Printers capable of determining a media type of a media and associated methods are provided. An example method includes scanning a media with a verifier associated with the printer to generate at least two consecutive windows of the media. The example method further includes determining a vertical length of a captured image based on a comparison of image characteristic values captured in the at least two consecutive windows. The example method further includes determining a media characteristic associated with the media based at least on the captured image and the vertical length and one or more stored media profiles. The example method further includes calibrating the printer based on the media characteristic.

A nail polish application apparatus, comprising a mounting element comprising a capsule compartment adapted to receive one or more capsules containing a nail polish fluid wherein the mounting element is moveable by actuator(s) in longitudinal axis crossing a nail polish applying space and in lateral axis perpendicular to the longitudinal axis and is rotatable by the actuator(s) around the longitudinal axis, a pressure applying element adapted to apply pressure on a body portion of the capsule(s) installed in the capsule compartment wherein the body portion defines a reservoir containing a nail polish fluid, the pressure builds an internal pressure in the reservoir forcing extrusion of the nail polish fluid to a nail polish applying element integrated with the capsule(s), sensor(s) adapted to generate sensory data depicting the nail polish applying space and a control unit adapted to operate the actuator(s) and the pressure according to analysis of the sensory data.

A control unit of an image reading apparatus acquires, at an upstream position in a medium transportation direction of an abnormality determination area set for a leading-edge area of a medium, a distance WL from a center position in a medium width direction intersecting with the medium transportation direction to one edge in the medium width direction and a distance WR from the center position to the other edge in the medium width direction, and compares a value R that is a ratio between the distance WL and the distance WR or a difference therebetween with a threshold R0 determined in advance.

An image reading apparatus according to the present disclosure includes: a platen glass on which a document is placed; a light source, an image sensor; an image reading unit for optically reading an image of a reading area of the image sensor; a rotatable document cover for covering the platen glass; a cover state detection unit for the document cover; a control unit to detect a sensor output level of the image sensor; and a document size specification unit for the document. The control unit causes the image reading unit to perform a reading operation for specifying the size of the document in the main scanning direction in a state in which the document cover is open, and causes the light source to emit a predetermined light amount in the reading operation, which is larger than the light amount when the document image is read from the document.

An image reading apparatus includes a medium mounting portion configured to mount a medium; a feeding means configured to feed a medium from the medium mounting portion; at least one edge guide each configured to regulate a corresponding one of at least one medium width direction edge of the medium having been mounted on the medium mounting portion; a reading means configured to read the medium and disposed on a further downstream side than the at least one edge guide in the medium feeding direction; and at least one medium detection means configured to detect the medium and disposed on a further downstream side than the at least one edge guide in the medium feeding direction and further outside in the medium width direction than at least one edge regulation position for the edge regulation by the at least one edge guide.

A kit for usage by a nail polish application apparatus, the kit comprising one or more nail polish capsules. Each of the nail polish capsule(s) comprises a body portion defining a reservoir containing a nail polish fluid and a non-screw detachable cover having an integrated nail polish applying element. The non-screw detachable cover is mechanically coupled to an upper face of the body portion to seal an opening in the upper face.

An image formation apparatus includes an image former and a detection sensor. The image former forms an image on paper delivered in a first paper delivery path. The detection sensor includes an irradiator and an acquirer. The irradiator and the acquirer are arranged at positions facing each other through the first paper delivery path. The irradiator irradiates the paper with a predetermined pattern image while the paper is passing through the detection sensor. The acquirer acquires a calculation image including a transmission image formed after the predetermined pattern image has been transmitted through the paper. In the image formation apparatus, the degree of image expansion is calculated from a predetermined area including the transmission image in the calculation image, and printing conditions are adjusted according to the degree of image expansion.

Sheet feeding has been started after storing image data for one page of a document. A control method for a printing apparatus includes feeding a sheet from a sheet holding unit by a feeding unit, reading an image of a document by a reading unit, storing image data of the document read by the reading unit in a storing unit, and reading out, before image data for one page of the document is stored in the storing unit, the image data of the document from the storing unit and printing, by a printing unit, the image based on the read image data to the sheet fed from the sheet holding unit by the feeding unit, in which the feeding unit is able to start to feed the sheet from the sheet holding unit before the image data for the one page of the document is stored in the storing unit.

Provided are systems and methods for identifying, isolating, and/or aligning sheets. An identification system can facilitate accurate identification of a sheet by (i) vacating one or more components of the system that are not the sheet from a zone of detection, and/or (ii) determining a reference axis of the sheet. An isolation system can facilitate accurate isolation of a sheet by (i) providing targeted air flow, and/or (ii) introducing a wave into the sheet. Identification systems and/or isolation systems described herein may facilitate isolation of sheets that were previously fastened together by one or more fasteners. An alignment system can facilitate accurate alignment of a first sheet at an upstream location relative to a second sheet at a downstream location via machine learning.
