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.

You need to prepare: a sheet of A4 or Letter-sized plain paper

1. Make sure that the power is turned on.

2. Load a sheet of A4 or Letter-sized plain paper in the cassette.

   After pushing the cassette back, the paper information registration screen is displayed on the touch screen. Select A4 or Letter for Page size and Plain paper for Type, then tap OK.

   

   If a message is displayed on the screen, follow the directions in the message to complete registration.

3. Open the paper output tray gently.

4. Clean the print head deeply.

   1. Flick the HOME screen, then tap Setup.

      The setup menu screen will appear.

   2. Tap Maintenance.

      The Maintenance screen will appear.

   3. Tap Deep cleaning.

      

      The confirmation screen will appear.

   4. Tap Yes.

      The machine starts cleaning the print head deeply.

      Do not perform any other operations until the machine completes the deep cleaning of the print head. This takes about 1 to 2 minutes.

      The pattern print confirmation screen will appear.

   5. Tap Yes.

      The nozzle check pattern will be printed.

   6. When the completion message appears, tap OK.

5. Examine the nozzle check pattern.

Note

If a particular color is not printed properly, replace the ink tank of that color.
If the problem is not resolved, turn off the power and clean the print head deeply again after 24 hours.
If the problem is still not resolved, the print head may be damaged. Contact the service center.
 

Examining the Nozzle Check Pattern

Examine the nozzle check pattern, and clean the print head if necessary.

1. Check if there are missing lines in the pattern (C) or horizontal white streaks in the pattern (D).

   
   • (A) No missing lines/No horizontal white streaks
   • (B) Lines are missing/Horizontal white streaks are present
   • (E) Number of sheets printed so far
      

2. Select the pattern that is closer to the printed nozzle check pattern on the confirmation screen.

   

   For (A) (no missing lines or no horizontal white streaks) in the pattern (C) and pattern (D):

   1. The cleaning is not required. Tap All A.

   2. Confirm the message, then tap OK.

      The screen will return to the Maintenance screen.

   For (B) (lines are missing or horizontal white streaks are present) in the pattern (C) or pattern (D), or in patterns:

   1. The cleaning is required. Tap Also B.

      The cleaning confirmation screen will appear.

   2. Tap Yes.

      The machine starts cleaning the print head.

Note

• The total number of sheets printed so far is shown in increments of 50 sheets on the printout of the nozzle check pattern.
