I bought a virtually new CPA-2 processor. It' is the latest version with the upgrades. (It's serial number is above 23,000.) The original owner bought it but never used it. While getting familiar with its operation before processing my first batch of E6 film, I noticed that drum rotation speed doesn't increase at any setting over "3." Today I tested it using a small single-roll 35mm drum and also with an empty Expert 3010 drum and then with 500ml of water in the 3010 drum. The tempering bath was filled to the proper level. I set the processor to run continuously in one direction for the test. Suprisingly, there was very little difference in the speeds when using the 35mm drum and the filled 3010 Expert. Even more suprising, if anything, the 3010 when filled actually rotated slightly faster than the 35mm drum! Here are roughly the speeds I get: F - 35 rpm 3 - 66 4 - 72 P - 72 6 - 72 7 - 72 There were some variations but those numbers are pretty accurate. Again, the rotation was actually FASTER with the filled 3010 drum. Maybe the machine was just warmed up or something. But the point is that I'm not getting any speed increase above the "3" setting. Has anyone else experienced this? If so, did it turn out that the Rotation Speed control needed to be replaced? Lastly, I removed the four screws on the control panel hoping to be able to lift it off and see if there might be a loose connection to the speed control but the panel didn't want to come off. Maybe it just needs a little force to crack a seal (?). Has anyone removed that panel and, if so, how?
