1. When only the Amber LED is On:
●
The printer has been switched Off from the Front Panel (after having pressed the On/Off
button).
●
The Power Supply Unit only delivers a 5 V “Standby”; power that is needed to restart the
printer after the Front Panel On/Off button is pressed (the Formatter will start the printer).
2. When the Blue LED is On: Deliver standard “ATX” power for the Electronics Module PCAs
(+12V, +5V, -5V, -12V and so on). All the functions of the Electronics Module are fully operational
(Embedded Web Server and so on).
3. When the Green LED is On: Deliver “analog” 24V and 36V to enable printing.
If you turn on the printer at the front panel, and the Blue LED does not come on, there is a problem.
Turn off the printer using the switch at the rear, then turn it on again using the same switch. If the Blue
LED still does not come on, replace the Power Supply Unit.
If the Blue LED comes on this time, you will probably see an error reported on the front panel as the
printer starts up. If no error is reported, but you continue to have problems when turning on the printer
from the front panel, see
How to read the Formatter LEDs on page 16.
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.
