17021 Exposure Head HEAD: break detected, exposure head has reset Thermal The exposure head to backplane (EH-BP) cable should be checked. The exposure head's digital board should also be checked (parameters stored in EEPROM must be restored if the board is swapped). Check that the board has +5V. If there does not seem to be any hardware problem, an exposure head firmware bug may have caused the crash. The Platesetter should be rebooted. Reload the head firmware and LCA bundle, particularly if this error follows a firmware upgrade or downgrade. Even if these actions clear the problem, Creo Service should be contacted. Exposure head reset with "head reset" command Faulty EH-BP (exposure head to backplane) cable Exposure head digital board faulty or not mounted correctly Faulty head Exposure head crashed or reset due to head firmware bug Faulty power supply (low +/-12V). Head firmware or LCA bundle not loaded completely, or corrupted. ..\..\ShowAllErrors.htmFirmware 0 Error Index ..\..\ShowAllCommands.htmFirmware 0 Command Index ..\..\ShowAllNVS.htmFirmware 0 NVS Index Updated: Wed Jul 16 19:33:34 2008 PST
