An image forming system includes an image forming apparatus and an information processing device. The image forming apparatus includes an apparatus display section which displays an image. The information processing device includes: a terminal display section which displays an image; a terminal transmission section which transmits remote input information to the image forming apparatus; a terminal reception section which receives remote output information from the image forming apparatus that received the remote input information; and a terminal controller which controls the terminal display section based on the remote output information. The terminal controller controls the terminal display section so as to display an image exhibiting the setting item information in a first region of the terminal display section and display an image exhibiting the related information in a second region of the terminal display section.

A conveyance apparatus includes a separation unit configured to separate and convey a sheet, a detection unit configured to detect a height-direction deformation of the sheet passing through the separation unit on a downstream side than a sheet-conveying position of the separation unit in a conveyance direction of the sheet, and a control unit configured to stop the sheet conveyed by the separation unit if the detection unit detects the deformation of the sheet.

A system and method are provided for implementing more efficient printing in image forming devices by providing a user-interactive scheme for delaying printing of individual user-requested print operations when an individual image forming device to which a specific user-requested printing operation is directed is determined to be in a power saving mode. The disclosed system and method may determine whether a requested image forming device is in a power saving mode at the time that a user requests an image forming operation and automatically present to the user a formatted user interface page on a display at the user workstation. The formatted user interface may provide the user with an option to direct the image forming device to delay (hold) executing the requested image forming operation until some additional condition is met.

Provided is an image-forming device that can execute operations that do not use a document-reading unit even when abnormality in a light source is detected in the initial operation at startup. The image-forming device includes a document-reading unit, and together with being able to execute image-forming operations that use the document-reading unit, is able to execute image-forming operations that do not use the document-reading unit. The image-forming device includes a light-source-abnormality-detection unit that executes a light-source-abnormality-detection operation, and when an abnormality in the light source is detected by the light-source-abnormality-detection operation that is executed at startup, stores the startup signal level that is outputted in a light-source-abnormality-storage unit as light-source-abnormality information. The image-forming device performs normal startup in which all image-forming operations can be executed regardless of the detection results of the light-source-abnormality-detection operation.

An image forming apparatus includes an output unit to which a recording medium on which an image has been formed is output, the output unit including an output unit body, and an extension portion that is disposed on the output unit body so as to be extendable from the output unit body in an output direction of the recording medium, the extension portion including a handle portion that is recessed in a direction away from a back surface of the recording sheet so as allow a finger to be hooked in a direction in which the extension portion is extended in the output direction of the recording medium, the back surface being a surface that is in contact with the output unit body, and a protrusion that protrudes toward the back surface of the recording medium from the extension portion.

An optical writing device and an image forming apparatus incorporating the optical writing device. The optical writing device includes two or more light sources, a pixel clock generator to measure a scanning speed of one of the two or more light sources and generate a pixel clock of a cycle corrected according to the measured scanning speed, a pulse data generation and output unit to generate pulse width data and shift data for the pixel clock generated by the pixel clock generator to output the generated pulse width data and the generated shift data for each one of the two or more light sources, and a plurality of image pulse generation and output units to generate an image pulse. In the optical writing device, the plurality of image pulse generation and output units are supplied with the pixel clock in common.

An image forming apparatus is provided. The image forming apparatus includes a network interface unit which is connected to a host device in which a manager program is stored, a printing unit which performs a printing job, a storage unit which stores a management information base (MIB), and an agent program, and a control unit which communicates with the host device using a Simple Network Management Protocol (SNMP). If an application is newly installed, the control unit updates the MIB. Therefore, it is possible to easily add, modify, or delete a management object (MO).

An automatic document feeder (300) includes a housing (301), conveyance roller pairs (313 to 317), and a pressure releasing mechanism. The housing (301) is openably/closably attached to a main body of an image forming apparatus. The conveyance roller pairs (313 to 317) pinch an original document sheet with pressure and feed the original document sheet. The pressure releasing mechanism detaches one rollers (313b to 317b) of the conveyance roller pairs (313 to 317) from the other rollers (313a to 317a) in conjunction with an operation of opening the housing 301 against the main body.

An optical scanning device is provided with a housing, a plurality of laser light sources, and a substrate. The laser light sources are attached to a side wall of the housing in a state wherein three terminals are protruding outward. The substrate is disposed to face an outer surface of the side wall of the housing. The laser light sources include: a first laser light source having a predetermined angle with respect to the substrate; and a second laser light source having a symmetrical angle to the angle of the first laser light source with respect to the substrate. In the first laser light source, only one of the three terminals is bent in the direction to be separated from other two terminals, and the second laser light source is disposed by inverting 180° a laser light source having a configuration same as that of the first laser light source.
