Successfully completed

Process control self-check successfully completed.

Check the Vsg adjustment. See the "Vsg Adjustment Result" following this table.

41

Vt error

Vt maximum or minimum error is detected.

  • Defective development unit

Vt maximum error and an image is faint:

  1. Replace the toner supply pump unit.

Vt maximum error and an image is O.K:

  1. Replace the development unit.
  2. Replace the BICU board.

Vt minimum error:

  1. Replace the development unit.
  2. Replace the BICU board.

53

ID sensor coefficient (K5) detection error

Not enough data can be sampled.

  • Solid image is not sufficient density:
  1. Retry the process control.
  2. Replace the ID sensors.
  3. Replace the BICU board.
  • Solid image is O.K.
  1. Replace the ID sensors.
  2. Replace the BICU board.
  • ID sensor is dirty:
  1. Clean the ID sensors.
  2. Retry the process control.

54

ID sensor coefficient (K5) maximum/ minimum error

When the K5 is more than the value of SP3-362-003 or less than the value of SP3-362-004, the error 54 is displayed.

  • ID sensor pattern density is too high or low.
  • ID sensor or shutter is defective.

Same as 53

55

Gamma error: Maximum

Gamma is out of range. 5.0 < Gamma

  • ID sensor pattern density is too high.
  • Hardware defective.

Same as 53

56

Gamma error: Minimum

Gamma is out of range.

Gamma < 0.15

  • ID sensor pattern density is too low.
  • Hardware defective.
  1. Same as 53
  2. Replace the toner supply pump unit.

57

Vk error: Maximum

Vk is out of range.

150 < Vk

Same as 53

59

Sampling data error during gamma correction

Not enough data can be sampled during the gamma correction.

  • ID sensor pattern density is too high or low.
  • Hardware defective

Same as 53

99

Unexpected error

Process control fails.

  • Power Failure

Check the power source.
