• Code: E247
• Description: Memory board-related error
• Remedy: Contact each sale company bases

• Code: E248-0000
• Description: SRAM error. SRAM check errors at Power ON
• Remedy: Main controller board 2

• Code: E248-0001
• Description: EEPROM error. Failure of power-on at EEPROM for the reader controller PCB (PCB1)
• Remedy: 1. Turn OFF and then ON the power. 2. Check the connection between Reader and Printer, and check that the Cable is not open-circuit. 3. Replace the Reader Controller PCB

• Code: E248-0002
• Description: EEPROM error. Failure of writing at EEPROM for the reader controller PCB (PCB1)
• Remedy: 1. Turn OFF and then ON the power. 2. Check the connection between Reader and Printer, and check that the Cable is not open-circuit. 3. Replace the Reader Controller PCB.

• Code: E248-0003
• Description: EEPROM error. Failure of reading after writing at EEPROM for the reader controller PCB (PCB1)
• Remedy: 1. Turn OFF and then ON the power. 2. Check the connection between Reader and Printer, and check that the Cable is not open-circuit. 3. Replace the Reader Controller PCB.

• Code: E270-0001
• Description: Failure of the front side vertical direction synchronization signal. The vertical direction synchronization signal (VSYNC) was not sent from the CMOS PCB (front side optical unit) correctly, and an image failure occurred or the operation stopped in failure.
• Remedy: 1. Turn OFF and then ON the power. 2. Check the connection between Reader Controller PCB and Scanner Unit PCB (Reader), and check that the Cable is not open-circuit. 3. Check the connection between Reader and Printer, and check that the Cable is not open-circuit. 4. Replace the Reader Controller PCB. 5. Replace the Scanner Unit (Reader).

• Code: E270-0002
• Description: Failure of the horizontal/vertical direction synchronization signal. The vertical direction synchronization signal (VSYNC) was not sent due to a failure of the horizontal direction synchronization signal (HSYNC), and an image failure occurred or the operation stopped in failure.
• Remedy: 1. Turn OFF and then ON the power. 2. Check the connection between Reader and Printer, and check that the Cable is not open-circuit. 3. Replace the DDI-S Cable between Reader and Printer. 4. Replace the Reader Controller PCB.

• Code: E270-0101
• Description: Failure of the backside vertical scanning direction synchronization signal. The vertical direction synchronization signal (VSYNC) was not sent from the CMOS PCB (backside optical unit) correctly, and an image failure occurred or the operation stopped in failure.
• Remedy: 1. Turn OFF and then ON the power. 2. Check the connection between Reader Controller PCB and Scanner Unit PCB (DADF), and check that the Cable is not open-circuit. 3. Check the connection between Reader and Printer, and check that the Cable is not open-circuit. 4. Replace the Reader Controller PCB. 5. Replace the Scanner Unit (DADF).
