• Code: SC835-00
• Description: Self-diagnostic error: Centronic device [xxxx]: Detailed error code
• Causes: [1102] Verify error The loopback connector is connected but check results is an error. • IEEE1284 connector error • Centronic loopback connector defective Replace the controller board. [110C] DMA verify error The loopback connector is connected but check results is an error. • ASIC device error • IEEE1284 connector error • Centronic loopback connector is defective Replace the controller board. [1120] Loopback connector undetected Centronic loopback connector is not connected for detailed selfdiagnostic test. • Centronic loopback connector not connected correctly • Centronic loopback connector is defective • ASIC device is defective • Connect the centronic loopback connector • Replace the centronic loopback connector • Replace the controller board.
• Remedy:

• Code: SC838-00
• Description: Self-diagnostic Error: Clock Generator [xxxx]: Detailed error code
• Causes: [2701] Verify error A verify error occurred when setting data was read from the clock generator via the I2C bus. • Defective clock generator • Defective I2C bus • Defective I2C port on the CPU
• Remedy: Replace the controller board.

• Code: SC839-00
• Description: Self-diagnostic Error: Serial Flash [xxxx]: Detailed error code
• Causes: [9001] Serial Flash access error USB NAND Flash ROM cannot be read. Defective controller board
• Remedy: Replace the controller board.

• Code: SC840-00
• Description: EEPROM access error
• Causes: • During the I/O processing, a reading error occurred. The 3rd reading failure causes this SC code. • During the I/O processing, a writing error occurred.
• Remedy: • Defective EEPROM

• Code: SC841-00
• Description: EEPROM read data error. Mirrored data of the EEPROM is different from the original data in EEPROM.
• Causes: Data in the EEPROM is overwritten for some reason.
• Remedy:

• Code: SC842-01
• Description: Insufficient Nand-Flash blocks (threshold exceeded) At startup, or when machine returned from low power mode, the Nand- Flash status was read and judged that the number of unusable blocks had exceeded threshold, and then SCS generated the SC code.
• Causes: Number of unusable blocks exceeded threshold for Nand-Flash
• Remedy: Replace the controller board.

• Code: SC842-02
• Description: Number of Nand-Flash block deletions exceeded At startup, or when the machined returned from low power mode, the Nand-Flash was read and judged that the number of deleted blocks had exceeded threshold, and then SCS generated this SC code.
• Causes: Number of blocks deleted exceeded threshold for Nand-Flash
• Remedy: Replace the controller board.

• Code: SC853-00
• Description: Bluetooth device connection error The Bluetooth hardware (USB type) was connected after the machine was turned on.
• Causes: The Bluetooth hardware (USB type) was connected after the machine was turned on.
• Remedy: Always connect the Bluetooth device (USB type) before the machine is turned on.
