Abstract: In a printing device, a controller is configured to perform: (a) writing; (b) printing; (c) determining; (d) conveying; (e) writing; (f) printing; and (g) writing. The (a) writing writes prescribed information to an information storage medium provided in a first print medium. The (b) printing prints a prescribed image on the first print medium. In response to determining in (c) that the printing quality of the prescribed image is not good for the first print medium, the (d) conveying conveys a continuous medium in a reverse direction, the (e) writing writes void information to the information storage medium provided in the first print medium, the (f) printing prints a VOID image on the first print medium after the (e) writing is performed, and the (g) writing writes the prescribed information to the information storage medium provided in a second print medium prior to performing the (f) printing.

Abstract: There is provided a printing apparatus, including: a casing having a discharge opening and a conveyance route; a roller; a driving source; a printing head; a scanner disposed at a downstream side in a discharge direction; and a controller. The controller is configured to, depending on a printing preparation command, detect a leading-end position of a sheet; determine whether a printing surface of the sheet includes an error position that is not suitable for printing; and convey the sheet until the error position reaches the downstream position from the printing head. Then, the controller controls the printing head to execute printing of an image on the sheet.

Abstract: An electronic apparatus including an input unit configured to separate image data into pixel blocks and serially input luminance data and color difference data of each pixel block as individual pieces of block data, respectively, a quantization unit configured to serially convert each piece of the block data into quantized data, an encoding unit configured to serially convert each piece of the quantized data into encoded data, a color generation unit configured to generate compressed color image data using the encoded data, and a monochrome generation unit configured to generate compressed monochrome image data using the encoded data by performing one of deleting particular pieces of encoded data corresponding to the color difference data from a data sequence of the encoded data generated through the conversion by the encoding unit, and replacing the particular pieces of encoded data with encoded data corresponding to monochrome color difference data.

Abstract: A copying apparatus is configured to repeat a first operation to scan an image on an original sheet along a first direction with changing a position of the first operation along a second direction perpendicular to the first direction, and generate pixel data of pixels of the image on the original sheet. Compressed image data is generated by compressing the pixel data within each of multiple sections divided in the first direction having boundaries extend in the second direction. The compressed image data is decompressed. A 90-degree rotation processing is applied to the decompressed image data in the unit of a band, which has a particular number of pixels in the first direction and extends along the second direction, to generate decompressed image data, Then, with use of the decompressed image data after rotation processing has been executed, the image is recorded on a recording sheet.

The motor driver includes: an excitation phase control unit; and a drive unit. The driver control unit includes: a motor driver power control unit; a drive control unit; a clock signal output unit; and an excitation phase storing unit. The excitation phase storing unit acquires an excitation phase at a time when the motor driver power control unit stops supplying electricity to the motor driver, and stores the acquired excitation phase as a suspension excitation phase.

In the closed circuit forming step, a closed circuit from one of at least two contacts in a telephone connection terminal of a communication apparatus to another one of the at least two contacts in the telephone connection terminal is formed. In the current detection step, a current flowing in the closed circuit, when the closed circuit is formed in the closed circuit forming step, is detected. In the determination step, it is determined that the telephone line is improperly connected to the telephone connection terminal when the current is detected in the current detection step.
