Abstract
A system and method of determining a residual toner mass on a receiving member includes providing one or more test patterns to the receiving member, transferring the test patterns from the receiving member to a transfer medium, determining a sensor signal obtained after transfer, processing the sensor signal obtained after transfer and determining an amount of residual toner mass based on the processed sensor signal. A xerographic marking device also includes a receiving member, an array-type optical sensor or a point optical sensor arranged on the receiving member, and a controller that generates one or more test patterns, transfers the test patterns to a transfer medium, determines a sensor signal obtained after the transfer by the optical sensors, processes the determined sensor signal, and determines an amount of residual toner mass based on the processed sensor signal.
