In designing software for the belt-type document handler portion of an electro-static-type copying machine, there are many functions which have to be performed after waiting for the document handler belt to travel a certain number of inches. For this purpose, reference holes are provided in the belt at every inch in order to enable the software to keep track of the position of the belt. Also, a sensor is provided to sense longer pitch or track marks on the document handler belt.
