Abstract
A method includes generating a machine readable code using each ink color implemented at a printer, printing the machine readable code on a first side of the medium, analyzing the machine readable code printed on the first side of the medium at a verification unit and detecting a side mismatch if the verification unit does not verify the machine readable code printed on the first side of the medium.
Claims28
A method comprising:
- generating a machine readable code having multi-color marks including each ink color implemented at a printer;
- printing the machine readable code on a first side of a medium;
- analyzing the machine readable code printed on the first side of the medium at a verification unit;
- and
- detecting an error if the verification unit does not verify that each color of the multi-color marks is readable.
A printer comprising:
- a first print head to print a machine readable code on a first side of a medium;
- and
- a side verification unit to generate the machine readable code having multi-color marks including each ink color implemented at a printer, analyze the machine readable code printed on the first side of the medium and detect an error if the verification unit does not verify that each color of the multi-color marks is readable.
An article of manufacture comprising a machine-readable medium including data that, when accessed by a machine, cause the machine to perform operations comprising:
- generating a machine readable code having multi-color marks of including each ink color implemented at a printer;
- printing the machine readable code on a first side of a medium;
- analyzing the machine readable code printed on the first side of the medium at a verification unit;
- and
- detecting an error if the verification unit does not verify that each color of the multi-color marks is readable.
