Learn how to print and examine the nozzle check pattern of the imagePROGRAF PRO-300.


The following video will walk you through the process outlined below.

Print the nozzle check pattern to determine whether the ink ejects properly from the print head nozzle.

 If any ink tanks are low, the nozzle check pattern will not be printed correctly. Replace any low ink tanks.

You will a sheet of A4 or Letter-sized plain paper.

  1. Make sure that the printer is powered on.

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

  3. Select Maintenance on the HOME screen.

  4. Select Nozzle Check.

    Select Nozzle Check (outlined in red)

    The confirmation screen will appear.

  5. Select Yes.

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

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 streaks in the pattern D.

    Nozzle check pattern example

    • A: No missing lines/No horizontal streaks

    • B: Lines are missing/Horizontal streaks are present

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

    Figure: Select All A or Also B Figure: Select All A or Also B

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

    Cleaning is not required. Select All A, confirm the message, then select OK.

    The screen will return to the Maintenance screen.

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

    Cleaning is required. Select Also B, then select Yes on the cleaning confirmation screen.

    Select an ink group containing missing lines or horizontal streaks to perform cleaning.

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

    Figure: CO bands (dark gray) are printed over the black ink

    If the pattern D or any color in the pattern C is not printed:
