• Checking GPIO channels. At this stage, the Printer reads and checks the default GPIO values in the Interconnect PCA when all the cables are connected and all the sensors give the default value or the current state. The results will be displayed on the Front Panel and you can press any key to scroll through the information. If any of the channels cannot be read, the Front Panel will display System Error Code 01.0:10 . For more information on troubleshooting this error code, refer to page 47. If any of the read values do not match the expected default, the Front Panel will display System Error Code 07:10 . For more information on troubleshooting this error code, refer to page 50. 20.
A message will appear on the Front Panel asking whether you would like to check the Carriage Communication. Select Yes or No by using the Up and Down keys and press Enter to confirm your selection. If you select No , the printer skips this test and goes to the next one: 21. If you select Yes , the following message will appear on the Front Panel: Tests and Utilities 22. Open the Window, position your head as close as possible to the platen in order to check if the Carriage power light is ON (a green light on the carriage PCA). Select Yes or No by using the Up and Down keys and press Enter to confirm your selection. NOTE:
To be able to see the LED, you have to place your head very close to the Platen but if you are not comfortable doing that you should remove the Right Cover before starting the test. 110 Chapter 4 Service Tests and Utilities
