摘要： A controller controls a floating unit and a conveyor to convey a sheet to a supply destination, and performs a following control of acquiring a detection value of a detector which detects an output signal acquired due to an input to a side of a sheet stack, during floating of sheets floated by the floating unit each time a sheet is conveyed by the conveyor and lifting a stacking tray upon the acquired detection value being less than a threshold value. The controller controls the floating unit and the conveyor to perform a feeding retry upon an occurrence of empty feeding in the conveyor, and determines the threshold value such that a target position for a height position of an upper surface of the sheet stack in the following control is a position where empty feeding is more likely to occur than multiple sheet feeding in the conveyor.

摘要： A paper supply device is equipped with a paper supply unit that sequentially supplies a plurality of print media, and a control unit that controls the paper supply unit. During sequential supply of a plurality of print media at a paper supply interval, in the case that it is necessary to secure a paper supply interval which is set in advance and is longer than the paper supply interval, a reference paper supply interval, based on a point in time which is a natural number multiple of the paper supply interval, and a post print process paper supply interval are compared. Print media are supplied at the post print process paper supply interval in the case that the post print process paper supply interval and the reference paper supply interval are different.

摘要： An inkjet printing apparatus includes: a first and a third head that ejects ink onto a print medium to form a printed image; a second head that coats the print medium with a treatment agent that contains a coagulant that coagulates ink; and a control unit that performs a two step ink ejection control process to control the first through third heads such that ink is ejected onto the print medium until a printing rate in a predetermined region of the print medium reaches a threshold value which is set in advance, coats the treatment agent thereafter, and then ejects ink according to a remaining printing rate after the treatment agent is coated.

摘要： A droplet ejection control apparatus includes a head unit in which a plurality of vertically arranged nozzle groups in which a plurality of nozzles for ejecting droplets onto a predetermined target of ejection are arranged in the vertical direction; and a control unit for controlling ejection of the droplets from the nozzles. The control unit controls ejection of the droplets for vertically adjacent nozzle groups such that an amount of ejection from at least one nozzle of a vertically upper nozzle group at a joint portion between nozzle groups is reduced, and an amount of ejection from at least one nozzle at the joint portion between the nozzle groups of a vertically lower nozzle group is increased.

摘要： A method for producing a transfer sheet is provided that yields excellent fastness properties in the transferred product for the image transferred from the transfer sheet. The method for producing a transfer sheet includes: forming an image by jetting an aqueous ink by an inkjet method onto a releasable support, and jetting an aqueous adhesive liquid by an inkjet method so as to at least partially overlap the image, wherein the aqueous adhesive liquid contains a resin A, and a resin B having a glass transition temperature that is at least 80° C. higher than that of the resin A.
