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 38 to see if the print head needs cleaning.
Note: 
Print head cleaning uses ink, so clean it only if quality declines and the nozzle check 
indicates that the print head needs to be cleaned.
1. Make sure the Epson Stylus CX7800 is turned on but not printing, and the 
 ink low icon is not displayed in the upper-left corner of the LCD screen.

   ink low icon is displayed, you need to replace an ink cartridge 
before cleaning the print head; see page 41.)
