Abstract
An paddle apparatus for a finisher includes a rotatable shaft and a paddle coupled to the rotatable shaft. The paddle is rotatable in a forward direction to compile a recording medium toward an end of a register tray of the finisher, and is rotatable in a reverse direction to apply a downward force to the compiled recording medium. An amount that the paddle is rotated in the reverse direction can be varied based on a height of the compiled recording medium in the register tray.
Claims15
A paddle apparatus for a finisher, comprising:
- a rotatable shaft;
- and
- a paddle coupled to the rotatable shaft,
- the paddle rotatable in a forward direction to compile a recording medium toward an end of a register tray of the finisher, and
- the paddle rotatable in a reverse direction, by a controlled variable amount determined based on a height of the compiled recording medium placed in the register tray, to apply a downward force to the compiled recording medium.
A finisher, comprising:
- an input port to receive a recording medium;
- and
- a compiler section to receive the recording medium transported from the input port along a path within the finisher and to perform a finishing operation with respect to the recording medium, the compiler section including:
- a register tray,
- a rotatable shaft, and
- a paddle coupled to the rotatable shaft,
- the paddle rotatable in a forward direction to compile the recording medium toward an end of the register tray, and
- the paddle rotatable in a reverse direction, by a controlled variable amount determined based on a height of the compiled recording medium placed in the register tray, to apply a downward force to the compiled recording medium.
A non-transitory machine readable storage comprising instructions that when executed cause at least one processor of a finisher to:
- control a driving source of the finisher, based on job information relating to a recording medium to be processed by the finisher, to rotate a rotatable shaft in a compiling section of the finisher in a forward direction such that a paddle coupled to the rotatable shaft compiles the recording medium in a register tray of the finisher;
- and
- control the driving source, based on the job information, to rotate the rotatable shaft in a reverse direction by a controlled variable amount based on a height of the compiled recording medium in the register tray, such that the paddle applies a downward force to the compiled recording medium.
