Improving Print Quality
You can often improve print quality by doing the following:
• Run a nozzle check and cleaning cycle. See page 122 for instructions.
• Align the print head. See page 126 for instructions.
• When you send a print job, make sure your print options are set
correctly. For more information, see Chapter 3 (Macintosh) or
