CR PID excess load error (error code: 000021)

Occurrence condition

  • State in which load of CR Motor exceeds expected load

  • When rotated in the opposite direction to rotation direction (There was a sudden load error, and the motor rotated in the opposite direction in reaction to it)

Suspected cause

  • Jammed paper remained

  • CR Lock Lever failure (Inksystem Assy failure)

  • High sliding load (oil cutoff, paper dust, mist)

  • CR Scale is dirty or damaged.

  • Contact damage (contact failure)/disconnection/half insertion of CR Encoder FFC

  • CR Motor failure

  • Main Board failure.

Troubleshooting
ProcedureCheck and measureYesNo
1

Visually check the CR scanning section

  • Is there no paper jam paper and foreign object in the CR scanning section?
Go to step 2
  • Remove the jammed paper and foreign object.
2

Check the CR Lock Lever operation

  • Does the CR Lock Lever operate correctly when the power is on?
    (Is the lowering operation performed correctly?)
Go to step 3
  • Replace the Inksystem Assy.
3

Check the status of the CR Guide Frame

  • Is the CR Guide Frame dirty from paper dust or mist?
  • Is a lubrication shortage occurring?
Go to step 4
  • Lubricate the CR Unit and CR Guide Frame contacting point after cleaning.
4

Check the CR Scale state.

  • Is the CR Scale dirty or damaged?
Go to step 5
  • Clean, if dirty.
  • Replace the CR Scale in the case of damage.
5

Check the status of the CR Encoder FFC

  • Check the CR Encoder FFC to make sure that it is not inserted obliquely or damaged.
Go to step 6
  • Properly connect the CR Encoder FFC.
  • Replace the CR Encoder FFC (head FFC) in the case of damage.
6Visually check the CR Motor cable.
  • CR Motor cable disconnection or contact failure
Go to step 7
  • Replace the CR Motor.


7Replace the Main board Assy.
  • Does the error occur after replacing the Main Board Assy?
Replace the Printer Mechanism.End
