Filed:

Jul 10, 2002

Appl. No.:

10/192597

Inventors:

Adam J. Ahne - Lexington KY
Ricky E. Robbins - Harrodsburg KY
Michael K. Webb - Winchester KY

Assignee:

Lexmark International, Inc. - Lexington KY

International Classification:

B41J 29393

US Classification:

347 19, 347 14, 347 5

Abstract:

The invention is drawn to a test circuit for an ink jet printer which measures the voltage decay over time. Specifically, the test circuit utilizes a known resistor connected to the power source (voltage) and the printer. The printer functions as a capacitor to complete the test circuit as an RC circuit. After isolating the power source from the test circuit, the voltage decay is monitored to indicate the presence of a short circuit.

International Classification:

B41J023/00

US Classification:

347 5, 399 88, 323901

Abstract:

A power control circuit is connected between a power source and an electronic controller in a device such as a printer and includes a latchable power delivery state for delivering power to an electronic controller of the device. Temporary closure of a switch latches the power control circuit in its power delivery state. The electronic controller subsequently detects temporary closure of the switch and responds with an output signal that unlatches the power control circuit into a power non-delivery state. The power control circuit may include an associated kick-start circuit portion for causing the power control circuit to latch into its power delivery state in response to initial application of power by the power source.

Assignee:

Lexmark International, Inc. - Lexington KY

International Classification:

B41J 3/36
B41J 29/13

US Classification:

347109, 347108

Abstract:

A hand-operated printer includes a body, a printhead mounted to the body, a target sight mounted to the body, and a display device mounted to the body. The display device is configured to display an image and a representation of the target sight in relation to the image, and wherein the relation between the representation of the target sight and the image that are displayed on the display device corresponds to a relationship between the target sight and a print position for the image.

Assignee:

Lexmark International, Inc. - Lexington KY

International Classification:

B41J 29/38

US Classification:

347 14, 347 7

Abstract:

A method of operating an ink jet apparatus to print a print job on print media with a printhead having a supply of ink and an initial printhead operating frequency is disclosed. The method comprises receiving the print job for printing on the media, determining the volume of the supply of ink, comparing the volume of the supply of ink to a predetermined level, calculating a revised printhead operating frequency in response to the comparison, and operating the printhead at the revised printhead operating frequency to print the print job.
