• Code: E263-0002
• Description: Current Sensor error
  An error is detected in the value of the Current Sensor (SE601) (the value remains at the lower limit).
• Remedy: 1. Check the connection between the AC Driver PCB and the Main Driver PCB (connector disconnection, open circuit, short circuit of harness). AC Driver side: J615, Main Driver side: J103 2. Replace the AC Driver PCB. 3. Replace the Main Driver PCB (PCB2).

• Code: E263-0003
• Description: Error in Current Sensor accuracy
  The value of the Current Sensor (SE601) is not within the range of reference value.
• Remedy: 1. Check the connection between the AC Driver PCB and the Main Driver PCB (connector disconnection, open circuit, short circuit of harness). AC Driver side: J615, Main Driver side: J103 2. Replace the AC Driver PCB. 3. Replace the Main Driver PCB (PCB2).

• Code: E270-0001
• Description: Error in paper front vertical scanning synchronous signal
  Vertical scanning synchronous signal (VSYNC) is not sent appropriately from the CMOS PCB (Scanner Unit (Paper Front)), so the image error occurs or the operation stops abnormally.
• Remedy: 1. Connector disconnection/open circuit of the Scanner Unit (Reader). 2. Connector disconnection/open circuit of the Reader Controller PCB (PCB1). 3. Failure of the Scanner Unit (Reader). 4. Failure of the Reader Controller PCB (PCB1).

• Code: E270-0002
• Description: Error in horizontal scanning/vertical scanning synchronous signal
  Due to the horizontal scanning synchronous signal (HSYNC) error, the vertical scanning synchronous signal (VSYNC) is not sent, so the image error occurs or the operation stops abnormally.
• Remedy: 1. Connector disconnection/open circuit of the Scanner Unit (Reader/DADF). 2. Connector disconnection/open circuit of the Reader Controller PCB (PCB1). 3. Failure of the Scanner Unit (Reader/DADF). 4. Failure of the Reader Controller PCB (PCB1).

• Code: E270-0101
• Description: Error in paper back vertical scanning synchronous signal
  Vertical scanning synchronous signal (VSYNC) is not sent appropriately from the CMOS PCB (Scanner Unit (Paper Back)), so the image error occurs or the operation stops abnormally.
• Remedy: 1. Connector disconnection/open circuit of the Scanner Unit (DADF). 2. Connector disconnection/open circuit of the Reader Controller PCB (PCB1). 3. Failure of the Scanner Unit (DADF). 4. Failure of the Reader Controller PCB (PCB1).

• Code: E280-0001
• Description: Communication error between Reader Controller PCB (PCB1) and Scanner Unit (Reader)
  Within the specified period of time, communication between the Reader Controller PCB and Scanner Unit (Paper Front) is not started.
• Remedy: 1. Connector disconnection/open circuit of the Scanner Unit (Reader). 2. Connector disconnection/open circuit of the Reader Controller PCB (PCB1). 3. Failure of the Scanner Unit (Reader). 4. Failure of the Reader Controller PCB (PCB1).

• Code: E280-0101
• Description: Communication error between Reader Controller PCB (PCB1) and Scanner Unit (DADF)
  Within the specified period of time, communication between the Reader Controller PCB and Scanner Unit (Paper Back) is not started.
• Remedy: 1. Connector disconnection/open circuit of the Scanner Unit (DADF). 2. Connector disconnection/open circuit of the Reader Controller PCB (PCB1). 3. Failure of the Scanner Unit (DADF). 4. Failure of the Reader Controller PCB (PCB1).

• Code: E301-0001
• Description: Paper front light intensity NG
  Light intensity is below the reference level at paper front shading.
• Remedy: Failure of the Scanner Unit (Reader).
