• Code: 0680
• Description: SSD error The SSD cannot be accessed, or the error occurs when accessing to the SSD.
• Causes: SSD, Main PWB
• Remedy: SSD 1. Turn the power switch and the main power switch off. After 5s passes, turn the main power switch and the power switch on. 2. Reinstall the SSD on the main PWB. 3. Retrieve the SSD storage data at U026, and then initialize the SSD at U024. 4. Replace the SSD.
  Main PWB Replace the main PWB.

• Code: 0800
• Description: Image processing error JAM010X is detected twice.
• Causes: Main PWB
• Remedy: Replace the main PWB.

• Code: 0830
• Description: FAX control PWB flash program area checksum error A checksum error occurred with the program of the FAX control PWB.
• Causes: FAX software, FAX control PWB
• Remedy: FAX software 1. Reinstall the fax software.
  FAX control PWB 1. Execute initializing by U600. 2. Replace the FAX control PWB.

• Code: 0840
• Description: Faults of RTC (“Time for maintenance T” is displayed) [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 (in 5- minute interval) after powered 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. After C840 is detected, the machine enters in disconnection mode after the main power switch has been switched on and off and indicates ‘Maintenance T.’
• Causes: Battery ( main PWB), Main PWB
• Remedy: Battery ( main PWB) 1. Make sure that the back-up batteries on the main PWB are not short-circuited. 2. Reset Maintenance T by executing U906. 3. If the same C call is displayed when power is switched on and off, replace the back up battery. 4. If communication error (due to a noise, etc.) is present with the RTC on the main circuit PWB, check the PWB is properly grounded.
  Main PWB Replace the main PWB.

• Code: 0870
• Description: PCFAX control PWB to main PWB high capacity data transfer error High-capacity data transfer between the FAX control PWB and the main PWB of the machine was not normally performed even if the data transfer was retried the specified times.
• Causes: FAX control PWB, HDD, Main PWB
• Remedy: FAX control PWB 1. Turn the main power swtch off and after 5 seconds, re-mount the FAX controller PWB, then turn power on. 2. Replace the FAX control PWB.
  HDD Execute U024 to initialize the HDD.
  Main PWB Replace the main PWB.

• Code: 0920
• Description: Fax file system error The backup data is not retained for file system abnormality of flash memory of the FAX control PWB.
• Causes: FAX control PWB
• Remedy: 1. Execute initializing by U600 (Refer to the FAX service manual). 2. Replace the FAX control PWB.

• Code: 0980
• Description: 24 V power down detect If a 24V power disconnection signal is observed and a 12V power disconnection signal is observed simultaneously for one second.
• Causes: Power source PWB
• Remedy: 1. Check the +24V output is given at YC5 of the power circuit PWB. 2. Replace the power source PWB

• Code: 1010
• Description: Lift motor 1 error Lift error that occurs when the lock signal does turn off 510 msec in succession after turning on the cassette lift motor 1 has occurred five times in succession.
• Causes: Cassette lift base elevating mechanism. Lift motor 1. Lift sensor 1. Engine PWB
• Remedy: Cassette lift base elevating mechanism Check that the cassette base can be manipulated smoothly, if not, repair or replace.
  Lift motor 1 1. Check that the cassette base has been ascended. 2. Check the drive gear can rotate or they are not unusually loaded and, if necessary, replace. 3. Confirm that the wiring connector is firmly connected and, if necessary, connect the connector all the way in. Lift motor 1 and Engine PWB (YC13) 4. If the wiring is disconnected, shorted or grounded, replace the wiring. 5. Replace the lift motor 1.
  Lift sensor 1 1. Check that the sensor is correctly positioned. 2. Confirm that the wiring connector is firmly connected and, if necessary, connect the connector all the way in. Lift sensor 1 and Engine PWB (YC17) 3. If the wiring is disconnected, shorted or grounded, replace the wiring. 4. Replace the lift sensor1.
  Engine PWB 1. Check the engine software and upgrade to the latest, if necessary. 2. Replace the engine PWB.
