Hello, I’m new here so apologies if this has been answered before. I have a LM-8E manual lensometer and have just refilled the ink cartridges. Now it seems the little tip that comes out the very end is only out on one of them so it’s not giving me 3 dots, only 1. I have taken them apart and reassembled them again and again but I don’t know how to get them back the way they were. Does anyone have any experience with this? I have reached out to Topcon but all they are saying is that I can buy new cartridges for $300. There’s got to be a better way… thank you!!
