I was recently asked to help out a fellow technician that replaced both a motherboard and hdd on a E22B at the same time. He has since put the original motherboard back in and is using the new hdd and also changed the video board. It looked like the video and hdd board fixed his original problem. The problem is that the E22B will load and is accessible from the copier's control panel but it won't print a thing, not even a configuration page. All patches and updates have been installed. The security or keychip was transferred from the motherboard to the new motherboard and then back again to the original motherboard. Is this a situation in which the license for the print server itself needs to be reloaded? Does anyone have the procedure to do that?
