• Code: PF-00
• Description: RIC copy inhibit command receive
  The copy inhibit command is received from the RIC (host). (By PPC communication standards.)
• Causes: Judged by the host.
• Remedy: Notification to the host

• Code: U1-01
• Description: FAX battery abnormality
  FAX backup SRAM battery voltage fall. When the battery capacity is less than the threshold value (fixed by the hardware), it is judged as an error. (Insufficient capacity of the SRAM backup battery)
• Causes: Battery life
  Battery circuit trouble
• Remedy: Case 1 Cause Battery life Check and remedy Check that the battery voltage is about 2.5V or above. Case 2 Cause Battery circuit trouble Check and remedy Check the battery circuit.

• Code: U1-02
• Description: RTC read error (combined use as FAX, on MFP control PWB)
  The read value from the RTC on the MFP control PWB is abnormal such as "EE"h.
• Causes: RTC circuit trouble
  Battery voltage fall
  Battery circuit trouble
• Remedy: Case 1 Cause RTC circuit trouble Check and remedy Make the time setup again with the key operation and check that the time advances normally. Check the RTC circuit. Case 2 Cause Battery voltage fall Check and remedy Check that the battery voltage is about 2.5V or above. Case 3 Cause Battery circuit trouble Check and remedy Check the battery circuit.

• Code: U2-00
• Description: EEPROM read/write error (MFP control)
  EEPROM write error (without retry) EEPROM magic number error.
• Causes: EEPROM trouble
  Insertion of EEPROM which is not initialized
  MFP control PWB EEPROM access circuit trouble
• Remedy: Case 1 Cause EEPROM trouble Check and remedy Check that the EEPROM is properly installed. In the simulation to prevent against delete of the counter data/adjustment values, write down the counter/adjustment values. Case 2 Cause Insertion of EEPROM which is not initialized Check and remedy Use SIM 16 to cancel the U2 trouble. Case 3 Cause MFP control PWB EEPROM access circuit trouble Check and remedy Replace the MFP control PWB.

• Code: U2-11
• Description: Counter check sum error (MFP control)
  EEPROM counter area checksum error. (If this error occurs, the process will retrieve for effective data within 8 blocks.)
• Causes: EEPROM trouble
  Control circuit runaway due to noises
  MFP control PWB EEPROM access circuit trouble
• Remedy: Case 1 Cause EEPROM trouble Check and remedy Check that the EEPROM is properly installed. In the simulation to prevent against delete of the counter data/adjustment values, write down the counter/adjustment values. Case 2 Cause Control circuit runaway due to noises Check and remedy Use SIM 16 to cancel the U2 trouble. Case 3 Cause MFP control PWB EEPROM access circuit trouble Check and remedy Replace the MFP control PWB.

• Code: U2-12
• Description: Adjustment value check sum error (MFP control)
  EEPROM counter area checksum error (If this error occurs, the process will retrieve for effective data within 8 blocks.)
• Causes: EEPROM trouble
  Control circuit runaway due to noises
  MFP control PWB EEPROM access circuit trouble
• Remedy: Case 1 Cause EEPROM trouble Check and remedy Check that the EEPROM is properly installed. In the simulation to prevent against delete of the counter data/adjustment values, write down the counter/adjustment values. Case 2 Cause Control circuit runaway due to noises Check and remedy Use SIM 16 to cancel the U2 trouble. Case 3 Cause MFP control PWB EEPROM access circuit trouble Check and remedy Replace the MFP control PWB.

• Code: U2-22
• Description: SRAM memory check sum error (MFP control)
  SRAM check sum error when turning on the power. (If this error occurs, initialize the one-touch dial and the FAX soft switches.)
• Causes: SRAM trouble
  Control circuit runaway due to noises
  MFP control PWB EEPROM access circuit trouble
• Remedy: Case 1 Cause SRAM trouble Check and remedy Initialize the communication management table registered in the SRAM and the FAX soft switch. Since the registered data are deleted, register the data again. Case 2 Cause Control circuit runaway due to noises Check and remedy Use SIM 16 to cancel the U2 trouble. Case 3 Cause MFP control PWB EEPROM access circuit trouble Check and remedy Replace the MFP control PWB.

• Code: U2-23
• Description: SRAM memory individual data check sum error
  Check sum error for every individual data in SRAM of the MFPC section when turning on the power (If this error occurs, initialize the data related to the check sum error. (Communication management table, sender's information, etc.))
• Causes: SRAM trouble
  Control circuit runaway due to noises
  MFP control PWB EEPROM access circuit trouble
• Remedy: Case 1 Cause SRAM trouble Check and remedy Automatically initialize the data related to the check sum error by turning OFF/ON the power. Since the registered data are deleted, register the data again. Case 2 Cause Control circuit runaway due to noises Check and remedy Use SIM 16 to cancel the U2 trouble. Case 3 Cause MFP control PWB EEPROM access circuit trouble Check and remedy Replace the MFP control PWB.
