 33
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. 
Flash Memory is an optional feature. 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. 
 MICR Menu Your Secure MICR Printer contains a front panel menu specific to MICR applications.  
The complete menu is as follows:  
Option Card Menu > MICR Menu 
Security Lock 
Audit Menu 
  Audit Location - Flash/Disk 
  Record Sorting 
  Overlay 
  Sum Field 4 
  Print Report 
Setup Menu 
  MICR Type - Normal/Optraforms 
  Hex Transfer 
  Density Control 
MICRpoint 
Use the menu button on the front of your printer to toggle through the menu options. To 
select an option press the select (√) button. An item is selected when it has an asterisk 
(*) after it. 
The Security Lock option allows the user to activate and set a front panel combination 
for additional security. This feature prevents anyone from printing checks without the 
proper 8-digit combination. See the MICR Mode Commands section of this chapter for 
more information.
