Values in NVRAM are used to determine if
printhead and wiper have contact or if the
printhead was parked on last power down. If
printhead and wiper are in contact, the printhead
warms first before moving the wiper.
The BLUE line traces what happens if printhead
was parked on last power down.
NOTE: Headtilt CAM will be engaged when the
printhead is in the PARKED (restrained) position.
The RED numbers indicate errors that may be
displayed at that point in the process.
