BJC-50
If you get a rewrite error, reset the following:
Error message
DATA error
FLASH error
RAM error
Follow these procedures when an error occurs:
DATA error:
Occurs after each rewrite data has been transfered. Hence, data prior to the error is
already rewritten.
Make sure that the floppy disk corresponds to the printer model. For example, do
not rewrite data for BJC-50 with BJC-50v's. To transfer the correct data, check the
connection with the computer and re-enter the rewrite mode and repeat the steps.
FLASH error:
Occurs after each rewrite data has been transferred. Hence, data prior to the error
is already rewritten.
Re-enter the rewrite mode and transfer the connect data. If the same error recurs,
the flash ROM might be damaged. In that case, exchange the control board.
RAM error:
Occurs when the printer goes to check for available RAM to operate rewrite. No
rewrite has taken place at this point. In this case, exchange the control board.
