Printing a Nozzle Check Pattern

nozzle check pattern. Print the pattern if printing becomes faint, or if a specific color fails to print.
The procedure for printing a nozzle check pattern is as follows:
Print Nozzle Check Pattern
1. Open the printer driver setup window
2. Load paper in the printer
3. Click Print Nozzle Check Pattern on the Maintenance tab
The Print Nozzle Check Pattern dialog box opens.
4. Select feed position
Select the feed position from the displayed dialog box.
5. Print a nozzle check pattern
Make sure that the printer is on and click OK .
Printing of the nozzle check pattern begins.
Click OK when the confirmation message appears.
6. Check the print result
Check the print results.
(A) As long as the horizontal lines are in line, and not missing, the nozzle is working normally.
(B) Where the horizontal lines are not in line or are missing, the color nozzle is blocked.
Note
• From the nozzle check pattern printing results, if it becomes patchy or there are areas that
cannot be printed, use Print Head Cleaning to clean the print heads.
Once cleaning is complete, print the nozzle check pattern again and check the results.
