    Abstract: A method and system for detecting a nonfunctional element in an ink jet printhead is disclosed. The ink jet printer system includes: a switching power supply, coupled to the inkjet printhead, for supplying power to the printhead; an output capacitor, coupled to an output of the switching power supply, for storing a dc voltage therein; a bleed resistor, coupled in parallel to the output capacitor, for discharging current from the output capacitor; an output shifting circuit, coupled to the switching power supply, for shifting the dc voltage level across the output capacitor between a low state and a high state; and a sensor, coupled to the output of the switching power supply, for detecting when the switching power supply is switching, wherein an element of the printhead is tested by measuring a test current discharging from the output capacitor when the element is activated and comparing the measured test current with a reference current which discharges from the output capacitor through the bleed resistor. The method includes: supplying regulated power to the printhead; storing the regulated power in a capacitor so as to provide a dc voltage across the capacitor; shifting the dc voltage level stored in the capacitor between a low state and a high state; measuring a test current discharging from the capacitor when an element of the printhead is activated; measuring a reference current discharging from the capacitor through a bleed resistor, when no elements of the printhead are activated; and comparing the measured test current with the reference current.

    Abstract: An apparatus and method for guiding recording media through a printer comprises a pinch roller which is pivotally coupled to the printer. The pinch roller may have a plurality of roller wheels. The degrees of freedom of the pinch roller allows the pinch roller to adjust its position and orientation with variations in the direction of motion of the recording medium as it is being fed through the printer.

    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, ii. advancing the print media, iii. printing the calibration target; 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.

    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: 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.
