Chapter 10 Printer Maintenance

Printhead Maintenance

Check Print Quality

Print a Nozzle Check to see if any nozzles are out.

Print an image to make sure there is no banding or other print quality issues.

Maintenance for Persistent Nozzle Outs

If some nozzles are still out after the print quality check, open the maintenance
station cover, raise the carriage, and then suction only the printheads that still show
nozzles out.

Print another Nozzle Check to see if any nozzles are still out.

Note:

If problems still persist, perform the swab procedure on the affected printhead

(See How to Swab a Single Printhead).
