摘要： A portable large format inkjet printer for printing an image at a media print area of a stationary flat media includes an inkjet print engine having a printhead carrier system configured to dynamically scan an inkjet printhead over the media print area in each of two orthogonal directions during the printing of the image. An alignment frame is configured to fixedly mount the inkjet print engine to facilitate a manual positioning of the alignment frame and the inkjet print engine in unison. The alignment frame has an open interior window within which the inkjet printhead is moved and from which all printing occurs. At least one alignment panel is mounted to the alignment frame. Each respective alignment panel has an alignment indicia configured to facilitate accurate manual positioning of the portable large format inkjet printer at a desired printing position at the media print area.

摘要： An oscillation device includes an oscillator, an oscillation detection unit that detects oscillation of the oscillator and outputs an oscillation detection signal, and a drive unit that generates a drive signal in keeping with the oscillation detection signal and outputs the drive signal to the oscillator. The drive unit includes a phase shift unit that shifts the phase to provide the drive signal as positive feedback to the oscillator. The phase shift unit includes a disturbance generating unit that outputs the periodic signal, a fluctuation unit that causes the amount of phase shift to fluctuate based on the periodic signal, a drive amplitude detection unit that detects the amplitude of the drive signal and outputs a drive amplitude signal, a product detection unit that outputs a detection signal after performing product detection on the drive amplitude signal based on the periodic signal, and an adjustment unit that adjusts the phase-shift amount based on the detection signal.

摘要： An imaging apparatus includes a print engine having a printhead that generates ink drops, and a printhead carrier that carries the printhead in a first direction and in a second direction. A controller determines an initial print direction based on ink drop information obtained by printing patches in the first direction and in the second direction. The controller is operatively coupled to the print engine to print an image based on the initial print direction.

摘要： A method for controlling an inkjet printing system including calculating a pigment concentration of ink ejected by the inkjet printhead relative to an initial pigment concentration of the ink based on a determined height of ink in an ink reservoir and a determined period of time since a last printhead activation. A firing pattern for the inkjet printhead is determined based on the determined height, the determined period of time and the calculated relative pigment concentration to account for settling of ink stored in the ink reservoir.
