Abstract
A method for forming a combined printhead alignment pattern includes printing a row of spaced blocks which accommodates both the collection of multiple printhead alignment data pertaining to printhead alignment as between a plurality of printheads and the collection of bi-directional alignment data pertaining to bi-directional alignment for at least one particular printhead, each of the blocks being printed in a single scan direction, but with some of the blocks being printed in a first scan direction and a remainder of the blocks being printed in a second scan direction opposite to the first scan direction.

A method for forming a combined printhead alignment pattern, comprising printing a row of spaced blocks which accommodates both the collection of multiple printhead alignment data pertaining to printhead alignment as between a plurality of printheads and the collection of bi-directional alignment data pertaining to bi-directional alignment for at least one particular printhead, each of said blocks being printed in a single scan direction, but with some of said blocks being printed in a first scan direction and a remainder of said blocks being printed in a second scan direction opposite to said first scan direction.
A method for forming a combined printhead alignment pattern, comprising printing a row of spaced blocks which accommodates both the collection of printhead skew data and the collection of bi-directional alignment data pertaining to bi-directional alignment for at least one printhead, each of said blocks being printed in a single scan direction, but with some of said blocks being printed in a first scan direction and a remainder of said blocks being printed in a second scan direction opposite to said first scan direction.
A method for use in performing printhead alignment in an imaging apparatus;
- comprising:
- forming a combined printhead alignment pattern by printing a row of spaced blocks which accommodates collection of printhead alignment data pertaining to a plurality of printhead alignment types;
- and
- scanning said row with a scanner to obtain said printhead alignment data pertaining to said plurality of printhead alignment types.
