Epson STYLUS SCAN 2500 User Manual page 227

Compare the quality of the printed check page with the
sample shown below. If there are no print quality problems,
such as gaps or missing segments in the test lines, the Stylus
Scan itself is functioning properly and your problem may lie
in the software settings, application settings, the interface
cable (be sure to use a shielded cable), or the computer.
The above sample is in black and white, but the actual check page prints in color
(CMYK).
If the check page does not print satisfactorily as shown below,
there is a problem with the Stylus Scan. If any segment of the
printed lines is missing, it could indicate a clogged ink nozzle
or a misaligned print head.
The above sample is in black and white, but the actual check pattern prints in color.
