Problem
Your print is grainy, or has
misregistration or ghosting.
Colors are incorrect or
missing.
Solution
◗ Check the ink indicators and light to see if you are low on ink. (If you replace
ink cartridges with the printer turned off, the ink indicators will not be
accurate.) Replace ink cartridges if necessary, as described on page 153.
◗ Run a nozzle check and cleaning cycle. See page 148 for instructions.
◗ Align the print head, as described on page 152.
◗ Make sure the Media Type setting in the printer software is correct.
◗ 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 the High Speed setting.
You may need to adjust your advanced media control settings (page 94 for Mac
OS X) or paper configuration settings (page 126 for Windows). Check these
settings:
◗ Make sure Paper Thickness setting is correct for your paper.
◗ 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 83.
◗ Make sure the Media Type setting in the printer software is correct.
◗ If you are using the color management features in Photoshop or another
application, you must turn off color management in the printer driver. See
page 93 (Mac OS X) or page 114 (Windows).
◗ Adjust the Color Density setting in the Paper Configuration utility.
◗ If you're using a third-party RIP or non-Epson media, custom color profiles
will give you the best color reproduction.
◗ If you're using cut sheet media, make sure the printable side is face-up.
◗ Run a nozzle check and cleaning cycle; see page 148.
◗ Check the expiration date printed on each of the ink cartridges. If the
cartridge is too old, replace it as described on page 153.
◗ Check the ink indicators and light, and replace ink cartridges if your ink
supply is low, as described on page 153. (If you replace ink cartridges with
the printer turned off, the ink indicators will not be accurate.)
◗ Make sure color settings in your application or printer software are correct.
