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.

1. Load letter sized plain paper in the sheet feeder.
   
   
2. Press and hold the <Resume/Cancel> button.
   
   
3. 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.)
   
   
4. Examine the nozzle check pattern output to see if the print head should be cleaned. (see below)
    
   • If the nozzle check pattern prints out correctly, then the print head is functioning properly.
   • If the nozzle check pattern is incorrect, then a print head cleaning should be performed.
