Printer operation check
Performing a printer operation check (self test) can help you
determine whether the problem comes from the printer or the
computer. 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 paper is loaded in the sheet feeder.
c
Caution:
Use paper at least 182 mm (7.17 inches) wide; otherwise,
the print head will spray ink directly onto the platen
during the self test and smear any documents you print
afterwards.
