ABSTRACT:
Pressurized air and vacuum levels are controlled to facilitate sheet separation and feeding reliability based on the weight of a document sheet stack on the document sheet stack support. The weight of the stack is determined by counting the total number of individual document sheets in such document sheet stack, determining the height of the original topmost document sheet of such stack at a particular point in time, counting the number of individual document sheets fed from such stack from such particular point in time, computing the weight of each individual document sheet based on the counted number of document sheets from such particular point in time, and calculating the total weight of such stack based on the weight of each individual document sheet and the total number of document sheets in the such stack.
