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.

An image reading apparatus includes a scanner unit including a first image reading portion configured to read an image of a first surface of a document through a first flow-reading glass, an ADF including a second image reading portion disposed on an opposite side of the first image reading portion across a sheet conveyance path and reading an image of a second surface of the document through a second flow-reading glass. The image reading apparatus further includes a gap forming member disposed on either one of the second flow-reading glass and a moving guide unit and abutting with another one of them. The moving guide unit is provided in the scanner unit and is urged by springs to be movable toward the second flow-reading glass.

An image forming system includes an image former; a reader that executes reading a document or a sheet; a post processor that applies post processing to the document or the sheet; and a controller. The controller controls the image formation, the reading and the post processing, judges the requested degree of importance of reading for a reading target on the document or the sheet, judges existence or nonexistence of an overlap between an execution timing of the reading and a timing of generation of vibration at the post processing, judges the necessity of a countermeasure to prevent the overlap from occurring with reference to the degree of importance of reading and the existence or nonexistence of the overlap, and controls the execution timing of the reading and the post processing to prevent the overlap from occurring when the controller determines that the countermeasure is necessary.

An image reading device, which is included in an image forming apparatus, includes a first transparent body, a second transparent body, a holding body, and a reading body. The second transparent body is disposed separated from and inclined at a predetermined angle to the first transparent body. The holding body holds the first and second transparent bodies. The reading body moves in a sub-scanning direction along the first and second transparent bodies. The holding body includes a flat face and a frame-shaped face. The flat face is contiguous to the first transparent body on a same plane and smoothly connected with the second transparent body. The frame-shaped face projects outwardly beyond the second transparent body facing the reading body. The reading body moves and contacts the first transparent body and the holding body, and moves with a gap relative to the second transparent body.

An image processing apparatus includes a switch section, a power supply section, an operation display section, an initialization control section, an image processing section, and a condition receiving section. The initialization control section causes the operation display section to start a first initialization processing when supply of a power supply voltage is started, and subsequently causes the image processing section to start a second initialization processing. The condition receiving section accepts an input of an execution condition. The operation display section includes a display part, a storage part, a display control part, and a condition setting part. The display control part causes the display part to display a screen after completion of the first initialization processing. The condition setting part stores an execution condition inputted via the screen in the storage part, and outputs the execution condition to the condition receiving section after completion of the second initialization processing.

An image forming apparatus includes a processor, a storage unit, a paper sheet feeder, an image forming unit, and a postprocessing unit. The postprocessing unit performs postprocessing on the recording sheet following image formation by the image forming unit. When a print/postprocessing job in which a plurality of copies is printed and postprocessing is performed on each copy is executed by the print-job execution unit, the postprocessing-position marking unit labels image data for at least the head page of the first copy with predetermined marks respectively in a position where postprocessing is to be performed and in a position where postprocessing is performable. The print-job execution unit, when executing the print/postprocessing job, performs control such that the first copy is printed without postprocessing, an image in which at least the head page has been labeled with the marks is printed, and the print/postprocessing job is temporarily halted.

An automatic document feeder includes: a recording-medium set unit, on which a recording medium is set; a recording-medium set detecting unit that detects whether the recording medium is set on the recording-medium set unit; a conveying unit that conveys the recording medium; a sheet-feeding cover section that constitutes part of the conveying unit and that includes an openable and closable sheet feeding cover; and a control unit that separately receives a power-on signal, which is output when a power source of an image forming device including the automatic document feeder is turned on, and an energy-saving return signal, which is output when a return is made from an energy saving state where a power source of part of the device is disconnected. When the power-on signal is received, the control unit performs an initialization operation to initialize each unit of the automatic document feeder.

An image forming apparatus includes a printer, a drawing data generating circuit, and a medium feeding circuit. The drawing data generating circuit generates, from print data, drawing data that causes the printer to execute a print job. The medium feeding circuit feeds the print medium to the printer. The medium feeding circuit executes: a first feeding stage in which the print medium moves to a specific position; and a second feeding stage in which the print medium moves from the specific position to the printer. The medium feeding circuit starts the first feeding stage after the drawing data is generated by the drawing data generating circuit when the image forming apparatus is in specific states, and starts the first feeding stage before the drawing data is generated by the drawing data generating circuit when the image forming apparatus is not in the specific states.

An image forming apparatus comprises a printing module, a transporting mechanism and a sorting module. The printing module prints data on media in order. The transporting mechanism transports the media past the printing module. The sorting module is disposed downstream of the transporting mechanism, and comprises an output mechanism, a rack and a driving pinion. The output mechanism transports the media out in a first direction. The rack is connected to the output mechanism. The driving pinion meshing with the rack drives the rack and the output mechanism to reciprocate in a second direction, different from the first direction, to sort the media into stacks. Thus, the sorting function can be achieved without providing a larger space and moving a discharge tray, and this is advantageous to the miniaturization of the image forming apparatus.

Job information being information concerning a processed job is managed together with an attribute that indicates whether the job information is printed or unprinted. Out of the managed pieces of job information of jobs, job information having an attribute indicating unprinted state is printed and the attribute of the printed job information is updated so as to indicate printed state. Out of the managed pieces of job information of jobs, when an instruction to print job information of a job corresponding to a logged-in user is received, the job information corresponding to the user is printed and the attribute of the printed job information is not updated.
