Troubleshooting How to read the Formatter LEDs The LEDs located on the Formatter can help to troubleshoot the printer. The LEDs can either be on or off; different combinations can indicate different problems. The following image shows the three Formatter LEDs, which are numbered from the top down: number I at the top, number II in the middle, number III at the bottom. Use the following table to interpret the LEDs and find the source of the problem. Remember that you should read these LEDs when you push the Power button. Some combinations may require you to replace two or more components. In this case, always replace one component at a time.
Test the printer to see if the problem has disappeared (check the LEDs again). If the same LED sequence continues, replace the next component indicated in the table. 14 Chapter 1 Troubleshooting ENWW Power amber LED Power blue LED Power green LED Formatter I LED Formatter II LED Formatter III LED Front panel status Problem and recommendations Off Off Off Off Off Off Off The printer is not receiving electrical power. 1.
