Ok, so here's a quick back story. Bought a Brother GT-381 at an auction, the company was seized by the bank and the doors were locked, equipment sat idle for months. Picked up the machine for a fair price. Now trying to get it cleaned up and running. It was not well maintained when it was running. Needles were clogged and one ink line took some real effort to clean. Drain side has some issues that I haven't dove into yet. I've got 2 of the 4 white heads close to clean the other 2 are allowing solution around the stainless steel insert where the ink ports are located. I know this isn't right. What am I going to find if I disassemble the head itself...has anyone ever gone there?
