SCANNER TESTS

Scanner Calibration Reset

This option resets the scanner calibration values to factory default settings. This should be done after you

Note: Be sure the scanner glass and backing material are clean before performing this test.

Feed Test

This test performs a continuous feed test of either the flatbed scanner or ADF without producing any printed

settings. For a flatbed test, the scanner traverses the entire length of the flatbed.
