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

  • If the remaining ink level is low, the nozzle check pattern will not be printed correctly. Refill the ink tanks whose ink is low.
