摘要： An image forming section forms images, which are transferred onto a primary medium. A medium cassette holds a stack of print medium. A remaining-medium detector detects the number of pages of remaining print medium held in the medium cassette. The image on the primary medium are transferred onto a print medium fed from the medium cassette. A controller changes a timing at which the image forming section forms the images, the timing being changed in accordance with the number of pages of remaining print medium. The timing is changed in such a way that the images are formed at greater distance intervals on the primary medium when the number of pages of the medium cassette in the medium cassette is equal to or less than a reference value than when the number of pages of the medium cassette in the medium cassette is more than the reference value.

摘要： An image recording apparatus includes a plurality of print engine aligned in a advance direction in which a transporting member transports a recording medium. A first one of the plurality of image-forming sections records a first detection pattern on the transporting member and a second one of the plurality of image-forming sections records a second detection pattern on the first detection pattern. A color shift detecting section detects the amount of color shift between the first and second ones of the print engines by measuring an intensity of light reflected by the first and second detection patterns. Based on the amount of color shift, a correcting section corrects a position of the image recorded on the recording medium. The detection pattern may be of different configurations, depending on the direction in which color shift occurs, i.e., traverse, advance, and oblique directions. The detection pattern includes a plurality of blocks aligned in a row, each of the plurality of blocks having at least one stripe.

摘要： A medium contraction amount calculating unit calculates a medium length contraction amount in a fixing process of a recording medium in first printing from a medium length before the fixing process and a medium length after the fixing process. A write timing setting unit has medium contraction amount distributing means which center-distributes time corresponding to the medium length contraction amount to print start timing and print end timing in the next and subsequent printing and sets image write timing in the next and subsequent printing of the recording medium on the basis of the distribution by the medium contraction amount distributing means. When the same image is printed onto both surfaces or onto the same surface, the positional change of the same image can be made inconspicuous.
