Method for determining enhanced printing functions on a hand-held inkjet printer having one or more optical sensors configured to measure speed and distance across the page. Collecting a first frame of individual pixel data, mapping the first frame of individual pixel data into a pixel map memory, processing the first frame of individual pixel data to perform additional print quality features. These additional features can be categorized in three main categories: 1) sensing non-printing elements, 2) sensing pre-printed elements, and 3) sensing print elements.

Methods for improving print quality in a hand-held printer

Methods and system for validating facsimile communications by ensuring that each detected facsimile calling tone is actually a facsimile calling tone that was generated by a sending facsimile device. The method can include establishing a connection between a sending facsimile device and a receiving facsimile device, which was initiated by either the sending facsimile device or the receiving facsimile device. The connection can be utilized for at least one of facsimile communication, voice communication, and a combination of facsimile communication and voice communication. The method can also comprise switching the receiving facsimile machine from a voice-capable mode to a facsimile mode once at least one facsimile calling tone is detected after a first facsimile calling tone is detected while the receiving facsimile device in the line monitoring mode.

Method and apparatus for validation of facsimile communication

Methods and apparatus include a handheld printer manipulated back and forth by an operator during use to print an image. An inkjet printhead of the printer has a plurality of fluid firing actuators arranged in a substantial column. A controller communicates with the printhead to identify active actuators given to fire at a particular time during use to print the image. However, to prevent unsightly print quality from occurring during overlapping adjacent print swaths, for example, certain of the identified actuators are prevented from firing. Especially, actuators in the column further from a center of the column fire less frequently than those closer to the center. A position sensor is also used to locate the printhead relative to the image. The controller correlates the position to the printhead and actuators and fires the active actuators or not.

Handheld printer minimizing printing defects

A hand-held micro-fluid ejection device for ejecting a fluid onto a substrate surface in a plurality of physical orientations between the ejection device and a substrate surface, and methods for controlling the geometric accuracy of printing using a hand-held printing apparatus. Various spatial and dynamic orientations of the ejection device are measured, such as rotation angle, yaw angle, and velocity and acceleration vectors. Threshold limits are established for the orientations and printing is disabled if the measured values exceed the threshold limits.

A phone jack connection detection system and method of operating the same, including a phone jack circuit having a data access arrangement circuit in communication with at least two pins, a stimulus input in communication with the phone jack circuit, the stimulus input being adapted to communicate a stimulus to the phone jack circuit, and a detection circuit in communication with the phone jack circuit, the detection circuit being adapted to detect a response of the phone jack circuit to the stimulus and notify a user of the status of the connection.

A method for printing incoming facsimiles assigns a print-priority number to a plurality of known facsimile origination identification numbers, wherein the print-priority number is different for at least two of the plurality. The method also identifies the facsimile origination identification number of incoming facsimiles. The method also stores the incoming facsimiles if from a known facsimile origination identification number assigned one of at least two different print-priority numbers. The method also prints the stored facsimiles in an order based at least on their corresponding print-priority numbers.

Method for printing incoming facsimiles

Method of printing from a printer, where the printer includes one or more maintenance firings from a printhead nozzle. Formatting a print job to be printed in determining which nozzles on a printhead require maintenance during printing of the print job. Modifying the formatted print job to include one or more maintenance firings for the nozzles requiring maintenance.

Maintenance on a hand-held printer

A method for providing a virtual replenishing of a supply item with an imaging substance includes the steps communicating to a database a first serial number associated with a first supply item; comparing the first serial number with a plurality of serial numbers stored in the database; receiving from the database one of a first data indicating non-correspondence between the first serial number with one of the plurality of serial numbers and a second data indicating correspondence between the first serial number with one of the plurality of serial numbers, wherein the second data includes a verification key; and if the verification key corresponds to the first key stored in the memory associated with the first supply item, then performing the step of allocating at least a portion of a surplus amount of the imaging substance contained in the first supply item for use.

Method for providing imaging substance for use in an imaging device via a virtual replenishment

A method for carrying out predetermined actions by a telecom receiving device. A predetermined answer string is entered and stored in a memory portion of a receiving telecom device. Incoming calls are checked for appropriateness. Accepted incoming calls are monitored for a predetermined event. If the predetermined event is detected, a set of steps are accomplished in accordance with the previously stored answer string. The receiving telecom device then resumes normal operation after completing the actions represented by the answer string.

An apparatus for perforating a sheet of print media having a front side and a back side includes a printhead carriage for carrying a printhead. A perforator carriage carries a perforation forming mechanism. An isolation damper having elastic, vibration absorbing, characteristics couples the printhead carriage to the perforator carriage.

Perforation forming mechanism for use in an imaging apparatus

An apparatus for perforating a sheet of media includes a perforation forming mechanism including at least one perforation device. The perforation forming mechanism is configured to drive the perforation device through the sheet of media to extend through the sheet of media by a distance.

The invention provides a system and method for detecting the presence of an ink jet printhead when a printhead controller fails to properly identify an installed printhead using a printhead identification device. The system includes a printhead including heater resistors and control elements, and a controller connected to the printhead via address and data lines. When the controller fails to properly identify an installed printhead, the controller operates to bias the control elements in a predetermined manner via at least one address line, detect a signal via the data lines, and generate a signal indicative of the presence of the installed printhead.

System and method for ink jet printhead detection

A media eject system for a printer having an output tray includes an edge wing for supporting an edge of media exiting the printer, the edge wing movable between support and non-support positions. A kicker engages a trailing edge of media and moves the media into the tray. The kicker is movable between a retracted position and an extended position and operable to move the media into the tray by movement of the kicker from the retracted position to the extended position. A controller determines a print condition including at least one of a media type and a print format, and adjusts a position of the wing dependent upon the print condition.

Multi-function media eject system in an ink jet printer

A multi-function media eject system and method for operation particularly useful for ink jet printers. At the start of a print job, the media type and print format are determined. If the media is either banner paper or envelope, or if the print format is draft quality printing, wings and kickers of the eject system are disabled, so the media exits the printer without support from the wings or influence from the kickers.
