Abstract
A knockdown apparatus for a finisher includes a register tray, a paddle coupled to a rotatable shaft to compile a recording medium toward an end of the register tray, and a knockdown device, provided above the register tray, to rotate to apply a downward force to the recording medium while the recording medium is in the register tray to decrease a curl in the recording medium.
Claims15
A knockdown apparatus for a finisher, comprising:
- a register tray;
- a paddle coupled to a rotatable shaft to compile a recording medium toward an end of the register tray;
- and
- a knockdown device, provided above the register tray, to rotate to apply a downward force to the recording medium while the recording medium is in the register tray to decrease a curl in the recording medium.
A finisher, comprising:
- a main body having an input port to receive a recording medium and an output port to output the recording medium after a finishing operation is performed on the recording medium;
- and
- a compiler section to receive the recording medium transported from the input port along a path within the finisher and to output the recording medium to the output port, the compiler section including:
- a register tray to accommodate the recording medium for compiling,
- a paddle coupled to a rotatable shaft to compile the recording medium toward an end of the register tray, and
- a knockdown device, provided above the register tray, to rotate to apply a downward force to the recording medium while the recording medium is in the register tray to decrease a curl in the 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 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 rotates in the forward direction to compile the recording medium in a register tray of the finisher;
- and
- to control the driving source to rotate the rotatable shaft in one of the forward direction or a reverse direction to cause a knockdown device provided above the register tray to rotate to apply a downward force to the recording medium while the recording medium is in the register tray.
