Improving Print Quality

You can often improve print quality by doing the following:
Run a nozzle check and cleaning cycle. See page 75 for instructions.
•
Align the print head. See page 78 for instructions.
•
When you send a print job, make sure your print options are set
•
correctly. For more information, see Chapter 3 (Macintosh) or 4
(Windows).
If none of these suggestions help, try the solutions below.
Solution
Check the ink indicators and light to see if you are low on ink. Replace ink
cartridges if necessary, as described on page 79.
Run a nozzle check and cleaning cycle. See page 75 for instructions.
Align the print head from the printer's control panel, as described on page 78.
Turn off High Speed in your Advanced settings.
Make sure the Media Type setting in the printer software is correct for the media
you're printing on.
If you're using cut sheet media, make sure the printable side is face down in the
tray.
Choose a higher resolution, such as SuperPhoto - 2880dpi.
If you're using a third-party RIP and non-EPSON media, see if the RIP provides a
method for adjusting the paper feed.
Try adjusting your paper configuration settings (page 51 for Mac OS X, page 66 for
Mac OS 9, or page 83 for Windows). Check these settings:
Make sure the Paper Thickness setting is correct for the paper you're printing on.
If you're printing on thin paper that's getting saturated with ink, reduce the Paper
Suction.
Use the Paper Feed Adjustment to tune out banding. Reduce the value for white
lines, and increase it for overlapping dark lines.
If you've created a custom paper configuration, be sure to return the setting to
standard (STD) when you're done using it. See page 40.
