Problem
Your print is grainy, or
has misregistration or
ghosting.
Solution
◗ 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 88 for Mac OS X or page 111 for
Windows). Check these settings:
◗ Make sure the Paper Thickness setting is correct for the paper you're printing on.
◗ 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 75.
◗ Check the ink indicators and light to see if you are low on ink. Replace ink
cartridges if necessary, as described on page 127.
◗ Run a nozzle check and cleaning cycle. See page 122 for instructions.
◗ Align the print head, as described on page 126.
◗ 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 up.
◗ Choose a higher resolution, such as 2880 dpi.
◗ Turn off High Speed in your Advanced settings.
