littlephoto Posted March 30, 2012 Report Share Posted March 30, 2012 Hello, I'm wondering if anyone has any ideas on this problem we're having. We have a Fuji Minilab FP232B and for a while we've been having heater abnormal warnings. Right now N1, N2, N3, NS1, NS2, and N4 don't seem to be heating well. I opened the side and Heater 1 is heating and warm to the touch but the other two are still cold. I know that we'd tried replacing Heater 2 months ago when we starting having issues but the Christmas rush side-tracked us. We also had cleaned and inspected the tanks and lines but didn't notice any issues there. We were told about little circuit protectors on the main board we can push that might have been tripped but that didn't seem to fix anything either. Any ideas on what we could do to fix this? We don't do alot of film but still like to provide this service for people in the area. Quote Link to comment Share on other sites More sharing options...
manager Posted March 30, 2012 Report Share Posted March 30, 2012 heaters don't die just that easy. the problem is for sure the relays that turn heaters on or off. I don't remember their names, drivers or something. A simple electronic component that cuts or opens power to heaters. Quote Link to comment Share on other sites More sharing options...
littlephoto Posted April 7, 2012 Author Report Share Posted April 7, 2012 Thats what I had wondered originally because when it's warming up in the morning before we start it up, you can hear a relay ticking away every few seconds. Quote Link to comment Share on other sites More sharing options...
manager Posted April 9, 2012 Report Share Posted April 9, 2012 SSR relay, I think its the name of the part Quote Link to comment Share on other sites More sharing options...
littlephoto Posted June 19, 2012 Author Report Share Posted June 19, 2012 Yes, this seemed to be the problem. I took the board off, replaced 2 relays on the board that were giving me trouble and voila! It heats up quicker than I've seen it do in 4 years. Thanks for the help!

littlephoto Posted June 21, 2012 Author Report Share Posted June 21, 2012 Well the heaters seem to be working now. The problem is that the last tank (n4 rinse) heated up to 36 degrees then stopped. All the other tanks are at the right temperature. Any ideas on what would cause this one tank to stop that close to it's proper temperature? It's been mentioned there might be some kind of airlock because it doesn't appear to have good circulation in the tank, but I had cleaned and rinsed the tank out with water.

littlephoto Posted June 23, 2012 Author Report Share Posted June 23, 2012 Not sure why but it seems to be heating fine now. I guess it just needed a break to get back in the groove. Unfortunately the problem now is that on the emulsion side of the negatives I'm getting a uniform line pattern that runs vertically across the negatives and can be seen in prints. It doesn't come off like any kind of gunk build up. Could it be something on the rollers though? Quote Link to comment Share on other sites More sharing options...
nash Posted June 25, 2012 Report Share Posted June 25, 2012 if its like a dark banding across the negatives. This could be a circulation problem Quote Link to comment Share on other sites More sharing options...
littlephoto Posted June 25, 2012 Author Report Share Posted June 25, 2012 I dismantled the N4 rack and scrubbed it down. I noticed the solution was brown and had stained and built up on the walls of the tank. Took the filter out, disconnected the lines and cleaned everything, then flushed. I must have collected a pound of sediment. The line from the filter side was just plugged up, and so was the drain valve. Running water through it now to try and clean as much gunk out as I can before I refill the solution. Quote Link to comment Share on other sites More sharing options...
