A controller forms an image on a print medium by alternately repeating: a first operation of driving an inkjet head to eject ink from the inkjet head to the print medium while driving a main scanning driver to move the inkjet head in a main scanning direction; and a second operation of driving a sub-scanning driver to move a shuttle in the sub-scanning direction. The controller performs a multi-stage brake control to stop the shuttle in the second operation, and in a second stage and a stage after the second stage of the multi-stage brake control, apply brake to the shuttle at such a timing that a direction of vibration of the shuttle and a direction of force of inertia of the shuttle in braking of the shuttle are opposite to each other.

Provided is a printer having: a carriage configured to carry and move a printhead; a camera attached to the carriage and configured to photograph an image printed by the printhead; an adjustment mechanism configured to adjust an installation position of the camera; and a processor configured to control to move the carriage to a position of a predetermined specific mark, photograph the specific mark by the camera, and based on a photographed image of the specific mark, adjust an installation position of the camera by the adjustment mechanism.

A plate-like detection plate portion that undergoes strain due to contact with an object is used for detecting the presence of an object that can come into contact with a liquid ejecting unit with relative movement between a medium and the liquid ejecting unit, and is provided with a piezoelectric film sensor that outputs an electric signal corresponding to strain of the detection plate portion. The piezoelectric film sensor includes a detection film portion in which a piezoelectric element that causes a voltage change corresponding to the strain is arranged, and an output circuit portion that converts the voltage change of the detection film portion into an electric signal and outputs the electric signal. The output circuit portion is provided on a second plate surface, which is a rear surface of a first plate surface facing the medium, of the detection plate portion.

A method and apparatus for subdividing and printing regions of a substrate with multiple print heads or multiple print head assemblies which substantially decreases printing time is described. The method includes a feathering method which reduces overlap artifacts which is useful in any printing situation where adjacent regions are printed that could be misaligned, offset, or have slightly different colors.
