Abstract
Abstract The present invention is a replaceable ink container for use with a printing apparatus. The printing apparatus of the type having out of ink detection. The replaceable ink container includes a fluid reservoir having an outlet. The outlet is configured for connection to a fluid inlet associated with the printing apparatus. Also included in the replaceable ink container is an actuator engagement device for engaging an actuator associated with the printing apparatus. The actuator is of the type that is movable between a first position wherein an out of ink signal is generated and a second position. The actuator engagement device is disposed and arranged to engage the actuator to prevent movement of the actuator from the second position to the first position thereby preventing the out of ink signal.

Claim 5
Dependent Claim
14 words
The replaceable ink container of claim 1 wherein the actuator engagement device is fixed.
Claim 6
Dependent Claim
21 words
The replaceable ink container of claim 1 wherein the actuator engagement device is a leading edge of a variable volume chamber.
Claim 7
Dependent Claim
17 words
The replaceable ink container of claim 1 wherein ink delivered by the ink container is substantially non-pressurized.
Claim 8
Dependent Claim
34 words
The replaceable ink container of claim 1 further including a sensor, the sensor associated with the actuator for monitoring the position of the actuator to detect when the actuator is in an extended position.
Claim 9
Dependent Claim
24 words
The replaceable ink container of claim 1 further including an ink usage monitor for determining an out of ink condition based on ink usage.
Claim 10
Independent Claim
126 words
A method for providing ink to a printing apparatus having a fluid inlet for receiving ink and an actuator movable between a first position wherein an out-of-ink signal is generated and a second position, movement of the actuator produces an engagement with an expandable chamber associated with an ink container to bias the expandable chamber to supply ink to the fluid inlet, the method comprising: coupling fluidically a fluid outlet in fluid communication with a supply of ink to the fluid inlet to allow ink to pass from the supply of ink to the fluid inlet; and engaging the actuator associated with the printing apparatus to prevent movement of the actuator from the second position to the first position thereby preventing an out of ink signal.
Claim 11
Independent Claim
126 words
A method for providing ink to a printing apparatus having a fluid inlet for receiving ink and an actuator movable between a first position wherein an out-of-ink signal is generated and a second position, movement of the actuator produces an engagement with an expandable chamber associated with an ink container to bias the expandable chamber to supply ink to the fluid inlet, the method comprising: coupling fluidically a fluid outlet in fluid communication with a supply of ink to the fluid inlet to allow ink to pass from the supply of ink to the fluid inlet; and engaging the actuator associated with the printing apparatus to prevent movement of the actuator from the second position to the first position thereby preventing an out of ink signal.
Claim 12
Dependent Claim
38 words
The method for providing ink to a printing apparatus of claim 9 wherein fluidically coupling the fluid outlet further includes pressurizing ink within the supply of ink to provide a pressurized supply of ink to the fluid inlet.
