Remove the toner cartridges, check for any stuck fragments of paper, and clean out the inside of the printer.
Fit the toner cartridges back in place, start the printer.
If the problem persists, press the C button for 2 seconds.
If all of the lights are still flashing continuously, then the printer will require a service.
