A banknote conveying apparatus includes, a conveyance controller that performs a conveying process of sequentially conveying a plurality of banknotes on a conveyance path, a plurality of sensors that detect the conveyed banknotes, and a processor coupled to a memory and configured to, generate a log in which past operation information including a detection result by the sensor is recorded, calculate an abnormality tendency threshold of a conveying speed for conveying a banknote between the sensors based on detection results of the sensors for the plurality of conveyed banknotes included in the log, and calculate a first conveying speed of a specific banknote between the sensors based on the log and determine presence or absence of an abnormality sign in conveyance of the specific banknote between the sensors based on whether the first conveying speed is included in a range indicated by the abnormality tendency threshold.

Provided are a printing apparatus and a printing method that can realize improvement of drying properties, suppression of substrate deformation, and suppression of jetting failure. The printing apparatus includes a print head that jets an aqueous ink onto a substrate to form an image, a substrate moisture reduction unit that reduces moisture of the substrate before the image is formed by the print head, and an absolute humidity adjustment unit that adjusts an absolute humidity in a periphery of a nozzle surface of the print head.

A medium processing apparatus includes a conveying unit, a liquid applier, and a crimper. The conveying unit conveys a medium in a conveyance direction. The liquid applier applies liquid to the medium conveyed by the conveying unit. The liquid applier includes a presser and a liquid application member. The presser presses the medium. The liquid application member contacts and is separated from the medium while the presser presses the medium. The crimper presses and deforms a plurality of media including the medium to which the liquid is applied by the liquid applier, to crimp and bind the plurality of media.

A sheet stacker includes a stacking member, transporting member, guiding member, a plurality of blowers, and controller. A sheet is stacked on the sheet stacker. The transporting member transports a sheet in a sheet-transporting direction towards the stacking member. The guiding member retains an edge portion of the sheet transported by the transporting member in a standby position, followed by moving in the sheet-transporting direction to guide transporting of the sheet. The blowers discharge air flows towards the sheet transported to the stacking member. The air flows are directed towards a top plane of the stacking member. One of the blowers is disposed in a position corresponding to the detaching position. The controller controls motions of the blowers and air volumes from the blowers based on information regarding a length of the transported sheet.

A control apparatus capable of reducing labor required for a user to set a sheet feeding unit is provided. The control apparatus that sets a sheet feeding unit to be used in a printing processing performed by an image forming apparatus including a plurality of sheet feeding units includes at least one processor, and a memory coupled to the processor storing instructions that, when executed by the processor, cause the processor to function as an obtaining unit that obtains information about sheets, which have been fed into the plurality of sheet feeding units, and a display control unit that displays a setting screen for allowing a user to select the sheet feeding unit to be used in the printing processing. Information about a virtual sheet feeding unit obtained by integrating two or more sheet feeding units, into which sheets satisfying a predetermined condition have been fed, into one is displayed.

An image forming system includes: an image forming apparatus that forms an image on a recording medium; a post-processing device that executes post-processing to the recording medium on which the image is formed by the image forming apparatus; a physical property detector that detects physical property information of the recording medium; and a hardware processor that determines a restriction content of the post-processing based on registered post-processing restriction information depending on the physical property information having been detected.

A hair foil dispenser (100) has a main casing (101); a removable covering (200); a roller arrangement including a driving roller (142) and a tensioning roller (140) for pulling foil (300) from a foil roll (320); a motor (830) provided to drive the driving roller (142); a cutting mechanism (160) for cutting at least one sheet of the foil (300) with a predetermined length; a proximity sensor (100, 810); and a control unit (500) provided to receive at least one signal from the proximity sensor and, upon sensing the presence of a user, to actuate the motor (830) to cause the roller arrangement to pull foil from the foil roll (320); and to actuate the cutting mechanism to cut the foil. The user can repetitively direct the dispenser to dispense a predetermined number of the foil sheets without requiring physical contact of the dispenser by the user.

A medium processing apparatus includes a conveying unit, a liquid applier, and a crimper. The conveying unit conveys a medium in a conveyance direction. The liquid applier applies liquid to the medium conveyed by the conveying unit. The liquid applier includes a presser and a liquid application member. The presser presses the medium. The liquid application member contacts and is separated from the medium while the presser presses the medium. The crimper presses and deforms a plurality of media including the medium to which the liquid is applied by the liquid applier, to crimp and bind the plurality of media.
