Abstract

One aspect of the present invention is a method for adapting an ink jet printing system for receiving an alternate supply of ink. The ink jet printing system has an ink jet printhead responsive to control signals for selectively depositing ink on media. Also included in the printing system is a docking station configured for receiving a replaceable ink container. The replaceable ink container includes a fluid outlet that is arranged to establish fluid communication with a fluid inlet associated with the docking station upon insertion of the replaceable ink container into the docking station. The replaceable ink container provides a supply of ink from the replaceable ink container to the ink jet printhead. The method includes disconnecting. a fluid conduit extending between the fluid inlet and the ink jet printhead thereby interrupting the supply of ink from the replaceable ink container to the ink jet printhead. The method further includes connecting an alternate fluid conduit between the fluid inlet and the ink jet printhead. The alternate fluid conduit is in fluid communication with an alternate ink reservoir, wherein alternate ink is delivered from the alternate ink reservoir to the ink jet printhead.

Dependent claims

A method for adapting an ink jet printing system for receiving ink from an alternative non-pressurized supply of ink, the ink jet printing system including a scanning carriage, an ink jet printhead responsive to control signals for selectively depositing ink on media and a pressurized ink delivery system including an ink supply responsive to actuation by an actuator for providing a pressurized supply of ink to a fluid interconnect of the scanning carriage, wherein the ink jet printhead is removably engaged with the scanning carriage such that a fluid inlet portion of the ink jet printhead is removably connected to the fluid interconnect, and wherein the fluid interconnect is removably mounted on the scanning carriage and configured to fluidically couple with the fluid inlet portion of the ink jet printhead upon insertion of the printhead into the scanning carriage, the method comprising:

disconnecting the fluid inlet portion of the ink jet printhead from the fluid interconnect of the pressurized ink delivery system;
dismounting the fluid interconnect from the scanning carriage;
providing an alternative non-pressurized supply of ink that is not adapted for actuation by the actuator, the alternative non-pressurized supply of ink having a replacement fluid interconnect;
and
mounting the replacement fluid interconnect onto the scanning carriage, the replacement fluid interconnect so disposed and arranged on the scanning carriage to fluidically couple with the fluid inlet portion of the ink jet printhead upon insertion of the printhead into the scanning carriage;
and
connecting the fluid inlet portion of the ink jet printhead directly to the replacement fluid interconnect of the alternative non-pressurized supply of ink to provide alternative non-pressurized ink, different from the pressurized supply of ink, to the ink jet printhead.

providing an alternate ink reservoir having an alternate fluid conduit including a replacement fluid interconnect;
mounting the replacement fluid interconnect onto the scanning carriage;
and
connecting the fluid inlet portion of the ink jet printhead directly to the replacement fluid interconnect of the alternate fluid conduit such that alternate ink is delivered from the alternate ink reservoir to the ink jet printhead.
