Cleaning The Print Head - Epson Stylus COLOR 670 Daily Use

The printer prints an operation check page including your
printer's ROM version information, the ink counter code, and a
nozzle check pattern. Below are sample printouts.

The above sample is in black and white, but the actual test prints in color
(CMYK).
If the nozzle check page does not print satisfactorily (for example,
if any segment of the printed lines is missing) there is a problem
with the printer. This could be a clogged ink nozzle or a
misaligned print head. See the next section for details on cleaning
the print head. For information on aligning the print head, see
"Aligning the Print Head" on page 50.
