According to one embodiment, an image forming apparatus includes a detachable device, an antenna, and a control unit. The detachable device is attachable to and detachable from the own apparatus and includes a wireless tag. The antenna receives a wireless signal from the wireless tag if the detachable device is mounted. The control unit determines that the detachable device is mounted to the own apparatus based on the wireless signal received by the antenna.

If an image read by an image reading unit is formed by an image forming unit, a control unit synthesizes a first encoded image and a second encoded image with the image formed by the image forming unit to generate a synthetic image, the first encoded image representing encoded data where reading setting information used for the image reading unit to read the image is encoded, the second encoded image representing encoded data where forming setting information used for the image forming unit to form the image is encoded, the first encoded image being synthesized at a position where a direction in which the document is read by the image reading unit is specifiable, and the second encoded image being synthesized at a position where a direction in which the image is formed on the sheet is specifiable. The image forming unit forms the synthetic image on the sheet.

In a communication system, an image forming apparatus sends an address of a receiving section to an external device. The external device receives a selection of image data through plural thumbnails displayed on a display section, and wirelessly sends the selected image data to the image forming apparatus with the address. The image forming apparatus receives the selected image data sent with the address by the external device, and prints an image based on the selected image data. The image forming apparatus accepts a selection indicating whether a communication between the external device and the image forming apparatus is performed by a first communication system method or a second communication system method. The image forming apparatus performs sending and/or receiving the image data with the address by the first communication system method when the first communication system method is selected, and performs sending and/or receiving the image data with the address by the second communication system method when the second communication system method is selected.

A printing apparatus includes a receiving unit which receives print data, an operating unit which receives a print instruction from a user, a display unit which displays a password entry screen for receiving a password entry from a user, and a printing unit which receives a print instruction from a user through the operating unit and prints print data without accepting a password through a password entry screen if a password added to the print data is matched with a fixed password and print data to be printed if a print instruction from a user is received through the operating unit, if the password added to the print data is matched with the fixed password, and if the password received through a password entry screen is matched with the password added to the print data.

An image reader includes: a reading section reading a document; a document conveyance section being supported in an openable and closable manner with respect to the reading section; foamed synthetic resin members being supported on a lower surface of the document conveyance section; a document pressing plate being fitted to the document conveyance section with the foamed synthetic resin members in between; and height regulation sections being formed at the document conveyance section and being pressed by second platen glass with the document pressing plate in between, wherein the height regulation sections are located at positions overlapping with a region of the second platen glass when the document conveyance section is in a closed state.

Generally, a job management apparatus of the present embodiment which sends a print job to an image forming apparatus comprises a communication section and a controller. The communication section communicates with the image forming apparatus and a delivery apparatus configured to deliver a sheet printed by the image forming apparatus to a delivery destination. The controller calculates printing time relating to completion of execution of the print job by the image forming apparatus and first arrival time when the delivery apparatus reaches the image forming apparatus and enables the image forming apparatus to execute the print job at a timing when the image forming apparatus can complete the execution of the print job by the first arrival time.

An image forming apparatus according to the present invention causes an image forming portion to perform image forming processing based on a security job issued by an output-permitted user, in a case where an outsider-use-possibility calculated by an outsider-use-possibility calculation portion becomes equal to or smaller than a predetermined threshold value on the basis of information of a movement trajectory of the output-permitted user and also the output-permitted user has been detected in an output-process-start area. Accordingly, it is possible to enhance the convenience for the output-permitted user while ensuring the security of the output product based on the security job issued by the user.

Information apparatus and application software supporting printing over air or network are herein disclosed and enabled. The information apparatus may include one or more software components that include (1) a discovery component to discover a supported printer in a local area network (LAN) and to receive device information related to the printer (e.g., capability, language or format supported, identification) from the printer, and (2) a printing component to generate or obtain print data based on the device information received and to transmit the print data to the discovered printer. After establishing the connection to the LAN, application software (e.g., Internet browser, email, photos, documents) in the information apparatus may print digital content by using the discovery component to discover the printer in the LAN, and may use the printing component to obtain and transmit print data in a form that is acceptable to the printer for printing the digital content.

A sensor apparatus includes a photosensitive sensor, a cover, and a moving mechanism. The photosensitive sensor includes a first lens and a second lens which focus on a photosensitive element. The cover includes a first slit arranged on an optical axis of the first lens and a second slit arranged on an optical axis of the second lens. The moving mechanism is configured to move the photosensitive sensor and the cover relative to each other so that the second slit is arranged on the optical axis of the first lens.

In some examples, a supply component for a printing device includes a memory device comprising a plurality of corrective data to produce a corresponding plurality of color tables each customized for a respective media type of a plurality of media types, wherein a respective corrective data of the plurality of corrective data corresponds to nodes of a reference color table for the printing device that is able to accept the plurality of media types for printing. The respective corrective data includes a plurality of residual values to transform the nodes of the reference color table to a customized color table for use with a selected media type of the plurality of media types.
