2. Press OK to clear any messages on the display screen.

Faxing Problems
■ Make sure the recipient’s fax machine is turned on and working.
■ Make sure the LINE port on the CX9400Fax Series is connected to a
telephone wall jack. Verify that the telephone wall jack works by connecting a
phone to it.
■ If the line has static, press Setup, select Fax Settings, select
Communication, and turn off the V.34 and ECM (Error Correction Mode)
settings.
■ If the CX9400Fax Series is connected to a DSL phone line, you must have a
DSL filter connected to the phone jack. Contact your DSL provider for the
necessary filter.
Print Quality Problems
■ For the best print quality, use Epson papers (see page 5) and genuine Epson
ink cartridges (see page 36).
■ If you notice light or dark bands across your printouts or they are too faint,
run a nozzle check (see page 32) to see if the print head needs cleaning.
■ If you notice jagged vertical lines, you may need to align the print head. See
the on-screen User’s Guide for instructions.
■ The ink cartridges may be low on ink. Check your cartridge status (see
page 32) and replace cartridges, if necessary (see page 36).
■ If you’re copying, place the document flat against the scanner glass.
■ Clean the scanner glass with a soft, dry, lint-free cloth (paper towels are not
recommended), or use a small amount of glass cleaner on a soft cloth, if
necessary. Do not spray glass cleaner directly on the glass.
