Maintaining ink cartridges
In addition to the following tasks that you can perform, your printer performs an automatic maintenance
cycle every week if it is plugged into an electrical outlet. It will briefly come out of Power Saver mode or
will temporarily power on if it is turned off.
Aligning the printhead
If the characters or lines on your printed image appear jagged or wavy, then you may need to align the
printhead.
Using the printer control panel
1 Load plain paper.
2 From the home screen, navigate to:
> More Options > Align Printer
An alignment page prints.
Note: Do not remove the alignment page until printing is finished.

If you aligned the cartridges to improve print quality, then print your document again. If print quality has
not improved, then clean the printhead nozzles.
Cleaning the printhead nozzles
Poor print quality is sometimes due to clogged printhead nozzles. Clean the printhead nozzles to improve
the quality of your prints.
Notes:
• Cleaning the printhead nozzles uses ink, so clean them only when necessary.
• Deep cleaning uses more ink, so try the Clean Printhead option first to save ink.
• If the ink levels are too low, then you must replace the ink cartridges before you can clean the
printhead nozzles.
