NOTE 2, and check the
voltages at A24P1.
The voltages at A24P1 are OK.
Y N
D E
C D E
Check all wiring between A2P210 and
A24P1. If the wiring is OK, replace
the Driver PWB (A2),PL1.1.
NOTE: Drive Motor PWBs (A24) and
(A7), BSD 7.1, are identical and can be
exchanged with each other.
Replace the Drive Motor PWB (A24), PL
7.2.
Refer to BSD 8.1. Enter [0803] and check the
Media Registration Sensor.
The Media Registration Sensor is OK.
Y N
Check the circuit of the Media Registration
Sensor (A21Q1).
Check for mechanical binding or broken parts
in the area of the Registration Drive Rolls and
Pinch Rolls.
