摘要:
A sensor configuration and signal processing, which are not affected by a paper rise when a print pattern for auto head shading and density correction is read, are provided. A predetermined print pattern is printed with a plurality of heads, and the predetermined pattern that is printed is scanned with a sensor (110) to detect a density unevenness for the print pattern in each color on a nozzle basis. The sensor (110) comprises a light emitting element which emits a light including all light regions, R, G, and B, and a plurality of light receiving elements each of which receives R, G, and B lights, respectively. The plurality of light receiving elements are arranged in a main scanning direction. The print pattern printed by each head is read by the light receiving element for the complementary color light of the pattern and the light receiving element for a non-complementary color light of the pattern, and a change in density level in the nozzle column direction is detected based on the difference between the two outputs.

According to the type of paper sheet specified through an operation unit (111) by the user, the environmental temperature detected by a thermistor (110), and the spacing between the paper sheet and a paper sensor, detected by a lift height sensor (113), respectively, the correction values for the start and end positions where the printing heads start and end the printing in a horizontal direction are beforehand stored in a memory (112). Before printing, a CPU (104) detects the paper edge positions of the paper sheet on the basis of the output from a paper sensor (303), and reads the corresponding correction values from the memory (112) according to the type of paper sheet, the environmental temperature and the lift height. A window control unit (106) corrects the paper edge position with the correction values, thereby generating a window signal which controls the side margins of the paper sheet. In accordance with the window signal, a head control unit (105) controls the heads (103) for the respective colors to precisely determine printable regions extending horizontally from the printing start positions to the printing end positions.

An endless belt drive controlling apparatus includes an endless belt and its drive unit, a first detector that detects a belt mark, a second detector that detects a detected angular displacement error of an encoder generated due to a variation in a thickness of the endless belt, a first calculating unit that calculates a phase and a maximum amplitude of the endless belt at the belt mark based on the detected angular displacement error of the encoder thus obtained, and a second calculating unit that calculates a position of the endless belt at which the detected angular displacement error is a minimum from the phase stored in a nonvolatile memory.

Monitor circuits monitor junction temperatures of chips of driver ICs which drive a driving part of a recording/reproduction system. Comparison circuits compare the junction temperatures with respective arbitrarily set temperatures to output temperature flags as comparison results and are included in the driver ICs. A CPU monitors the temperature flags to confirm febrile states of the respective driver ICs, thereby performing a control so as to continue to drive an optical disk device when the junction temperatures of the chips of the driver ICs are lower than the set temperatures, and to suppress heat generation of the respective driver ICs when the temperatures are equal to or higher than the set temperatures. The so-constituted optical disk device can perform a control so as to effectively suppress heat generation before driving of the optical disk device is impeded by heat generation of the driver ICs which drive the recording/reproduction driving system of the device, thereby performing a fast and stable operation within allowable capacities of the driver ICs.
