Print Quality Problems - Epson PRO Reference Manual

Print Quality Problems

Print quality problems can often be solved by cleaning the print
heads as described earlier in this chapter. Then print a self test
to check the print quality and help identify what the problem
may be. (Note that it may take as many as five cleaning cycles
to solve a print quality problem.)
If cleaning the print heads does not improve the print quality,
try the following:
Make sure you selected Color or Monochrome correctly in
the printer driver.
Check whether the ink cartridges are empty. Print a self test
as described in the Setup and Software Guide. After the first
page prints, the printer prints an entire page of text lines in
various colors, including black, magenta, cyan, and yellow.
If the black lines don't print, replace the black ink cartridge;
if any of the colored lines don't print, change the color ink
cartridge.
For color or complex grayscale images, turn on
MicroWeave and turn off High Speed mode.
Use a higher quality paper. For best print quality, use
EPSON special coated papers for 360 and 720 dpi or
EPSON high-quality glossy paper (720 dpi only).
Make sure the Media Type setting matches the type of
paper loaded in the printer.
If you're printing a scanned image and the colors are not
right, first try to fix the problem using your scanning
software program.
If print quality does not improve, see the following specific
problems.
