Checking for Nozzle Clogging

If the print is blurred or has different color threading, print a nozzle check pattern to see if each nozzle of the print head is not clogged.

Note

Items to Prepare
A sheet of A4 or Letter-sized plain paper

  1. Load a single sheet of A4 or Letter size plain paper in the top feed.

    After loading paper, the paper information registration screen for the top feed is displayed.

    Select A4 or Letter for Page size and Plain paper for Type, select Register, then press the OK button.

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

    Important

    • The manual feed tray is not available for the nozzle check pattern print procedure. Be sure to load paper in the top feed.

  2. Open the paper output tray gently.

    Open the output tray extension gently, then pull out the paper output support.

  3. Select Maintenance on the HOME screen.

  4. Select Nozzle Check.

    The confirmation screen will appear.

  5. Select Yes.

    The nozzle check pattern will be printed and two pattern confirmation screens will appear on the LCD.

  6. 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
    • E: Number of sheets printed so far

    Note

    • Because CO ink is colorless, its pattern is printed over the MBK ink pattern. Check for horizontal streaks (F) in the dark gray bands of the pattern.

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

    If pattern C has no missing lines in all three groups and pattern D has no horizontal streaks (A):

    Cleaning is not required. Select All A, then press the OK button.

    Confirm the message, then press the OK button.

    The screen will return to the Maintenance screen.

    If pattern C has missing lines in any of the three groups or pattern D has horizontal streaks (B):

    The cleaning is required. Select Also B, then go to next step.

  8. Select Yes on the cleaning confirmation screen.

    The printer starts cleaning the print head.

    Important

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

  9. Check message and select Yes.

    A nozzle check pattern is printed and two pattern confirmation screens appear on the LCD.

  10. Repeat steps 6 through 9.

Important

  • If there is no improvement after repeating the cleaning process twice, perform Deep Cleaning.
