A droplet deposition analysis system for an ink jet printer including a flexible transparent substrate. The printer may include a light source on one side of the substrate, and an optical detector on the other side of the substrate.
Abstract:
A system for controlling and displaying the printing format of dot matrix printers includes a microprocessor, a memory which is loaded with programs from replaceable software cards, and a control panel having a plurality of control buttons, an aligned display, and a rotary control coupled to the microprocessor. In a first mode, depression of a selected control button accesses the corresponding one of the parameters of the most commonly used print parameters and repeated actuation of the selected control button cycles through the options contained within the parameter, the parameter and current option being sequentially presented on the display. In a second mode under microprocessor control, each one of the parameters in a printing parameter menu is sequentially accessed and rotation of the rotary dial provides scrolling through each option contained within the parameter. Sets of selected parameter options can be saved under specified designations for later retrieval and use. The rotary control is also independently used to move paper and printhead to starting positions. Thus a great number of parameters, with a number of options for each parameter can be selectively set by an operator in an exceptionally easy to understand and use manner.
Abstract:
A method for printing an image with a printing system including the steps of multitoning image data to produce a multitoned image having a multitone resolution; providing a look-up table, wherein each look-up table entry specifies a number of dots of a first size and a number of dots of a second size; using the look-up table to expand the multitoned image data from the multitone resolution to a print-ready image having a printing resolution; and printing the print-ready image using a first array of dot forming elements for forming dots of a first size and a second array of dot forming elements for forming dots having a second size that is greater than the first size.
Abstract:
A fold out bench type boat seat assembly is attached to the bulkhead of a boat. The seat assembly comprises two sections: a backrest that is fixedly attached to the bulkhead, and a seat unit that is movable from a vertical stored position against the boat bulkhead to a horizontal seating position the major portions of which are detachable from the bulkhead when not needed.
Abstract:
A method of calibrating a media advance in a printer includes providing a mask to specify a printing configuration of a calibration target; forming a media feed calibration target on the print media by: i. printing the calibration target on a print media using an array of the marking elements, ii. advancing the print media by a media advance amount, iii. printing the calibration target on the print media using the array of the marking elements; iv. advancing the print media by the previous media advance amount plus an offset amount, and v. repeating steps iii. and iv. until the media feed calibration target is complete; measuring the optical reflectance of the media feed calibration target as a function of position along the media feed calibration target; identifying a position along the media feed calibration target corresponding to the location at which a maximum in the optical reflectance occurs; and comparing the location at which a maximum in the optical reflectance occurs to a predetermined location of the media feed calibration target to calibrate media advance in the printer.
Abstract:
A seating assembly is made up of both fixed and positionable components. The assembly in a first position provides in a back-to-back relation respective oppositely facing seats. In a second position the assembly provides a substantially horizontal lounge a portion of which is withdrawn from a stored position below the seats. The lounge when withdrawn includes the sitting surface portion of a selected one of the oppositely facing seats as part of the lounge and when stored utilizes such sitting surface portion as part of the selected seat.
Abstract:
An ink delivery system delivers ink from a stationary ink supply to a print cartridge on a movable carriage. The system comprises an ink container, a reservoir, and a flexible tubing connecting the reservoir to the print cartridge. The ink container has an internal cavity not open to atmosphere holding a supply of ink, and an air inlet channel and an ink exit channel. The ink reservoir has fluid channels to mate with the air inlet channel and ink exit channel on the ink container, and an air opening on the upper portion to connect the internal space of the reservoir to atmosphere and an ink exit port. The ink level in the ink reservoir is controlled by allowing the ink to rise to a level where the ink blocks the air channel into the ink container thereby preventing air to flow there through.
Abstract:
A color inkjet printer and method of printing includes a printer carriage supported for bi-directional movement along a print swath axis. Color inkjet printheads of different colors are mounted for movement with the carriage. The printheads are mounted in only two rows which are directed along the print swath axis. One row of the two rows of printheads is formed of printheads for printing a first primary color and a printhead for printing black. Another row of the two rows of printheads is formed of printheads for printing a second primary color and a printhead for printing yellow. Nozzle arrays of printheads for printing the first primary color and the nozzle array of the printhead for printing black do not overlap in the direction along the print swath axis with the nozzle arrays of printheads for printing the second primary color and the nozzle array of the printhead for printing yellow.
Abstract:
An apparatus and method for guiding recording media through a printer comprises a roller unit which is coupled to the printer and which comprises a plurality of roller wheels.
Abstract:
A method and system for compensating for nonfunctional ink jets in an ink jet printer. The ink-jet printer includes a printhead having a plurality of ink jets, each ink jet being assigned to print respective dots on a respective raster line of a recording medium in accordance with a print mask, wherein when an ink jet is detected as being defective, at least a portion of said print mask is replaced with a replacement mask such that one or more of the remaining ink jets of the plurality of ink jets compensates for the defective ink jet. The method includes: detecting when an ink jet is nonfunctional; and when an ink jet is determined to be nonfunctional, replacing at least a portion of the print mask with a replacement mask such that one or more of the remaining ink jets of the plurality of ink jets compensates for the nonfunctional ink jet.
