Examining The Nozzle Check Pattern - Epson 740 Series Manual

Examining the Nozzle Check Pattern

Examine the nozzle check pattern you print. It should look
something like this, with the lower pattern colored magenta, cyan,
and yellow:
Each staggered horizontal and straight vertical line should be
complete, with no gaps in the dot pattern. If your printout looks
okay, you're done. If any dots are missing, as shown below, clean
the print head again; see Cleaning the Print Head for instructions.
