• Code: C-2702
• Description: The transfer ON/OFF operation is repeated five times after an error detection signal of the transfer is detected when the transfer is ON.
• Causes: High voltage unit (HV)

• Code: C-2703
• Description: The separation ON/OFF operation is repeated five times after an error detection signal of the separation is detected when the separation is ON.
• Causes: High voltage unit (HV)

• Code: C-2801
• Description: While in the maximum density correction, the dirt correction of the maximum density sensor is not sufficient. When this condition is detected 10 times in succession, the error code is displayed.
• Causes: Toner control sensor board (TCSB) Printer control board (PRCB)

• Code: C-2803
• Description: While in the maximum density correction, a patch for control is not output. (No output is made from the maximum density sensor.)
• Causes: Toner control sensor board (TCSB) Printer control board (PRCB)

• Code: C-2804
• Description: While in the gamma correction, the dirt correction of the gamma sensor is not sufficient. When this condition is detected 10 times in succession, the error code is displayed.
• Causes: Toner control sensor board (TCSB) Printer control board (PRCB)

• Code: C-2805
• Description: While in the gamma correction, a patch for control is not output. (No output is made from the gamma sensor.)
• Causes: Toner control sensor board (TCSB) Printer control board (PRCB)

• Code: C-2807
• Description: While in the dot diameter correction, the dirt correction of the gamma sensor is not sufficient. When this condition is detected 10 times in succession, the error code is displayed.
• Causes: Toner control sensor board (TCSB) Printer control board (PRCB)

• Code: C-2807
• Description: While in the dot diameter correction, the dirt correction of the gamma sensor is not sufficient. When this condition is detected 10 times in succession, the error code is displayed.
