Registration

The REGISTRATION test compensates for the actuation timing of the two
document sensors so that the document lead edge is correctly positioned
prior to the start of a scan. If the timing is correct, PASSED is displayed;
FAILED is displayed otherwise.
When the document is transported to the starting position, the lead edge
should be positioned within 0.25 inches (6.4 mm) of the center of the Platen
Window, as shown on the right.
If the lead edge is not positioned within the specification, perform the
REGISTRATION alignment.
1. Obtain a black, A (A0) piece of paper. The black paper test pattern
supplied with the scanner may be used.
2. Select REGISTRATION from the COMPONENT TESTS menu. The
REGISTRATION screen is displayed.
