Other than networking/connectivity issues, Pinnacle refers all printer / copy machine services to either the vendor who sold you the machine in the first place (for leased large multifunction machines), or Matt Burrell with D&B Copy Systems for the smaller desktop-style machines.
Matt can be reached at:

Matt services and sells off-lease large multifunction machines, and stocks a wide variety of high-quality after-market toner as well (including personal delivery!)
