Checking the Print Head Nozzles

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.
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 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 before
cleaning the print head; see page 15.)
2. Load a few sheets of letter-size plain paper.
3. Press the Setup/Utilities button.
4. Press the l or r Photo/Options button to select Clean
Print Head . Then press the x Start button.
5. Press the x Start button again.
The Epson Stylus CX7800 runs a head cleaning cycle and
the processing icon appears on the LCD screen. Cleaning
takes approximately 30 seconds.
Caution:
Never turn off the Epson Stylus CX7800 while head cleaning is in
progress. You may damage it.
6. When cleaning finishes, make sure paper is loaded in the
Epson Stylus CX7800. Press the l or r Photo/Options
button to select Check Ink Nozzles . Then press the x Start
button.
7. If there are no gaps or lines, press the Setup/Utilities
button to return to the previous mode.
If there are gaps or lines, or the test patterns are faint, clean
the print head again.
