Abstract:
A photocopy machine and method where working solution flows down from a transfer drum into a trough-type filter and is then filtered as it flows into the main portion of a tank for subsequent recirculation over the transfer drum. The filter trough is preferably formed from a foamed polyurethane plastic and removes undesirable dust particles from the working solution. The filter also collects and filters gelled solution.
