Patent ID: 7983579

Claim:
A system for providing detection and adjustment of toner transfer performance, comprising: a light-transmissive transfer belt for receiving an amount of toner mass; a transmission sensor for sensing light transmission through the light-transmissive transfer belt, the sensor comprising: a light source positioned over the light-transmissive transfer belt for applying light to a position on a surface of the light-transmissive transfer belt where the amount of toner mass is to be transferred, and a receiver positioned on a side of the light-transmissive transfer belt opposite from the light source for receiving and measuring an amount of light that passes through the light-transmissive transfer belt; and a measurement and control circuit connected to the transmission sensor for computing a difference in light transmission with and without an amount of toner mass on the surface of the light-transmissive transfer belt, wherein the difference in light transmission is used to calculate a transfer parameter that can be used to adjust toner transfer performance.
