A recording material processing apparatus includes a processing tray, a detecting unit, a stapling unit, an instructing unit, a control unit, a switching unit, and a notifying unit. The detecting unit detects recording material placed in the processing tray. The stapling unit executes a stapling process for the recording material placed in the processing tray. The instructing unit outputs a stapling process execution instruction. Upon receipt of the execution instruction in a state in which the detecting unit has detected a recording material inserted in the processing tray from an outside of a main body of a main body apparatus, the control unit cause the stapling process to be executed. The switching unit switches a position of the stapling unit among a plurality of positions. The notifying unit provides notification of a placement position of the recording material in the processing tray corresponding to each of the plurality of positions.

Each of the sheets is conveyed by a horizontal conveyance unit in a state of being overlapped with a next sheet from above. Each of the sheets is conveyed out of the horizontal conveyance unit in a state of being folded along a fold line with the fold line oriented upward, the fold line extending in a conveyance direction of the horizontal conveyance unit. An oblique conveyance unit receives the sheet from the horizontal conveyance unit and successively conveys the sheets in an oblique downward direction. A sensor is arranged to detect passage of the sheets at a position where steps pass. Each of the steps is formed by two sheets adjacent to each other diverted to the oblique downward direction by the oblique conveyance unit.

An example finisher includes a first portion extending in a vertical direction and including a height adjustment unit, a second portion extending from the first portion in a lateral direction and including a finishing unit to perform a finishing process, and a stacker to receive paper discharged from the finishing unit, the stacker extending in an opposite direction to the second portion in the lateral direction. The height adjustment unit is to adjust a height of the second portion from an installation surface and includes a base plate including a horizontal slot, a guide plate including an inclined slot, and a slide lever coupling the horizontal slot and the inclined slot.

A post-processing apparatus includes: a buffer unit that transports sheets such that at least two of the sheets are transported while being stacked on top of one another, the sheets being sent to the buffer unit from an image forming unit; and a compilation tray that is inclined with respect to a direction opposite to a direction in which the sheets are transported in the buffer unit such that the sheets, which are supplied from the buffer unit, are transported into the compilation tray from above the compilation tray and stacked onto a placement surface as a stack of sheets.

A printing apparatus includes a printing unit, a post-processing unit, and a controller. The controller includes a paper-type setting section configured to set a paper type of a paper feeding section, a storing section configured to store a plurality of paper types for which specific post processing is possible, and a control executing section. The printing output data includes paper type designation information, paper feeding section designation information, and post-processing designation information. When the post-processing designation information designates selection of the specific post processing and predetermined conditions including a condition that a paper type of second paper set by the paper-type setting section coincides with any one of the plurality of paper types stored in the storing section are satisfied, the control executing section controls the printing unit and the post-processing unit according to the paper feeding section designation information and the post-processing designation information irrespective of designation by the paper type designation information.
