    That's what I thought, & wanted to have Hytec overnite an IH power supply, but their tech said he's seen this scenario hapen & the firmware was the issue. I was going to try that first & then order the IH power supply. If we replace the fuser unit coil, do we have to replace the IH power supply, too? If the fuser temp is at operating temp & modulating correctly, could it still be the coil? How pricey are they & are they difficult to install? We do have a service repair manual on CD. Thanks.

      Well you could always try the firmware 1st as it would be the cheaper option, but given the history of this fault my money ( sorry i mean your money ) would be on the board.

      The coil is located behind the fsr unit and the fsr power supply is below the ops panel and above the main on\off switch, not to bad to fit, but make sure you wire the ac connections correctly.
      The gene pool could use a little chlorine.

        Thanks & found an older post w/ the link to the R5 Firmware upgrade, but its a Canadian version. Is that ok to download for our US C650?

          I don't see why the Canadian version should be any different from the US version.

            I just tried to download the link from an earlier post for the firmware & its only an acrobat file & there's no software link.
