• Code: 10A5
• Description: Marketing area error
  • Marketing area error is detected when reading the backup media of the machine is finished. • Hardware signal is not fixed when the Boot started.
• Remedy: 1 Disconnect and then connect the power cord. Turn OFF the power switch, wait for 10 sec. or more, and turn ON the power switch. 2 Rewrite the firmware. 3 Change PRCB

• Code: 133B
• Description: FNS communication error (FS-529)
  When the FS control board (FSCB) is receiving data, a communication error is detected.
• Remedy: 1 Disconnect and then connect the power cord. Turn OFF the power switch, wait for 10 sec. or more, and turn ON the power switch. 2 Rewrite the firmware. 3 JSCB F1 conduction check 4 JSCB F2 conduction check 5 Change FSCB

• Code: 1340
• Description: FPGA configuration error
  When a configuration check is performed on the extended IC chip (FPGA) located on the printer control board (PRCB), error is detected.
• Remedy: 1 Reboot the machine. 2 Rewrite the firmware. 3 Change PRCB

• Code: 13D0
• Description: Main backup media access error
  • When an error is detected at the data reading process. • The machine writes and reads data, and judges that the data has error. Then the machine performs the same process and judges again that the data has error. • When counter values are read, error is detected. • The machine detects that it does not have EEPROM.
• Remedy: 1 Reboot the machine. 2 Check the EEPROM on the PRCB for proper connection and correct as necessary. 3 Change PRCB 4 Change EEPROM

• Code: 13F0
• Description: Engine control malfunction
  Engine control malfunction is detected with port monitor control.
• Remedy: 1 Check the connectors on the PRCB for proper connection and correct or change as necessary. 2 Rewrite the firmware. 3 Change PRCBEPR

• Code: 1402
• Description: FS NVRAM memory error (FS-529)
  When the power switch is turned ON, malfunctioning of the non-volatile memory on the FS control board (FSCB) is detected.
• Remedy: 1 Disconnect and then connect the power cord. Turn OFF the power switch, wait for 10 sec. or more, and turn ON the power switch. 2 Rewrite the firmware. 3 Change FSCB
