SCANNER FAILURE message at power up.DESCRIPTION: SOLUTION ID:
120309
SOLUTION:
CAUSE: A loss of 24V DC at CN63-1 of the scanner driver board due to an open ICP1.
SOLUTION: Verify the operation of L1 (exposure lamp). To verify the operation of L1, perform the
following:
1. Access the 47 mode (power the copier ON, while simultaneously holding the 4 and 7 keys),
output code 00.
2. L1 should power ON.
3. If L1 does not go ON, perform the following:
a. Remove the platen glass.
b. Remove Scanner driver board cover.
c. Locate ICP1 (next to CN60).
d. Set multimeter to 200V DC.
e. With the black lead to frame ground, put the red lead to either leg of ICP1 and check for 24V
DC.
f. If voltage is present, check the other leg of ICP1.
g. If voltage is missing on either side of ICP1, replace the scanner driver board (p/n
26NA-9052).
Note: If the machine has an IP controller or a FAX kit installed, a SCANNER FAILURE message
will occur. If the IP and FAX kit are disconnected from the machine F41-1 code will be indicated.
Verify all 24V DC loads to frame ground, and check for any broken or pinched wires.

F52-1 shortly after pressing the START key.DESCRIPTION: SOLUTION ID:
99802
SOLUTION:
CAUSE: The optical unit fixing cooling fan (FM3) has failed, resulting in no fan rotation.
SOLUTION: To check the operation of the optical unit fixing cooling fan (FM3), perform the
following:
1. Power the copier OFF.
2. Remove the upper right side panel (p/n 26NA-1260) and the ozone filter (p/n 26NA10170),
which will allow unrestricted observation of the optical unit fixing cooling fan. Also, remove the
upper rear reading cover (p/n 26NA12230), which will allow access to the optical unit fixing cooling
fan connector (CN912).
3. Access 47 multimode (power the copier ON, while pressing the 4 and 7 keys). Input code 42,
press *01.
4. Press the START key, the optical unit fixing cooling fan should rotate. If the optical unit fixing
cooling fan fails to rotate, check the control signal at CN912-1 of the optical unit fixing cooling fan
connector. Using a voltmeter (200V DC range), a reading of 24V DC should be observed.
a. Besure to measure the 24V DC as the same time START/PRINT is pressed. The 24V DC
