Title: Innovations of James D Buehler
Introduction
James D Buehler is a notable inventor based in Troutdale, OR (US). He has made significant contributions to the field of inkjet printing technology, holding a total of 10 patents. His work has focused on improving the efficiency and functionality of printers, showcasing his innovative spirit and technical expertise.
Latest Patents
Among his latest patents is a method and system for adjusting printhead voltage parameters in an inkjet printer. This invention allows for the mass of the ink drops ejected by the printheads to be maintained in an optimal range without the need for measuring the drop mass directly. After calibrating the printheads, they are operated with electrical signals of varying peak-to-peak voltages. The number of inoperable inkjets for each printhead is determined from image data of the ejected ink, and this information is compared to a predetermined threshold. The peak-to-peak voltage for the electrical signals is then adjusted based on the number of inoperable inkjets and the threshold.
Another significant patent involves an ink consumption determination system for inkjet printers. This system includes an ink feed apparatus with a channel for conducting discrete solid ink sticks. Each ink stick has a sensing feature that triggers a detector as it moves along the feed path. A counter accumulates the number of times the detector is triggered, allowing for accurate tracking of ink consumption.
