A mount apparatus to be mounted on a top surface, in a vertical direction, of a main body of an image forming apparatus configured to form an image on a sheet, includes a latch member extending toward the main body from a surface facing the top surface of the main body and being rotatable around a rotational axis extending in a direction along a direction orthogonal to the vertical direction, and a biasing member configured to bias the latch member in a predetermined rotation direction. The latch member is inserted into the main body through an opening that is provided on the top surface of the main body and is engaged with the main body by a biasing force of the biasing member in a state where the mount apparatus is mounted on the main body.

A sheet processing apparatus laminates a partially joined two-ply sheet and a sheet medium inserted in the two-ply sheet. The sheet processing apparatus includes a heat presser, an information acquisition device, and control circuitry. The heat presser heats and presses the two-ply sheet and the sheet medium. The information acquisition device acquires information on the two-ply sheet and the sheet medium. The control circuitry sets a fixing temperature of the heat presser in accordance with the information of the two-ply sheet and the sheet medium acquired by the information acquisition device.

A media punching and collating system includes a multi-source sheet intake mechanism, an accumulator, a punching die assembly and a discharge mechanism. The sheet intake mechanism is configured to pick and feed at least two different types of finished sheet media to the accumulator, which is positioned to receive the sheets from the sheet intake mechanism. The accumulator includes a sheet accumulating mechanism configured to sequentially gather and align a selected number of the sheets into a sheet lift. The punching die assembly is positioned to receive the sheet lift as a unit from the accumulator, and configured to punch holes in an edge of the sheets of the lift, after which the discharge mechanism discharges the punched lift.

A method of grouping sheet units, which belong together in sheet groups, a sheet stream comprising two superposed sheet units each by means of a grouping unit, a grouping unit for a sheet handling system, and a sheet handling system that allow a high processing speed and a high cycle efficiency of a sheet handling system are disclosed. A sheet unit can be held back in the grouping unit. Depending on whether the downstream subsequent sheet units transferred into the grouping unit belong to a sheet group, the held-back sheet unit can be released by itself and together with one or together with both downstream subsequent sheet units.

A printer that improves user convenience for rotating collation printing is provided. In a printer having a rotating collation function, multiple paper feed ports configured to feed paper, an acquisition unit configured to acquire a user request, and a setting unit configured to enable or disable the rotating collation function, the setting unit sets the rotating collation function to enabled when the acquisition unit acquires a user request to enable the rotating collation function, a first paper of a specified size that is fed in a landscape orientation and a second paper of the specified size that is fed in a portrait orientation are set in multiple paper feed ports, and paper feed port selection is set to automatic.
