The sheets of paper are moved through the main section of the compiler by the entrance roll,
exit roll, paddle shaft assembly and sub-paddle assembly.
Drive is provided to these components by the transport motor and a system of gears and pul-
leys. Refer to

Compiler Entrance and Exit Sensors
The progress of paper through the main compiler is monitored by two sensors, (1) the entrance
sensor and (2) the compiler exit sensor.
The entrance sensor is actuated by the lead edge of the paper entering the finisher from the
horizontal transport. This signals the paper feed process to begin.
The compiler exit sensor is used to ensure that paper successfully moves through the paper path. If
the compiler exit sensor is not actuated within a pre-set time of the entrance sensor being actuated,
a paper jam condition is signalled and an error message appears. Refer to
