Abstract
Abstract A printer (10) with mixed base resolution capabilities, having a higher resolution monochrome component such as black and lower resolution components such as cyan, magenta and yellow. The different resolution components are integrated into the same printing mechanism for composite printing of higher resolution black and lower resolution color at the same time. For increased throughput, a higher resolution black printhead (98) has a wider swath.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
82 words
A mixed resolution printer (10) comprising: a frame for holding media in a print zone; a carriage (50) supported on said frame to be positioned adjacent to said print zone; a first printhead (64) having a first print resolution; a second printhead (40) having a second print resolution different from said first print resolution; and means for mounting said first and second printheads on said carriage for composite printing by said first and second printheads on the media in said print zone.
Claim 2
Dependent Claim
22 words
A printer according to claim 1 wherein said first printhead includes a black printhead and said second printhead includes a color printhead.
Claim 3
Dependent Claim
23 words
A printer according to claim 2 wherein said second printhead includes a color component selected from cyan, magenta, yellow, red, green and blue.
Claim 4
Dependent Claim
20 words
A printer according to claim 2 or 3 wherein said black printhead has a higher resolution than said color printhead.
Claim 5
Dependent Claim
22 words
A printer according to claim 2, 3 or 4 wherein said black printhead has a wider printing swath than said color printhead.
Claim 6
Dependent Claim
50 words
A printer according to claim 1 wherein said first print means is a printhead having a first nozzle pitch, and said second print means is a printhead having a second nozzle pitch, with said first nozzle pitch less than said second nozzle pitch as measured in said media advance axis.
Claim 7
Dependent Claim
25 words
A printer according to claim 1 wherein said first printhead includes a color component which is different from a color component of said second printhead.
Claim 8
Dependent Claim
38 words
A printer according to any preceding claim wherein said mounting means mounts said first and second printheads in relative positions along the media advance axis in order to produce at least partially overlapping print swaths from said printheads.
Claim 9
Dependent Claim
38 words
A printer according to claim 1 wherein said first printhead has a first print resolution greater than said second print resolution of said second printhead, with said first printhead having a wider print swath than said second printhead.
Claim 10
Dependent Claim
25 words
A printer according to claim 9 wherein said mounting means mounts said second printhead to be in completely overlapped printing alignment with said first printhead.
