A post-processing apparatus includes a storing unit in which plural recording media are stored for performing post-processing and a transport member that transports a recording medium to the storing unit as a result of rotating while being in contact with a surface of the recording medium. The transport member includes a blade that comes into contact with a recording medium and a reinforcing portion that reinforces a strength of a portion of the blade that does not come into contact with the recording medium.

Provided is a stacker including a stacking shelf on which printed paper from a printer is received and stacked, a lifting and lowering mechanism that lifts and lowers the stacking shelf, and a stacker control unit that controls the lifting and lowering mechanism. The stacker control unit controls the lifting and lowering mechanism to lift and lower the stacking shelf to a first predetermined height corresponding to the printer at a receiving position for receiving the paper from the printer, and to lift and lower the stacking shelf to a second predetermined height corresponding to a sheet processing machine at a paper supply position for supplying paper to the sheet processing machine, the paper supply position being different from the receiving position.

The present application discloses a post-processing apparatus which performs a predetermined process after an image formation process performed by an image formation apparatus. The post-processing apparatus includes an ejection tray, which supports a sheet stack, in which sheets are stacked, and a curl prevention portion including a first tray cursor, which abuts an upper surface of the sheet stack on the ejection tray to prevent the sheet stack from curling. The curl prevention portion includes an angle changer, which changes an inclination angle of the first tray cursor with respect to the ejection tray. The angle changer sets the inclination angle to a first value when a number of sheets is a first number. The angle changer sets the inclination angle to a second value different from the first value when the number of the sheets is a second number different from the first number.

There are provided an ink jet printing apparatus and a color conversion processing device that can prevent the generation of offset and blocking and can stably jet ink. A first LUT in which a total amount of ink after conversion is large overall and a second LUT in which a total amount of ink after conversion is small overall are prepared as a look-up table (LUT) that is used in color conversion processing. A LUT to be used is selected according to the number of printed mediums. The first LUT is selected in a case in which the number of printed mediums is smaller than a threshold value, and the second LUT is selected in a case in which the number of printed mediums is equal to or larger than a threshold value.

A device and a method for feeding flat objects, in particular mail items such as envelopes or letters, in an upright position into a transport container. The device enables to achieve a high productivity and a high automation of the input of a plurality of flat objects and a safe guidance of the transport container by using a first transport device for transporting a transport container in a first transport direction, an input device for transporting flat objects along a second transport direction substantially opposite to the first transport direction, and a second transport device arranged below the first transport device for transporting the transport container in a third transport direction. Between the input device and the first and second transport device, a receiving device with a container receiver is arranged. The container receiver can be pivoted between a receiving position and a delivery position.

A system for presenting media sheets incudes a finisher output bin assembly. The finisher output bin assembly includes a translatable output floor, and a guide substrate coupled to the translatable output floor to guide the translatable output floor relative to the guide substrate in at least one coordinate direction. The finisher output bin assembly includes an output structure mechanically coupled to the translatable output floor to drive the translatable output floor relative to the guide substrate.

A printing device includes, in one example, a media output system including a mezzanine level including a plurality of media support members, the mezzanine level being intermediate to a floor level and a media output level; wherein the plurality of media support members move orthogonally relative to a print media path so that a number of finishing processes may be performed on print media accumulated on the number of media support members.

A page registration system may include, in an example, a media edge sensor to detect a location of an edge of a print media along a media feed path and in a direction non-parallel to the media feed path and a calibration sensor downstream of the media edge sensor to detect changes in the location of the edge of the print media in the direction non-parallel to the media feed path, and provide calibration data to the page registration system to correct changes in the location of the edge of the print media in the direction non-parallel to the media feed path.

A post-processing apparatus includes a storing unit in which plural recording media are stored for performing post-processing and a transport member that transports a recording medium to the storing unit as a result of rotating while being in contact with a surface of the recording medium. The transport member includes a blade that comes into contact with a recording medium and a reinforcing portion that reinforces a strength of a portion of the blade that does not come into contact with the recording medium.

A method for rapidly stacking and dropping sheets is provided. The method comprises receiving a plurality of sheets from a sheet delivery device onto a landing platform of a stacking and dropping apparatus. The method also comprises lowering the landing platform from an original upper position. Lowering comprises maintaining a drop height between the sheet delivery device and a stack of delivered sheets. The method also comprises sending a delay signal that comprises a command to delay the receiving of the plurality of sheets from the sheet delivery device. The delay signal is sent in response to a detection of a predetermined stack height of the stack of delivered sheets. The method also comprises sending a movement signal, immediately following the sending of the delay signal. The movement signal comprises a command to move the landing platform, such that the plurality of sheets are received by a catch tray unit. The method also comprises dropping, utilizing the catch tray unit, the plurality of sheets onto a sheet receiving device. The method also comprises returning, automatically, the landing platform to the original upper position. The method also comprises sending a resume signal, that includes a command to the sheet delivery device to resume sheet delivery. The delay signal, movement signal and resume signal are sent by a central processor component of the stacking and dropping apparatus.
