When the Print Head Assembly is to be replaced, the Head must first be
cleaned. Otherwise air bubbles 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

assembly (see diagram on right). The value to be input is a 5-digit num-
ber.
