Self Testing - Epson Stylus COLOR 800 User Manual

Self testing

Self testing can help you determine whether the problem comes
from the printer or the computer.
If the self test results are satisfactory, this means that the
printer itself is all right and that the problem probably lies
in the printer software settings, application settings, the
interface cable (be sure to use a shielded cable), or the
computer itself.
If the self test does not print satisfactorily, this tells you
there is a problem with the printer. See "Problems and
Solutions" on page 10-7 for possible causes and solutions
to the problem.
To perform a self test, follow these steps:
1. Make sure both the printer and computer are turned off.
2. Unlock the wire clips on both sides of the interface connector
and remove the ground connector, if necessary. Then
disconnect the cable from the printer's interface connector.
3. Make sure that paper is loaded in the sheet feeder.
c
Caution:
Use paper at least 210 mm (8.27 inches) wide; for example
A4 size paper loaded short edge first. Otherwise, the print
heads will spray ink directly onto the platen. This may
cause any documents you print afterwards to be smeared.
