Jam Detected 5 Blinks
Missed Top of Form 6 Blinks Paper LED will blink fast.
Illegal or Bad Command 7 Blinks Paper LED will blink fast.
Printer Over Temp 8 Blinks Fault LED will blink slow.
Bad Power 8 Blinks Fault LED will blink fast.
Hard Errors
Hard errors have a similar blink pattern to soft errors, except that they are slower and
repeat every 10 seconds. In general, these errors occur during level 0 diagnostics
and are not recoverable. In these cases, the Error and Power LEDs will blink at the
same time.

Auto Error Recovery
The Epic 880TM printer has the ability to auto recover from some internal errors.
Flash Format Errors
The internal flash that is used to store graphic images is formatted to assure data
integrity. If this format is corrupted, the printer will automatically delete and reformat
the flash. The host can then reload the images.
Input Power Fault
The printer monitors the power input to the printer. If it is found to be greater than 26
volts or less than 20, the printer will stop and wait for the power to return to
specification.
Head Temperature Fault
The printer monitors the head temperature. If the head temperature is greater than
60º C, the printer will start to slow down. If the head exceeds 65º C, the printer will
stop. The printer will heat the head to maintain a head temperature of 25º C. If the
printer cannot maintain a head temperature of 0º C, the printer will stop. In all cases,
the printer will automatically recover when the head temperature is within range.
Configuration Fault Recovery
The printer maintains an operating configuration in EEPROM. Information such as the
printer’s serial number, operating configuration, and running totals are stored in this
memory. Each section of this memory maintains a check character to signal that the
data is valid. If this memory is found to be corrupted, the printer will restore it based
on a backup copy saved in flash. This flash copy is generated when the printer was
