  1. This may not be the right place to ask, but I know you folks know your stuff We have a few Epson 1430s we use for sublimation. One of the used ones we just got has the paper feed gripper pretty well worn out and slippery enough that it has trouble grabbing the paper. I've cleaned it quite a few times, and have some rubber rejuvinator coming to try to help it along. I also just bought some replacement roller tires: https://www.ebay.com/itm/254161020343 I haven't found anything anywhere that shows how to get the paper feed roller out of the rest of the ASF assembly, so I can rep
  2. Personally, I think I would run the cleaning fluid through it first, then add the UV ink. That's probably what I'll do if I ever get to that point
  3. I don't think it would be possible to over-cure them. As long as you're not putting enough heat down to actually bake it I think the main concern with too much power is just that you have to find a way to keep the LEDs cool. So, you want just enough power to cure it, without making a headache to keep cool. Of course this probably changes with the type of ink, how much ink, substrate, and local weather conditions
  4. Good to know. Now I'm wondering if a lower wattage LED on the left side of the head to do a "pre-cure", then a strip of higher wattage LEDs on the front edge would be enough to work.
  5. Is 1/4" wide and 1/4" thick still too big for the right side? (can you tell I haven't opened one up yet? ) I also thought about a strip under the front edge, but I've read that (depending on your substrate) the ink has to be cured right after it's been printed, otherwise the colors would start to run and bleed into each other. That's why most will only do one way printing, since the LED will only fit on one side. So if there is room on the right for a 1/4" strip, we should be able to print both directions, and cut the printing time in half. I even saw a commercial printer th
  6. At this point I'm kind of planning to make my own that will be much skinnier, and probably have one on each side of the head. The one on the right will obviously have to turn off when it's over the capping station. But, it may have to be water cooled as well, so I'm not sure if I want to take that plunge into complexity yet. I also haven't taken my printers apart yet, so I don't know if I make it skinner if it will actually make it easier to install/use or not.
