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

ADF/scanner trouble

2

Check conditions in which error occurred

Check whether the error occurred only during 2-sided printing, or whether the error occurred during both 2-sided or one-sided printing.

Occurs during both.
Go to step 3

    If there are smudges at the center of the paper, check the various feed rollers.
  • CR side surface
    Check that there is no dust or ink adhered.

Nozzle condition is excellent?

 Go to step 4

Clean the corresponding parts.

* When cleaning the gaps in the SMAP driven roller, you can raise the driven roller a little to make cleaning easier by executing [Settings] > [Maintenance] > [Remove Scraps of Paper].

* If there are large ink deposits, check that there is no ink leaking.

If there is noticeable dirt on the platen, operation without paper may have occurred so execute cleaning and check the following items as well.

  1. Paper size setting of main unit / driver
  2. Check the PW sensor operation (refer to step 7 below)

  2. Check the wiper parts
    • Check that there is not soiling or damage to the wiper parts
    • With the cap sliders drawn to the right side, rotate the PF gears by hand and check that the wipers move up and down.
 Go to step 6
  • When cap/wiper is dirty
    • Cleaning the cap surface / wiper part
  • When capping failure of the nozzle surface is confirmed
  • When the wiper part breakage/wiper operation failure is confirmed

If nozzle missing is not improved after performing the above, go to step 6.
