when printing im getting a halo of other colour at the side of each digit, not long ago i had a major screw up with the machine we tried bulk ink this leaked from one of the heads onto the board which in turn blew the head board and the main board i replaced the onboard fuse but i had lost group b (yellow and light magenta) we replaced the boards but not the head which then blew the new board, fortunetly i managed to get a circuit diagram for the head board from Roland in Japan (they also had encounted problems with problem boards blowing i replaced 2 ic's and a mosfet believe it or not it worked i also replaced the head which had caused all the issues, my problem is that the 2 heads yellow and light magenta now appear to be printing slightly outside of the printable area hench the halo, i've adjusted the bidirection print set up but i know need to manually adjust the head i was hoping in the manual it would give more indepth detail on how to do this? hope you haven't fallen asleep whilst reading this many thanks for any help john
