HP 7612 Wide Format Printer Problem

[jwnr]

My HP 7612 Wide Format printer is amazing except that the magenta print head does not print fully.  It leaves spaces when printing.  I have done all of the cleaning,  aligning and maintenance on it several times and all the others work perfectly except for the magenta.   I have replaced the magenta cartridge several times and still get the same results.     Is there anything else I can do to get that one print head to print correctly?
