摘要： A method for reducing the effects of printhead carrier disturbance during printing with an imaging apparatus having a printhead carrier for carrying at least one printhead includes the steps of accelerating the printhead carrier from a first position in a first direction; printing with the printhead in the first direction; and changing a rate of acceleration of the printhead carrier for a subsequent accelerating of the printhead carrier from the first position in the first direction prior to a subsequent printing with the printhead in the first direction to phase shift the printhead carrier disturbance.

摘要： A printer (1) in which a first sheet (5) to be imaged by printhead (3) is followed by a trailing media sheet. The first sheet is stopped intermittently so that the printhead can traverse the first sheet to print a partial image. The trailing media sheet is stopped behind the first sheet and is moved intermittently until it reaches or is near nip rollers (9a, 9b). Exit rollers 11a, 11b, 11c, and 11d move the first sheet out of the printer. When the exit rollers and the nip roller move forward and backward together the first sheet may be exited before the nip rollers are reversed to align the second sheet. Alternatively, the first sheet may be moved backward during alignment. The intermittent movement of the sheets may be at different times and with the trailing sheet moved less times and longer amounts than the first sheet is moved.

摘要： The invention provides an apparatus and method for printing an image using the printhead of an ink jet printer. The printhead ejects ink drops on a print medium in a series of scanning passes, and different addressing patterns are selected in each scanning pass to address ink drop locations for different portions of the raster lines addressed by each scanning pass. Addressing patterns having various interlacing percentages are selected in order to produce overlapping boundary regions between passes. The overlapping boundary regions minimize the banding effects that occur with inexact ink drop placement.

摘要： A method for reducing banding during printing with an imaging apparatus includes establishing a current original move length; determining a current original absolute position; calculating a current adjusted absolute position based on the current original absolute position; determining a current difference between the current original absolute position and the current adjusted absolute position; determining a current move-to-move adjustment amount by subtracting the current difference from a previous difference between a previous original absolute position and a previous adjusted absolute position; and generating an adjusted move length for a next move by adding the current move-to-move adjustment amount to the current original move length.
