CHAPTER 4. FIRST PAPER FEED SECTION
Mechanism
1.
Paper Feed Tray Mechanism
Dampers are fitted to both sides of the paper feed tray to ensure that it opens gently. The paper feed tray
set sensor checks that the paper feed tray is in place.
The horizontal print position is adjusted using the print drum so the paper feed tray does not move
sideways.
The paper detection sensor (reflective type) checks that paper is loaded in the paper feed tray.
The final sheet in the paper feed tray is susceptible to multiple paper feeding. The L.O. sheet is used to
prevent such occurrences.
The size of the paper loaded in the paper feed tray is detected by the paper width potentiometer and paper
size sensor.
The paper width potentiometer senses the paper width, while the paper size sensor determines the
paper orientation (portrait or landscape).
The gap between the front and rear pinch rollers on the pinch unit is adjusted automatically to suit the
paper width detected.
The correspondence between the measured size and determined size is shown in the table on next
page.
