Duplex Stacking - Ricoh FT5540 Service Manual

14.3 DUPLEX STACKING

Basic Operation
Paper is stacked in the duplex tray, which consists of the duplex delivery tray [A] and the
jogger unit [B].
The duplex delivery tray transports paper from the fork gate unit to the jogger unit. The duplex
delivery tray is ribbed to achieve precise stacking of paper in the duplex tray.
The jogger unit consists of a drive motor [C], jogger fences [D], duplex settlers [E], a
positioning roller [F], and duplex stoppers [G]. All these components work together to
achieve proper stacking of paper in the duplex tray.
When the Start key is pressed, the CPU reads the cassette paper size coding and the jogger
fences are positioned 15 mm from either side of the copy paper. As paper enters the duplex
tray, it is positioned under the duplex settlers. The positioning roller (made of sponge) rotates
and pushes the paper up against the duplex stoppers to correct paper skew. The positioning
roller is then lifted, and the jogger fences move inwards to square the stack every time a sheet
enters the duplex tray.
