• Code: E215
• Description: The thermistor has a short circuit.
  • The thermistor of the scanning lamp heater registers 170°C or higher when the fluorescent lamp signal (FLON) is off (including power-on).
• Remedy: 1) Disconnect connector J115 of the reader controller PCB, and measure the resistance between connectors J115-5 (GND) and J115-6 (FL-THE) on the harness side. Is it 10 W or less or 100k W or more? NO: The reader controller PCB is faulty. Go to step 4). YES: Go to step 2). Lamp heater 2) Disconnect connector J2039 of the lamp heater, and measure the resistance between connectors J2039-2 (GND) and J2039-3 (FLTHE) of the lamp heater. Is the resistance 100 W or less or 100k W or more? YES: Replace the lamp heater. Flat cable and connector (poor contact) 3) Are connectors J115 of the reader controller PCB, connectors J2037 and J2035 of the flat cable, and connector J2039 of the lamp heater connected securely? NO: Connect them securely. Reader controller PCB 4) When the machine is turned on, is the voltage between HJ122-1 (GNDU) and J122-2 (+38 V) on the harness side of the connector of the reader controller PCB 38 V? NO: See “The reader unit DC power supply is absent.” YES: Replace the reader controller PCB.

• Code: E216
• Description: The scanning lamp (fluorescent lamp) fails to turn on in 15 sec.
  • The light intensify sensor does not detect light from the scanning lamp in 15 sec.
• Remedy: Scanning lamp (life) 1) Try replacing the scanning lamp. Is the problem corrected? YES: End. Inverter PCB, Reader PCB 2) Try replacing the inverter PCB. Is the problem corrected? YES: End. NO: Replace the reader controller PCB.

• Code: E217
• Description: The scanning lamp heater is out of order.
  • When the scanning lamp heater is controlled to a specific temperature, its temperature does not exceed a specific setting when it has been supplied with power for 3 min or more.
• Remedy: Lamp heater 1) Try replacing the lamp heater. Is the problem corrected? YES: End. NO: Replace the reader controller PCB.

• Code: E219
• Description: • The scanning lamp (fluorescent) has reached the end of its life.
  • The scanning lamp thermistor detects 150°C or higher when the scanning lamp is on.
• Remedy: Scanning lamp (life) 1) Try replacing the scanning lamp. Is the problem corrected? YES: End. Inverter PCB, Reader PCB 2) Try replacing the inverter PCB. Is the problem corrected? YES: End. NO: Replace the reader controller PCB.

• Code: E220
• Description: The scanning lamp (fluorescent) is faulty.
  • The light of the scanning lamp fails to reach a specific level of intensity within 10 sec after it has been turned on.
• Remedy: Scanning lamp 1) Is the scanning lamp mounted correctly? NO: Mount the scanning lamp correctly. (Caution) 2) Try replacing the scanning lamp. Is the problem corrected? YES: Replace the scanning lamp. Inverter PCB 3) Are connectors J1002 and J1003 on the inverter PCB and connector J129 on the reader controller PCB connected securely? NO: Connect the connectors securely. YES: Replace the inverter PCB. Caution: • If you have to remove the scanning lamp and mount it back, be sure to execute the following in service mode: Function>MISC-R>USELAMP. • If you have mounted a new scanning lamp, be sure to execute the following in service mode: Function>MISC-R>LAMP-ADJ for light intensity adjustment and then Function>CCD>CCD-ADJ.

• Code: E400
• Description: The communication with the ADF has an error.
  • No signal is returned by the ADF 1 sec or more after communication with the ADF has started.
• Remedy: Perfrom the work according to the instructions in the service manual of the feeder.

• Code: E401
• Description: • The pickup motor (M1) fails to rotate. • The pickup roller sensor (S5) is faulty.
  • A flag is attached to the spindle of the pickup motor (M1), and the rotation of the motor is monitored with reference to the flag (blocking the pickup roller sensor S5). The pickup roller sensor fails to turn on and off twice or more in within 1 sec.
• Remedy: Perfrom the work according to the instructions in the service manual of the feeder.

• Code: E402
• Description: • The belt motor (M3) fails to rotate. • The belt motor clock senor (S10) is faulty.
  • The number of feeder motor clock puleses within 200 msec is below a specific value.
• Remedy: Perfrom the work according to the instructions in the service manual of the feeder.
