GND
Heat enable
Inversion of output sequence of print
data lock output signal, black and color
heads locked OFF, ink optimizer head
and photo head locked ON.
Heat enable for odd black head and color
head nozzles and even ink optimizer and
photo head nozzles.
Heat enable for even black head and
color head nozzles and odd ink optimizer
and photo head nozzles.
