Theory of Operation
Paper Exit Assembly
The paper exit assembly discharges the printed paper out of the printer,
sending it either to the standard output tray or to the optional stacker.
Exit motor assembly This motor drives the exit roller that conveys paper to
each output tray. If the optional duplex unit is installed, this motor also
reverses and inserts paper into the duplex unit.
Exit roller This roller transports the printed paper sent out from the Fuser, to
the standard output tray.
Output tray full sensor This sensor detects that the standard output tray is full,
using the stack full actuator.
Stacker exit gate This gate switches the paper transport path interlocking with
the stacker gate link. When the gate solenoid assembly installed in the
optional stacker operates, the stacker gate link is pushed down by the spindle
of the solenoid assembly. The gate blocks the normal paper output path and
switches the output direction to the stacker output tray.
