    DKS3 1610 for Sale - Complete or as Parts

    How many people are actually running a DKS3 machine? I've not had any interest in mine, so the next step is to strip it down to a collection of spare parts, and put them on ebay. Which parts would be of interest?

    Blue Rubber

    Sadly, I think you are right. I was possibly the last person running a DKS3 in the UK, and not even the service company was interested in my machine for spare parts.
  3. I've decided to sell my DKS3. There is a fault on the tank board, that prevents the racks starting, which I have bypassed with a 12V supply direct to the rack motor and it works enough to produce prints. It would make a good back up or donor machine. It has been stored inside a van, and could be delivered in the UK. I'm based near Bath in England and can demonstrate the machine if you want.. If there is no interest in the complete machine, it will be stripped down for parts and scrap so that I can get the space back. As a complete machine, with some spare parts such as springs and bushes, rack motors, rollers, filters etc I'd be looking for £1000.00 delivered anywhere in England or Wales. For overseas buyers, I could take it to a shipping agent in the UK, but you would need to take all responsibility from there. In both cases, the buyer or the shipping agent would need to have the facility to offload the machine from the van. Any questions, feel free to ask. Cheers Ray

    DKS 1610 Racks not starting up

    I got the DKS to run fine by connecting a 12V supply direct to the rack motor. If you trace back from the rack motor, there is a connector that eventually goes back to the tank board. This can be accessed from the back panel below the drier unit. I connected a 12V supply from an external PC drive to the rack motor connector. The power supply can be turned on or off to start up the racks. In my case, the racks ran a little bit too quick, and to start with I got an error saying the DKS could not achieve the correct rack speed. In the DKS settings, I made a small adjustment to the rack speed, from 180hz to 200hz, and everything works fine. It enabled me to get some more use from the machine, but as I've now gone the dry route, this machine is available for spares or repair, as a unit or willing to break down into parts. I'm based in the UK, and can deliver anywhere in England or Wales. Any offers before I put it on ebay? Cheers Ray

    KIS DKS 18xx series minilabs

    I don't think many DKS4 machines were sold, plus they are much newer than the DKS3 and probably with warranty and service contracts. All of that probably is the reason why there are less posts here about DKS4.

    1610 DKS3 for Spares - what interest?

    Hi David, thanks for the reply. I started a thread in this section of the forum about the racks not starting up. I suspect the tank board is the fault, and would be interested in getting a board level repair done. If that is not an possible at a sensible price, then breaking the machine for spare parts is my second option. The last time a similar fault occurred, it cost me over £4000 with our local service company, and I'm not prepared to spend that sort of money again. Cheers. Ray

    DKS 1610 Racks not starting up

    Hi Ken. Thanks very much for the follow up and the info. I connected a 12V supply direct to the rack motor, and that was good enough to confirm the motor works ok. I tried starting the machine with the racks running, but the software then gave an error that the machine didn't have the right rack speed. I'm assuming therefore it needs some kind of variable voltage supplied from the tank board to get the right rack speed and processing time. My photo shows the tank board as installed on my machine, and as you can see, the cables all seem connected via plugs. I suspect the board is the problem, and it would be great to get a board level repair done as the service agents here charged something like £1400 for a board last time round (and they changed it twice!) I've had great service from this machine, so I've no complaints if this is now terminal, but it seems a shame to lose a great piece of kit for what is probably a simple repair. Luckily I don't have an urgent need for it! Cheers Ray

    1610 DKS3 for Spares - what interest?

    Thanks for the reply Sibi. I have a twin track set for 5 inch paper and a single track set for 8 inch paper. My aim at the moment is to get the machine working again, but if that is not viable, breaking it for parts is a definite option. Where are you based?
  9. Hi, I'm considering breaking my DKS 1610 for spares if there is enough interest. Who is interested in what? I'm based in England, so shipping will be an issue for overseas interest. Could be sold complete and delivered in Europe if the price is right. Happy to discuss all options. Cheers Ray

    DKS 1610 Racks not starting up

    I've put a 12V supply direct to the rack motor and that runs fine, so it looks like the tank board is probably at fault. The two red LEDs in my original post that are flashing are circled on the attached photo. I can't see any obvious candidates to connect power to this board Ken. I'm reluctant to get the UK service company out, because in 2013 they changed two tank boards plus labour charges when the fault turned out to be the rack motor connector. The final bill was over £4000 to change a £1 connector! Ouch!

