Examining The Nozzle Check Pattern; Aligning The Print Heads - Epson 800 User Manual

Maintenance and Transportation
If your print quality has not improved, repeat the steps above. If
you don't notice any improvement after doing this four or five
times, check the print quality solutions in Chapter 6.

Examining the Nozzle Check Pattern

Examine the nozzle check pattern you print after cleaning the
print heads. It should look something like this, with the lower
pattern colored cyan, magenta, 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, clean the print
heads again, as explained in the previous sections.

Aligning the Print Heads

If your printouts contain misaligned vertical lines, you may
need to align the print heads. You can align the print heads in
either of the following two ways:
With the Print Head Alignment utility in your printer
software (when the printer is on a local port rather than a
network)
Using the printer's control panel buttons
