摘要： PROBLEM TO BE SOLVED: To provide an inkjet recording method which can perform a complement printing of a defective nozzle without extending the printing time of an inkjet recording head.
SOLUTION: When there are a normal nozzle which can discharge an ink, and the defective nozzle which cannot discharge the ink in a block, the normal nozzle (called as a complement nozzle hereafter) being adjacent to the defective nozzle in the nozzle train direction is driven by corresponding to an image signal which corresponds to the defective nozzle, and thus, a dot complement for the defective nozzle is performed by this inkjet recording method. In the inkjet recording method, a total number of the ink discharging timings of the normal nozzle and the defective nozzle of nozzles in the block in a column agrees with the number of nozzles in the block.

摘要： PROBLEM TO BE SOLVED: To restrict deflection of the opposite side to the recording element substrate side of a supporting member although the deflection is brought about due to less expansion of the opposite side while the recording element substrate side expands as a result of a temperature difference between the recording element substrate side and the opposite face when the neighborhood of the supporting member is heated by heat of a recording element substrate generated at the time of printing. SOLUTION: An inkjet recording head 1 has the recording element substrate 101 where a plurality of recording elements are arranged on the substrate for discharging a recording liquid, and an ink supply port is set for supplying ink from a rear face of the substrate; an ink supply path for supplying the ink to the recording element substrate; and the supporting member 108 for holding and fixing the recording element substrate. A member having high rigidity and a smaller coefficient of linear expansion than that of the supporting member, is set at the supporting member. COPYRIGHT: (C)2004,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide an ink jet recorder in which temperature rise of a head can be suppressed by using a plurality of heads thereby lowering the use frequency per head, and degradation of an image (color shift) due to difference of thermal expansion between heads is suppressed by selectively using a head having a temperature as low as possible.
SOLUTION: A plurality of heads are prepared for each color of Bk, Y, M and C. Misregistration takes place between colors due to temperature rise during use and a circuit selecting a head of lowest temperature for each color is provided. Since a plurality of heads are employed for each color, they are used for complementing a nonejecting one. Since misregistration takes place between the complementing side and the complemented side due to difference of thermal expansion even in this case, a nonejecting nozzle to be complemented is located accurately by detecting the head temperature.

摘要： PROBLEM TO BE SOLVED: To provide an optical scanner capable of correcting scanning density in a main scanning direction in detail.SOLUTION: An upstream side laser beam detecting sensor 5 and a downstream side laser beam detecting sensor 6 output signals respectively when a laser beam passes between slits 11 and 12, and transit times are measured. In the downstream side laser beam detecting sensor 6, the angle of the slit 12 to a scanning direction can be varied by rotating a cam 14. A correction value computing part 23 determines a correction factor D from a pre-measured wavelength difference Δλ between an A beam and a B beam. A comparison part 24 calculates a difference ΔT by using the transit times Ta, Tb, and the correction factor D. A sensor rotational driving section 25 adjusts the slit 11 and the slit 12 to be exactly parallel by rotating the downstream side laser beam detecting sensor 6 so that the difference ΔT becomes a value 0.
