Procedure<\/h2>\n\n\n\n
  1. Perform image troubleshooting procedure if image density is low.<\/li>
  2. Reinstall the imaging unit.<\/li>
  3. Check the connector between the imaging unit\/M-relay CN8-BASEB CN14E for proper connection and correct as necessary. (C2553)<\/li>
  4. Check the connector between M4-BASEB CN13E for proper connection and correct as necessary.<\/li>
  5. Check the connector between M5-BASEB CN13E for proper connection and correct as necessary.<\/li>
  6. Check CPUB for proper installation and correct as necessary.<\/li>
  7. M4, M5 operation check
