There are black specks showing up on my prints?
You may simply have dirt in the water, or you may have a buildup of silver sulfide. Fixer that sits unused for long periods can decompose; this is especially true for fixer that has been mixed as a working solution. As a rule if you want to make clean, archival prints, the fresher the chemistry, the better.
There is something floating in my fixer, what is it?
There are several possibilities, including algal growth and decomposition of the fixer, producing silver sulfide or sulfur. Fixer diluted to working concentration keeps less well than concentrate.
How do I dispose of my used fixer?
Used fixer contains silver , whose discharge is usually regulated. It is also very valuable, so don’t just throw it away!
This is particularly relevant for people using “well water” and spaces that use large amounts of fixer like a university. Please contact your local hazardous waste or chemical disposal company for best practices and recommendations for proper disposal. There are systems for the home and darkroom for silver recovery. Please take care of the environment; we would like it to last a bit longer.
There is a white substance accumulating in my fixer?
It may be sulfur, if the fixer is old.
Can I use the record speed fixer for both Films and Prints?
You use the same concentrate, but at different dilutions. Also, film fixer, once used, will contain substances you do not want in your prints.
Edwal makes fine products, but Hypo-Check indicates premature exhaustion with Sprint™ RECORD Speed Fixer. Instead, try our fixer test. Put a piece of undeveloped film in a small beaker of fixer working solution (1:9) and stir. If the film’s emulsion does not clear, that indicates the fixer has worked to capacity, and will no longer be effective in removing silver from the film. A new batch of fixer working solution should be made.
Sprint’s general recommendation for fixing time is a range of 1-3 minutes. Fixing beyond 3 minutes is not recommended. High-speed liquid fixers, such as Sprint RECORD Speed Fixer, will fully fix any standard emulsion within 3 minutes.
The general rule of thumb is to fix for twice the minimum clearing time. Try this simple test. Put a piece of undeveloped film in a small beaker of fixer working solution (1:9). Stir, and note the time needed to clear the film of emulsion. Double the resulting time to establish your base fixing time, i.e. 60 seconds to clear = 2 minutes fixing time.
When the film clearing time has doubled, it is time to replace the fixer.
Some newer tabular-grain films have a different anti-halation backing than traditional emulsions. After normal fixing times, these films may exhibit a colored tinge rather than a neutral tone in the base of the film. This tint does not mean that the film is under fixed. Sprint ARCHIVE Fixer Remover will help remove the coloration. Longer than normal fixing times are not recommended, because they will begin to bleach the image.
Fixing time for fiber and RC (resin-coated) papers are essentially similar, since the emulsion to be fixed is merely sitting on the top of the paper in both cases. However, extending fixing time with fiber prints allows more fixer to soak into the base of the paper. It is good practice to minimize the fixing time with fiber prints. Fiber prints also have an extended washing time compared to RC prints.
With film fixer, it is very common to see some tint from the dyes that are removed from the film, especially from t-max. This coloration is harmless and generally fades away within 24 hours or so. With prints, some papers can also leave some color behind in the tray. If your fixer has become yellow, it has likely been used too much.
This tint could also be carry over from the stop bath tray. If enough prints are placed directly in the fix from the stop bath, without allowing some time for the print to drain first, you can get enough stop bath in the tray to add a tint. It is best to drain prints until the point of separate drops.
Q: I have been told your Speed Fixer is non-hazardous and safe for disposal in my septic system. Is it safe to dump your fixer without using hazardous waste removal?sprintphoto : November 14, 2011 8:14 pm : FAQs, RECORD Speed Fixer
No. Like all other fixers, once used, RECORD Speed Fixer will contain the silver that has been removed from the film or paper that was processed. Residual silver is considered hazardous, and should not be allowed to enter waste treatment systems or ground water. You should check with the appropriate authority in your state to see what the exact requirements are.
There are a number of methods that can be employed to keep the silver out of the waste stream. Generally it’s as simple as collecting the spent fixer in a container and having that hauled off for treatment. The cost will vary depending on the volume. We suggest checking with your state Department of Environmental Management to see what the regulations are in your area, they may be able to recommend specific options for disposal in your area.
