The document is transported into the document registration section by the ADF pick roller and ADF feed roller after
the feeding sequence.

When the document exits the document feed section, the motor (ADF registration) drives the ADF registration roller
to receive the document. A skew adjustment is made when the document passes between the ADF feed roller and ADF
registration roller. The sensor (ADF registration) detects the leading edge of the document while the ADF feed roller
continues to rotate to feed the document. The motor (ADF registration) continues to drive the ADF registration roller
to transport the document to the scanning section.
