347 88, 347 84, 347 85, 347 99

Abstract:

A solid phase change ink melter assembly in a phase change ink image producing machine includes an array of a plurality of spaced apart fins, the array defining a top face for receiving the solid pieces of phase change ink, a bottom face for discharging melted ink, and opposite melter surfaces for melting the solid pieces in contact therewith. The assembly further includes a number of heat transfer devices extending through and in heat transfer contact with the plurality of fins, the heat transfer devices including a heating element for heating the device. The bottom edge of the fins defines a plurality of apexes which serve as drip points for molten phase change ink.

International Classification:

B41J 2/165

US Classification:

347 25

Abstract:

In an inkjet printing apparatus, a heater heats a drip bib that is located below a plurality of inkjets in a printhead to a temperature that melts ink collected on a surface of the drip bib. Pressurized air is directed toward the surface of the drip bib to remove the melted ink from the surface of the drip bib.

International Classification:

B41J 2/175

US Classification:

347 88

Abstract:

A pressurized ink delivery system having two delivery reservoirs in an inkjet printer enables a control system to alternate between the two reservoirs for printhead supply without coupling pressurized air from a delivery reservoir to a low pressure source of ink. Each delivery reservoir includes a conduit having an orifice that enables the pressure within a delivery reservoir to exit the reservoir before the ink delivery reservoir is fluidly connected to the low pressure source of ink for refilling of the delivery reservoir. By dropping the high pressure reservoir to atmosphere and then switching the seal actuators for the two reservoirs, the spray of ink is avoided.

US Classification:

347 88, 347 84, 347 85, 347 86

Abstract:

A method for delivering molten ink to a printing mechanism alternates between a first and second reservoir receiving molten ink from a receiving ink reservoir while providing ink from the other of the first and second reservoirs to a printing mechanism. The alternation of the two reservoirs is achieved with coordinated operation of two actuators operatively connected to two seal members.

US Classification:

347 33

Abstract:

A printhead wiper assembly includes an elongated member having a first and second wiper, a linkage, and an actuator. The linkage includes a clutch that enables the elongated member to move to a plurality of positions in response to the actuator activating a plurality of times. The sequence of positions enables first wiper and then the other wiper to contact the printhead face to remove purged ink from the face.
