Epson R1900. Red ink is hopelessly clogged after new cartridge and burning through multiple clean cycles. Epson says tough luck, send it in for service which is hundreds of miles away and mucho dollars. Not worth it although the printer is otherwise fine with not that many pages through it. Just let it sit too long I guess. Anyway, anyone use the cleaning cartridges I see advertised? Like this or this $85 is a bit much to spend on this old printer but I would consider it if this worked and I could use it over and over... Anyone try to clean the heads themselves? And I've heard of people soaking the waste ink tray in ammonia and parking the heads overnight. Hate to dump this printer but Epson seems to go with the use it and toss it business model.
