2-16 Phaser 6130 Color Laser Printer Service Manual
Theory of Operation
■ Paper Tray End Guide
The End Guide moves in toward the paper transfer direction to determine
the paper size.
■ Bottom Plate
The bottom plate is locked to the tray bottom when the tray is pulled out of
the paper feeder, and unlocked when the tray is installed in the paper
feeder. When unlocked, the bottom plate lifts the paper, pushing it against
the feed roller using spring tension.
Multiple Sheet Feed Prevention
The sheets loaded into the Paper Tray are occasionally stuck together along
the edges, which can cause a multiple feed or a jam. The sheets are fed by
the Feed Roller to a position between the Feed Roller and the Separator
Roller. Normally, when only one sheet is fed, both the Feed Roller and
Separator Roller rotate to allow the sheet to pass.
However, when two sheets are fed concurrently, only the Feed Roller rotates.
The Separator Roller is locked, allowing the upper sheet to pass, separated
from the lower sheet that is stopped by the friction with the Separator Roller at
rest.
The Separator Roller is pushed toward the Feed Roller by spring pressure,
and controlled by the Friction Clutch with which it is coupled.
