Feed roller/vertical transport roller control

• The feed roller and vertical transport roller are rotated, which feeds media from the lower
feeder unit and conveys it further into the inside of the main body
1. The transport motor is energized to turn the vertical transport roller.
2. The media feed clutch is energized to turn the feed roller.
3. The media is fed in by the feed roller.
4. The media fed in by the feed roller is conveyed onto the synchronizing roller of the
main body by the vertical transport roller.
5. When the media feed sensor is activated and then the media is conveyed onto a
predetermined point in the media path, the media feed clutch is de-energized, thus
bringing the feed roller to a stop. The vertical transport roller thereafter takes
charge of conveying media further.
6. When the trailing edge of the last sheet of media moves past the registration sen-
sor, the transport motor is de-energized to bring the vertical transport roller to a
stop.
