Printer has no power, no signal
Have you checked the power pack to make sure it works OK? You would either have to measure its output under load (being used by something), or, set this up on a test bench with a meter and some kind of electrical load. The output voltage and current is printed on the power pack's label.
If the power pack is OK, it is likely you will need to have it repaired, unless you are able to open it up and work on it SAFELY. If you are not experienced at troubleshooting and repair of these types of products, you should have it looked at by an expert who is experienced. The prices on these are so aggressive, it may soon become obvious that it would be cheaper to replace it with a new or slightly used one, than to pay someone a high hourly rate, plus parts, to repair it. For example, I bought mine for under $200, and I know that there have been used, refurbished, outlet sale, etc., 6310 or similar printers on eBay for under $100. It is very easy to run up a bill in excess of $100 when attempting to repair something as complex as these printers are. Unless it is something simple and easily spotted in a few minutes, and relatively cheap to repair, the highly modular design of this printer does not lend itself to repairing individual components on the circuit boards, etc. They are replaced as modules, and the modules, like car parts, can be very expensive and hard to get, much more than they ought to be, because of the high cost of maintaining parts inventories and repair personnel.
Hope this helps somewhat; sorry there is no easier solution. However, there are a couple of things you can do just to make sure you don't have a very easily fixed problem.
The first would be to check the power pack, or have it checked by a technician, as I have suggested. Since power supplies are often the most prone to failure in a computer system, and the power supply for 6000 series printers is external, it is relatively simple to check this part. My power pack has a green LED molded into the plug which is plugged into the back of the printer. If that is on, it tells me power is good, and I'd need to look elsewhere for the problem. If you have one of these power packs, and the light is not on, you probably do have a problem with it. If the light is on, your problem is inside the printer.
This printer has "interlocks" which require that the top be properly closed before power will be applied to the circuits etc. Check to make sure you have the top closed securely, and that it does not "float up" after you close it. The top should be very firm and solid; if you press down on it (gently) after you close it, and it moves or feels insecure ("mushy" or makes unusual noises, etc.), try opening and closing it again a couple of times. The mechanical latch could be loose or broken, which would not allow the interlock switches to be actuated, and power would not be applied to the internal circuits.
What do you mean by "no signal"? Do you mean, the front panel does not show signs of life, no lights come on, etc., or something else?
Hope this helps. There is not a lot more to do when a printer is dead, than to start at the power supply and start working your way from that to the front panel. Again, if much repair time is needed, or a major part has failed, you are probably better off to replace it then try to repair it; check for sale prices on the Internet or in your local papers, etc.
