I am looking for a Roland FJ 50 Service Manual. I have the user guides but was looking for the good stuff. Please let me know if you have it. I have a FJ 50 I am trying to determine if the printer is worth investing in. I have a print head that smokes when I power the unit on. What I believe I should be able to do is enter service mode with the heads disconnected and run through the system with the heads disconnected. If the system seems functional and I really have a bad head I can then proceed to get the heads, capping station, pump, dampers, new ink lines, wipers, and ink and may have a slow but good resorce. When I power the unit on with no heads the message on the unit display tells me low temperature so I am thinking the unit may be worth looking at. Any help is much appreciated.
