• Code: C-2803 E5
• Description: TCR output abnormality.
  When the TCR sensor (TCRS) control voltage cannot be adjusted within 7.6V to 6.2V
• Causes: TCR sensor (TCRS) Printer control board (PRCB)

• Code: C-2803 E6
• Description: When the detection of the toner control patch is abnormal for the D/A check
• Causes: IDC sensor (IDCS) Printer control board (PRCB)

• Code: C-2804
• Description: Toner density abnormality.
  - When the L detection output is in excess of 2.6 V before the toner remaining sensor (PZS) detects a no toner condition, toner density does not recover even when toner is automatically supplied.
• Causes: IDC sensor (IDCS) Printer control board (PRCB)
