-Check the pattern to see if a Printhead is not printing correctly
and, if there are defects in the pattern, recover the failing Printhead(s)
(See How to fix the Nozzle
Defects).
-If Printhead recovery does not solve the problem, replace the
failing Printhead(s) and repeat the Printhead Alignment ( See
the User’s Guide).
-If the media used is a color media try the Printhead Alignment
with opaque media with no patterns and if the error persists, replace
the Lens Cover (See Lens
Maintenance).
