Printing the Nozzle Check Pattern
This machine prints by ejecting ink from its print head nozzles, which can occasionally become clogged. If you
notice that prints are patchy or do not contain a certain colour, the nozzles might be clogged. To check
whether this is the case, print the nozzle check pattern using the following procedure. If the test pattern
indicates that the nozzles are clogged, clean the print heads.
