Common portions of applications are extracted as common system service. A platform is formed by the common system service and a general purpose OS. A printer application, a copy application, and various applications are mounted on the platform. As a result, each software (application) corresponding to a printer, a copier, a facsimile device, and so on can be developed efficiently and the productivity of the apparatus as a whole can be improved.

Method, apparatus, and computer product for managing image formation resources

Method of and apparatus for image formation, and computer product

An information processing apparatus includes an acquiring unit for acquiring information stored in a memory of a printing device connected through a bidirectional interface, and a selecting unit for selecting a printer driver corresponding to the information acquired by the acquiring unit from a plurality of printer drivers on the basis of the information.

Information processing apparatus

A frame image () with 5-mm wide margins is formed on a paper sheet on the basis of the leading end and widthwise end positions of the paper sheet () detected by a contact image sensor (CIS) () in an adjustment mode. After that, this paper sheet () is circulated to a feed position via a circulating path () and paper convey path (), and the CIS () detects the frame image position formed on the circulated paper sheet and its paper end portion so as to detect errors from the 5-mm wide margins. Correction values which can cancel these errors are stored in a correction parameter storage unit (), and forming start timing control is made using these correction values upon forming an image in an actual job. In this way, an image forming apparatus which can detect the paper feed timing with high precision, can eliminate deterioration of the image position precision due to mounting errors and durability of components, and can always precisely adjust the image position is provided.

Image forming apparatus and image formation control method

An image forming apparatus is provided which includes a sheet containing section for containing sheets, a conveying member and a conveying path for conveying the sheets, at least one optical sensor that is arranged in the conveying path and has a light emitting element and a light receiving element for detecting presence or absence of a sheet on the conveying path, a driver for changing an amount of emitted light of the optical sensor, a sheet supply operation detecting section for detecting a supply operation of the sheets contained in the sheet containing section, and a control section for adjusting an amount of emitted light of the optical sensor according to an output of the sheet supply operation detecting section.

Image forming apparatus

An image forming apparatus has a CIS disposed in an area where a sheet passes in such a fashion that read pixels of the CIS are arranged in a direction perpendicular to the feeding direction of the sheet. A part of the read pixels (e.g., 1000 pixels) that corresponds to {fraction (1/7)} of all the read pixels are repeatedly read with a short period (TS) to detect the position of the leading edge of the sheet being fed. After waiting a predetermined period of time after the timing of detection of the leading edge position of the sheet, a laser beam is irradiated onto a photosensitive drum to start writing an image in the subscanning direction. Further, read pixels (e.g., 6000 pixels) that corresponds to {fraction (6/7)} of all the read pixels are repeatedly read with a long period (TL) to detect the position of the side edge of the fed sheet. Based on the detected side edge position of the sheet, the amount of deviation of the sheet is calculated to thereby correct the writing start position in the main scanning direction of the sheet.

Image forming apparatus that accurately detects sheet in the feeding direction, and method thereof

An information processing apparatus which outputs data to an electronic device. Information indicating a data processing ability of the electronic device is first obtained, whereupon data processing means is controlled so as to process the data output to the electronic device depending on the data processing ability indicated by the information so obtained.

Information processing apparatus and output apparatus

An information processing apparatus includes an acquiring unit for acquiring information from a printer connected through a bidirectional interface, and a control unit for controlling a display status of a virtual printer, which is displayed on a display screen and represents the printer, on the basis of the information acquired by the acquiring unit. An output apparatus includes a setting unit for setting an operating environment, and a changing unit for changing operating environment information set by the setting unit on the basis of information acquired from an information processing apparatus connected through a bidirectional interface.

The quantity of light of an optical sensor including a light emission portion and a light reception portion is adjusted through calculation before sheet detection is performed. In order to perform the light quantity adjustment, a voltage to be applied to the light emission portion of the optical sensor is obtained by performing calculation based on a relation between a voltage applied to the light emission portion before the adjustment and an output from the light reception portion before the adjustment. Then, it is judged whether the obtained voltage exists within a predetermined range and, if a positive result is obtained, the light quantity adjustment is ended. Further, a signal requesting the cleaning of the optical sensor is outputted in accordance with a value of the obtained voltage.

Sheet detecting apparatus and image forming apparatus equipped with sheet detecting apparatus

An information processing apparatus acquires identification information which specifies an interpreting program for interpreting a device control language, the specified interpreting program being operable in an external device connected to the information processing apparatus. It is discriminated whether a selected first control program corresponds to the device control language interpreted by the specified interpreting program. If it is discriminated that the selected first control program does not correspond to the device control language interpreted by the specified interpreting program, a second control program corresponding to the device control language interpreted by the specified interpreting program is selected from a plurality of control programs. Data is output to the external device using the first control program or, if it is discriminated that the first control program does not correspond to the device control language, the selected second control program.

Information processing apparatus with device control language based program selection

With a memory access control portion without being intermediated by control of a CPU controlling an entire drive control of a motor, velocity data for setting velocity of a motor step by step are read out from a velocity table memory, and data value read out from the velocity table are converted by a time conversion circuit to time data, and based hereon a phase switching signal to operate the motor is generated in a phase signal generating portion. In addition, outputting of next data is requested to a memory access control portion in every time data output of a time conversion apparatus and occurrence of access to a next memory table is urged.

Motor control apparatus

An information processing apparatus for communicating information with an information device. The information processing apparatus accesses virtual device image data representing an image of the information device, obtains status information representing a status of the information device from the information device through a bidirectional interface, and controls a display to display a virtual device image of the information device based on the accessed virtual device image data and the obtained status information. The virtual device image is a visual representation of the physical appearance of the information device in the status represented by the obtained status information.
