Calibrations
These calibrations are performed at the factory. If any of them
are detected as out-of-specification, a message is displayed on
the control panel, recommending that you perform the applica-
ble calibration:
◆ Head Height — re-homes the head height to the known
highest reference point, or if New Carriage was previously
selected (see below), recalibrates the known highest refer-
ence point
◆ Media Sensor — locates the platen to establish the “media
out” head height
◆ White Point — reads the white point reference chip in the
platen to establish a white point for the photo diode.
Home Head

printhead carriage will not return to the service station between
prints, select this option. Cycling the power off and on will also
run the Home Head function.

New Carriage
Reinitializes the head height so that it can be recalibrated (see
“Calibrations,” above.
