Abstract:
An image forming apparatus which provides transfer belt position correction, said image forming apparatus comprising:a removable transfer belt subassembly containing a transfer belt for receiving an image thereon;a home position indicator associated with said transfer belt;a non-volatile memory storage device having calibration data stored thereon regarding said transfer belt, said calibration data being associated with said home position indicator, said memory storage device being mounted on said transfer belt subassembly;at least one sensor for sensing said home position indicator; anda controller that utilizes said stored calibration data and signals from said at least one sensor to control positioning of said transfer belt such that, upon installation of said transfer belt subassembly into said image forming apparatus, said controller relies on said calibration data to effectively correct errors in the positioning of said transfer belt without undergoing any belt calibration cycle to generate a test pattern.
