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

Recalibrates the home position of the printhead carriage. If the 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.

Measure Media Width

Measures the width of the media.

New Carriage

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

Prime Bars

Prints a wide-swath version of the prime bars.
