Ok, so now i have this printer firing on all nozzles according to the nozzle test pattern. I filled black with mostly yellow and a small amount of black MISPRO ink mixed in. Even with all nozzles firing according to nozzle test i still see the lines of the nozzles, even on paper. So on a PCB this basically causes lotsa little gaps between the individual lines. After baking the color resists sufficiently, i can get a pcb with many parallel very fine lines. It seems the distance between the lines (or missing lines?) is not the same, when i print a block of color it looks like some lines are simply missing, periodically. How is this possible when according to the nozzle check pattern all nozzles are firing? So what now? Any ideas? Does this mean one needs a printer with higher resolution such as Volkan used? BTW Steve, thanks for your instructions! Your cleaning mix and the method of putting it on the parking station cleaned the two stubborn nozzles right up! So what now? what about the gaps, and what do we do about the puddling? Any ideas? This printer would take small strips of PCBs no problem, no modification needed. I just drop them in on the moving sheet of paper. But the strips must be narrow enough to fit around the bend of the paper feeder (a bit over an inch does still fit fine). Would be easy to cut up for larger PCBs though. ST
