Here are some things to try first before you buy a replacement Fiery: If the fault code comes up after a short time or is coming up intermittently, then the problem might be a bad CPU cooling fan assembly (see if the fan is blowing well or not). It could also be poor connectivity between the CPU and its socket on the motherboard.
Open the thing up (powered down and unplugged). Use good ESD (ElectroStatic Discharge) procedures to avoid shocking the electronic components with static from your touch (use a static eliminating wrist-strap, or if not available, ground yourself by touching a grounded metal frame piece in the assembly). This is very important because static can destroy sensitive electronic components such as the ones inside the Fiery.
If there is a lot of dust inside, clean it out gently with forced air. When you use air on a fan, make sure to use a skinny straw or similar tool to hold the propeller from spinning too fast (that can ruin a fan). I recommend that you get some Stabilant 22A. It cleans and coats contacts in connectors/jacks to improve the connectivity so that contamination, oxidation, pitting, etc of the contacts can be overcome and the signals flow can be restored between components to help avoid slow electrical signals that can cause miscommunications (and eventually software corruption). You will want to use Stabilant 22A on both sides of each card or board connection including the CPU to the Motherboard and the Video Board (the one that has the big connector for the Fiery Cable that goes to the printer) and also the memory DIMMs in their sockets. It can't hurt to use it on the fan's connector, HDD connectors, etc. as well. Applying Stabilant 22A will solve some problems if the issue is connectivity at the connectors. If it does not solve the problem, at least you have eliminated that possibility and feel that much more confident that you need to start replacing boards. Note that the CPU Cooling Fan Assembly will be very hot if the unit is on... so make sure you allow the Fan/ Cooling assembly to cool off so you don't burn your fingers. Also, note the orientation of the CPU in its socket. There is a little arrow in one corner that points to where "Pin 1" is ... that needs to line up with Pin 1 on the socket the CPU sits into. Even without Stabilant 22A... removing and reseating the CPU and other connectors might give some temporary relief as the action of removing and reseating can help scrape some oxidation and contaminants off the connector pins so when you reseat them you can get an improvement in connectivity. If, after you clean it all and apply Stabilant 22A to all the connections particularly the CPU under the fan) and the fault continues to come up, then the book recommends replacing the CPU followed by the Mother Board. I think at that point you might be best served by replacing the entire Fiery with a refurbished unit. The price for new boards easily exceeds the price for a refurbished Fiery.
