Greetings All
I Found a used Zone VI Washer 11x14 at a local camera store. In pretty good shape at a good price. Seems to work fine but what's the purpose of the two spare acrylic sheets that came with it ?? They're about 17" X 4 1/2" but don't seem to fit anywhere in the washer unless I remove some print dividers. Any brilliant ideas ?? Thanks All..Jef |

Thanks All..Jef IIRC, they were so you could remove all the dividers, and you put those things in. Then you could put one of their negative washer baskets in there with the sheet film in the basket for washing sheet film. I never bought the basket or thought of washing negatives in there. For paper, the slow water flow rate is appropriate, but I prefer a much faster water flow rate for washing negatives. IIRC, Kodak recommend 6 changes an hour, but I may be mistaken. I generally wash the negatives in the developping tank and have about one change per minute for 10 minutes. I fill the tank with the negatives in there, jiggle the reels a little and dump it. Then I let it refill and wash 5 minutes. Then I dump it, let it refill, and wash another 5 minutes. This after one minute in KHCA, or course. -- .~.

Yes the short sheets are intended to support the sheet film washer (submerged) or for stacking roll film reels. To use them you remove as many standard dividers as is necessary. The Zone VI catalog says: "With dividers removed, any of our print washers can be used for archival washing of film on reels". I usually stack reels, up to (3) deep, on the inserted short sheets. About 15-18 reels can be accommodated this way. I've used it since'82 and it works fine. Doug |

Thanks All..Jef I'm pretty sure one is used to lay on top of the vertical pieces when it is full of prints and washing. The print edges have a tendency to rise a little bit out of the water, and thats what it is used for....to "hold them down". At least I have 2 similar things for my 16x20 and 20x24 ZoneVI washers. No. It is true that such a thing is supplied with new washers, but I believe the O.P. is talking about the thing you get a pair of with each washer. I do not believe I have ever unwrapped them. -- .~.

Thanks All..Jef Don't these replace a pair of dividers so that you can drape a 16X20 across multiple slots ? Regards, John S.

![]() wrote in message ... Does anyone know how to control the overflow? When the water reaches the top it pours over onto the floor. I hope someone wil reply. thanks, Victoria I have a large Zone VI washer although I haven't used it for a while. I always put mine in the bathtub. The only way I found to prevent overflow is to adjust the filling rate to it doesn't. In fact, from experiments I made long ago with dye to determine the time it took the water to change I mostly ran it to deliberately overflow. These washers work OK but are not wonderful. For single prints I mostly use a tray with a Kodak Print Siphon in it. This works quite well for single prints or perhaps a tray with a number of small prints that can move around freely, but is not so good for a stack of larger prints. There is probably an ideal print washer but I've never seen one. -- -- Richard Knoppow Los Angeles WB6KBL |

I hope someone wil reply. thanks, Victoria I have a Zone VI print washer, 11"x14" size (i.e., it will wash prints that size or a little larger, but not 16"x20". The way I run it, tempered water flows in the hose connection at my upper right into a plenum chamber. While in there, some of the dissolved air comes out of solution. I wish it all did. From the plenum, the water enters the main chamber through to rows of small holes; one row near the top (but below the water level) and another row near the bottom. After the water has washed the prints, it exits the washing chamber through holes at the bottom into the exit plenum. Picker did that because he believed hypo is heavier than water and it would sink to the bottom. That happens to be nonsense, but it does not really matter. The water rises up in the exit plenum and goes out the overflow pipe. _There is no reason whatever for the washer to overflow_. The exit pipe is about one inch in diameter and the intake pipe is effectively about 3/8 inch. There is little point running much over 1/2 gallon per minute through that, since washing is a diffusion limited process. But even if you run a gallon a minute, it should never overflow. What flow rate could you be running that the water comes into the tank faster than can escape from the large drain pipe? I have never had it come anywhere near the top. The biggest problem I have with the washer is that not all the air comes out of the water in wintertime in the entry plenum chamber, so some of it comes out on the prints. I wrote to Fred Picker about that and he said it was not a problem because the bubbles grow in size and float off the prints and they do not impede washing. Well, I have studied them and they can remain firmly in place for over 15 minutes, and they do impede washing. So every 5 or 10 minutes I quickly raise each print and briskly reinsert it to get the bubbles off. They are caused by mixing the cold winter water with the hot water to get wash water the right temperature. I tend to do my B&W processing at 75F because I cannot reliably get it colder than that in the summertime, and I prefer to use the same temperatures all year long. -- .~.

Mine is the 16x20 washer. Very heavy. I tested it using
beet juice to see how long it took for the red color to clear. At normal flow rates, that is, no overflow, it took too long so when I was using it regularly I put in the bathtub and let it overflow. -- -- Richard Knoppow Los Angeles WB6KBL "Jean-David Beyer" wrote in message ...
