Manual Media Sensor Calibration
The Manual Media Sensor Calibration procedure should be used in cases where the printer
continues to suffer from media sensing problems after performing or attempting to perform the
Auto Media Sensor Calibration.

the Printhead Carrier Assembly is latched down and the cover is closed.

continue to hold the button until the
STOP
light turns on; then release the button.
2. Remove all the material from the media sensor, close the Printhead Carrier Assembly, and
then press the
