Abstract
In accordance with an embodiment of the invention, a method of aligning plural staggered pens in a printer with a first pen and a second pen of the plural pens defining a macro-pen, the first and second pens being staggered, the method includes aligning the first and second pens of the macro-pen and aligning a third pen with the macro-pen.
Claims25
A method of aligning plural staggered pens in a printer, a first pen and a second pen of the plural pens, the first and second pens being staggered, the method comprising:
- defining a macro-pen including the first and second pens;
- aligning the first and second pens of the macro-pen;
- aligning a third pen with the macro-pen.
A method of aligning plural staggered pens in a printer, a first pen and a second pen of the plural pens, the first and second pens being staggered along a media advance axis, the method comprising:
- defining a macro-pen including the first and second pens;
- aligning the first and second pens of the macro-pen in a media advance axis;
- and
- aligning a third pen with the macro-pen in the media advance axis.
A method of aligning plural staggered pens in a printer, a first pen and a second pen of the plural pens defining a macro-pen, the first and second pens being staggered along a media advance axis, the method comprising:
- aligning the first and second pens of the macro-pen in the scan axis;
- and aligning the third pen with the macro-pen in the scan axis.
An article comprising:
- a storage medium having a plurality of machine-readable instructions, wherein when the instructions are executed, the instructions provide for:
- aligning a first pen and a second pen of a plurality of staggered pens in a printer, wherein the first pen and the second pen are staggered along a media advance axis and define a macro-pen;
- aligning a third pen with the macro-pen;
- and
- aligning a fourth pen with the macro-pen, the third and fourth pens being staggered along the media advance axis.
A pen alignment system comprising:
- a printer having plural pens, a first pen and a second pen of the plural pens defining a macro-pen, each pen of the plural pens having a plurality of nozzles configured to print a test block pattern, the test block pattern being arranged so as to allow determination of a first misalignment of the first and second pens of the macro-pen and to allow determination of a second misalignment of a third pen with the macro-pen;
- and
- a sensor for scanning the test block pattern to measure relative distances of the test block pattern to be employed in determining the first and second misalignment.
