A transport apparatus includes a feed unit as an example of a supply unit which supplies a medium in a transport direction, and a transport unit which transports the medium supplied from the feed unit. The transport unit includes a transport roller (a driving roller) which sends the medium, and a driven roller which nips the medium between the transport roller and the driven roller. The driven roller is movable in the transport direction relative to the transport roller.

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.

A motor of a printer is capable of rotating at a rotation speed controlled to be constant based on a rotation position of a motor shaft measured by a motor encoder so as to move a carriage. A linear encoder measures positions of the carriage in a moving direction. Differences between each of rotation positions of the motor shaft based on the measurement by the motor encoder and a corresponding rotation position of the motor shaft based on the measurement by the linear encoder are calculated, for positions rotation during one or more rotation(s) of the motor shaft. A correction value to be added to the rotation positions of the motor shaft measured by the motor encoder is determined, based on the calculated differences, such that a change in the rotation speed of the motor shaft, during one rotation thereof, based on the measurement by the linear encoder, is decreased.
