CAUTION:
When the Print Head Assembly is to be replaced,
the Head must first be cleaned. Otherwise air bub-
bles and clogged ink will prevent proper printing.
CAUTION:
Avoid touching, knocking or rubbing the nozzle
face of the Print Head Assembly.
CAUTION:
Each Print Head Assembly has a “rank” that has a
major effect on the ejection of ink. Entering a
wrong rank will adversely affect the life of the
head and the emission of inks. “Rank” is
inscribed on the print head assembly (see dia-
gram on right). The value to be input is a 5-digit
number.
