• Code: E020-XXA8
• Description: Drum/Developer-related error XX=01:Y XX=02:M XX=03:C XX=04:K XX=00:Any color
  In ATR control, the detected T/D ratio is upper than its upper limit (13%) 3 times in succession.
• Remedy: Check on toner leak from toner buffer in the developing unit, Replace the ATR sensor

• Code: E020-XXA9
• Description: Drum/Developer-related error XX=01:Y XX=02:M XX=03:C XX=04:K XX=00:Any color
  In ATR control, the detected T/D ratio is lower than its lower limit (3%) 3 times in succession.
• Remedy: Check on attachment of the developing unit, Replace the ATR sensor

• Code: E021-0001
• Description: Developing rotary error
  HP of the developing rotary fails to be detected.
• Remedy: Check on connection of the HP sensor, between the rotary motor and the DC controller PCB, Replace the HP sensor, Replace the DC controller PCB, Replace the rotary motor

• Code: E021-0002
• Description: Developing rotary error
  Flag detection timing while the developing rotary rotates is too fast or too late.
• Remedy: Check on connection of the HP sensor, between the rotary motor and the DC controller PCB, Replace the HP sensor, Replace the DC controller PCB, Replace the rotary motor

• Code: E021-0003
• Description: Developing rotary error
  The sensor fails to detect the flag when the developing rotary stops at the developing position.
• Remedy: Check on connection of the HP sensor, between the rotary motor and the DC controller PCB, Replace the HP sensor, Replace the DC controller PCB, Replace the rotary motor

• Code: E026-XX01
• Description: Toner empty error XX=01:Y XX=02:M XX=03:C XX=04:K
  After toner runs out, toner density fails to go back to normal even if toner replacement and toner recovery have been performed 5 times or more in succession.
• Remedy: Replace the toner container, Check on a position of the developing shutter

• Code: E032-0001
• Description: The counter of the NE controller fails to operate.
  A break in the count pulse signal is detected.
• Remedy: Check on a break in the cable

• Code: E045-0001
• Description: OHP sensor error
  The sampling data measured during initial multiple rotations is lower than the specific level.
• Remedy: Replace the OHP sensor
