Print Nozzle Check Pattern / Self Test from unit
Instructions to print the nozzle check directly from the printer. By printing a nozzle check pattern, you can check whether ink ejects normally from the print head nozzles.
- Load letter sized plain paper in the sheet feeder or cassette.
- Press and hold the <Resume/Cancel> button.
- When the Power lamp blinks twice, release the button.
Note: The Power lamp blinks and the nozzle check pattern will be printed. (After the printer initializes, it will take about 10 seconds until printing is completed.)
- Examine the nozzle check pattern output.
| Correct Nozzle Pattern | Incorrect nozzle pattern |
- Lines are aligned systematically.
- Black ink: There are no missing lines and lines are aligned systematically.
- Color ink: There are no white streaks.
| - No ink is ejected. (Nothing appears on the output.)
- Some colors of ink are not ejected completely. (Sample: Black ink is not ejected.)
- Some black ink patterns are missing.
- White streaks appear in color ink.

If the output is correct, the print head is normal.
If the output is incorrect, perform the following steps:
- Perform a deep print head cleaning
- Print the nozzle check pattern again
- If any lines or colors are missing from the nozzle check pattern perform two more deep print head cleanings
Caution: Avoid performing more than three deep cleanings in a twenty-four hour period.
- Print the nozzle check pattern again
If the nozzle check pattern is still incorrect, service may be required.
