Test to see if the laser is really on and that the laser power setpoint is reasonable. Try with "laser current", "head bp on" instead of with "laser on" to see if the problem is media set up related or laser / shutter sensor related. Finally, this may indicate a failed shutter sensor. Reset machine and try again. Check media selection. If error persists call service. This error is reported. Not enough light detected on shutter sensor to measure the profile. Possible shutter sensor failure. 03-Jul-2002 ../prm/ehi_hdm_wpower.xmlPRM: hdm wpower ../commands/laser.xmlCommand: laser ../commands/laser_-laser_mode-.xmlCommand: laser <laser mode> ../commands/laser_current_-laser_current-.xmlCommand: laser current <laser current> ../commands/head_bp.xmlCommand: head bp ..\..\ShowAllErrors.htmFirmware 1 Error Index ..\..\ShowAllCommands.htmFirmware 1 Command Index ..\..\ShowAllParameters.htmFirmware 1 Parameter Index Updated: Thu Jul 17 07:23:42 2008 PST
