  1. OK, now you are into an area I know. Kodak C41RA fixer has a definite propensity to crystalise on the squeegee rollers (the last 2 rollers in the rack) as the film goes into the crossover, and into the next tank. The official Kodak directive was to increase the rep rate by 10%, and add an extra litre of water to the fixer mix. (5L of concentrate with 6L of water) We have run that way for 10+ years with no issues. I'm not saying that is your problem, but it is something to consider. As to why only 2 film types are affected - that is odd. A wet swollen emulsion going through a rack should not be any different for different brands and I wonder if this is coincidental? Try swapping your 2 fixer racks around, and see if it makes a difference, and even swap rinse racks around (but NOT the final rack). I know how hard it can be to isolate these problems, and you just need to keep trying different ideas to see if you resolve it.
  2. What chemistry are you running? Kodak SM or Fuji. I know the SM fixer used to have some issues with crystalising on the the top rollers, which sometimes marked films. Does it happen on every film or only intermittently? If it is on every film, then run a brand new, uexposed film though the machine and pull it out as it leaves rack 1. If no marks on it, run a brand new film through racks 1 and 2, then pull it out and check for marks. If no marks, run through racks 1,2 and 3 and check again. This might help you to isolate where it is happening, but only if the marks are consistent. to get the film out of the rack as it transports through, remove the crossover and just lift the leader card out, with the film on it - don't tug on it, just keep a firm tension on it for the film to exit the rack. Let us know how you go. Alan
  3. Thanks to Yustas for his help. It's nice to know we are such a helpful community to each other.
  4. Does anyone have a scanned copy of the parts manual for the Noritsu 430L3? Mine seems to have gone missing.
  5. We always do them as negatives and then batch invert in photoshop.
  6. Have you run a control strip to check your chemistry? It is pointless trying to make corrections in your printer if you chemistry is out of balance. It may be incorrectly mixed, not replenishing correctly, or contaminated. Have you checked the replenishment rates on your pumps and calibrated them? Forget playing with the printer until you know your chemistry is OK. Fuji and Kodak both have RA4 process control strips, and even if you do not have a densitometer, a visual comparison of a strip from your machine, and the reference strip will help to rule out a chemistry problem.
  7. There are things out there called control strips - these tell you what your chemistry is doing. To run a lab requires investment - investment in control strips and a densitometer. Sorry to be so blunt, a control strip would have told you what you need to know in under 10 mins.
  8. We have the latest version of Ezcontroller (2 licences/2 dongles) running on 2 separate Win10pro computers with no issues at all
  9. This may not answer your question, but EVERY Noritsu lab owner should have a spare AOM sitting in the spares box. They are so easy to change over, and so easy to see if it has fixed the problem.
  10. We have just installed a 3901G, upgraded our S4 to an HS1800 and are getting an S600 scanner soon. we are still sorting through all the paper work and discs.
  11. Ours will be standard RA process, just like our existing 3202.
  12. We have just ordered a new 3901G as well as an additional film scanner (LS600). We will be running an LS600 on the new lab, and the HS1800 will be on a separate computer running the latest EzyController, being supplied by Noritsu. My reason for putting the LS600 direct to the 3901 is that 70% of our work is 35mm scanning and printing, and slides and 120 are more time consuming and not usually time dependent. My plan is to have 2 staff working on the lab - 1 of them scanning 35mm and printing digital files, and the other doing 120 and slides on the HS1800 with Ezycontroller. Can anyone give me an idea of how the 2 will work? We won't have the new lab for about 4 weeks, but I'm trying to get my mind around workflow. I'm guessing that the HS1800/Ezycontroller will put the files into a hotfolder which can then be printed later - or am I not understanding how it all works? Any info would be gratefully received
  13. They still have to make it, so it will be a little while yet - pretty excited about it.
  14. Don't know if you have the info now, but it is here. http://www.noritsu.com.au/qss3901g.html We have just ordered one to replace our 3202.
