RESTRICTED USE ONLY Fargo Electronics, Inc.HDP600 High Definition Card Printer/Encoder User Guide (Rev. 2.3) 10-4Resolving the FPGA ErrorSymptom: An unexpected hardware error has occurred.Step Procedure1 Reboot the Printer.2 If the problem persists, the Main Print Board will need to be replaced.3 As an alternative to replacing the Main Print Board, the chip U34 may bereplaced. (Note: Fargo recommends that only a qualified electronicstechnician perform this procedure.)Sensor TestingStep Procedure1 Check the voltage to determine if a Sensor is working.2 a. Test the voltage of each Sensor using ground (GRD = Chassis) to thecorrect pin on each connector. See Sensor Location and Voltagestable below).b. Block a slot Sensor with a card.c. Cover a reflective Sensor with a card.3 a. Troubleshoot the Ribbon Sensor by using the RibbonTraq marks on theRibbon and Film to cover the Ribbon and Film Sensors. (Note: Thenumbers indicate the location on J9, as shown in the Sensor Locationand Voltages table below).b. Open the upper Module to find the Ribbon Sensor orientation. (Note:The numbers indicate the location on J9, as shown in the SensorLocation and Voltages table below.)
