2.5.2 Paper Feeder

1. Size Switch Assembly
The Size Switch Assembly consists of four Paper Size Switches.
(The switches are directly mounted on the circuit board.) When the
Tray Size Actuator position changes, the ON/OFF combinations of
these switches change and the printer detects the paper size and
the paper tray.
2. Tray No Paper Sensor
From the Tray N/P Actuator position, the printer detects paper in the
paper tray.
3. Low Paper Sensor
If the paper in the paper tray gets low, the distance between the
Bottom Plate Assembly and the Low Paper Sensor is shortened.
That is, the Magnet behind the Bottom Plate Assembly gets closer;
the Low Paper Sensor detects the magnetism from the Magnet,
determining that the supply of paper is getting low.
4. Feed Solenoid
By controlling the rotation of the Feed Gear, the operation (rotation/
stop) of the Feed Roll Assembly is controlled.
5. Feed Roll Assembly
When the Feed Solenoid is activated, the Feed Spring force causes
the Feed Gear and Feed Idler Gear to mesh. The Feed Roll
Assembly then receives the driving force from the P/H Motor
Assembly and starts rotating, causing the Feed Roll to pull a sheet
of paper from the Paper Tray.
The Feed Gear has a notch that, after it rotates once, dislodges the
Feed Gear and the Feed Idler, causing the Feed Roll Assembly to
stop rotating. This mechanism ensures that only one sheet of paper
is pulled out.
6. Turn Roll Assembly
The Turn Roll Assembly receives the driving force from the P/H
Motor Assembly (via the Main P/H Assembly); it rotates and sends
the paper pulled out from the Paper Tray to the Main P/H Assembly.
