Abstract
A facsimile recorder for marking an electrosensitive web with a remote scanner signal including a periodically interrupted framing signal and a video signal comprises a scanning electrode and a cooperative electrode for marking the signals on the web during successive scans across the web. Scanning of the web is controlled by a framing circuit which compares the remote scanner framing signal with a recorder generated signal and uses the asynchronism of the two signals to control the scanning electrode until it frames the recorded scanner signal on the web. The recorder pulse generator comprises means sensing the voltage impressed through the web by the scanner signal. When the scan completes its crossing of the web the voltage drop across the scanning electrodes increases producing a recorder pulse which is delayed and applied to the framing circuit.
