Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
57 words
A test page produced by a laser printer, the laser printer having at least one primary color, the test page for setting a density level of the laser printer for the at least one primary color, the test page comprising a dot gain test pattern (10) of the at least one primary color of the laser printer.
Claim 2
Dependent Claim
39 words
The test page of claim 1 wherein the dot gain test pattern (10) includes a self-indicating pattern indicative, without reference to any other source, of the density level of the laser printer for the at least one primary color.
Claim 3
Dependent Claim
79 words
The test page of claim 1 wherein the dot gain test pattern (10) includes: (a) a stable pattern having a color density which is stable with respect to changes in operating conditions of the laser printer; and, (b) a sensitive pattern having a color density which is sensitive to changes in the operating conditions, wherein the sensitive pattern in reference to the stable pattern indicates the density level of the laser printer for the at least one primary color.
Claim 4
Dependent Claim
79 words
The test page of claim 3 wherein the stable pattern includes a uniform coarse dot pattern (15), and wherein the sensitive pattern includes a gradient (20) of fine dot densities, the gradient (20) printed adjacent to the coarse dot pattern (15), wherein a correct density level of the laser printer for the at least one primary color is indicated when a mid-spectrum area (25) of the fine dot gradient (20) appears to blend into the coarse dot pattern (15).
Claim 5
Dependent Claim
13 words
The test page of claim 1 further including a gray balance test pattern.
Claim 6
Independent Claim
44 words
A system for setting a color density level of a laser printer, the laser printer having at least one primary color, the system comprising means for producing a dot gain test pattern (10) of the at least one primary color of the laser printer.
Claim 7
Dependent Claim
56 words
The system of claim 6 wherein the dot gain test pattern (10) includes a plurality of portions, wherein each of the plurality of portions, in reference to each other, provides a self-indicating pattern indicative, without reference to any other source, of the color density level of the laser printer for the at least one primary color.
Claim 8
Dependent Claim
79 words
The system of claim 6 wherein the dot gain test pattern (10) includes: (a) a stable pattern having a color density which is stable with respect to changes in operating conditions of the laser printer; and, (b) a sensitive pattern having a color density which is sensitive to changes in the operating conditions, wherein the sensitive pattern in reference to the stable pattern indicates the color density level of the laser printer for the at least one primary color.
Claim 9
Independent Claim
87 words
A method for setting a color density level of a laser printer, the laser printer having at least one primary color, the method comprising: (a) printing a dot gain test pattern (10) of the at least one primary color of the laser printer; (b) adjusting the color density level of the laser printer for the at least one primary color based on visual observation of the dot gain test pattern (10); and, (c) repeating steps (a) and (b), as necessary, until the color density level is correct.
Claim 10
Dependent Claim
43 words
The method of claim 8 further including: (a) printing a gray balance test pattern; and, (b) further adjusting the color density level of the laser printer for the at least one primary color based on visual observation of the gray balance test pattern.
