I got a Jobo CPA 2 roller processor from a guy on Craigslist who had looted it from a newspaper some years back. I was doing C-41 in a rubbermaid container with fish tank heaters before, so the automation and fine-grained controls of the Jobo are a welcome improvement.
After one day, and one roll, the pump stopped working. I was dismayed, but it turns out it’s really easy to open.
It has a nice big heater, and a spinning water pump mounted to the bottom of the control unit.
It turns out the pump was blocked by a hardened, crusty bit of old chemical goo. Scraping that out got the pump moving again.
It’s all running again, and boy is it nice. I can actually walk away for a few minutes. I don’t have the ‘lift’ version, though, so I still need to be there for chemical changes.
