Abstract:
An apparatus for horizontally loading and unloading an ink-jet print cartridge from a carriage in a printer. The apparatus includes a generally rectangular print cartridge, an elongate supporting lip located on a side wall of the print cartridge, a carriage body, a chute mounted on the carriage for receiving the print cartridge, and a generally horizontal rail on a side wall of the chute for guiding the print cartridge into the carriage. In operation, the apparatus horizontally loads a print cartridge into a carriage by translating the print cartridge horizontally forward into a carriage, engaging a lip on the print cartridge with a guide rail on the carriage, sliding the print cartridge up and over a datum on the carriage with the guide rail and latching the print cartridge in the carriage. The apparatus unloads a print cartridge from a carriage by rotating the print cartridge about a datum on the carriage, unlatching the print cartridge from the carriage, and horizontally translating the print cartridge out of the carriage.
Abstract:
An ink jet recording system for recording using a recording head which discharges heated ink onto a recording medium through discharge ports includes temperature detection of ink discharged through the discharge ports, position of the recording head so that a temperature of ink discharged through the discharge ports can be detected, detection of discharge or non-discharge of ink based on the temperature detection, variation of discharge of ink droplets, and control of the variation during discharge detection.

Printing onto lenticular material using an elongate feed cylinder having a feeding surface with a plurality of transversely arranged grooves that are substantially perpendicular to a central longitudinal axis of rotation of the elongate feed cylinder.
Abstract:
An apparatus for setting radiation curable ink deposited onto a substrate. The apparatus includes a series of ink jet print heads which deposit ink onto the substrate, and a radiation source mounted laterally adjacent to the series of ink jet print heads. The amount of energy provided by the radiation source is sufficient to cause the radiation curable ink to set.
Abstract:
An inkjet printing method corrects for droplet placement errors. The method comprises fluid droplets self-registering on a patterned transferring surface that ensures that they are transferred to the correct pixel positions on the final printing surface. The invention also allows for the characteristics of the droplets to be changed while on the patterned surface. The properties may include, but need not be limited to, the size of the droplets, their viscosity and their more general rheological properties. For some applications, there is merit in the droplets changing their water solubility.
Abstract:
An ink jet printing method, comprising the steps of: A) providing an ink jet printer that is responsive to digital data signals; B) loading the printer with an ink jet recording element comprising a resin-coated paper support having thereon an ink-retaining layer comprising voided cellulosic fibers and organic or inorganic particles in a polymeric binder, the length of the voided cellulosic fibers being from about 10 &mgr;m to about 50 &mgr;m, the ratio of the voided cellulosic fibers to the organic or inorganic particles being from about 90:10 to about 60:40 and the ratio of the combination of voided cellulosic fibers and the organic or inorganic particles to the polymeric binder being from about 90:10 to about 50:50; C) loading the printer with an ink jet ink composition; and D) printing on the ink jet recording element using the ink jet ink in response to the digital data signals.
Abstract:
An embodiment of a drying apparatus for drying ink deposited onto media includes an electromagnetic energy source to generate electromagnetic energy. The embodiment of the drying apparatus also includes a rectangular waveguide coupled to the electromagnetic energy source. The rectangular waveguide includes slots in the axial direction of the rectangular waveguide on opposite sidewalls corresponding to the largest sides forming a cross section of the rectangular waveguide. The electromagnetic energy source is configured to establish a TE01 mode within the rectangular waveguide, resulting in an electric field substantially perpendicular to the longitudinal axes of fibers within the media and thereby reducing power dissipated within the media while providing sufficient power for drying the ink during a drying operation.
Abstract:
A printing machine for printing an image including colorants, including a liquid carrier, on a recording medium moving along a path through a pre-print zone and a print zone including a heat and hold drier. The printing machine includes a printhead, disposed adjacent the print zone, to deposit the colorants, including the liquid carrier, on the recording medium during movement through the print zone, a pre-print zone drier, disposed adjacent the pre-print zone, to generate a heat energy, towards the recording medium, sufficiently elevated for retention in the recording medium during movement thereof through the print zone. The pre-print zone drier includes the function of heat and hold where the pre-heat drier heats the recording medium sufficiently such that the mass of the recording media holds or stores the heat energy during printing in the print zone such that a drier is either not necessary at the print zone or the a drier generating less heat energy than the pre-heat drier is used to maintain the level of stored heat energy.
Abstract:
Printer performs accurate ink-discharge status detection, dependent upon the type of a printhead attached to the printer, the print mode and the color of ink change, and a facsimile apparatus using the printer. Each time printing based on received facsimile image data for one page of print sheet has been completed, the printhead is moved to a position close to a photosensor, and test ink discharge is performed. At this time, the type of printhead is determined, and whether or not the color printhead is in normally-dischargeable status is judged by comparing a pulsewidth obtained from output from the photosensor with a threshold value selected in accordance with the discrimination result. Otherwise, one of a plurality of threshold values according to print modes and ink colors is read from a ROM, and test ink discharge is performed with respect to corresponding color ink. The result of the discharge is compared with the threshold value. Thus, whether or not the printhead is in normally-dischargeable status is judged with respect to each color ink.
Abstract:
A method of computer-to-cylinder type lithographic printing comprising: loading a plate material on a plate cylinder of a printing apparatus; forming an image, based on image data signal, directly onto the plate material by an inkjet image-recording process comprising ejecting an oil-based ink from a recording head; heat-fixing the thus formed inkjet image to prepare a printing plate; and performing lithographic printing with the thus prepared printing plate, wherein said heat fixing step comprises heating with a heat roller. In a preferred embodiment, said heat-fixing step further comprises preliminary heating prior to said heating with the heat roller. Also disclosed are computer-to-cylinder type lithographic printing apparatuses for carrying out the printing methods.
