    摘要: A sensor configuration for use in detecting ink droplets ejected from an ink drop generator is provided. The sensor configuration includes a sensing element configured to receive a biasing voltage which creates an electric field from the sensing element to the ink drop generator. The sensor configuration also includes a sensing amplifier coupled to the sensing element, whereby the sensing element in imparted with an electrical stimulus when at least one ink droplet is ejected in the presence of the electric field, and thereafter passes in close proximity to the sensing element without substantially contacting the sensing element. Sensor configurations with a separate electrically biasing element which may or may not contact the ink droplets are also provided. Additionally, a printing mechanism having such sensor configurations and a method of making ink drop detection measurements are also provided.

    摘要: Determining inkjet printer pen turn-on voltages is disclosed. An inkjet printer has a number of pens, and a number of sets of nozzles in each pen. Each set of nozzles of a pen is fired at each of a number of voltages, to obtain a voltage-value curve for each set of nozzles. A nozzle turn-on voltage for each set of nozzles is determined based on a maximum slope of its voltage-value curve. The turn-on voltage for each pen is determined based on the nozzle turn-on voltages of the voltage-value curves for its sets of nozzles.

    摘要: An ink cartridge of a printer includes first and second electrodes on opposite sides of an ink reservoir. Level of ink in the reservoir may be measured by applying a sense signal to the first electrode, detecting a signal at the second electrode, extracting DC content of the detected signal, and using the DC content to determine the ink level.

    摘要: A method of producing and using photo media to print a glossy, photo-quality image. The image is printed onto the back of a coated transparent base. Thereafter, an opaque backing is applied to cover the printed image. The resulting print is viewed from the front, which provides the photo-quality, attractive appearance primarily because of the substantial gloss depth and uniformity attributable to the transparent base. The transparent base and backing protect the ink-receiving coating and make the resulting print very durable. The image is light fast because the ink is sandwiched between the transparent base and the backing, thereby sealing the ink from oxygen. In a preferred embodiment of the present invention, the backing is applied as a liquid using substantially the same mechanism as used for printing the image.

    摘要: A bulldozer-type cleaning system is provided for removing ink residue from an electrostatic drop detecting sensor which detects ink droplets contacting the detector. A scraper head scrapes the ink residue from the sensor, and then contacts a flexible, compliant cleaning member, illustrated as a coil spring. The spring is secured at each end and is stretched when pushed by the scraper head. This stretching flexation allows the spring to trap the ink residue between the coils. As the scraper head retracts, the resulting contracting flexation of the spring squeezes the ink residue from between the coils. Any ink residue remaining on the coils dries and then flakes off the coils when the spring is stretched again during the next cleaning stroke of the scraper head. An inkjet printing mechanism having such a cleaning system, and a method of cleaning a sensor are also provided.
