Error Codes Unrecoverable Error Codes Display error code on LCD: "ERROR CODE: XXXX-XXXX" The unrecoverable error codes are coded and refer to the printer module that is experiencing a failure. Some of the codes in the list below have a comment "Not Used". These codes are only for development purposes and should no longer be triggered by the firmware. We do supply the full list of unrecoverable codes because experience told us that under some unique circumstances some of the development codes will still be displayed. Error No Error Message 111 RED_NO_ERROR 112 NONSPECIFIC_ERROR System/Selftest Errors 121 ASSERT_ERROR 122 SAMPLE_ROM_TEST_FAIL 123 FULL_ROM_TEST_FAIL 124 FRONT_PANEL_ERROR_TRAP 125 STACK_SIZE_TOO_SMALL 126 RAM_ADDRESS_TEST_FAIL 127 DEMO_MSG_Q_CREATE 128 PROCESSOR_FAULT 129 UNUSED_INTERRUPT_HIT Comments Error Meaning Standard error trap (no additional information). Assert will display additional information: the first extended code displayed (after the "121") is the file number that represents one of the source modules in the system. File numbers are enumerated in AssertFilesPub.h. The next one or two extended codes represent the line number within the file that holds the assert() statement that failed. One addition extended code is used if the line number is 999 or less, and two extended codes if the line number is 1000 or greater.
