[Caution] • During sending block data (maintenance counter value), real-time status and ASB status shall not
be sent. Thus, during sending the data, printer status can not be notified.
• Counter value sent by this command is only a guideline value. Due to an error occurrence and
power off timing, figure data may have an error.
• To update the flash memory, write the flash memory if any change occurs in the
maintenance counter when the period where the printer is not in operation (printing,
paper feeding, drawer, or cutting) lasts about 10 seconds, 2 minutes, and 1 hour.
• If change occurs in each counter, data on RAM is updated correspondingly.
