CHAPTER 4: FIRST PAPER FEED SECTION
[ 4 - 3 ]
2. Paper Feed Tray Elevation Mechanism
The presence of the paper in the paper-feed tray is detected by the paper-detection sensor.
When the paper is detected on the paper feed tray, and the Start key is pressed for a printing job, the elevator
motor makes the paper feed tray to elevates up to the upper limit position.
RZ3 series machines have two upper limit sensors, A and B. Which one of the two sensors is active depends
on the Paper feed pressure lever position. RZ2 series have only one upper limit sensor, which is sensor-B.
When the paper runs out from the paper feed tray, the feed tray comes all the way down to the lower limit
position, which is detected by the lower limit sensor.
Paper feed tray can be lowered when needed by pressing the green colored Paper feed tray button. Releasing
the finger from the button in less than 0.7 seconds will allow the try to come all the way down or until the button
is pressed again. If pressed over 0.7 seconds, the tray moves down only while the button is pressed.
