Abstract:
An image forming apparatus includes a processing circuit, a memory, a data reception circuit, a bus, and a transmission amount control circuit. The processing circuit concurrently executes a plurality of jobs including a fax job and a print job. The memory is used for a work area of the processing circuit. The data reception circuit stores the image data received via the communication network in the memory. The bus connects a plurality of modules including the processing circuit and the data reception circuit to the memory. The transmission amount control circuit reduces an amount of data transmission from the data reception circuit to the memory via the bus when the processing circuit executes the print job concurrently with the fax job, compared with a case where the print job is executed concurrently with any job other than the fax job.
Abstract:
An image processing apparatus includes bus, adding portion, image processing portion, and output processing portion. In the case where document sheet data as a processing target is monochrome image data, the adding portion outputs, to the bus, color image data obtained by adding, to the monochrome image data, dummy image data pieces for a plurality of colors each corresponding to a predetermined processing unit amount which corresponds to a part of the monochrome image data. The image processing portion performs image processing per data amount equal to or smaller than the processing unit amount and outputs the resultant data to the bus. The output processing portion outputs image data pieces for a plurality of colors included in the color image data processed by the image processing and acquired from the bus, in accordance with synchronization signals inputted for the respective image data pieces for the plurality of colors.
Abstract:
An image forming apparatus has a storage portion, a mechanism control portion, and a main control portion. The storage portion stores information as to the apparatus. The mechanism control portion controls the operation of a mechanical system in the apparatus. The main control portion performs a job related to a function of the apparatus by controlling the operation of individual constituent elements of the apparatus, and on detecting an error that prevents continuation of the operation of the mechanical system included in the job being performed, feeds the mechanism control portion with an instruction to interrupt the control of the operation of the mechanical system, stores in the storage portion uncompleted data of the job corresponding to the operation of the mechanism control portion left uncompleted as a result of the interruption, reboots itself, and restarts the job by using the uncompleted data.
Abstract:
This image forming apparatus includes: a plurality of sheet accommodating portions each including a sheet placement portion on which a sheet is placed; a lifting/lowering portion configured to lift and lower the sheet placement portion; an image forming portion configured to form an image on the sheet supplied from each sheet accommodating portion; and an engine control portion configured to control the image forming portion on the basis of inputted print data. The engine control portion causes the lifting/lowering portion to lift the sheet placement portion to a predetermined sheet feed possible position in response to reception of the type of the sheet, and after the image formation by the image forming portion is finished, the engine control portion causes the lifting/lowering portion to lower the sheet placement portion to a predetermined original position.
Abstract:
In an image processing device and an image processing system according to the present invention, a storage unit holds image processing jobs received by a job receiving unit. An authority information acquiring unit acquires authority information indicating authority that a user specified by a user specifying unit has with respect to the image processing job in the storage unit. Based on the authority information acquired by the authority information acquiring unit, a processable job extracting unit extracts an image processing job for which the user specified by the user specifying unit has authority to delete or execute from among the image processing jobs in the storage unit. A display unit displays the image processing job extracted by the processable job extraction unit.
Abstract:
An inkjet recording apparatus includes a recording head, a reading device, and a controller. The recording head ejects ink to form a sample image on a sheet. The reading device reads the sample image to generate read image data. The controller determines a start timing of reading processing by which the reading device reads the sample image. The controller causes the reading device to start the reading processing at the start timing. The controller determines a drive condition of the recording head based on the read image data.
Abstract:
In absence of a paper feed source matching paper information specified in settings that are input by a user for a job to be executed, permission information associated with the user may not permit use of a manual feed tray as a substitute paper feed source. Upon completion of the job executed in response to selection of a forced execution key, a forced execution determination section determines whether or not an execution number exceeds a predetermined threshold. The execution number indicates how many times a job has been executed in response to selection of the forced execution key. When the execution number exceeds the threshold, a permission information updating section updates the permission information associated with the user so as to permit use of the manual feed tray as the substitute paper feed source.

Abstract:
An image forming apparatus (1) includes an image forming section (6), a plurality of recording paper trays (7a to 7n), storage (5), and a paper feed stage selecting section (12). The image forming section (6) performs advanced printing based on a paper profile. The paper feed stage selecting section (12) selects a recording paper tray (7) from the recording paper trays (7a to 7n) from which recording paper is to be fed to the image forming section (6) based on a printing instruction. When a specific paper profile is not associated with the selected recording paper tray (7), the paper feed stage selecting section (12) notifies the image forming section (6) of a manual setting and causes the image forming section (6) to perform simple printing.
Abstract:
An image forming apparatus includes a medium storing part storing mediums, a sheet feeding part feeding the medium from the medium storing part, an image forming part forming an image to the medium, a residual quantity detecting part, a storage part, and a residual medium estimating part. The residual quantity detecting part detects a residual quantity of the mediums stored in the medium storing part as a relative residual quantity with regard to a maximum storing quantity of the mediums in the medium storing part. The storage part stores maximum storing number of the mediums corresponding to the maximum storing quantity of the medium storing part. The residual medium estimating part calculates number of estimated residuals of the mediums stored in the medium storing part on the basis of the relative residual quantity detected by the residual quantity detecting part and the maximum storing number stored in the storage part.
