Problems solved by technology

[0002] Although many different types of thermal printheads are commonly used in commercial and home printers, known printheads have common disadvantages
For example, when a thermal printhead that is claimed to be defective is returned to the manufacturer or distributor, it is often difficult to determine whether the thermal printhead is truly defective or a printhead that has been misused
Thermal printheads are designed for specific operating conditions and depending on the printer in which they are installed, these thermal printheads may fail due to use outside of design parameters
Also, it is difficult to determine how much actual usage the consumer got from the printhead prior to failure

Embodiment Construction

[0009] Specific terms are used in the following description for convenience only and are not limiting. The term "linear printing" means "linear printing by a print head based on printing with a specific resolution". As used in the claims and corresponding parts of the specification, the words "a" and "an" are defined to include one or more of the indicated item unless expressly stated otherwise.

[0010] Referring to FIGS. 1-3 (like numerals refer to like elements in all of these figures), an exemplary embodiment of a printing system including the usage monitor of the present invention is shown and generally designated 10 . Briefly, printing system 10 uses data acquisition unit ("DAU") 20 to continuously monitor actual printhead usage. Preferably, the DAU 20 periodically scans all printhead functions to obtain periodic data regarding the printhead's operating environment and the state of the printhead.

[0011] The printing system 10 shown in FIG. 1 preferably includes a the...

Abstract

The present invention provides a thermal print head usage monitoring sensor and method for using the sensor. A data acquisition unit for use in monitoring print head activity and collecting corresponding data for product analysis is disclosed. A method of using the data acquisition unit is also disclosed.

Description

technical field [0001] The present invention relates generally to printhead monitors, and more particularly to a thermal printing system and method for monitoring thermal printhead usage. Background technique [0002] Although many different types of thermal printheads are commonly used in commercial and home printers, known printheads have common disadvantages. For example, when a thermal printhead that is claimed to be defective is returned to the manufacturer or distributor, it is often difficult to determine whether the thermal printhead is truly defective or a printhead that has been misused. Thermal printheads are designed for specific operating conditions, and depending on the printer in which they are installed, these thermal printheads may fail due to use outside of design parameters. In addition, it is difficult to determine how much actual usage the customer got from the printhead prior to failure. [0003] It would be advantageous to have a monitor or printing ...
