摘要： An environmental condition detection system for a hardcopy device, such as an inkjet printing mechanism, includes an environmental condition sensor having an optical property which changes in response to a change in an environmental condition, for instance humidity or temperature. The system also has an optical sensor which detects changes in the optical property and generates a signal for a controller that responds by changing an operating parameter of the hardcopy device. A hard copy device having such a environmental condition detection system is also provided, along with a method of determining an environmental condition within which a hardcopy device is operating.

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 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： 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.
摘要翻译：提供推土机型清洁系统，用于从检测与检测器接触的墨滴的静电滴检测传感器中除去墨残留物。刮刀头从传感器上清除墨水残余物，然后接触柔性的，兼容的清洁部件，如螺旋弹簧所示。弹簧在每一端固定，并在刮刀头推动时拉伸。这种拉伸弯曲允许弹簧捕获线圈之间的墨残余物。当刮刀头缩回时，弹簧的收缩弯曲会从线圈之间挤压墨水残余物。当在刮刀的下一个清洁行程期间再次拉伸弹簧时，残留在线圈上的任何墨水残余物干燥，然后从线圈上剥落。还提供了具有这种清洁系统的喷墨打印机构和清洁传感器的方法。
