Having a problem with a c280 dont know much about these models. The machine has print fax and scan. I must take out hd but when i did the machine would not boot up, so i was able to get in and turn hd off and but coded fax prob. So i pulled fax out and turned off machine and fax. But machine still freezing. I try trouble reset, nothing.... Any ideas on fixing the problem.. I also tried putting everything back in but i cant do anything it just keeps freezing.
