Abstract

In failure diagnosis of nonimpact printers, such as ink jet printers, is often helpful if the ink pressure in the nozzle is known as a function of time. In IBM Technical Disclosure Bulletin 21, 4925-4927 (May 1979), there is disclosed an ink jet nozzle pressure measurement system to achieve such a function. The circuit presented in the drawing is a simplification of the system illustrated in the aforementioned reference.
