ABSTRACT:
In an automatic film developer, measurements are taken of internal temperature parameters during a warm up phase. Based on measured temperature values a time for completing the warm up phase is calculated. The calculated time for warm up is displayed so that it can be read by an operator. When the calculated time for warm up completion has elapsed, an indication is displayed that the film developer is operational. During the warm up phase, film is not allowed to advance through the automatic film developer. When the calculated time for warm up completion has elapsed, advance of film through the film developer is automatically started.
