Epson Stylus Scan 2000 Manual page 74

The Stylus Scan prints an operation check page including its ROM
version information, the ink counter code, and a nozzle check
pattern. Below are sample printouts.
Good sample
Print head needs to be cleaned
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 Stylus Scan's printer function. 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 136.
