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.
