Liquid ink printer having multiple pass drying

Claim 2

A liquid ink printer in which liquid ink is deposited, in response to image data, on a recording medium moving along a path and through a print zone, comprising: a liquid ink printhead, disposed adjacent to the path, to deposit liquid ink on the recording medium in response to the image data; a dryer, disposed adjacent to the path, defining a drying zone to dry the liquid ink deposited on the recording medium; a recording medium transport, disposed adjacent to said dryer, including a bidirectional electromover, to transport a portion of the recording medium along the path through the drying zone bi-directionally in multiple passes and through the printzone and the drying zone at a predetermined rate, said portion of the recording medium including areas of high ink coverage requiring additional drying; a controller, coupled to said recording medium transport, to move said portion of the recording medium through the drying zone in multiple passes; and an ink coverage device, coupled to said controller, to generate an output signal to said controller indicating a location of said portion of the recording medium including areas of high ink coverage, causing said controller to move said portion of the recording medium through the drying zone in multiple passes.

Claim 3

The liquid ink printer of claim 1, wherein said portion of the recording medium includes substantially an entirety of the recording medium.

Claim 4

The liquid ink printer of claim 1, wherein said recording medium transport comprises a belt transport, to move said portion of the recording medium through the drying zone in multiple passes.

Claim 5

A liquid ink printer in which liquid ink is deposited, in response to image data, on a recording medium moving along a path and through a print zone, comprising: a liquid ink printhead, disposed adjacent to the path, to deposit liquid ink on the recording medium in response to the image data; a dryer, disposed adjacent to the path, defining a drying zone, to dry the liquid ink deposited on the recording medium; a recording medium transport, disposed adjacent to said dryer, to transport a portion of the recording medium along the path through the drying zone in multiple passes and through the printzone and the drying zone at a predetermined rate, including a belt transport, said belt transport including a bidirectional electromover, to move said portion of the recording medium bi-directionally through the drying zone, said portion of the recording medium including areas of high ink coverage requiring additional drying; a controller, coupled to said recording medium transport, to move said portion of the recording medium through the drying zone in multiple passes; and an ink coverage device, coupled to said controller, to generate an output signal to said controller indicating a location of said portion of the recording medium including said areas of high ink coverage, causing said controller to move said portion of the recording medium through the drying zone in multiple passes.

Claim 6

A liquid ink printer in which liquid ink is deposited, in response to image data, on a recording medium moving along a path and through a print zone, comprising: a liquid ink printhead, disposed adjacent to the path, to deposit liquid ink on the recording medium in response to the image data; a dryer, disposed adjacent to the path, defining a drying zone, to dry the liquid ink deposited on the recording medium; a recording medium transport, disposed adjacent to said dryer, to transport a portion of the recording medium along the path through the drying zone in multiple passes and through the printzone and the drying zone at a predetermined rate, including a belt transport, said belt transport including a bidirectional electromover, to move said portion of the recording medium bi-directionally through the drying zone, said portion of the recording medium including areas of high ink coverage requiring additional drying; a controller, coupled to said recording medium transport, to move said portion of the recording medium through the drying zone in multiple passes; and an ink coverage device, coupled to said controller, to generate an output signal to said controller indicating a location of said portion of the recording medium including said areas of high ink coverage, causing said controller to move said portion of the recording medium through the drying zone in multiple passes.

Claim 7

The liquid ink printer of claim 4, wherein said belt transport includes a belt defining a plurality of apertures, the plurality of apertures to hold the recording medium to said belt upon an application of a vacuum therethrough.

Claim 8

The liquid ink printer of claim 5, wherein said belt transport includes a vacuum supply, disposed adjacent to said belt, to apply a vacuum through the plurality of apertures of said belt.

Claim 9

The liquid ink printer of claim 1, wherein said recording medium transport comprises a drum, to move said portion of the recording medium through the drying zone in multiple passes.

Claim 12

The method of claim 8, wherein said moving step comprises moving a portion of the recording medium through the drying zone at the predetermined rate.

Claim 13

The method of claim 9, comprising generating a first signal in response to said determined amount of liquid ink deposited on the recording medium, the first signal indicating that the determined amount of liquid ink deposited is capable of being dried in multiple passes through the drying zone.

Claim 14

The method of claim 10, wherein said moving step comprises moving a portion of the recording medium through the drying zone, the portion being substantially the entire recording medium.

Claim 15

The method of claim 10, wherein said moving step comprises moving the recording medium in a first direction and a second direction.

Claim 16

The method of claim 12, wherein said moving step comprises moving the recording medium in the first direction and the second direction with a belt.

Claim 17

The method of claim 12, wherein said moving step comprises moving the recording medium in the first direction and the second direction with a drum.

Claim 18

The method of claim 12, wherein said moving step comprises moving the recording medium in a single direction with a drum.
