An image forming apparatus includes a sheet feeder, a sheet conveyor, a line head, an image sensor, a moving mechanism, and a controller. The image sensor has a reading width in the main scanning direction smaller than main scanning direction widths of a largest printable size paper sheet. In setting for using a large width sheet, a controller controls a moving mechanism to move the image sensor toward one side so that a one side edge of the large width sheet can be read. Based on read image data obtained by reading, the controller recognizes a deviation direction and a deviation amount of a position of the conveyed large width sheet in the main scanning direction.

Systems and methods of adaptive nail printing and collaborative beauty platform hosting are disclosed. In one aspect, embodiments of the present disclosure include a method, which may be implemented on a system, to decorate a physical target. The method can further include determining a size of the physical target and adapting dimensions of the design to the size of the physical target. In a further embodiment, the design having the dimensions that have been adapted on to the physical target is printed. Moreover, content can be depicted while printing the design onto the physical target to decorate the physical target.

Devices and methods for identifying border positions of print media in image forming apparatuses are disclosed. In an example method print media are advanced in a feeding direction to reach a cutting position, a cutter is advanced in a cutting direction, perpendicular to the feeding direction to cut the print media, changes in friction are identified when the cutter contacts the print media, positions of the cutter are identified when the changes in friction are identified and border positions are determined based on the identifying of cutter positions.

Provided are an image forming apparatus for outputting a plurality of images having different sizes according to a method pre-set by a user without interrupting a current printing operation when the plurality of images having different sizes are obtained and a method of operating the image forming apparatus.

An edge detection unit is arranged in a conveying portion conveying a sheet and detects the edge of the sheet in the width direction perpendicular to the sheet conveying direction. A light source unit is arranged opposite the sheet. A detecting portion holder holds the edge detection unit and the light source unit. A conveying roller pair positions the sheet conveyed toward the edge detection unit. A unit housing houses the detecting portion holder and the conveying roller pair. The edge detection unit has a contact glass making contact with the sheet. The light source unit has a facing glass facing the contact glass. One glass out of the contact glass and the facing glass is inclined downward at a first angle with respect to the tangent line, which passes through the nip portion between the conveying roller pair, toward the downstream side in the sheet conveying direction.

In a case where a predetermined sheet size is selected by a user from a plurality of sheet sizes displayed on a display, an image larger than the predetermined size is printed. In a case where a sheet size is input by the user in an input screen displayed on the display, an image having a size corresponding to the input sheet size is printed.

A printing apparatus includes a liquid ejecting unit configured to eject liquid to a medium, a medium supporting unit configured to support the medium on a support face, a medium width detector configured to detect a width of the medium supported at the supporting face. Further, the printing apparatus includes a plurality of air blowing ports provided along a width direction (X-axis direction) of the medium for blowing air toward the medium supporting unit, an air blowing unit from which the air is blown, a heating unit configured to heat the medium supporting unit. Further, the printing apparatus includes a controlling unit configured to control a blowing amount from each of the plurality of air blowing ports according to the width of the medium detected by the medium width detector.

In a reading device, a controller performs: detecting occurrence of a double-feed; executing a double-feed process; detecting a state of double-fed sheets; executing a first process when a command is inputted; and executing a second process when the command is not inputted. The double feed process includes: halting conveyance of an original document; and making notification of the occurrence of the double-feed. The first process performs, in accordance with the command, one of: resuming the conveyance of the original document; and quitting the conveyance of the original document. The second process performs, in accordance with a determination result, one of: resuming the conveyance of the original document; and continuing the halting and the making. The resuming is performed when the determination result indicates that the conveyance of the original document is possible. The continuing is performed when the determination result indicates that the conveyance of the original document is impossible.

A printing apparatus includes a liquid ejecting unit capable of ejecting ink, which is a liquid, onto a medium and capable of reciprocating in a width direction (X-axis direction) of the medium, a medium support unit that supports the medium on a support face, a medium width detection unit that detects a width of the medium supported on the support face, a plurality of heating units that are provided along the width direction of the medium and heat the medium support unit, and a control unit capable of individually controlling the plurality of heating units. The control unit controls an output of each of the heating units in accordance with the width of the medium detected by the medium width detection unit.
