Chapter 2 1 Paper Feed Section
S2-Y1540
1. Description
2. Operation
Paper feed section feeds the paper into the machine
after separating each sheet of paper by air knife.
This is done through the operation of the air suction
mechanism and the air blow duct mechanism.
Air blow duct mechanism blows the compressed
air to the paper from the front side to create some
gap between the papers. The separated paper is
transferred when the shutter solenoid and the feed
motor provided in the air suction mechanism are
turned ON.
3. Operation of Each Part
1. Level Sensor
<Operation>
• Detect the top of the paper on the feed tray
When the feed tray rises to the extent that the
actuator is lifted up by the paper, the sensor comes
to the “light blocked” state.
Once the topmost sheet of paper is detected, the
rising motion of the feed tray is stopped.
• Detect the low level of paper
The actuator comes down as the paper level gets
low until the sensor comes to the “light through”
state. Once the sensor comes to the “light through”
state, the feed tray rises until the sensor comes
to the “light blocked” state. “E02” (elevator error)
appears on the display if the topmost paper sensor
does not switch to the “light blocked” state within 10
seconds after the transmission of feed tray go-up
command.
