POWER ON
Values in the NVRAM are used to
determine if printhead and wiper have
contact or if the head was parked on
last power down. If printhead and wiper
are in contact, the printhead warms
first before moving. If the printhead
was parked, the printhead is warm
before moving to the print position.
The dashed line traces what happens
if the printhead was parked on last
power down.
The RED numbers indicate errors that
may be displayed at that point in the
mech init process.
