17724 Exposure Head HEAD: Laser beam positioning not stable yet Thermal An attempt to turn on the laser beam (ie with "laser on") before the beam positioning has stablized will cause this error. In this case simply try again. It may be necessary to initially start the laser with "laser on", "head bp on" initially if the stored thermal rod hold current is way off for some reason. If problem persists and you have thermal head version greater than 1.56 it is easily possible to diagnose the exact problem by using the internal data collection capabilities (see release notes or head diag0 information). Also with 1.56 the command "laser test" may diagnose the problem. Cancel current job and try again. If the problem persists, call service immediately. Beam pointing is too far off to start the laser within the laser on timeout. In this case trying again will likely fix the problem. If the beam positioning servo is not working properly, the laser will never be able to be turned on successfully. ../commands/laser_on.xmlCommand: laser on ../commands/laser_current.xmlCommand: laser current ../commands/head_bp.xmlCommand: head bp ../commands/laser_test.xmlCommand: laser test ../nvs/head_cfg_diag0.xmlNVS: head diag0 ..\..\ShowAllErrors.htmFirmware 0 Error Index ..\..\ShowAllCommands.htmFirmware 0 Command Index ..\..\ShowAllNVS.htmFirmware 0 NVS Index Updated: Wed Jul 16 19:33:44 2008 PST
