Printhead Maintenance - How to Correct Nozzle Dropouts

Procedure
1.
If there are only a few nozzle dropouts per printhead try suctioning the
affected printheads again without purging. If many nozzles are out,
perform Printhead Maintenance again.
2.
Print another nozzle check and repeat step 1.
3. If nozzle dropouts still remain, swab that printhead.
Result
When a printhead does not have any dropouts, it will look like the Nozzle
Check print illustrated below.
NOTE
However, in this case there is an indication of mis-direction in one of the
nozzles illustrated by the white line.This may not affect image quality, but
it could, if multiple adjacent nozzles have this problem. If it does show up
in a print job it will require a service call to adjust the printhead.
