  • Publication number: 20050168522
    Abstract: An inkjet printhead squeegee is split on one side so that its wiping force on a printhead is highest on the front stroke and much lighter on the backstroke when the surface is dry. Alternatively, the split can be arranged so that the front stroke is light enough to leave the printhead wet, and then the backstroke is much firmer to completely squeegee the printhead dry. The result is high pressure strokes on a dry printhead are avoided.

  • Publication number: 20050134634
    Abstract: A modular service station assembly for use with an inkjet printer having a housing with front and rear ends having a print zone and one or more carriage assemblies adapted to accommodate at least one print cartridge having a print head. The service station assembly has at least one ink spittoon. The service station also includes a wiping station having at least one wiper for cleaning the print head. The at least one ink spittoon and the wiping station are separately disposed to one side of the print zone. The service station further includes a capping station having at least one cap for sealing the print head disposed within the print zone. These discrete modules are arranged to minimize the width of the printer housing.

  • Publication number: 20050007411
    Abstract: A printer comprises an inkjet printhead capping assembly that raises up on an elevator to seal the printheads between uses. Such sealing prevents drying of the ink on the printhead nozzles that would otherwise cause clogging and poor operation. The elevator rides up and down on four ramps located at each corner of a cap carriage platform. A rack and pinion gear pushes pins riding on each ramp laterally to translate into the needed up and down elevator motion.

  • Publication number: 20050006835
    Abstract: A mobile, color printer capable of printing on letter-size plain paper and standard-size photo paper has a fold-up paper feeder that acts as a cover during travel. Such also serves as a storage tray for several sheets of paper to allow automatic feeding from a vertical stack. A slotted door hinged to the back of the printer, and under the hinges for the fold-up paper feeder/cover, can be flipped up or down. In the down position, a slot on the right side guides the user to feed in photo paper in the correct location. In the up position, letter-size plain paper has full-width access to the printing mechanism, and a sliding adjustable guide on the left allows letter, A4, and other size papers to be lightly corralled on both sides.

  • Patent number: 4677937
    Abstract: A carrier for dual-in-line packages to be wave soldered, comprises a frame with tracks into which the packages can be slid. The tracks are defined by aligned upper and lower "U"-shaped channel members providing rails. Each track is defined between adjacent pairs of upper and lower members. Gates at either end of the tracks control movement of the packages into or out of the carrier. The carrier can be loaded and unloaded by means of apparatus including an inclined ramp on which the carrier can be releasably located, the packages being fed into the top of the ramp to fill the carrier, and sliding to the bottom of the ramp to empty the carrier of soldered packages prior to re-filling. Movement of the packages down the ramp is controlled by gates.
