摘要:
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.

An information processing device is provided where in communications between the information processing device and another information processing device, the transmission rate of a communications interface of the information processing device is automatically set in accordance with a transmission rate at which the communications interface of the other information processing device is operable, for communications. A printer device holds a USB driver information managing table and/or a USB hardware information managing table which are lists of information related to a driver and/or hardware of a USB interface. The printer device obtains, from the host PC, printer device USB driver/hardware information which is information on a driver and/or hardware of a USB/IF of the host PC. The printer device checks a communications mode in which the USB/IF of the host PC is operable by comparing the printer device USB driver/hardware information and the USB driver information managing table and/or USB hardware information managing table. In accordance with results of the checking, the printer device determines a communications mode for the USB/IF of the printer device.

摘要:
In an apparatus to be controlled 20 such 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 controlled 20 itself and a change in the connection situation of an attached device 30 (S201: YES), identification information corresponding to the changed specification is extracted (S205) and the extracted identification information is set as identification information to be transmitted to the controlling apparatus 10 (S206). The identification information having been set is transmitted to the controlling apparatus 10, and the controlling apparatus 10 controls the apparatus to be controlled 20 having 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.
摘要:
Paper (41) on which a first reference image (31) is formed in an image forming section (300), and a correction instrument (1) on which a second reference image (33) is formed, are placed at predetermined positions on an original platen (210). Reference images (31, 33) are read as an image for correction by an image reading section (200). An error in the image reading section (200) is measured based on the second reference image (33) of the correction image. The first reference image (31) of the correction image is used to remove the error in the image reading section (200) from the measured error, resulting in an error in the image forming section (300).
