In an apparatus to be controlledsuch as a USB-compatible peripheral device connected to a controlling apparatus such as a personal computer, when a specification change is detected such as a change in the apparatus to be controlleditself and a change in the connection situation of an attached device(S: YES), identification information corresponding to the changed specification is extracted (S) and the extracted identification information is set as identification information to be transmitted to the controlling apparatus(S). The identification information having been set is transmitted to the controlling apparatus, and the controlling apparatuscontrols the apparatus to be controlledhaving the changed specification, on the basis of the identification information. This controlling apparatus for controlling the apparatus to be controlled on the basis of the identification information for identifying the apparatus to be controlled adjusts easily to the change in the specification of the apparatus to be controlled.

Peripheral accessory specification identification and transmission

Paper () on which a first reference image () is formed in an image forming section (), and a correction instrument () on which a second reference image () is formed, are placed at predetermined positions on an original platen (). Reference images () are read as an image for correction by an image reading section (). An error in the image reading section () is measured based on the second reference image () of the correction image. The first reference image () of the correction image is used to remove the error in the image reading section () from the measured error, resulting in an error in the image forming section ().

Image position correcting method, image position correcting jig, and image formation device

A scan ID, which is operation identification information having been used for selection of an image reading condition or the like, is used for selection of a communication destination from among a plurality of host PCs having network-connection to a scanner relay apparatus. Information such as an image reading condition associated with the scan ID is sent to a host PC defined as a communication destination, and a scan command sent back from the host PC, whose protocol is converted, is sent to a scanner apparatus. Furthermore, image data sent back from the scanner apparatus is sent to the host PC.

Scanner relay apparatus and image reading controlling method

An immediate printing type image forming apparatus is provided of which the warm-up time is sufficiently shortened without causing any trouble to occur in the execution of image reading processing and/or image forming processing. The image forming apparatus is configured to determine a time required to raise the current temperature of the surface of a heating roller in a fixing unit to a predetermined temperature and increase the duty ratio of a power waveform to be fed to each of a copy lamp and a motor driving a polygon mirror when the time required thus determined is shorter than each of a time required to increase the current light quantity of the copy lamp to a predetermined light quantity and a time required to raise the current rotational speed of the motor to a predetermined speed, thereby turning each of the copy lamp and the motor into respective predetermined condition before the elapse of the determined time required.

Image forming apparatus and initialization control method therefor

An apparatus according to the present invention includes a stepping motor (5) and a motor drive circuit (4) for first moving a lamp unit to hit the unit against a reference object opposite to an origin and then moving the unit toward the origin, a CPU (3) for measuring the distance through which the lamp unit is moved from the reference object toward the origin, and the CPU (3) for controlling the lamp unit so that the lamp unit stops at the origin according to the distance measured from the reference object.
