Please confirm the fault code - is it 095-651 or 092-651?
Ok, 092-651 means that a there is an error with the Colour Toner Density (CTD) Sensor.
Usually this is just caused by a buildup of toner on the sensor, and cleaning out any excess toner from the printer resolves this fault code.
Try cleaning it out with a vacuum cleaner and let me know if that works?
Ok thanks for the update.
Let me know how it goes...
