I have a Thermaphot ACP 302 print processor which I used the other day to print my postcards for the postcard exchange. I currently only have time to print once a week so I was thinking that I could just leave the chemicals in the machine until the next session for convenience.
But is this a bad idea? I'm thinking that it might be harmful to the machine, and/ or that the chemicals will go off. Perhaps it would be best to drain and clean the machine after each session? How long can I expect the chemicals to keep if stored in 2.5 l plastic containers. Btw. this is B/W.
