Definitions

  • this proposed ink solvent system is subject to leaking PEG, particularly if the printer unit is turned on its side or upside down, which could easily occur during transportation, such as when moving one's office or home to a new location.
  • the PEG does not move quickly to the applicator, so during a series of rapid wiping strokes, the wipers may not receive a adequate coating of PEG.
  • the PEG ink solvent may need to be replenished to maintain optimum printhead servicing, and refilling the PEG reservoir is not easily accomplished with the proposed system.
  • FIGS. 4 and 5 illustrate a second embodiment of an ink solvent dispenser 120 constructed in accordance with the present invention, which may be substituted for the foam-filled dispenser 100 in the service station 80 of FIG. 2.
  • the dispenser 120 includes a shell or body 122 defining a reservoir chamber 124 therein, which may be constructed as described above and shown for shell 102 and reservoir 104.
  • the dispenser 120 has a back pressure device 125 within chamber 122 which may be constructed in a similar fashion to the back-pressure device used in inkjet cartridges for containing inkjet ink, such as the back-pressure device described in U.S. Patent No. 5,409,134, assigned to the present assignee, the Hewlett-Packard Company of Palo Alto, California.
  • the illustrated solvent dispensers 100, 120 are shown as being permanent fixtures within the service station 82, it is apparent to those skilled in the art that the service station frame 82 may be constructed with slots 140 or other latching devices to slideably or otherwise interchangeably receive the dispensers 100, 120. In this manner, the PEG fluid 110 may be periodically replaced by installing a new dispenser 100, 120 within the service station frame 82.
  • Such replacement schemes for consumables are well known to those in the inkjet art, and are commonly employed when installing replacement inkjet cartridges within inkjet printers, plotters, or other inkjet printing mechanisms.
  • these foam components 106, 108, 135 may be force-filled with ink solvent 110 by drawing a vacuum through these components to eliminate air within the pores, followed by introduction of the ink solvent, which would eliminate the need for plasma treating of components 106, 108, 135.
  • Filling of the reservoir 124 of applicator 120 may be easily accomplished by pouring ink solvent 110 through the snout opening 138 before assembling the applicator 135 into this opening of the snout 136.
  • shells 102, 122 may vary, depending upon the scheme used to apply the solvent 110 to printheads 70-76, or depending upon how the dispensers 100, 120 are installed in or attached to the service station frame 82, or alternatively, to the printer chassis 22. Indeed, while the exterior shape of the bodies 102, 122 may change, the operating principles illustrated herein remain substantially the same. For instance, rather than one dispenser 100 or 120 providing PEG 110 to all of the printhead wipers 90-96, separate shells 102, 122 may be used to apply solvent individually to each wiper 90-96.
  • two different shells may be used to apply solvent, indeed even different types of solvent, to wipers servicing printheads having different types of ink, such as one dispenser providing a die-based ink solvent, here to color wipers 92-96, and a separate dispenser applying a pigment-based solvent, here to the black wiper 90.
  • the illustrated service station 80 shows a rotary platform 85 for transporting the wipers 90-96 from the dispenser 100, 120, to the printheads 70-76, then to the scraper 114, it is apparent to those skilled in the art that other mechanisms may also be used for wiper movement, such as translational sliding platforms, or ramp-operated platforms that move in response to printhead movement provided by the carriage 45.
  • the dispensers 100, 120 are capable of storing a large volume of the ink solvent 110 in a very small space within printer 20, more than is currently possible in the proposed systems described in the Background section above. These dispenser systems 100, 120 advantageously facilitate more efficient packaging of the solvent fluid 110 by storing this fluid in a reservoir pool, rather than in an open foam pad as previously proposed. Furthermore, use of the porous applicators 108, 135 advantageously moves the ink solvent 110 more quickly from the reservoirs 104, 124 than in the proposed system described in the Background section above.
