In the Diagnostics window you can manage the various diagnostic options. Most of these diagnostics can be run with the printer started normally. However, if you experience a severe error in the start-up progress that prevents you from running the diagnostics, an extra start-up mode has been provided for this situation. To use it, press the power button and tap Restart in diagnostic mode. Then the printer will start only a minimal set of components. You can then go to the Diagnostics app and run the diagnostic you need. NOTE: Read the descriptions of the diagnostics and follow the instructions. IMPORTANT: When the printer is started in diagnostic mode, it is unable to print. When you have finished the diagnostics, press the power button and tap Start in normal mode. When you call your service representative to report an issue, pass on the results of any diagnostics that you ran. When you get a message from the printer with a numerical code in the form XXNN-XXXX-XXXX, the NN part of the mode is related to the subsystem, and can be found in the following table. Number 01 10 11 16 17 22 27 41 43 45 46 47 48 49 50 52 55 58 80 86 88 90 Subsystem E-box Power box Printhead control link Curing Drying Ink distribution system Printhead Substrate path mechanics Substrate path vacuum system BIOS Printer ID PCA Printhead cleaning roll Lift mechanisms Carriage aerosol Substrate advance sensor Drop detector Carriage sensors (line sensor) Carriage sensors (spectrophotometer) User interface Scan axis Printhead primers Internal firmware errors NOTE: Some of these subsystems may be available only to service engineers, because they require specific knowledge or for safety reasons. NOTE: In any case we recommend running the Safety Interlocks diagnostic to ensure that printing is not disabled by a safety interlock. ENWW 235
