Due to all the research and development we do, we have a LOT of printers. There are some we use constantly for production printing, some main ones we use for testing, and a few that were used for tests over the years, but now mainly sit unused. Our 3800 is several years old, and has worked like a champ- first with the continuous ink system we had about five years ago, then the 120ml refillable carts, and most recently the current 80ml refillable carts. We have used it with Epson, ConeColor, Piezography and InkThrift inks over the years, and have had excellent results until sometime last year when the magenta channel started having flow issues. At the time, we got a new 3880 printer to test that model, and didn’t have much need for the 3800- so I installed a set of PiezoFlush carts and it’s been sitting for the past year waiting for me to have time to work on it…
Yesterday, after I have been working on some of our other printers recently, and have a few customers out there struggling with 3800/3880 clogging- I decided it was time to work on the 3800 and see if I could get it working again. We have a bag of individual dampers, though there are no instructions for replacing just the dampers, and everything I have read directed me to replace the entire ink system (which is why we don’t have these model dampers on-line for sale)… but I was curious if I could flush the print head and replace the individual dampers to see how the printer worked, before buying any more parts.
Since I didn’t have instructions to follow, and wasn’t even sure if it was possible, it was a bit tricky this first time- but now that I’ve figured it out and had success, I can write instructions and help our customers do this repair to their own printers.
Please let me know who’s interested in learning what I did, and would like to replace dampers and flush the print head try fixing their printers. It will take me some time to put my photos together and write instructions, and I’m always very busy- but if there’s enough demand, I will make the instructions and order more of these dampers to have available for you!
Best regards and happy printing~ Dana
