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.
