Plural unit heads are disposed in a paper conveyance direction, and recording head units are configured and disposed in a staggered manner. Head recovery devices are disposed as positions avoiding the locus of splattering of ink droplets from the unit heads. The recording head units can record an image across the entire width of a sheet of paper, and it is not necessary to move the recording head units in the paper width direction. Dummy jetting can be conducted at gap regions between two sheets of paper in an image recording section. The plural unit heads are unitized.

A pagewidth inkjet printer includes a support assembly. A housing is mounted on the support assembly and has a print medium inlet end and a print medium outlet end. A feed roller assembly is mounted on the support assembly proximate the inlet end to feed a print medium into the housing. A print engine is mounted on the support assembly, downstream of the feed roller assembly to carry out a printing operation on the print medium. An exit roller assembly is mounted on the support assembly proximate the outlet end of the housing. A gas inlet is arranged on the housing to permit drying gas to be introduced into the housing to facilitate drying of the print medium. The exit roller assembly is spaced from the print engine such that sufficient time is provided for the ink to dry as the print medium is displaced from the print engine to the exit roller assembly.

A double sided print engine assembly includes opposed rollers to transport paper to be printed. Mounted adjacent the opposed rollers are corresponding opposed ink supply moldings. The ink supply moldings include arcuate portions that terminate proximal the nip of the opposed rollers and which support opposing printheads. By locating the printheads close to the nip they print upon a taut portion of the paper thereby resulting in more accurate deposition of ink drops on the paper.

A high volume printing assembly includes an array of printers. Each printer includes a housing. Locking fee project beyond the housing on one side. Apertures corresponding to the fee are located on an opposing side of the housing to receive the feet of a neighboring printer. The printers are daisy-chained together by means of serial data-in and data-out ports. A control station is provided to monitor and control the array. The array may be disposed as a column of printers mounted upon a suitable table or alternatively it can also be provided as a row of printers stacked side by side upon a suitable mounting frame. In a preferred embodiment each of the printers is of a high-speed type that includes a pagewidth printhead.

An image formation apparatus and method forms an image on a recording medium and includes a toner applying step for applying fusible powder toner to a recording medium to form a toner image, a semi-fixing step for semi-fixing the toner image, an ink applying step for applying liquid ink containing a coloring to the recording medium to form an ink image, and a thermal fixing step for thermally fixing an image formed by the toner applying step and the ink applying step.

Print is made on a recording paper by running an ink carriage along the supporting axis in a reciprocating motion. The ink carriage includes ink heads respectively provided with a front ink nozzle and a back ink nozzle facing their respective directions, so that print is made simultaneously at two portions on the recording paper along the transportation direction in which the recording paper is transported through a single transportation path one by one. Consequently, there can be provided an ink jet printer which can improve printing efficiency by increasing a printing rate and printing resolution, and realizing printing of an overstrike character, simultaneous printing of mixed information, double-side printing, etc.

A printing device that produces printed pieces of paper having no blank is provided, which can precisely position the print to contents on the back side of the printing paper. A mark (36) is provided in a blank area (38) on the back side of printing paper (3a). A sensor (7) senses the mark (36), whereby the position of a regular-form print area (37) adjacent to the blank area (38) on the printing paper (3a) can be recognized. A thermal head (1a) and a cutter (6) print the printing paper (3a) and cuts the blank area (38) away on the basis of the sense output. Accordingly, it is possible to produce a printed piece of paper having a desired print on the front side and a regular-form print on the back side printed without positional misalignment and without blank in the feed direction, with the mark (36) removed therefrom.

The present invention relates to a printer with a single printing motor and a single non-contact heating element characterized in that it includes a printing width and a paper path width greater than that of a double web width between 18.5" (46.99 cm) and 20.5" (52.07 cm), and selective control of the writing heads. The writing heads are controlled either in order to use them in a single group to print a centered double-width web, or to use them in two groups of heads to concomitantly print two single-width webs separated by a margin. Both groups of heads or each group of heads can be supplied with one color of ink.

A single pass printer, having a printing width (PW) is provided for printing a toner image on a substrate, the substrate having a width (WS) and a length (LS), wherein, i) a number n, equal to or larger than 2, of printing engines, each containing a toner transferring element with a longitudinal axis (width (WPE)) smaller than the printing width (PW) are present, and at least two of the n printing engines, each containing a toner transferring element with a longitudinal axis in the direction of width (WPE), are located so that the longitudinal axis do not coincide. Preferably the printing engines are electro(stato)graphic engines, especially Direct Electrostatic Printing (DEP) engines or electrophotographic engines.
摘要:
A multi-head printer, and a driver therefor, in which the multi-head printer has at least a wide width print mode and a standard width print mode. At least first and second print heads are mounted for lateral reciprocal movement across a support surface for a recording medium, with the first and second print heads being laterally displaced with respect to each other such that both the first and second print heads can print a first lateral print area and such that only the second print head can print a portion of a second and larger lateral print area. In the standard width printing mode, fully or partially overlapped printing in the first lateral print area can be effected by both of the first and second print heads. In the wide width print mode, printing by only the second print head is effected, and not by the first print head. An additional wide print mode may be provided for partially overlapped printing by the first and second print heads, with the second print head printing primarily in the second lateral print area. Based on print head configuration, such as the type and color capability of print heads mounted in the first and second print heads, available print modes are determined, from which one of the available print modes is selected for effecting printout by the printer.
