You can test and calibrate the feeder sensors without taking off the covers of
the printer. If you have access to the Control Panel software on the host PC,
use the options in the "Test and Adjust" screen (see also the built-in help for
more information).
You can also test and calibrate the sensors via the control panel on the print-
er. See Appendix A - Menu Configuration, Service Menu>Paper Sensor Test
for more information. NOTE: The Exit sensor is on the DA95F only.
