what is Durst Printo system for?

  1. I finally opened the boxes today!

    One Energy, two Intro's, one Tank (in a wrong box).

    The Intro's have manuals and sealed plastic bags with a few red gears and a metal plate). The power cords have broken rubber bands, but one cord holds its folded shape. I suspect they never got used.

    The Tank module in an Intro box had a mouse nest and some gnawing on the clear rubber tube which is taped in place. Broken rubber band with that cord also. No manual, but other than the evidence of former rodent residence, it looks clean (as in no chemical stains/residue). There is a single red gear in a sealed plastic bag with that module.

    The Energy module just has some dust on the box. If the heating elements show signs of 'cooking' with use, I'd assume little if any usage. At the top of the element there is some orange/yellow material that looks more like electrical insulating varnish to me than residue...or I'm wrong.

    Anyway, the point of this update is that I would like to inquire which rollers are notorious for sticking together. The Intro modules seem to have free-rolling light grey rollers. The Tank module has harder light grey rollers and softer black rollers. The gearing is pretty high (as far as my fingers are concerned) so I cannot tell whether the gears should make the 'helix' rotate continuously in the same direction, or if it oscillates back & forth over a range of motion. It rolls so far and seems to want to stop (again, based on resistance to finger rotation). If the rollers were stuck together, I would think I could not achieve a portion of a rotation of the rollers, or the soft material would pull off as some describe on the 'web.

    I would like to learn how to assess the condition of the rollers or any other 'weak link' areas...to determine if these are in questionable or pristine condition. I do not anticipate using them but prefer to identify the physical condition as accurately as possible if I offer them for sale somewhere/somehow. I would rather honestly identify any problems than use the 'I don't know anything about this' excuse.

    I'm on a roll now...it won't be another 11 months for my response!

    Thank you

  2. Unless you are going to be printing on a daily basis, the rollers should last you quite a while. You just have to remember to clean them thoroughly after each use, or they will start sticking together. Once that happens, there is a chance that chunks of the roller material might start tearing apart during operation. Depending on the tears, this would render the rollers and the machine inoperable. This has not happened to me (so far), but my guess is that other than paper jams, the processing liquid would not pass smoothly over the paper creating gaps in your processed images.

    The red gear is probably a replacement, or it could also be a gear to change the speed of the processor to allow for different processes such as B&W, or E6. I'm not sure ?

    Tell you the truth, I'm not sure what tube you are talking about that is taped to the Intro Module ? My Intro-module contains no tube since its only meant to introduce DRY paper into the other "Energy" modules (Developer, Stop, Fix). My other modules do have a tube attached to them which is meant to easily drain the liquid after use.

    I'm not sure what that orange/yellow material that looks like insulating varnish is ? None of my Thermo-Pots have them and I have 4 of them ! It could be somebody operated the Energy/Thermo-Pots without any liquid and they show signs of burning . Hope I'm wrong !!

    I'm pretty paranoid about my rollers(due to the fact that you can't get replacements anymore), so after each use, I wash them with plain dish washing cleaner and running water. I guess there are better cleaners than that out there, but I want to avoid any harsh chemicals that might aggravate the situation. Some people place a small piece of paper, or cardboard between the rollers to keep them apart during storage and/or between runs. I have not found this necessary yet.

    Occasionally, I do run plain clean water through the modules for an about an hour or two, just to remove any lingering residue. The rollers you really have to worry about are the ones that actually squeeze the chemicals from the paper while the processor is in motion. I think those are lighter in color and seem to be made from another(softer) material than the black guide rollers, but I would think the guide-rollers are secondarily as important.

    One of the biggest problems you might run into, is trying to get 2 or more modules together. I would start by trying to attach the Intro module to a single Energy Module with Thermo-pot. Then turn ON the switch, but please don't let the processor run like that without any liquids for too long, or you might cause irreversible damage to the unit.

    Once you have that going, try to attach a second Energy module to the first one, then a third Energy module to the second etc, making sure that all modules are in sync and working together in unison. This may sound easy, but due to the plastic on the Energy modules warping due to heat or old age, they might not fit exactly right. **The modules have to fit exactly right in order for the processing to work seamlessly without any paper jams, or other issues.

    Also just like darkroom trays, I would recommend marking each module (Developer, Stop, Fixer, Bath) and using each module for that sole purpose. This will avoid contamination issues which can be very hard to detect.

    Once everything is working as it should, then you can basically relax and not have to worry except for putting paper into the machine. This is an extremely quiet and smooth processor which makes it a joy to use ! The worst thing you can do however, is to let it sit there for days with processing liquids still inside. Most of us hate clean up, but with this processor, given that there are not many parts available, clean up is a must.

  3. Indeed! Cleaning the rollers after use is essential. Since any chemicals allowed to dry on them will stick the rollers together, and possibly eat into the rubber (neoprene?) if left for a length of time.

    Any rubber tubing is for drainage of the chemicals after use. However this assumes you can elevate the processor in some convenient manner. You might want to get hold of a cheap plastic-bodied 'water feature' or aquarium pump and use that for emptying the tanks instead.
  4. When I still had a darkroom, I used to do this sort of thing. No More.

    Photoshop and a good printer are so much easier, tho' the topic does bring back a sort of photo-nostalgia.
