Epson Stylus 1500 Setup Information Manual page 32

The 360 dpi self test begins by printing in black ink on the
first and last lines of the first sheet of paper to measure the
page length.
Note:
If the self test does not begin, turn off the printer and repeat
step 2. You may need to hold down the buttons a few seconds
longer.
If you installed the optional Color Upgrade Kit, the self test prints
in color. If you want to run the 180 dpi self test, turn on the
printer while holding down the LF/FF button. The 180 dpi self
test always prints in black, even when the Color Upgrade Kit has
been installed.
3. To end the self test, press the Pause button. If there is paper
in the paper path, press the Load/Eject button to eject it.
Then turn off the printer. Otherwise, the test continues
until the paper in the sheet feeder runs out.
Caution:
c
Do not turn off the printer before pressing the Pause
button.
If the quality of the test output is not good, clean the print
heads as described in Chapter 3 of the Reference Guide. Then run
a demonstration page or another self test to check the print
quality. You may need to repeat these procedures several times
to fully solve the problem.
You may also need to calibrate your printer. After connecting
the printer to your Macintosh and installing the printer driver
as explained in the following sections, calibrate your printer
using the calibration utility program that came with your
printer. See Chapter 3 for instructions.
