This is my dads printer and I bought him hobbicolor inks from ebay and hes been refilling using the german method for about 6 months. There has never been any maintenance done on the printer and I knew sooner or later there would be some issues. I have been reading for days and realize that the head may be clogged etc but Im not sure where to start. Theres also terminology that im not 100% clear on. The head is the black piece that the cartridges go into? that you can remove by lifting the gray bar? I have found zero writeups with pictures so thats why im posting. (sorry i hate cluttering forums) Im going to post some pictures.... well im not allowed....
