Self testing
Printing a self test can help you det ermine whether the
problem comes from the printer or the computer.
If the self test prints satisfactorily, the printer itself is all
right and 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, 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 heads.
See “Problems and Solutions” for possible causes and
solutions to the problem, or go directly to "Cleaning the
Print Heads" later in this chapter.
To print 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.
cCaution:
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.
