Abstract
Abstract The present disclosure relates to an apparatus 54 for refilling a replaceable ink container 12. The ink container 12 has a top and bottom portion relative to a gravitational frame of reference. The replaceable ink container 12 further has a capillary storage member 40 disposed therein and a fluid outlet 36 disposed on the bottom portion. The apparatus for refilling includes a fluid interconnect 78 configured for insertion into the bottom portion to compress the capillary storage member 40.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
82 words
An apparatus 54 for refilling a replaceable ink container 12 having a capillary storage
member 40 disposed therein, the apparatus 54 for refilling comprising: a fluid interconnect 78 for compressing the capillary storage member 40; a backpressure measuring device 74 for measuring backpressure tending to draw
ink toward the capillary storage material 40; and wherein a quantity of ink is provided to the replaceable ink container 12 through
the fluid interconnect 12 based on backpressure determined by the backpressure
measuring device 74.
Claim 2
Dependent Claim
33 words
The apparatus 54 for refilling of claim 1 wherein the fluid interconnect 78 is a hollow
conduit that is inserted into the replaceable ink container 12 to compress the capillary
storage member 40.
Claim 3
Dependent Claim
81 words
The apparatus 54 for refilling of claim 1 further including an ink delivery device 56 for
providing the quantity of ink to the replaceable ink container 12 through a fluid outlet 36
in a bottom portion of the ink container 12, the ink delivery device configured to deliver
ink to the ink container 12 positioned in a bottom down orientation relative to the
gravitational frame of reference to provide ink to the capillary storage member 40
proximate the fluid outlet 36.
Claim 4
Independent Claim
156 words
An apparatus 54 for refilling a replaceable ink container 12, the ink container 12
having a top and bottom portion relative to a gravitational frame of reference, the
replaceable ink container 12 further having a capillary storage member 40 disposed
therein and a fluid outlet 36 disposed on the bottom portion, the apparatus 54 for refilling
comprising: a fluid interconnect 78 configured for insertion into the bottom portion to
compress the capillary storage member 40; means 74, 76 for determining an amount of ink to fill the replaceable ink
container 12; and an ink delivery device 56 for providing the determined quantity of ink to the
replaceable ink container 12 through the fluid interconnect 78, the ink delivery device 56
configured to deliver ink to the ink container 12 positioned in a bottom down orientation
relative to the gravitational frame of reference to provide ink to the capillary storage
member 40 proximate the fluid outlet 36.
Claim 5
Dependent Claim
43 words
The apparatus 54 for refilling of claim 4 wherein the ink delivery device 56 is
configured to provide ink to the ink container 12 so that air is displaced from the capillary
storage member 40 in a region proximate the fluid outlet 36.
Claim 6
Dependent Claim
36 words
The apparatus 54 of claim 4 wherein the means 74, 76 for determining an amount of
ink is a backpressure measuring device 74 for measuring backpressure tending to draw
ink toward the capillary storage material 40.
Claim 7
Independent Claim
72 words
A method for refilling a replaceable ink container 12 having a capillary storage
member 40 disposed therein for retaining ink, the method comprising: determining a quantity of ink to replenish the replaceable ink container 12 based
on backpressure tending to retain ink within the capillary storage member 40; and providing the determined quantity of ink to the replaceable ink container 12 so
that the capillary storage member 40 is replenished with ink.
Claim 8
Dependent Claim
28 words
The method of claim 7 wherein prior to determining a quantity of ink to replenish the
replaceable ink container 12 drawing ink from the capillary storage member 40.
Claim 9
Dependent Claim
67 words
The method of claim 7 wherein providing the determined quantity of ink to the
replaceable ink container 12 is performed through a fluid outlet 36 on a bottom portion of
the replaceable ink container 12 with the ink container 12 positioned in a bottom down
orientation relative to the gravitational frame of reference to provide ink to the capillary
storage member 40 proximate the fluid outlet 36.
Claim 10
Dependent Claim
43 words
The method of claim 7 wherein providing the determined quantity of ink to the
replaceable ink container 12 is performed to provide an ink front 62, 64 expands
outwardly into the capillary storage member 40 from a region proximate the fluid outlet
36.
