An example image forming apparatus includes a main body, a toner refilling portion, and a controller. On the main body, a development cartridge is mounted. The toner refilling portion is connected to the development cartridge and a toner refill cartridge inserted through a communicating portion of the main body and thus receives, from the toner refill cartridge, authentication information obtained from the toner refill cartridge, thereby adjusting a toner inflow from the toner refill cartridge to the development cartridge. A controller determines whether to allow a toner refill using the toner refill cartridge based on the authentication information obtained from the toner refill cartridge and authentication information obtained from the image forming apparatus and controls the toner refilling portion according to a determination result.

Provided is a finisher including a post-processor and an online suppliers. The post processor including a binding path, a binding unit to perform any one or combination of processes of a saddle stitching process and a folding process on a sheet-type medium on the binding path, and a manual supply slot to manually be supplied with the sheet-type medium towards the binding path. The online supplier to receive the sheet-type medium from an external device and supply the sheet-type medium to the binding path. A housing accommodating the post-processor and the online supplier and including an online supply slot to receive the sheet-type medium through the online supply slot from the external device.

An image forming apparatus to which a sheet treating apparatus is to be connected includes a communication device, having a serial port used for serial communication with the sheet treating apparatus and a parallel port used for parallel communication with the sheet treating apparatus, to communicate with the sheet treating apparatus, and one or more processors. At least one of the one or more processors operates to determine a communication method to communicate with the sheet treating apparatus based on configuration information representing a connection configuration of the sheet treating apparatus, and switch an operation of the serial port such that the serial port of the communication device is used in the parallel communication in a case where a determined communication method is a method in which the parallel communication is performed and the serial communication is not performed.

An image processing apparatus includes an image reader, an input operation unit including a display, an interface configured to receive, from an external medium, setting information for processing of an image read by the image reader, and a controller. The controller is configured to control the display to display a first setting screen for processing the image when the setting information is not received from the external medium and to control the display to display a second setting screen for processing the image when the setting information is received from the external medium. The second setting screen indicates that an operational setting designated by the setting information has already been set on the image processing apparatus.

An image forming apparatus includes a first processor configured to control a transporter that transports a sheet and a first image forming section that forms an image on the sheet transported by the transporter, and a second processor configured to control a second image forming section that forms an image on the sheet transported by the transporter. The first processor and the second processor are contained in a single housing. The first processor is configured to perform transport preparation for transporting the sheet at the transporter and receive, from the second processor, a completion notification corresponding to a preparation command, for performing image formation preparation in the second image forming section, transmitted to the second processor via an inside of the housing, and subsequently cause the transporter to transport the sheet and the first image forming section to form the image.

Disclosed is an image forming system including: an image forming apparatus; and an operation unit communicating wirelessly with the image forming apparatus. The operation unit includes a touch panel display, a first memory temporality storing a first screen image and a second screen image related to the image forming apparatus, a second memory in which the second screen image is stored in advance. When the first screen image transmitted from the image forming apparatus to the operation unit is displayed on the touch panel display, if a first icon on the first screen image is touched, the position of the first icon is transmitted to the image forming apparatus. When the second screen image stored in the second memory is displayed on the touch panel display, if a second icon on the second screen image is touched, a command indicating the second icon is transmitted to the image forming apparatus.

An image processing apparatus includes an image reader, an input operation unit including a display, an interface configured to receive, from an external medium, setting information for processing of an image read by the image reader, and a controller. The controller is configured to control the display to display a first setting screen for processing the image when the setting information is not received from the external medium and to control the display to display a second setting screen for processing the image when the setting information is received from the external medium. The second setting screen indicates that an operational setting designated by the setting information has already been set on the image processing apparatus.

An image forming apparatus to which a sheet treating apparatus is to be connected, including: a communication device, having a serial port used for serial communication with the sheet treating apparatus and a parallel port used for parallel communication with the sheet treating apparatus, configured to communicate with the sheet treating apparatus, one or more processors. The at least one of the one or more processors operates to determine a communication method to communicate with the sheet treating apparatus based on configuration information representing a connection configuration of the sheet treating apparatus, switch an operation of the serial port such that the serial port of the communication device is used in the parallel communication in a case where a determined communication method is a method in which the parallel communication is performed and the serial communication is not performed.

An image forming apparatus includes the following: an image forming portion; a first metal side plate and a second metal side plate provided opposite each other with respect to the image forming portion; an antenna for communicating with external equipment; a housing including a top cover that is provided above the first metal side plate and the second metal side plate in a vertical direction, and a side cover that is provided on an outer side opposite to an inner side where the image forming portion is provided with respect to the first metal side plate, wherein the image forming apparatus further includes a support member provided on the first metal side plate, the support member including a housing support portion that supports at least one of the top cover and the side cover, and an antenna support portion that supports the antenna.

The image forming apparatus according to the present disclosures is configured to transmit, to a file server, an acquisition request for an updating data file at a time different from an access time, which is indicated by access time information of a setting file, by a particular time and update a content of the setting file by the acquired updating data file.
