A communication controller controls non-contact communication with an external device via an antenna while at least one of first and second power is supplied. A first circuit electrically connects a first power supply to a communication node. A second circuit electrically connects a second power supply to the communication node. The first circuit includes a first electrical component configured to prevent second power from being supplied to a particular target electrically connected to the first power supply while the second power is supplied to the communication node. The communication controller communicates with the communication node in a certain data communication method while the second power is supplied to the communication node. In response to reception of electric power from the external device via the antenna, the second power supply supplies the second power to the communication controller, and supplies the second power to the communication node through the second circuit.

Communication apparatus configured to perform non-contact communication with external device

An image processing apparatus including a wireless communication unit, an image processing unit, and a controller configured to establish a wireless connection to perform wireless signal communication between the wireless communication unit and an external device, acquire a reception intensity of a wireless signal received from the external device via the wireless communication unit, determine whether the reception intensity is more than a threshold value, when determining that the reception intensity is more than the threshold value, control the image processing unit to execute an image processing instruction received from the external device via the wireless communication unit, and when determining that the reception intensity is not more than the threshold value, transmit an instruction to display a warning on the external device, to the external device via the wireless communication unit, without controlling the image processing unit to execute the image processing instruction.

Image processing apparatus and method for the same

A light scanning apparatus includes: a light emission unit emitting a first light beam and a second light beam; a motor; a rotary polygon mirror rotated by the motor, forming two scanning lines on a scan object at the same time; an optical sensor detecting the first light beam and the second light beam deflected by the rotary polygon mirror; a deviation measurement unit measuring a deviation amount of starting positions of the two scanning lines on the scan object based on a first detection timing at which the optical sensor detects the first light beam and a second detection timing at which the optical sensor detects the second light beam; and a motor control unit controlling rotation of the motor based on the second detection timing in a measurement non-execution period, and controls rotation of the motor without using the first detection timing in a measurement execution period.

Light scanning apparatus, image forming apparatus and computer readable recording medium

A method of adjusting line data is provided, where a dot pattern for one line is represented by dot data indicative of dot formation and blank data indicative of no dot formation. The method includes: determining whether X or more blank data are arranged consecutively, the X or more blank data including adjacent blank data adjacent to dot data on at least one side of the dot data, where X is an integer greater than or equal to one (X&#x2267;1); and converting Y consecutive blank data including the adjacent blank data into dot data if it is determined that the X or more blank data are arranged consecutively in the determining step, where Y is an integer greater than or equal to one and less than or equal to X (X&#x2267;Y&#x2267;1).

Method of adjusting line data and image forming apparatus

A forming-dot counting section counts a number of dots of a subject color based on dot pattern data of the subject color. An overlapping-dot counting section compares the dot pattern data of the subject color and the dot pattern data of at least one other color of which dots are formed prior to the subject color, and counts a number of overlapping dots of the subject color that are formed in an overlapping relation with the dots of the at least one other color. A calculating section calculates the amount of adhering toner of the subject color by subtracting an estimated amount of non-adhering toner from an estimated amount of adhering toner. The estimated amount of adhering toner is estimated based on the number of dots of the subject color. The estimated amount of non-adhering toner is estimated based on the number of overlapping dots.
