US Patent:

6325557, Dec 4, 2001

Filed:

May 10, 1999

Appl. No.:

9/309391

Inventors:

Gary M. Klinefelter - Eden Prairie MN
Gary A. Lenz - Eden Prairie MN

Assignee:

Fargo Electronics, Inc. - Eden Prairie MN

International Classification:

B41J 3100

US Classification:

400240

Abstract:

A ribbon for a thermal printer has a series of frames of different colors in a sequence that are correlated to the position of cards to be printed. The ribbon has indexing marks for each frame and also indicators for each repeating sequence of frames. The index marks are arranged in a line across the ribbon and the marks can be coded to individually indicate the color or other characteristic of the frame associated with the line of index mark. This information is received by a controller to control various printer functions.

US Classification:

400208, 400692, 34682531, 34682554, 347177, 235380

Abstract:

A printer for printing onto a substrate includes a substrate feed mechanism configured to secure the substrate during printing and a print mechanism configured to print on the substrate. A transceiver is configured to transfer power through a non-physical link to a radio frequency (RF) circuit carried on a printer supply to thereby power the RF circuit. The transceiver also responsively receives printer supply data through a non-physical link from the RF circuit.

International Classification:

G06F 1300

US Classification:

358 116, 358 117, 711100, 711132

Abstract:

A printer for printing on a substrate includes an input configured to receive data, a print mechanism configured to print an image on the substrate, and a controller coupled to the input and the print mechanism configured to actuate the print mechanism in response to the input. The controller includes a microprocessor and memory containing a multi-threaded operating system and programming instructions for the microprocessor. The memory implements a plurality of stacks, each stack related to a thread. The programming instructions include a plurality of separate programs and the operating system executes each program as a separate thread and stores information related to each thread on a respective stack in the memory.

International Classification:

B41J 201

US Classification:

347104

Abstract:

An ink jet card printer is disclosed that includes an ink jet printhead and a transport mechanism. The ink jet printhead is adapted to print on portions of a surface of a card that are presented in a print position along a print path. The transport mechanism includes at least one cantilevering mechanism that is positioned to a side of the print position along the print path. The cantilevering mechanism is adapted to unobstructively present the surface of the card to the printhead in the print position.

Fargo Electronics, Inc. - Eden Prairie MN

International Classification:

B41J 328

US Classification:

400 48, 101 35, 101126

Abstract:

The present invention is directed to a carrier for use with a printer that can support irregularly shaped substrates having a top surface. The carrier includes first and second planar members. The first planar member has top and bottom surfaces, a thickness, and an inner edge that conforms to an irregularly shaped outer edge of a substrate. The second planar member has a top surface that is coupled to the bottom surface of the first planar member. A recess, defined by the inner edge of the first planar member and the top surface of the second planar member, is adapted to receive the substrate such that top surfaces of the substrate and the first planar member are coplanar.

International Classification:

G01L 1100

US Classification:

702140, 702 98, 702130, 702183

Abstract:

A pressure transmitter with an output predicting the magnitude of error in the pressure transmitters output. A pressure sensor is adapted to sense a process pressure. A controller coupled to the pressure sensor generates a transmitter output representing the process pressure. A memory stores predetermined data predicting magnitudes of transmitter output error as a function of cumulative excessive sensor output levels, and also stores a record of cumulative excessive sensor output levels. The controller calculates a predicted present magnitude of transmitter output error as a function of the accumulated record and the predetermined data, and generates the prediction output.

International Classification:

G05B 1302

US Classification:

700 51, 700275

Abstract:

An identification card printer for printing an identification card includes a print mechanism configured to print onto the identification card. A process signal input is configured to receive a process signal related to operation of the identification card printer. A memory contains a nominal process signal statistical parameter and a rule. A microprocessor is coupled to the memory and configured to receive the process signal from the process signal input and calculates a statistical parameter of the process signal. The microprocessor compares the calculated statistical parameter to the nominal statistical parameter based upon the rule and responsively provides an event output as a function of the comparison. The event output is related to an occurrence of an event during operation of the identification card printer.
