A connector unit includes a connector mounting member having a mounting hole, and a connector passed through the mounting hole and attached to the connector mounting member. The connector includes a terminal portion to which another connector is configured to be connected, and a hook portion engaged with an edge portion of the mounting hole. The connector mounting member includes a panel portion on which the mounting hole is formed, an extending portion extending from the panel portion along an inserting direction of the another connector with respect to the connector, and a regulating portion projected from the extending portion at a position abutting against or close to an end portion opposite to the terminal portion of the connector in the inserting direction. A distance between the regulating portion and the panel portion is shorter than a distance between the terminal portion of the connector and the end portion.

In a printing system capable of supplying a sheet of a job having undergone print processing by the printing unit of a printing apparatus to a post-processing unit capable of executing at least a specific type of post-processing among a plurality of types of post-processes, when the target job requires the specific type of post-processing, the printing apparatus is inhibited from executing print processing of the job without explicitly determining a sheet necessary for the print processing of the job by a user using a user interface unit. When the target job does not require the specific type of post-processing, the printing apparatus is permitted to execute print processing of the job without explicitly determining a sheet necessary for the print processing of the job by the user using the user interface unit.

A multi-functional scanner for attaching paperclips to a sheaf of papers, which includes a paperclip dispensing system for holding and dispensing paperclips, a paperclip clamping assembly adjacent to the paperclip dispensing system for retrieving paperclips from the paperclip dispensing system, a conveyor belt located adjacent to the paperclip clamping assembly for feeding a sheaf of papers to the paperclip clamping assembly, a control circuit for controlling the paperclip dispensing system, the paperclip clamping assembly, and the conveyor belt, and where the paperclip clamping assembly is configured to attach a paperclip onto the sheaf of papers on the conveyor belt.

In case of simultaneously performing a punching process and a finishing process other than the punching process in an image forming apparatus, in order to prevent an unnecessary (ineffectual) finishing process from being performed, an information processing controller unit of a multifunction peripheral performs control of permitting to set in combination a double-punching center setting and a bookbinding setting, and of prohibiting to set in combination a punch setting, other than the double-punching center setting, and the bookbinding setting.

An image forming apparatus includes a reader, a wait part, and a processor. The reader reads an image from a first sheet. In the wait part, the first sheet is made to wait. The processor is configured to make the first sheet wait in the wait part after the reading performed by the reader, and, after the first sheet is made to wait in the wait part, output the first sheet and a second sheet continuously. The second sheet records first information determined on the basis of an evaluation result obtained from evaluation of the first sheet.

A printing apparatus includes: a conveyor; an image recording device configured to record an image on a printing medium conveyed in a conveyance direction by the conveyor; a divider provided downstream of the image recording device in the conveyance direction and configured to divide the printing medium; a detector provided upstream of the divider in the conveyance direction and configured to detect a trailing end portion of the printing medium; and a controller causing the printing apparatus to: calculate a dividing position of the printing medium based on a length of the printing medium that is grasped by detecting the trailing end portion by the detector; convey the printing medium in a reverse direction by the conveyor to move the dividing position to a position of the divider; and divide the printing medium at the dividing position by the divider.

A post-processing apparatus is connected to an image forming apparatus that forms an image on a sheet. The post-processing apparatus includes a post-processor, a sensor, and a controller. The post-processor performs post-processing on the sheet. The sensor is provided in a space where the post-processor operates and provides an output based on a presence of a foreign substance in the space. The controller acquires a first output value from the sensor prior to the image forming apparatus forming the image on the sheet, acquires a second output value from the sensor after the image forming apparatus forms the image on the sheet and before the post-processor performs the post-processing on the sheet, and determines whether or not the foreign substance is present in the space based on the first output value and the second output value.

A sheet alignment apparatus includes a sheet leading-end aligning device, a sheet side-end aligning device. The sheet leading-end aligning device is configured to align a leading end of a sheet bundle in a sheet conveyance direction. The sheet side-end aligning device is configured to align a side end of the sheet bundle in the sheet conveyance direction and move the sheet bundle to a predetermined position. The sheet leading-end aligning device is configured to maintain contact with the leading end of the sheet bundle when the sheet leading-end aligning device retracts from a movement path of the sheet side-end aligning device along which the sheet side-end aligning device moves the sheet bundle to the predetermined position.

An image forming system includes: an image forming apparatus; a post-processing apparatus that includes post-processors corresponding to at least two post-processes and perform the at least two post-processes stepwise on paper on which an image is formed by the image forming apparatus; a setting receiver that receives post-processing settings corresponding to the at least two post-processes; and a hardware processor that determines whether or not the at least two post-processes are executable based on the post-processing settings corresponding to the at least two post-processes and that, in a case where it is determined that the at least two post-processes are not executable, when a post-processing setting corresponding to one of the at least two post-processes is a setting including numerical value input, provides notification regarding a numerical value input setting change in the post-processing setting corresponding to the one post-processing.

An image processing apparatus includes a processor configured to: acquire image information obtained by reading a folded sheet with an image reading device in a state where the folded sheet is unfolded; acquire first and second distances in the image information, the first and second distances being distances from first and second positions to a predetermined reference of the sheet, respectively, the first and second positions on a folding line of the sheet being separated by a predetermined distance; and detect an inclination of the folding line of the sheet based on the first and second distances.
