5.4 SEPARATION MECHANISM

[G]
UP
DOWN
The separation plate [A] is in contact with the upper separation roller [C]
due to the spring [B]. This is to prevent multiple paper feed.
As the lower separation roller [D] does not turn clockwise due to the one
way clutch bearings [G] provided on both right and left separation levers [E],
the sheets are separated and a sheet of paper is fed to the second feed roll-
ers. When 2 sheets of paper are fed, brake force is applied to the lower
sheet of paper.
The pressure between upper and lower separation rollers can be adjusted
in two steps by changing the right and left separation pressure adjusting lev-
ers [F].
