Image Sensor Tests:
this submenu tests various functions of the Image Sensor. The
Image Sensor is the imaging device used to measure media and perform AutoSet
calibrations.
Visually Examine LEDs:
allows the operator to visually examine if each LED is
firing correctly. The control panel will indicate what LED should be operating at a
given moment.
Whitepoint:
tests the Image Sensor’s sensitivity to whitepoint readings.
Take a Picture of White Paper:
the Image Sensor takes a picture of the media
and then prints a 400% enlargement of what was seen. This option can help
identify a dirty lens.
Take Raw Picture of Dots:
prints a small pattern of dots and takes a picture, then
prints a magnified image of what was seen. This test is principally for checking
hardware functionality.
Take Enhanced Picture of Dots:
similar to above, but uses the printer’s refine-
ment algorithms to image and print the picture. This test is principally for check-
ing software functionality. Run the “Take Raw Picture of Dots” first to confirm
hardware functionality.
Color Sensor Tests:
this submenu tests various functions of the Color Sensor (also
called Photodiode). The Color Sensor is the imaging device used to perform color
linearization and color profiling.
Blackpoint and Whitepoint:
tests the Color Sensor’s sensitivity to whitepoint and
blackpoint readings.
Visually Examine LEDs:
allows the operator to visually examine if each LED is
firing correctly. The control panel will indicate what LED should be operating at a
given moment.
Test Cooling Fan:
allows the turning on or off of the fan over the color sensor.
