I got a 16x20 zone 6 archival washer last year and was very annoyed that it didn't have a drain plug. But now it has become a big improvement in my system. I sometimes print fiber all day long and I will rinse the prints in a tray for a short while then put them directly into the washer where they accumulate. A few times a day I will turn the water on enough to completely exchange the water in the tank and then turn the water off and let them sit. At the end of the printing session I will refreshen the water again and then a couple more times in the evening and several hours later I will take them out. One thing is that usually my fiber prints float and as I understand it the hypo is heavier and sinks. As there is quite a volume of water below the level of the prints I think the prints must be sitting in relatively clean water many hours with out near the volume of continually running water. |
