Unplug the power cord from the wall outlet, and reinstall the SSD. 3. Check the connection failure between the KUIO connector of the main PWB and SSD, and reconnect it. 4. Initialize the SSD.

• Code: 0800
• Description: Image formation problems The printing sequence JAM (J010X) is detected for 2 consecutive times.
• Remedy: Main 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 the phenomena by the identification of the job that detected the error, and take the job log. 2. If the problem occurs in an unspecified job, check the connectors on the main PWB, and reattach it. 3. Replace the main PWB.

• Code: 0830
• Description: FAX PWB flash Program area Checksum error The program stored in the flash memory on the FAX PWB is broken and cannot be executed.
• Remedy: FAX firmware: Reinstall the FAX firmware.
  FAX PWB: 1. Unplug the power cord from the wall outlet, and reinstall the FAX PWB, and then plug in the power cord and turn the power on. 2. Check the connection failure between the KUIO connector of the main PWB and FAX PWB, and reconnect it. 3. Execute [Initializing] by U600. 4. Replace the FAX PWB.

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

• Code: 0870
• Description: FAX PWB - Main PWB image data transfer error High-capacity data transfer between the FAX PWB and the main PWB was not normally performed even if the data transfer was retried the specified times.
• Remedy: FAX PWB: 1. Unplug the power cord from the wall outlet, and wait five seconds. Reinstall the FAX PWB, and then plug in the power cord and turn the power on. 2. Check the connection failure between the KUIO connector of the main PWB and FAX PWB, and reconnect it. 3. Replace the FAX PWB.
  Main PWB: Replace the main PWB.

• Code: 0920
• Description: Fax file system error The backup data is not retained for file system abnormality of the flash memory of the FAX PWB.
• Remedy: FAX PWB 1. Execute [Initializing] by U600. 2. Reinstall the FAX firmware. 3. Unplug the power cord from the wall outlet, and wait five seconds. Reinstall the FAX PWB, and then plug in the power cord and turn the power on. 4. Check the connection failure between the KUIO connector of the main PWB and FAX PWB, and reconnect it. 5. Replace the FAX PWB.

• Code: 0970
• Description: 24V power down detect
• Remedy: Low voltage power supply PWB: 1. Check that the interlock switch (ILSW) is turned on properly by the front cover closing. 2. Check if there is a defective connection in the connector of the low voltage power supply PWB, and then check the 24V output from the YC13. 3. Replace the low voltage power supply PWB.
  Engine PWB: 1. Unplug the power cord from the wall outlet, and wait five seconds. Then plug in the power cord and then turn on the power switch. 2. Check that the connectors on the main PWB are properly connected, and if not, re-connect them. 3. Replace the engine relay PWB.

• Code: 1010
• Description: Lift motor error (main unit) The following states have been detected 5 times in succession. After the cassette is installed, the upper limit detection sensor does not turn on within 12 s. During printing, after the upper limit detection sensor detects off, and 1 s after ascending control, and the upper limit detection sensor does not detect on. In case the lock signal High is detected 500ms in succession.
• Remedy: Bottom plate: Check if the bottom plate can move smoothly and repair or replace it if any problem is found. Defective connector cable or poor contact in the connector 1. Reconnect the connector if its connection is loose. 2. If a wire is pinched by another component, or has defective conduction, replace it.
  Lift motor - Engine PWB(YC21): 30 ppm model - Engine PWB(YC4): 35/40 ppm models Lift sensor - Engine PWB(YC12): 30 ppm model - Engine PWB(YC18): 35/40 ppm models. Lift motor Drive transmission system 1. Check if the gears rotate smoothly. If not, clean the bushes and gears. 2. Check for broken gears and replace if any are found. Lift motor Replace the lift motor. Lift sensor( LS) (upper limit detection sensor) 1. Check if the lift sensor can be turned ON/OFF to suit the rise of the cassette bottom plate. 2. Replace the lift sensor. Engine PWB Replace the engine PWB.
