ABSTRACT:
The feed of a continuous strip of light-sensitive paper to a high speed printer, of known construction and operating mode, is made from a large-sized spool, independently supported in a dark room and fed through a tunnel-like enclosure to the printer, thus obviating the current practice of having to replace this component, now typically consumed approximately every ten minutes of operation and usually requiring a ten minute down-time period to effectuate the replacement, at such frequency as to almost neutralize the advantage of the high speed of operation of the printer.
