Abstract: An answer document or form, on which the user darkens certain discrete response areas with a graphite or lead pencil to denote his selected choices or data entries, has a bias bar printed across one end with the same color ink used in printing the remainder of the document. When the document is read by the optical scanner, the light passing through the translucent paper also passes through the printed bias bar. Analog voltage signals are obtained from each of the photocells in the optical scanner and these signals are capacitively stored, then converted to digital values. The digital values are averaged and the individual digital values for each photocell are compared with the computed average to check for bad cells. If a poor photocell response persists for a predetermined number of answer documents, the entire scanning operation is stopped.
