Checking the Print Head Nozzles
If your printouts are faint or have gaps in them, some of the
nozzles in the print head may be clogged or ink may be
running low in one or more of the ink cartridges. Follow the
steps below to check the print head nozzles.
1. Make sure the Epson Stylus CX7800 is turned on but not
printing, and the H ink low icon is not displayed in the
upper-left corner of the LCD screen. (If the H ink low icon
is displayed, you need to replace an ink cartridge; see
page 15.)

Cleaning the Print Head
If your printouts are unexpectedly light or faint, or you notice
light or dark bands across your printout, you may need to
clean the print head. This unclogs the nozzles so they can
deliver ink properly. Run a nozzle check as described on
page 14 to see if the print head needs cleaning.
