摘要:
An inkjet printer (1) for use in a network environment comprising: a body (2) having; at least one media input tray (4) for supplying one or more sheets of media for printing; a print engine (3) for printing an image on a sheet of media, said print engine (3) including a removable pagewidth inkjet printhead; and a delivery passage for delivering a sheet of media from the at least one media input tray (4) to the print engine (3) for printing; wherein the base of the body (2) is configured to receive at least one auxiliary media input tray for supplying one or more sheets of media for printing, and an opening is provided in said base to receive a sheet of media from said auxiliary media input tray for delivery to the print engine via said delivery passage.
摘要:
A digital micro-mirror device comprising an array of micro-mirror assemblies positioned on a substrate. Each micro-mirror assembly comprises: a mirror spaced apart from the substrate; a stem supporting the mirror; and first and second electrodes positioned on either side of the stem. The stem is comprised of a resiliently flexible material, such that the mirror can tilt either towards the first electrode or towards the second electrode by an electrostatic force. The digital micro-mirror device may be used in data projectors and the like.

A printhead assembly includes a molded ink manifold, a plurality of printhead integrated circuits, and an adhesive film sandwiched between the ink manifold and the printhead integrated circuits. A manifold bonding surface of the molded ink manifold includes a polymer coating. The polymer coating plugs fissures resulting from a molding process used to mold the ink manifold.
摘要:
An inkjet printer that has a printhead with an array of ejection devices for ejecting drops of liquid onto a media substrate. Each of the ejection devices having a chamber for holding liquid, a nozzle in fluid communication with the chamber and a heater positioned in the chamber for contact with the liquid such that resistive heating of the heater generates a vapour bubble that ejects a drop of the liquid through the nozzle. The printer also has a controller for receiving print data and generating drive pulses to energize the heaters in accordance with the print data. The controller increases the drive pulse energy during the printhead lifetime.
摘要:
A microfluidic system comprising an integrated circuit having a bonding surface bonded to a polymeric microfluidics platform. The microfluidic system comprises one or more microfluidics devices controlled by control circuitry in the integrated circuit. At least one of the microfluidic devices comprises a MEMS actuator positioned in a MEMS layer of the integrated circuit. The MEMS layer is covered with a polymeric layer which defines the bonding surface of the integrated circuit.
摘要:
A method of fabricating a film for attachment of one or more printhead integrated circuits to an ink supply manifold. The method comprises the steps of: (a) providing an adhesive polymeric film, the film being comprised of one or more photopatternable materials; (b) exposing predetermined regions of the film through a mask; and (c) developing the film to define a plurality of ink supply holes.
摘要:
A method of fabricating an apertured polymeric film. The method comprising the steps of: (a) masking a polymeric film with a first mask having first laser transmission zones defined therein; (b) laser-ablatmg first apertures through the polymeric film using the first mask; (c) masking the film with a second mask having second laser transmission zones defined therein, each second zone being aligned with a corresponding first aperture, and each second zone having greater perimeter dimensions than the corresponding first aperture; and (d) reaming the first apertures by laser-ablatmg the polymeric film using the second mask, the reamed first apertures defining second apertures m the film.
摘要:
An inkjet printer comprising: a printhead comprising a nozzle plate having a plurality of nozzle openings defined therein, said nozzle plate comprising a first relatively hydrophilic layer and a second relatively hydrophobic layer, said second layer defining an ink ejection face for said printhead; and a capper having a planar capping surface, said capper being moveable between a first position in which said capper is disengaged from said printhead and a second position in which said capping surface sealingly engages with said ink ejection face wherein, in said second position, a meniscus of ink contained in each nozzle opening is pinned at an interface between said first and second layers, such that a microwell is defined between said capping surface and said meniscus.
摘要:
A phthalocyanine phthalocyanine salt suitable for formulation in a solvent-based or oil-based ink vehicle is disclosed. The phthalocyanine comprises one or more sulfonate groups and a counterion of at least one sulfonate group is an ammonium cation comprising at least 15 carbon atoms. Ammonium salts of sulfonated gallium naphthalocyanines exemplify such phthalocyanine salts. Formula (5)
