I have been happy with tray washing the last 11 years. 1 min in an alkaline fix (TF-4), 5 min rinse, tone as required, 5 min rinse, 10 min in a wash aid, 20 to 30 min tray wash with 6 fill and dumps. Tray capacity is 4 or 5 5x7s, 2 or 3 8x10s, 1 or 2 11x14s. Advantage, low cost, small storage footprint, no fuss with heavy tank. This works great if your DR production is low for each session. Before washing I trash prints which do not meet my standard. Reduces print volume for the wash step.
