I never dry drums when I work with color papers at Jobo processor. For quicker work I use this sequence: 1´ prewash, 1´developer, 30"stop (2% acetic acid), 30" wash. Now I get out prints from drum and put them into blix, which is in the larger tray. Now I put the new papers into drum and all repeats. When the next ones are developed, I get out prints from blix, put them into tray with water and after session I wash them with running water.
I'm afraid that a wet drum from such a process can lead to spots on prints and also colored contaminations.
