12007 Power Supply Failure POWER: Exposure Head power All VLF: Check the safety loop under mask. Head mask will not be available since this error relates to ps6 which is the exposure head logic power. Check the led's on ps5 and ps6. AC ok and DC ok should both be on. Measure the power at the outputs of ps6 it should be 48V, also confirm that there is 240V at the input. If with ps6's output connected there is 48V then measure the voltage at the thermal head, if it is 0V then replace the eh pwr cable. If there is 240V input power but no 48V, power down the device and disconnect ps6's output connections. Next, turn on the device and measure the power at the output of ps6. If the output is 0V then ps6 needs to be replaced. To check if the thermal head needs to be replaced as well ps5 can be swapped with ps6 to verify if ps5 has 48V when the output cables hooked up. If the output is now 48V the thermal head is fine. If the input power is not 240V but the carriage and drum operate normally then check fuse F8 on the power distribution board. This cuts the AC to the connector at J16 which feeds ps6. Shutdown trendsetter. Power on Trendsetter. Check for open doors. Call service. Known causes: Failed fuse, Power Supply failure, Thermal Head failure. ..\..\ShowAllErrors.htmFirmware 0 Error Index ..\..\ShowAllCommands.htmFirmware 0 Command Index ..\..\ShowAllNVS.htmFirmware 0 NVS Index Updated: Wed Jul 16 19:32:42 2008 PST
