Abstract: A post-processing device, includes a tray that accepts a carried sheet and places thereon; a post-processing unit that performs a post-processing to the sheet placed on the tray; and a controller that controls an operation of the post-processing unit. The controller that: obtains both of: a first sheet type specified by a user; and a second sheet type detected by a media detector that is installed on a sheet carrying path; and controls the operation of the post-processing unit based on the second sheet type when the first sheet type and the second sheet type are different.

Abstract: A post-process apparatus may include: a first operation portion that accepts a sheet conveyed from an image forming apparatus and performs a first operation based on a job involved with the sheet, a second operation portion that accepts a sheet manually inserted into the post-process apparatus and performs a second operation different from the first operation, and a control unit that determines timing to perform the second operation in accordance with a condition of the first operation performed.

Abstract: An image forming apparatus includes a temperature sensor detecting an operating ambient temperature of the polygon motor, and a controller controlling the polygon motor and the paper feed mechanism. If the temperature detected by the temperature sensor is equal to or greater than a preset temperature, the controller controls, before operation for giving a command to start image formation is performed, the polygon motor to rotate; increases, in response to the operation, a rotational speed of the polygon motor up to a rated speed; and controls the paper feed mechanism to start conveying a sheet of paper at a time when a period of time variable depending on the detected temperature has elapsed, the period of time being preset to be shorter as the detected temperature increases, in expectation of a time required for the rotational speed of the polygon motor to reach the rated speed.

Abstract: An image forming system comprises: an image forming apparatus and a post processing apparatus that performs a post process on sheets each carrying thereon an image printed by the image forming apparatus. In the image forming system, a sheet feeder feeds sheets of a job to be post-processed to a post processing position; a timing judger judges which is before/after, the first timing to finish feeding the last sheet of the job to the post processing position, or the second timing to finish making preparation for a post process; a delaying time calculator calculates a post process execution delaying time that is a time difference between the first timing and the second timing; and a sheet feed controller controls sheet feed timing of the top sheet of a following job by using the calculated post process execution delaying time, if the second timing is after the first timing.

Abstract: Whether it is a double-side original mode is determined. When it is the double-side original mode, whether it is two-in-one printing mode is determined. When it is two-in-one printing mode, sequential reading mode is set. When it is not two-in-one printing mode, whether it is double-side printing and two-point stapling mode is determined. When it is double-side printing and two-point stapling mode, sequential reading mode is set. When it is not double-side printing and two-point stapling mode, whether it is booklet mode is determined. When it is booklet mode, alternate reading mode is set. When it is not booklet mode, concurrent reading mode is set.