    DKS 1610 Racks not starting up

    Thank you for that Ken. Appreciate you taking the time to reply. I've put a voltmeter on the plug that goes to the rack motor, and it shows zero volts. I've tried turning racks on from SuperUser and if I click on that, it goes off immediately without the racks moving. I'll have a look at your suggestion now and see what happens. I'm about to pull an old pc apart to get a 12V supply working. Thanks Ray

    DKS 1610 Racks not starting up

    Hi Guys. I've had my DKS1610 from new, and it has developed a fault. It fails to start the racks when booting up. I've removed the rear panels to check basic things like wiring to the rack motoro etc but cannot find anything broken. On the tank board there are two red LEDs in the centre of the tank board flashing. They are marked LD1 and LD20, and run a sequence of LD1 then LD20 then both together. Is this indicative of the fault? All the other LEDs appear to be constant and all are on. I've read that sometime there is a power failure to the rack motor. I've got a spare PC power supply, but can someone give me a guide about how to connect the power supply to the rack motor? Appreciate any help. Thanks Ray, BATH, UK
  13. No problem. Lets see if I can summarise better my above three posts: Go into super user, paper and cassettes. You will see two sections, one for cassettes, one for papers. The papers settings covers the range of widths, surface finishes, and response curves for each paper. You only need to worry about the papers and sizes you use. Your machine has been using 4" and 6" papers, so these should be set correctly already, but you need to make sure the 5" paper is also set the same. Once you´ve set or confirmed the settings for 5" paper you then need to change the cassette settings so that the DKS knows the paper is now 5" not 4" Look in the cassettes section. You will have one cassette ID that corresponds to 6" paper. Take that as your base reference, checking what paper surface and response curve are set. Assuming you use the same paper surface, manufacturer etc, then your settings for 5" paper should be set the same. You will have another cassette ID that corresponds to 4" paper. Make a note of that cassette ID. Go to the paper settings section, and check what is already set for 6" paper (Gloss or Lustre as appropriate). Have a look at the 4" paper settings, and it should have been the same! Now go to the 5" settings, and make sure the settings there are the same as for your 6" paper, ie any response curve etc are the same. Go back to the cassette settings, and select the cassette ID that had the 4" paper. Change the paper to 5" (gloss or lustre as appropriate). At this stage, set both lateral offsets to zero as you need to work from a base setting to start with, and save. Quit super user. You should now be able to print to 5" paper, and they should print when the 5" cassette is in the machine. If you need to fine tune the lateral offsets, you can go back to super user and do it through the cassette settings. Hope that helps Ray
  14. Based on your change from 4" to 5" paper, make sure you choose the cassette ID that previously had 4" paper. Change the paper type to 5" for that cassette, setting surface and the response curve as needed. I assume your second twin track cassette has 6" paper. That will have a different cassette ID and will not need any changes made. When you send images to the print queue, if you make sure you send your 5" prints to paper width 5" paper advance 7", they will remain in the queue until you put the 5" cassette into the machine.
  15. A bit more explanation: Each DKS paper cassette has a chip that identifies it (it is those electronic contacts at the front of the cassette). Each cassette has an ID number in the software. The papers in the cassette are identified manually by your settings in super user, papers and cassettes. That is where you set the width and roll length, surface type and response curve for the paper you use in that cassette. If you change paper type, width, roll length etc, for that cassette, then you need to change these settings. Once they are set, you do not need to change them all the time you continue using the same paper. When you change cassettes, the DKS reads only the cassette ID number, and from that, changes the paper parameters automatically, but only based on the settings for that cassette. Remaining paper length etc is just a calculated figure based on usage of that cassette. Cheers Ray
