Toshiba e-STUDIO 655 C260 Error: Laser Failure

The Toshiba e-STUDIO 655 error C260 points to a failure in the laser scanner unit (LSU). The device detects that the internal polygon motor is not reaching the necessary speed to synchronize the exposure of the drum. This stops all printing and copying until the exposure system is repaired.
