ABSTRACT:
An electrostatic reproduction machine having an improved control circuit to control turn on of a discharge lamp positioned to discharge a moving photoconductive belt member prior to development thereof. The control circuit enables a first mode of operation for copying standard length documents of 81/2 inches in length and a second mode of operation for copying documents greater in length than 81/2 inches without erasing image areas by the discharge lamp. For the second mode of operation an RC adjustable circuit enables a suitable delay before lamp turn on. A machine operator can easily select the desired mode of operation.
