Understanding Fatal Errors
There are two types of fatal errors, flash write errors and EEPROM
configuration block errors. These errors are extremely rare, but
measures are built into the printer diagnostics to track possible
occurrences.
Flash Write Errors
Errors related to writing or erasing flash are critical errors. These
errors cause the printer to stop all processing and produce an LED
code and a sequence of beeps. The LED code indicates the address of
the segment where the error occurred in octal notation.
The octal digit changes every four beeps until four octal digits are
output. Only four octal digits are output since blocks are 256 bytes in
size and flash can be addressed with a total of 0x7ff blocks. The
segment address output is the runtime address of the flash block and
not the offset of the block within flash.
To obtain the block offset within the flash
Subtract 0x800 from the address output to determine the block
offset.
The printer suspends after the processing the error code. When the
printer resumes, an error again and the printer suspends again. Reset
the printer to correct the error. If a reset does not correct the error,
have the printer checked by a qualified service technician.
