◆ Dryer Test — runs the dryer heater assembly to test for cor-
rect operation.
◆ Print Image on Image Sensor — the printer prints a small set 
of lines which are scanned by the digital image sensor. Then 
the printer prints an enlargement of the image as the sensor 
captured it.
◆ Horizontal Dot Accuracy — for factory/service use only.
◆ Vertical Dot Accuracy — for factory/service use only.
◆ Isolation Print Test — for factory/service use only.
◆ Pod Test — for factory/service use only.
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.
