Deep Print Head Cleaning

If print quality does not improve by the standard cleaning of the print head, clean the print head deeply. Cleaning the print head deeply consumes more ink than the standard cleaning of the print head, so clean the print head deeply only when necessary.

Important

  • When performing the print head deep cleaning, check the free space in the maintenance cartridge. If there is not enough free space, replace with the new maintenance cartridge. In the case of shortage of free space in the maintenance cartridge, a message is displayed and the cleaning cannot be performed.

Items to Prepare

When Using Rolls

Unused roll at least 11.69 in. (297.0 mm) wide

When Using Sheets

One unused sheet of A4 or larger size paper

  1. Load paper.

  2. Select (Setup) on the HOME screen.

  3. Select Maintenance.

  4. Select Deep Cleaning.

  5. Check message and select Yes.

  6. Select All colors, Color or BK.

    The printer starts cleaning the print head deeply. This takes about 2 to 3 minutes.

    Important

    • Do not perform any other operations until the printer completes the deep cleaning of the print head.

  7. Check message and select Yes.

  8. Select Roll paper or Top feed.

    The nozzle check pattern will be printed.

  9. When the completion message appears, select OK.

  10. Check the print result.

    Check if there are missing lines in the pattern C or horizontal streaks in the pattern D.

    • A: No missing lines/No horizontal streaks
    • B: Lines are missing/Horizontal streaks are present

Important

  • If the problem is not resolved, turn off the power and clean the print head deeply again after 24 hours. Do not unplug the power cord when turning off the power.

  • If there is no improvement after repeating Deep Cleaning twice, perform Replace Ink in Print Head.
