c. Multi-feed prevention mechanism

When feeding from the cassette, the printer uses the separation roller to prevent multi-feeding.

Normally, the separation roller is imparted with a rotational force opposite to that of the feed

roller. However, since the separation roller is equipped with a torque limiter, it rotates with feed

roller 1 by transmission of its rotational force via the transported paper. On the other hand, if

multiple sheets of paper are picked up, the low friction force between the sheets of paper result

in a weak rotational force being transmitted to the separation roller from feed roller 1.

Consequently, the separation roller’s own rotational force separates the extra sheet.
