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.)

You can also check the nozzles with software when connected to a

computer; see your on-screen User's Guide for details.

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.
