Code Description
*: model equipped with DADF-Q1 (outside Japan, iR7105/7095; inside Japan: iR7105/7095/7086).
**: model equipped with DADF-M1 (outside Japan: iR7086).
0001 An open circuit of the counter signal has been detected.
E043 The rotation of the pickup motor of the side paper deck is faulty.
0000 The side paper deck pickup motor has gone on, but the PLL lock signal is not
detected for 2
sec or more (1st detection).
MEMO:
For the 2nd and subsequent detection, the machine will indicate "E043" on the
screen
offering a choice of sources of paper.
E051 The horizontal registration HP detection has an error.
0001 After the start of horizontal registration HP detection, the HP sensor is not off
within 5 sec
(i.e., not leaving home position).
MEMO:
If an error is detected in the course of horizontal registration HP detection at
power-on, the
machine will indicate the presence of a jam.
0002 After the start of horizontal registration HP detection, the home position is not
detected
within 5 sec.
MEMO:
If an error is detected in the course of horizontal registration HP detection at
power-on, the
machine will indicate the presence of a jam.
0003 Replace the horizontal registration HP sensor. Replace the horizontal
registration motor.
Replace the stackless transport driver PCB. Replace the DC controller PCB.
E065 The high-voltage output has a fault. (primary charging assembly)
0000 A fault (leak) is detected when high voltage is supplied to the primary
charging assembly.
E067 The high-voltage output has a fault.
0000 A fault is detected at the same time in 2 of the following: primary high voltage,
pre-transfer
high voltage, transfer high voltage, separation high voltage.
E068 The high-voltage output has a fault. (separation charging assembly)
0000 A fault (leak) has been detected while the separation charging assembly is
being supplied
with high voltage.
E069 The transfer high voltage has an error.
0000 A fault (leak) has been detected while the transfer charging assembly is being
supplied with
high voltage.
E102 A read error has occurred in relation to the laser scanner unit EEPROM data.
0001 The correction data cannot be read from the EEPROM of the laser scanner
unit.
E110 The laser scanner motor rotation has a fault.
0000 After the laser scanner motor has gone on, the PLL lock signal of the motor is
not detected
for 15 sec or more.
E111 The laser scanner motor cooling fan rotation has a fault.
0000 After the laser scanner motor cooling fan has gone on, the fan stop signal is
detected for 5
sec or more.
E121 A fault exists in the rotation of the following: laser scanner unit cooling fan, reader heat
discharge fan 1, reader heat discharge fan 2.
