• Code: 0030
• Description: FAX control PWB system error
  Processing with the fax software was disabled due to a software problem.
• Causes: FAX control PWB
• Remedy: 1. Turn the main power swtch off and after 5 seconds, re-mount the FAX controller PWB, then turn power on. 2. Reinstall the fax software. 3. Replace the FAX control PWB.

• Code: 0060
• Description: Main/Engine PWB mismatch
  Unmatching engine and engine sub boards. Defective engine subboard
• Causes: Main/Engine PWB
• Remedy: 1. Turn the main power swtch off and after 5 seconds, then turn power on. 2. Replace the main/engine PWB.

• Code: 0100
• Description: Backup memory device error
• Causes: EEPROM (Main/Engine PWB)
• Remedy: 1. Turn the main power swtch off and after 5 seconds, then turn power on. 2. Check that the EEPROM on the main circuit PWB is peroperly installed on the main circuit PWB and, if not, re-install it. 3. Replace the main/engine PWB.

• Code: 0120
• Description: MAC address data error
  For data in which the MAC address is invalid.
• Causes: EEPROM (Main/Engine PWB)
• Remedy: 1. Turn the main power swtch off and after 5 seconds, then turn power on. 2. Check the MAC address on the network status page. 3. If it is blank, obtain an EEPROM with its MAC address written from the service support and install. 4. Replace the main/engine PWB.

• Code: 0150
• Description: Backup memory read/write error (main/engine PWB)
  No response is issued from the device in reading/writing for 5 ms or more and this problem is repeated 5 times successively. Mismatch of reading data from 2 locations occurs 8 times successively. Mismatch between writing data and reading data occurs 8 times successively.
• Causes: EEPROM (Main/Engine PWB)
• Remedy: 1. Turn the main power swtch off and after 5 seconds, then turn power on. 2. Check that the EEPROM is peroperly installed on the main/engine PWB and re-install it. 3. Replace the main/engine PWB. 4. Check the EEPROM and if the data are currupted, contact the service support.

• Code: 0160
• Description: Backup memory data error (main/engine PWB)
  Reading data from EEPROM is abnormal.
• Causes: EEPROM
• Remedy: 1. Turn the main power swtch off and after 5 seconds, then turn power on. 2. Execute U021 - memory initializing.(see page 1-3-19) 3. If the EEPROM data are currupted, contact the service support.

• Code: 0170
• Description: Billing counting error
  The values on the main circuit PWB and on the engine do not match for any of charging counter, life counter, and scanner counter.
• Causes: EEPROM. Main/Engine PWB.
• Remedy: EEPROM 1. Check that the EEPROMs installed in the main/engine PWB are correct and, if not, use the correct EEPROM for the model. 2. If the EEPROM data are currupted, contact the service support.
  Main/Engine PWB Replace the main/engine PWB.

• Code: 0180
• Description: Machine number mismatch
  Machine number of main/ engine does not match.
• Causes: Data damage of EEPROM.
• Remedy: 1. Confirm the machine data for the main/ engine units by using U004. 2. If the serial number data of different models is alternately displayed, install the correct EEPROM in the PWB of the wrong serial number data. 3. Contact the Service Support.
