RIPC is the Roland Intelligent Pass Control, where the machine lays down LC and LM in both directions to help with the inherent banding created by bidirectional printing. I guess it wouldn't be available on the SP as it's a 4 color machine, but I thought it was..
You should be able to print using the PCV2 profile on standard and get about 100sf per hour. I believe that is 8 pass.
