Resource Storage
Check-related resources, such as form overlays and signatures, are stored in your
printer with unique identification numbers. ID numbers must be less than 32767.
Number 5001 is reserved for the Audit Trail overlay. Your secure MICR printer has two
areas where you may store these resources: flash and RAM memory.
The ST9720 secure MICR printer has 256 megabytes of resident flash memory. It is
user-managed and its resources can be designated as “secure” or “unsecure.” Secure
resources are loaded to flash with the STL command and have ID numbers greater than
or equal to 10000. They can only be accessed by using the STP command when the
printer is in MICR mode. Unsecure resources do not require a password and should be
assigned an ID number less than 10000. Resources stored in flash memory are not
deleted when the printer is powered off. Flash memory is required for all audit trail
features.
Storing resources in RAM is also an option. Resources in RAM are deleted when the
printer is powered off or reset. For this reason, check-related resources may need to be
loaded frequently. Resources stored in RAM cannot be password protected.
We recommend storing all check-related resources in secured flash memory.
