• Code: 0170
• Description: Billing counting error Mismatch between the value of the Main/Engine PWB and EEPROM, in one of the value of billing counter, life counter, or scanner counter.
• Remedy: EEPROM (Main/ Engine PWB) 1. Check that the EEPROM installed in the Main/Engine PWB is correct and, if not, install the correct EEPROM for the model. 2. Replace the Main/Engine PWB. 3. If the EEPROM data are currupted, contact the service support.

• Code: 0180
• Description: Machine number mismatch When the power is turned on, the machine number does not match the one stored in the Main/Engine PWB.
• Remedy: EEPROM (Main/ Engine PWB) 1. Check that the EEPROM installed in the Main/Engine PWB is correct and, if not, install the correct EEPROM for the model. 2. Confirm the serial number data for the Main/Engine PWB by using U004. If the mutually different machine number data between "Machine No. (Main)" and "Machine No. (Eng)" is displayed, or if there is a difference between the actual machine number and the number of "Machine No. (Eng)", install the correct EEPROM, and then execute U004.

• Code: 0190
• Description: Backup memory device error (Main/Engine PWB) At power up, read/write data from FRAM can not be performed. (retry: 3times)
• Remedy: FRAM (Main/ Engine PWB) 1. Unplug the power cord from the wall outlet, and wait five seconds. Then plug the power cord and then turn on the power switch. 2. Check that the connectors on the Main/ Engine PWB are properly connected, and if not, re-connect them. 3. Replace the Main/Engine PWB.

• Code: 0360
• Description: Communication error between the engine ASIC During the readback data checked after data transmission, the checksum error or the video signal is not inverted. (failed 10 consecutive times)
• Remedy: Defective connector cable or poor contact in the connector 1. Reinsert the connector. 2. Check continuity within the connector wire. If none, replace the wire. Engine relay PWB (YC1) and Main/Engine PWB (YC4)
  Engine relay PWB Replace the engine relay PWB.
  Main/Engine PWB Replace the Main/Engine PWB.

• Code: 0640
• Description: Hard disk (SSD) error During the file access after Ready, the I/O error of SSD is detected. (SSD format error after rebooting. For example, System initialization, Sanitization, Encrypted format when installing security kit.)
• Remedy: SSD (optional HD- 6/7) 1. Unplug the power cord from the wall outlet, and wait five seconds. Then plug the power cord and then turn on the power switch. 2. Unplug the power cord from the wall outlet, and reinstall the HD-6/7 (SSD). 3. Check that the connection between KUIO connector on the Main/Engine PWB and HD-6/7 (SSD) is proper, and if not, re-connect them. 4. Initialize the HD-6/7 (SSD). 5. Replace the Main/Engine PWB.

• Code: 0800
• Description: Image formation problems The printing sequence JAM (J010X) is detected for 2 consecutive times.
• Remedy: Main/Engine PWB 1. Check if the problem is a printing operation error detection in a particular file, and if it is possible to obtain the reproduction of phenomena by the identification of the job that detected the error, take the job log. 2. If the problem occurs in unspecified job, check the connectors on the Main/ Engine PWB, and reattach it. 3. Replace the Main/Engine PWB.

• Code: 0830
• Description: FAX PWB flash program area checksum error The program stored in the flash memory on the FAX control PWB is broken and can not be executed. *Only 4in1 models dete
• Remedy: FAX firmware 1. Reinstall the FAX firmware.
  FAX PWB 1. Unplug the power cord from the wall outlet, and reinstall the FAX controller PWB, and then plug the power cord and turn power on. 2. Check that the connection between KUIO connector on the Main/Engine PWB and Fax PWB is proper, and if not, re-connect them. 3. Execute [Initializing] by U600. 4. Replace the FAX PWB.

• Code: 0840
• Description: Faults of RTC Check at power up. The RTC setting has reverted to a previous state. The machine has not been powered for 5 years (compared to the settings stored periodically in the EEPROM). The RTC setting is older than 00:01 on January 1, 2000. Checked periodically (at every 5 minutes) after power-up. The RTC setting has reverted to a state older than the last time it was checked. 10 minutes have been passed since the previous check.
• Remedy: Settings of RTC 1. Execute Date Setting using the system menu.
  Backup battery (Main/Engine PWB) 1. Check if the backup battery on the Main/ Engine PWB is not short-circuited. 2. Unplug the power cord from the wall outlet, and wait five seconds. Then plug the power cord and then turn on the power switch. If the same service call error is displayed, replace the backup battery
  Main/Engine PWB 1. If the communication error (due to a noise, etc.) is present with the RTC on the Main/Engine PWB, check that the PWB is properly grounded or secured by screws. 2. Replace the Main/Engine PWB.
