The tray registration motor [A] drives the tray registration rollers [B]. The tray feed
motor [C] drives the 1st relay rollers [D], 2nd relay rollers [E], the paper feed rollers
[F], and the paper pick-up rollers [G]. (See the arrows marked A in the diagram.)
To feed from tray 1, the tray feed motor turns counter-clockwise (as viewed from
the rear side), and the paper feed roller and paper pick-up roller in tray 1 rotate.
(See the arrows marked B in the diagram.)
To feed from tray 2, the tray feed motor turns clockwise, and the 1st relay rollers
turn. When the tray 2 feed clutch [H] is on, the paper feed roller and paper pick-up
roller in tray 2 also turn.To turn the 2nd relay rollers, the tray relay clutch [I] is
energized. (See the arrows marked C in the diagram.)
During feed from tray 1 (when the tray feed motor turns counter-clockwise), the tray
relay clutch stays off and the 2nd relay rollers do not rotate. This is to prevent the
tray feed motor from being overloaded. (When paper is being fed from tray 1, the
1st and 2nd relay rollers are not needed.)
The 1st relay sensor [J] is used to detect paper jams. The tray registration sensor
[K] detects paper arriving at the tray registration rollers.
When the next set of rollers (3rd relay rollers in the main frame) catch the paper,
the tray exit clutch [L] energizes to disengage the drive to the tray registration
rollers. This allows the tray registration rollers to turn freely, and only the 3rd relay
rollers feed the paper.
