Q5 The I.V.700 is not printing even though
all of the LED's are working normally.
S5 Remove the four Phillips screws from the con-
troller housing and check the cable connec-
tion between the printhead and the control-
ler board. Check the continuity of the con-
troller to printhead cable. If the cable is de-
fective, replace it with cable 5750-192.
Q6 The I.V./700 is not printing and ALL
the LEDS are blinking. Why?
S6 A short-circuit has occurred. To determine
whether the short is in the printhead or the
controller, disconnect the barrel plug con-
nector and the printhead connector at the
printhead.
Connect the barrel plug connector but DO
NOT connect the printhead. If the unit ini-
tializes normally, replace the printhead (P/N
5750-199). If the unit does not initialize
normally, replace the controller (P/N 5750-
201 for a European model and 5750-202
for an Asian model).
