摘要： Switch units control ON and OFF of communication between a master device and slave devices. Signal levels of communication lines between switch units and slave devices are maintained at a predetermined level. A switch unit in a first stage is turned on and off by a first switch control signal. A switch unit in a second stage is turned on and off by a switch control signal generated based on a level of a communication line in the first stage and the first switch control signal. A switch unit in each of subsequent stages is turned on and off by a switch control signal generated based on a level of a communication line in a preceding stage and a switch control signal in a second preceding stage. A portion of ground short circuit is identified based on states of communication between the master device and the slave devices.

摘要： An image forming apparatus includes an image bearer, a driver, an image forming device, a sensor, and circuitry. The driver drives and rotates the image bearer. The image forming device forms a toner image on the image bearer driven and rotated by the driver. The sensor emits light to the image bearer and receives reflected light. The circuitry controls the driver and the image forming device to form a first toner image with a first color and a second toner image with a second color different from the first color. The circuitry controls the sensor to detect specularly reflected light and diffusely reflected light from the first toner image and the second toner image. The circuitry calculates an amount of misalignment of the first toner image and the second toner image based on a value of the specularly reflected light and a value of the diffusely reflected light.

摘要： An image forming apparatus includes an image bearer, an image forming unit, a toner image detecting unit, and a detection processing unit. The image bearer is configured to bear a toner image. The image forming unit is configured to sequentially form groups of pattern images for a plurality of colors in a sub-scanning direction of the image bearer, each of the groups including pattern images of the same color at a predetermined interval. The toner image detecting unit is configured to detect the pattern images formed on the image bearer. The detection processing unit is configured to recognize whether an interval between adjacent pattern images of the same color corresponds to a set interval, to exclude an image for which the interval does not correspond to the set interval among the detected pattern images.

摘要： An image capturing device includes an image capturing unit, a moving unit, a detector, and a determiner. The image capturing unit includes an optical transmission member; and a sensor capturing an image of the subject via the optical transmission member. The moving unit moves the image capturing unit in an optical axis direction of the sensor. The detector detects a contamination from first and second images. The first and second images are captured by the sensor when the image capturing unit is located at first and second positions in the optical axis direction, respectively. The second position is spaced away from the subject than the first position in the optical axis direction. The determiner determines that a contamination is deposited on the optical transmission member when a difference in the number of pixels in which a contamination is detected between the first and second images is less than a threshold.

摘要： An image scanning device includes a base part; and multiple image sensors each including a substrate, a line sensor including scanning elements arranged on the substrate, and a holder for holding the substrate. The base part holds the image sensors such that the scanning elements of an image sensor partly overlap the scanning elements of an adjacent image sensor in the main-scanning direction. The coefficients of linear expansion of the substrate and the base part are substantially the same; the holder and the base part are fixed together at a first fixing point; the holder and the substrate are fixed together at a second fixing point; and the distance in the main-scanning direction between the first fixing point and the second fixing point and the direction of the second fixing point with respect to the first fixing point are the same for all the image sensors.

摘要： A recording apparatus includes a carriage; a first head group including a recording head and disposed on the carriage; and a second head group including a recording head and disposed on the carriage adjacent the first head group in a staggered manner with respect to a sub-scan direction. The carriage is configured to move in a main scan direction in order to record an image on a recording medium. The recording apparatus further includes a forming unit configured to form plural test patterns including a first pattern formed by the recording head of the first head group and a second pattern formed by the recording head of the second head group. The test patterns are spaced apart from one another in the sub-scan direction. The position of the second pattern relative to the first pattern in the sub-scan direction is varied successively from one test pattern to another.
