Troubleshooting
ProcedureCheck and measureYesNo
1

Check whether printing or copying

  • Check whether the symptom occurs with printing or with copying.

Occurs with printing and copying. Go to step 2

Occurs with copying only. Refer to ADF/SCN trouble.


2

Check the settings

Check that the print settings and paper type setting is correct.

Go to step 3

Change the settings.

Note / 補足

When the phenomenon is improved: Explain that the phenomenon is caused due to an erroneous print setting, and get the setting corrected.


If the symptom continues to occur, go to step 3.

3

Check the paper

Print with standard paper and check that there is no character distortion or blurring.

Go to step 4

Recommend using the standard paper.

4

Check the ink

  • Check that genuine ink packs are attached.
Go to step 5
  • Recommend using genuine ink packs.
  • Confirm recurrence by a genuine ink pack.
    (It is necessary to fill ink due to ink replacement inside the ink path.)

If the symptom continues to occur, go to step 5.

5

Check the nozzle check pattern.
Print nozzle check patterns and check that there are no nozzles missing or deflected, and that print results are good.

Go to step 6

Carry out head cleaning following the nozzle missing table below.

StrengthNumber of missing nozzles
CL11 to 5
CL26 to 20
CL321 or more

*If nozzle missing is not improved, refer to Nozzles missing.


If the symptom continues to occur, go to step 6.

6

Check the PG
Check the PG with the thickness gauge and check that it is within the specified value range (1.55 ±0.10 mm).

Go to step 7

Perform the PG adjustment.

If the symptom continues to occur, go to step 7.

7

Check the Temperature and Humidity Sensor

  1. Perform the Temperature and Humidity Sensor check from the adjustment program, and check the output value.

    <At Temperature and Humidity Sensor damage, error judgment standard>

    StatusValue
    Disconnection0 degrees C or below
    Short-circuiting60 degrees C or above
  2. Touch the Temperature and Humidity Sensor with your hand, and check the change in the output value. Does the Temperature and Humidity Sensor operate normally?

Replace the Print Head.

Replace the Temperature and Humidity Sensor.
