Thermal 3 Errorcode: [05211] Timeout waiting for the write laser to be detected


Service Information	To protect the exposure head, initially the laser current is limited to 120% of the threshold current for each laser diode. The beam-pointing driver then attempts to begin tracking the write laser. This error code indicates that a timeout has occured waiting for the beam-pointing driver to begin tracking the write laser.
Operator Action	Call service.
Causes	The threshold current is too low. A hardware failure of the exposure head.
