Code Cause
0003 The horizontal registration detection
movement for the preceding sheet does not end
within 5 sec at the start of a horizontal
registration search during printing.
E065 There is an error in the high-voltage output to the transfer charging assembly.
0000 An error (leakage) is detected in the high-
voltage output to the primary charging
assembly.
E067 There is an error in the high-voltage output.
0000 An error is detected in two or more of the
following at the same time: the primary high
voltage, pre-transfer high voltage, transfer
high voltage, and separation high voltage. Or,
an error (leakage) in the high-voltage output to
the separation charging assembly is detected.
E068 There is an error in the high-voltage output to the separation charging assembly.
0000 An error (leakage) to the high-voltage output
to the separation charging assembly is
detected.
E069 There is an error in the high-voltage output to the transfer charging assembly.
0000 An error (leakage) is detected in the high-
voltage output to the transfer charging
assembly.
E100 The BD PCB is faulty.
0000 The BD signal does not arrive within 1 sec
after the laser drive signal has been generated.
Or, the BD signal does not arrive for 1 sec or
more while the laser remains ON.
E110 The rotation of the laser scanner motor is faulty.
0000 The constant speed rotation signal (LM-RDY)
does not arrive for 20 sec or more after the
laser scanner motor (M4) drive signal has been
generated.
E111 The rotation of the laser motor cooling fan is faulty.
0000 The lock signal arrives for 5 sec or more
although the laser motor cooling fan (FM1) is
being driven.
E121 The rotation of the laser cooling fan (1/2) is faulty.
0001 The lock signal arrives for 5 sec or more
although the laser cooling fan 1 (FM3) is being
driven.
0002 The lock signal arrives for 5 sec or more
although the laser cooling fan 2 (FM5) is being
driven.
E202 There is an error in the detection of the scanner home position.
