– when setting the paper tray –
When the paper tray is set in the copier, the tray set feeler [A] activates
the tray set sensor [B] and the tray lift motor [C] starts turning the worm
gear[D]. The rotation is transmitted to the tray lift gear [E] via 2 coupled
idle gears. The tray lift gear has 3 projections on its disc surface. As the
tray lift gear rotates, 2 of the 3 projections are caught by the coupling
hooks [F] of the limit feeler disc [G]. Then the limit feeler disc rotates
counterclockwise to pull the tray lift lever [H] via the bottom plate
pressure spring [I]. The tray lift arm [J] rotates counterclockwise to lift
up the tray bottom plate. At the same time, as the tray lift lever rotates,
the tray lock lever [K] rotates up by its own weight and is located at the
safety lock position against the tray lock pin [L]. When the limit feeler
disc activates the tray upper limit sensor [M], the tray lift motor stops.
