Indicator Light
Error Indication and Blink Patterns
The EPIC 3000 printer will blink the LED indicator to indicate various modes or faults.
The printer may be in normal operation, self test or in recovery modes. The multicolor
Indicator LED will indicate which mode by a unique color and or blink pattern.
Maintenance Mode
In Transact boot load mode, the power LED will blink two or more times and then
delay. It will repeat this cycle about every 2 seconds.
If in an error condition, the indicator will be read and blink green an error code.
Self Test Mode
When the printer is in self test, the power indicator will blink slowly with a 50%
duty cycle at a 2 second rate.
Normal Operation
During Normal operation, the Power LED will remain on unless an error is being
indicated. There are two classes of errors, soft errors and hard errors. Soft
errors are recoverable without power cycling the printer. Hard errors cannot be
recovered from without removing the power from the printer, correcting the
problem, and reapplying power.

Soft errors may be recovered by the host, or by opening and closing the
printers cover. All of these errors are indicated by a 5 second repeating
blink patterns.

repeat every 10 seconds. In general they occur during level 0 diagnostics
and are not recoverable.
