Note:
Based on the perspective shown in the illustration, Package A is always the row of nozzles
on the left side of a printhead and Package B is always the row of nozzles on the right
side of a printhead.
Once you have identified the particular printhead that has nozzles out as indicated by

the nozzle check print, you can perform the following procedure to correct the nozzle
dropouts.
How to Correct Nozzle Dropouts
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.
Note:
If the nozzle dropouts are only indicated on a single printhead you can perform mainte-
nance on a select printhead as indicated in the procedure below.
Print another nozzle check and repeat step 1, if necessary.
