2.1.1.7 Hopper 5mm Down Mechanism
Hopper 5mm down is to improve the paper loading credibility and to
prevent the head of paper from being folded at the moment that the Paper
Load Roller picks up the top of the paper in the paper tray.

[Explaining the operation]
At the moment that Paper Load Roller rotates and picks up the top paper
on the paper pile, there is a timing that the loading of Paper Load Roller
touches both hopper and separation pad. At this time, since the head of
paper might be folded by the rotation of Paper Load Roller because of
different angles and locations of the separation pad and hopper, this
phenomenon is controlled by pushing the lifter 5mm down at the moment
that the paper is picked up.
