Abstract: The present invention is directed to a method and system for tracking a photoconductor belt loop in an image forming apparatus that effectively monitors and compensates for changes in the OPC belt's speed and position as well as for possible contamination of the code strip and damage to the photo sensors. There is provided a method and system for sensing a code strip on the photoconductor belt loop with a first sensor, producing a first signal, sensing a code strip on the photoconductor belt loop with a second sensor, producing a second signal, computing a phase shift error between the first and second signals; and synchronizing first and second signals.
