Service manual

nnn07 “INVALID GROUP”
Group is not part of set.
Check to see that the proper barcode is printed on the page and that the
barcode matches the specifications.
Check to see that the proper barcode job is selected.
Check read setup again.
Check for correct feed speed.
Check speed sensor for proper operation.
Check for failure on the CPU, replace as necessary.
Bad UARTs (Universal Asynchronous Receiver Transmitter) Serial chip
Bad software.
nnn08 “EXPECTED PAGE ONE”
If pages are sequencing up, the software expects the first page of each
set to be either a 0 or 1 (depending on what minimum page number was
selected in the page setup).
If the page was page 1, check to see that the proper barcode is printed
on the page and that the barcode matches the specifications.
Check to see that the proper barcode job is selected.
nnn09 “GROUP NUMBER OUT OF RANGE”
Group code was not in specified range (i.e., 1-7)
nnn10 “PAGE OUT OF RANGE”
Similar to "Group Number Out of Range" error (page range must be
within 1-7)
nnn11 (NOT USED) “INVALID!”
Invalid command
Cycle machine power
nnn12 “NOT ENOUGH NV-RAM”
The program has run out of non-volatile ram.
You should never get this error. If you do get this error, either the
software is bad or the CPU board is bad.
nnn13 “PRESETS CORRUPT”
Some of the preset parameters have fallen out of their defined maximum
or minimum range.
If new EPROMS were just installed this error might occur. If this is the
case, ignore the error.
If the battery jumper was pulled from the CPU board this error might
occur. If this is the case, install the battery jumper and ignore the error.
If neither of the previous scenarios happened, the CPU board is probably
bad.
nnn14 “NV RAM FAILED”
Data in the non-volatile ram was changed
Power to the CPU was unplugged directly at the board
Noise in the 120 VAC power
nnn15 “DUAL PORT RAM FAILED”
Hardware failure on reader board
Battery failed or battery jumper missing
Bad CPU 586 board
nnn16 “INVALID COMMAND”
Hardware failure on reader board
Battery failed or battery jumper missing
Bad CPU-586 board
