ICPs are small resistors that protect the PWB from overcurrent if the load associated with it has an issue. You can check them by "OHMing". Just like a fuse. Problem is if they are open you have to replace the board anyway. If you have a blown ICP you should replace the componant it protects at the same time, if not, you will probably blow the ICP again. On the C650 series this indicates a problem with the REYB/PH. On the production print MFPs it also indicated a PH problem. Emujo
