• Code: E302-0001
• Description: Error in paper front white shading
  Error in shading RAM access The shading value is out of the specified range.
• Remedy: 1. Check that the LED of the Scanner Unit (Paper Front) is lit. 2. Check the connection between Scanner Unit (Paper Front) and LED, and check that the Cable is not open-circuit. 3. Check the connection between Reader Controller PCB and Scanner Unit (Paper Front), and check that the Cable is not open-circuit. 4. Check the condition of Shading White Plate of the Stream Read Glass (Paper Front) (scratches, dust, soil, etc.). 5. Check if Scanner Unit (Paper Front) detects HP correctly. (If it does not detect correctly, the Scanner Unit reaches to the end when DF is opened.) 6. Replace the Scanner Unit (Paper Front). 7. Replace the Reader Controller PCB.
