Latest Patents

Ramkumar holds a patent for "Printhead nucleation detection using thermal response." This invention provides a method for determining the pulse width for driving printhead nozzles in a thermal inkjet printer. The process involves preheating the printhead to a desired temperature during maintenance mode. The nozzle heaters are then driven in successive heating intervals, characterized by shorter drive pulse width pulses occurring at a higher pulse frequency. The temperature data received during each interval is processed to determine a respective temperature slope. By comparing these slopes to a desired threshold, the pulse width associated with the matched slope is utilized for subsequent printing operations.
