Hi DS,
First, your bulk ink has to be at the same level as your ink cartridge. (For an example: I put a book under my bulk ink system)
I have just installed my bulk ink on an Epson 1280 from www.inkjetfly.com and it's working perfectly. (But my only mistake is that I have purchase the dye base ink instead of the pigment one, newbie mistake) - but the system is working great I had a little leaking while installing but after making a head cleaning it was all fine.
I do not know much about fixing the print head but for the bulk ink that will be my advice.
