摘要： An image forming apparatus including: (a) a feed mechanism including a motor and a feeder moved by the motor for feeding a medium; (b) a recording head for ejecting an ink toward the medium to form an image; (c) a feed controller for controlling the motor so as to move the feeder to a target operating position that causes the medium to be positioned in a desired position; and (d) an ink ejection controller for causing ink ejection portions of the recording head to eject the ink toward the medium. The feed controller includes: a target-operating-position changer for changing the target operating position as an original target operating position to a modified target operating position in which influence of a cyclic variation of an operation velocity of the feeder is smaller than in the original target operating position. The ink ejection controller includes: an ink-ejection portion shifter for shifting the ink ejection portions in upstream or downstream direction in which the desired position is shifted as a result of change of the target operating position.

摘要： An inkjet printer is configured to acquire gap variation information related to a variation of a gap between a specific portion of an ink discharging surface and a recording sheet as a function of an inkjet head position, the specific portion located within a usage nozzle disposed area where usage nozzle rows to be actually used are disposed, determine representative gap variation information related to a variation, as a function of the inkjet head position, of a representative gap representing actual gaps between the usage nozzle rows and the recording sheet, by multiplying the gap variation information by a correction coefficient dependent on a width of the usage nozzle disposed area in a head moving direction and a wavelength of a wave shape of the recording sheet, and determine ink discharging timing based on the representative gap variation information, assuming that the actual gaps are equal to the representative gap.

摘要： A conveyance device includes a linear encoder that outputs an encoder signal corresponding to displacement of a conveyed object. The encoder includes an encoder fence provided on an intersecting plane that intersects a reference plane orthogonal to a direction in which a guide element supports the conveyed object. The encoder fence is configured such that a plurality of light-transmitting portions and light-shielding portions are arranged alternately on a side of the encoder fence. The light-transmitting portions and the light-shielding portions are formed so that a first point on each boundary between each of the light-transmitting portions and each of the light-shielding portions adjacent to each other and a second point on the each boundary, which is positioned separately from the first point with respect to a direction along the side of the encoder fence and perpendicular to the conveying direction, are separately positioned with respect to the conveying direction.

摘要： A sheet-conveying device conveys a recording medium to a sheet support surface positioned downstream of the sheet-conveying device in a sheet-conveying direction when recording an image with an image-recording unit. A drive roller and a follower roller define a nip line therebetween. The nip line is positioned above the sheet support surface. A first support member rotatably supports the follower roller. A moving unit moves the first support member from a first position to a second position upstream of the first position in the paper-conveying direction immediately after a trailing edge of the recording medium leaves the sheet-conveying unit.
