Abstract: A printing apparatus including a discharge head that performs scanning movement with respect to a print medium and discharges ink to a surface of the print medium, a signal output unit which includes a reference scale in which optical density changes stepwise along a scanning movement direction of the discharge head and a reading unit that optically reads the reference scale and outputs a signal according to the optical density and in which the reference scale and the reading unit move relatively with each other along with the movement of the discharge head, and a stain detection unit that detects stain of the signal output unit based on a detection result of a strength level of the signal.

Abstract: A recording apparatus includes a transporting unit which transports a recording medium and a recording unit which records data (e.g., prints) on the recording medium. A control unit controls the recording unit and the transporting unit. A detection unit detects a back end of the recording medium at a more upstream side of a transporting path than the recording position of the recording unit. A first judgment unit determines whether a scheduled recording is possible when the recording medium, while being transported, reaches a position where the recording should be performed when the detection unit detects the back end of the recording medium. A second judgment unit determines whether a portion of the scheduled recording to the recording medium is possible when the recording medium is transported to the position where the recording should be performed.

Abstract: Provided is a serial recording apparatus including: a feed unit which feeds a recording medium; a recording unit which performs recording with respect to the fed recording medium; a movement unit which moves the recording unit in order to performing recording; a transporting unit which transports the recording medium in a direction crossing the movement direction of the recording unit; a controller which controls the recording unit, the movement unit, the transporting unit and the feed unit; and a determination unit which determines whether a target stop position of the recording unit satisfies a target position condition, during the movement of the recording unit, wherein the controller starts a feed operation of the subsequent medium using the feed unit at a timing before the movement of the recording unit is stopped, if the target stop position satisfies the target position condition.

Abstract: There is provided a liquid ejecting apparatus for ejecting liquid to a printing material, having a platen for supporting the printing material, an ejection head for ejecting the liquid to the printing material by reciprocating on the printing material supported by the platen, an optical sensor reciprocating together with the ejection head and having a light emitting section for emitting light toward the printing material and the platen and a light receiving section for receiving light reflected from the printing material to optically detect whether or not the printing material exists, a usage measuring section for measuring usage of the liquid ejecting apparatus and a correcting section for correcting a result detected by the optical sensor based on the usage measured by the usage measuring section.
