Problems and Solutions 47
■ Make sure the type of paper you loaded matches the paper size and paper type
settings on the control panel or in your printer software (see page 31).
■ For the best print quality, use Epson special paper (see page 20) and genuine
Epson ink cartridges (see page 38).
■ If you notice light or dark bands across your printouts or they are too faint,
you may need to clean the print head (see page 37). This unclogs the nozzles
so they can deliver ink properly. Run a nozzle check as described on page 36
to see if the print head needs cleaning.
■ Clean the print head as described on page 37.
■ If you notice jagged vertical lines, you may need to align the print head. See
your online User’s Guide for instructions.
■ The ink cartridges may be low on ink. Check your cartridge status (see
page 38) and replace cartridges, if necessary (see page 39).
■ If a dotted line appears in the image, clean the document table glass with a
soft, dry, lint-free cloth (paper towels are not recommended and may
permanently scratch the surface), or use a small amount of glass cleaner on a
soft cloth, if necessary. Do not spray glass cleaner directly on the glass.
