Print Unable EC

I tried to clean the printer prior to replacing the toner cartridges. Then replaced the toner cartridges. Turned on the printer and tested printing. The machine printed once, then an error came up stating "Print Unable EC". I tried every thing to fix it, but no success. One of your viewers said that the error is related to the machine fan. I tried to feel if air comes from the fan, there is no air coming out. How could I open the machine to check the fan?
