• The document feed section consists of the document pick-up roller, document feed roller, as well as the document separation roller, and is
directly driven by the document feed motor.
• When the start key is pressed, the document pick-up roller lowers to press the original, and the original is taken up and fed in. The original
is transported to the registration roller by the document pick-up roller and document feed roller.
• After the take-up and feeding sequence, the document feed motor is rotated backward, which raises the document pick-up roller.

• Timing at which to start transporting the original is controlled using the registration motor.
• The original is pressed against the registration roller and registration roll. This forms a loop in the original to thereby correct any skew in the
original.
• Mixed original sensors/1, 2/, and 3/ detect width of the originals in the mixed original mode.
