Operational Procedures
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.
EEPROM read fault | 2 Blinks |
EEPROM write fault | 3 Blinks |
Error Vector Taken | 4 Blinks |
Knife Error | 5 Blinks |
User Store Format Error | 7 Blinks |
User Data Store Error | 8 Blinks |
Flash Read/Write Error | 9 Blinks |
Memory Error | 12 Blinks |
Com Adapter | 14 Blinks |
Kernel Fault | 15 Blinks |
File system Fault | 16 Blinks |
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. volts or less than 20, the printer will stop and specification.
If it is found to be greater than 26 wait for the power to return to
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
