PAPER FEEDING SYSTEM

9.2.3 Separation of paper

The separation roller in this equipment works to

separate the sheets of paper being fed. The sep-

aration roller section consists of the feed roller,

separation roller, spring joint, etc. The feed roller

rotates in the direction of the white arrow (shown

belowinthegureatright)atthesametimingas

the pickup roller rotation when the feed clutch is

turned ON.

When two sheets of paper are transported (shown

above in the figure at right), the lower sheet is

braked by the separation roller and not transport-

ed any further and the upper sheet is transported

in the direction of black arrow since the frictional

force between two sheets is small.

(Example)

When only one sheet enters into the separation

roller section:

Since the transporting force of the feed roller is

greater than the braking force of the separation

roller, these two rollers rotate together to trans-

port the sheet to the registration roller.

When two sheets enter into the separation roller

section:

Since the transporting force of the feed roller

and the breaking force of the separation roller

are greater than the frictional force between two

sheets, the sheet A is transported in the direction

of the black arrow and the sheet B is braked by

the separation roller and is not transported any

further.
