Patent number: 5537925Abstract: An infra-red dryer utilizes high velocity air jets which scrub and break up the moist air layer which clings to the surface of a freshly printed and/or coated sheet. The high velocity air jets are directed through multiple air flow apertures across an array of infra-red lamps onto the freshly printed and/or coated sheets.

To remove a fabric web from a surface, like a stack of such webs, a device places needles partially into the web. Since the needles extend into the fabric less than about nine tenths of the fabric's thickness, they can only attach to the upper surface of a single web. The needles, after insertion into the web, separate from each other to effectuate a firm connection. When the device raises, it can only lift a single web. When a fabric web receives printing, touching it with a heated block having a Teflon surface cures the ink. This permits its subsequent printing or collecting and stacking. A fabric web may adhere to a supporting surface through suction.Type: GrantFiled: March 16, 1994Date of Patent: April 9, 1996Assignee: QST Industries, Inc.Inventor: Warren N. Crawford

Patent number: 5488907Abstract: An image is printed on a medium by means of an ink jet printer using an ink composition comprising heat activated ink solids, without activating the ink solids during the process of printing onto the medium. The image is transferred from the medium to the object on which the image is to permanently appear by applying sufficient heat and pressure to the medium to activate and transfer the ink to the object.Type: GrantFiled: September 1, 1994Date of Patent: February 6, 1996Assignee: Sawgrass Systems, Inc.Inventors: Ming Xu, Nathan Hale

Patent number: 5489926Abstract: A high density graphics image can be printed without smearing by contact with a second page, without any unnecessary reduction of throughput. Throughput enhancement logic is inhibited during the printing of the second page for a variable delay related to the image density of the first page. The variable delay is calculated as a linear function of both the density (relative to a predetermined grid size) and the location if the densest portion of the first page, using coefficients which are different for different print modes. In one preferred embodiment, a maximum density is calculated by counting drops of ink in each of several overlapping grids, and the magnitude and location of the maximum density grid on a prior page is used to limit the throughput of a next page until a sufficient delay has elapsed to ensure that ink on the prior page will not be smeared when it comes into contact with the next page.Type: GrantFiled: April 30, 1993Date of Patent: February 6, 1996Assignee: Hewlett-Packard CompanyInventor: Jason R.

Patent number: 5399039Abstract: An ink-jet printer having improved print quality and full color printing capability on plain paper media. To accommodate placement of both input and output media trays on the same side of the printer housing for operator convenience, a paper path with a direction reversal is employed. A low cost radiant print heater with a reflector cavity heats the medium at the print area to increase the ink carrier evaporation rate. The printer provides improved medium control at the print area through an arrangement of small diameter drive and tension shafts and shortened handoff distance between the rollers. The heater is disposed between the drive and tension rollers. To minimize the handoff distance, portions of the drive rollers extend into the reflector cavity. The resulting media advancement mechanism has low inertia, with improved media positioning accuracy.Type: GrantFiled: April 30, 1993Date of Patent: March 21, 1995Assignee: Hewlett-Packard CompanyInventors: Robert R. Giles, Abdolreza Movaghar, Damon W. Broder, Stephen B. Witte, Brent W. Richtsmeier, Todd R. Medin

Patent number: 5349905Abstract: A thermal ink jet printer incorporates a copy speed feed control for reducing peak power requirements. Printing data supplied to the printer is scanned to determine image density or power consumption to dry ink in a dryer is determined. The speed of the sheet transport system is controlled in accordance with the image density so that, at high image densities, the speed of the sheet at the printer and/or at the dryer is reduced. A controller controls the speed of a drive motor driving the transport system in accordance with a determination of the density of the printed image from image print data or energy required for ink drying. A printer employing on-demand workstations having potentially high peak power usages can be made compatible with conventionally provided power supply systems.Type: GrantFiled: April 5, 1993Date of Patent: September 27, 1994Assignee: Xerox CorporationInventors: Thomas N.
