Abstract: A photo film processor has a bath component, which contains processing liquid and processes photo film by use of the processing liquid. A processor body contains the bath component. A replenisher supply device has two cartridge holders loadable with two replenisher cartridges, which contain replenisher liquid for adjustment of the processing liquid. Two tanks store the replenisher liquid having flowed out of the replenisher cartridges. A maintenance opening is formed in the processor body. A panel is secured to the maintenance opening movably between closed and open positions. On the panel, the cartridge holders and the tanks are mounted. The panel, when in the closed position, closes the maintenance opening, and when in the open position, is positioned outside the maintenance opening, for allowing inspection and/or maintenance of the bath component.
