Cleaning the print heads
This section shows you how to start print head cleaning with the RESUME
button on the printer operation panel. For details about starting print head
cleaning with the printer driver, see the Windows Print Guide or the
Macintosh Print Guide.
■ Print head cleaning consumes ink, so perform print head cleaning only
after you notice a deterioration in the quality of printed pages or when
the Nozzle Check Pattern is abnormal. (☞ 97)
■ Before you begin, make sure both the printer and the computer are
switched on.
■ Print head cleaning is performed with the BJ Cartridges mounted in the
printer. Never remove the BJ Cartridges from the cartridge holder in an
attempt to clean them manually.
