Your print has vertical
banding.
If none of these suggestions help, try the solutions in the following table.
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 157.
◗ Run a nozzle check and cleaning cycle. See page 152 for instructions.
◗ Turn off the High Speed setting. See page 108 for instructions.
◗ 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.
◗ 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 advanced media control settings (page 119 for Mac OS X
10.6 & 10.5) or paper configuration settings (page 100 for Windows or page 133
for Mac OS X 10.4.11). Check these settings:
◗ Make sure the Paper Thickness setting is correct for your paper.
◗ 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 82.
◗ Turn off the High Speed setting. See page 108 for instructions.
◗ Align the print head; see page 156.
