Abstract: PROBLEM TO BE SOLVED: To provide a recording apparatus, suitably guiding printing paper, and transporting the same at a designated distance from a head at a designated speed to perform high quality printing.
SOLUTION: In an ink jet printer 1, the printing paper P stored in a paper feed cassette 42 is transported by a pickup roller 11, a separating roller 12 and a reversing roller 14, and guided through a guide plate 16 to the vicinity of a transport belt 17. The printing paper P guided by the guide plate 16 is abutted at a very gentle angle about 24 degrees to the transport belt 17 and placed on the transport belt 17. The printing paper P placed on the transport belt 17 is further pressed to the transport belt 17 by a pinch roller 20, and transported with the whole of the back uniformly held on the belt to the recording position by a head part 31 to be recorded.

Abstract: PROBLEM TO BE SOLVED: To provide a method for driving a head and a printer using the method which generates a density jump in an as high density area as possible, makes the density jump to be visually less conspicuous even when the density jump is generated, and takes measures against a moire. SOLUTION: The method for driving the head 35 is adopted to the printer 5 which forms dots DT on a medium 27 to be recorded by hitting ink drops repeatedly, almost at the same time as conveying the medium 27 to be recorded, in a width direction of the medium 27 to be recorded almost perpendicular to the conveyance direction, and prints characters and images consisting of the dots DT. The dots DT adjacent to the medium 27 to be recorded almost in the width direction are hit to the medium 27 to be recorded with a phase shifted in the conveyance direction of the medium 27 to be recorded.
