A printer including at least two tractor unit mounting sections upstream of the print position in the sheet feed direction, and at least one tractor unit can be mounted on either of these tractor unit mounting sections. The sheet feeding direction can thus be selected freely in accordance with the web replacement frequency or the printer installation location merely by changing the mounting position of the tractor unit. If the number of tractor units is increased, a plurality of webs can be set up simultaneously and used selectively.

An ink jet printer including a carriage which moves along a print area, a head mounted on the carriage, an ink cartridge mounted on the carriage for supplying ink to the head, a lever on the carriage for mounting or demounting the ink cartridge with respect to the carriage and a stopper for stopping the movement of the carriage by coming into contact with the lever when an operation of mounting the ink cartridge by the lever has not been completely effected. The ink jet printer may also include a resilient member for supporting the ink cartridge on the carriage.

Disclosed is a paper feeder for sequentially feeding laminated cutform paper to a record/write portion or the like. Proper sagging of the cutform paper is produced on this side of a paper feeding roller during rotations of the paper feeding roller in an anti-feeding direction, thus adjusting the direction thereof. Subsequently, with rotations of the paper feeding roller in a paper feeding direction, a feed roller is temporarily rotated. The paper feeding roller is caused to exactly pull in the cutform paper without exerting abrupt fluctuations in load on the paper feeding roller and the cutform paper.

An ink jet printer is provided for ejecting ink droplet to paper fed into a recording section. The ink jet printer includes a print head. An ink intercept plate is disposed is disposal on a paper feed path. The intercept plate includes a print surface which has a slope which declines along the advancing paper feed direction. The print surface is disposed opposite the print head. A groove extends away from the print surface of the ink intercept plate for transporting unused ink away from the print surface.

In a printer, a bottom of an automatic paper feeder is formed by a bottom itself of a printer case; an operation lever is provided for operating a hopper and separation pawls arranged in a stacker section; a spring member is used as a changeover mechanism for a paper feed-in roller; an ink shielding portion is provided over an entire print area; the paper is discharged while forcibly urging the paper in a concave shape in which its printed surface is concaved; and a changeover is effected between a paper feeding operation and a pumping operation by a carriage at both ends of a carriage-moving area.
摘要:
An actuation mechanism for a lever including a spring member supported by the lever and frame of the printer and an actuation portion for rotating the lever by pressing and displacing an intermediate portion of the spring member. The printer may include a feed-in roller for feeding sheets of paper, a carriage for printing the sheet fed by the feed-in roller, a feed-in gear for rotating the feed-in roller, a movable gear rotatably supported by a rotatable lever and capable of assuming a first position in which the movable gear meshes with the feed-in gear to rotate the feed-in gear and a second position in which the movable gear does not mesh with the feed-in gear, and an actuation mechanism.

In printing using a plurality of chromatic color inks of different lightness interchangeable with one another in color reproduction, ink consumption is reduced while preserving the quality of the printed result. On the basis of first color data represented in terms of density of a first reference color, second color data represented in terms of density of a plurality of second reference colors is generated. The plurality of second reference colors are the ink colors. They include two same hue reference colors of different lightness interchangeable with one another when reproducing a certain color. The lookup table holds the first color data and the second color data associated with one another. For a set of densities of a plurality of second reference colors representing achromatic color of higher lightness than the reference lightness, density of the same hue reference color having lower lightness is 0. The reference lightness is lightness equal to or less than the minimum lightness which is the lightness of the color having the lowest lightness among the colors that can be reproduced on a printing medium using only ink of the darker color of the two same hue reference colors.

A client controls printing of color chips (images for colorimetry) with a plurality of tones for individual color inks (printing colorants). The client acquires from a server a tone value correction table (color matching information) to match standard colors. The server can acquire the lightness data of color chips for individual inks and create the tone value correction table based on the lightness data of color chips of individual color inks and the lightness data of standard colors corresponding to the color inks, and subsequently send the color matching information to the client. As a result, it is easier to produce colors that match standard colors.
