Printing problems
Printing stops when an ink cartridge is expended. If a cartridge
is expended, you must replace it to continue printing.
Print quality problems
• Make sure your paper is loaded printable side down in the
cassette (usually the whiter, brighter, or glossy side).
• If you notice light or dark bands across your printouts or
they are too faint, run a nozzle check to see if the print
head needs cleaning. See the online User’s Guide for more
information.
• The ink cartridges may be low on ink. Check your cartridge
levels and replace cartridges, if necessary. See the online
User’s Guide for more information.
Mac OS X: The standard Epson driver installs automatically.
If you want to install the PostScript driver, go to www.epson.com/wp4090downloads. Then download and
install the file.
