An information processing system includes a server including a memory that stores a registered feature value of data and first circuitry, and an image processing apparatus connectable via a network to the server. The image processing apparatus includes second circuitry to extract a feature value from data and transmit the feature value to the server. The first circuitry receives the feature value transmitted from the image processing apparatus, outputs an output setting depending on whether the received feature value matches the registered feature value in the memory, and transmits the output setting to the image processing apparatus. The second circuitry receives, from the server, the output setting associated with the feature value, and instructs an image forming device to form an image based on the output setting.

Information processing system, image processing apparatus, information processing method, and recording medium for using stored featured values to form an image

A reading device including a position reference member having a reference pattern having a line extending along a first direction of the position reference member, the position reference member movable in a second direction orthogonal to the first direction; a reader including a plurality of sensor chips arranged along the first direction, each of the sensor chips having a length defined by a plurality of pixels; and circuitry. The circuitry is configured to detect the reference pattern of the position reference member using the reader; determine coordinates of at least two sensor chips in the second direction, based on the detected reference pattern of the position reference member; and correct a position of a reading target in the second direction based on the coordinates determined for the at least two sensor chips of the reader in the second direction.

A reading device includes a position reference member and a reader. The position reference member has a reference pattern that includes a line extending in a prescribed direction. The position reference member is configured to relatively move in a direction orthogonal to the prescribed direction. The reader includes a plurality of sensor chips, each of the sensor chips including a plurality of pixels. The reference pattern corresponds to each of the sensor chips of the reader.

Reading device, image forming apparatus, reference pattern reading method, and storage medium storing program code

An image reader includes a reading device to read an image on a recording medium, a first conveying roller pair upstream of the reading device in a conveyance direction of the recording medium, a second conveying roller pair downstream of the reading device in the conveyance direction, to hold the recording medium together with the first conveying roller pair to convey the recording medium, and a driver to drive the first conveying roller pair and the second conveying roller pair so that a relative relation between a reading position of the reading device and the recording medium held by the first conveying roller pair and the second conveying roller pair is constant. The reading device determines that the image read from the recording medium is effective in a period in which the relative relation is constant.
