摘要： An image processing apparatus, method and computer program product, wherein an initializing process of a scanner is performed in a short period of time when a return operation from a shutdown state is performed. A carriage of the scanner stays in a white level range when the main body is put in the shutdown state. Thus, the scanner immediately makes an automatic adjustment to its image reading level when the return operation from the shutdown state is started. The carriage detects an original position for a scanning operation while it moves to a standby position after the automatic adjustment is made. Thereby, the initializing process of the scanner is performed eliminating an operation of the carriage in which the carriage moves to the white plate range to read the white plate.

摘要： An image of a line of an original document is projected onto an arc of a rotating scanner drum. A plurality of scanning elements fixed to the drum scan the line by sweeping the arc. A timing disc is fixed to the drum which contains one set of timing marks indicating the angular position of the drum relative to the position on the line being scanned. A separate sensing head is provided for each scanning element to sense the timing marks and produce timing output signals. Each sensing head is adjustable to compensate for manufacturing inaccuracy in the relative position of the associated scanning element relative to the timing marks.

摘要： An image reading apparatus includes a carriage, a carriage detector, and a control unit. The carriage detector outputs a detection signal of the carriage when the carriage is at the home position, and outputs a non-detection signal of the carriage when the carriage is located closer to a document size reading position than a predetermined position between the home position and the document size reading position. The control unit moves the carriage to the home position when the image reading apparatus enters a sleep mode, keeps the carriage detained while performing initialization after the sleep mode is cancelled, and moves the carriage, upon receipt of a scanning instruction after the initialization is completed, toward the document size reading position in the case where the carriage detector outputs the detection signal of the carriage.
