The Audit Trail Report feature provides a report of the printer’s MICR printing activity. 
The printer must have flash memory to utilize this option. Details of each flagged check 
record sent to the printer are provided since the last audit report was purged from flash 
memory.   
Report Details 
A record (check) must be bounded by a start of record command and an end of record 
command. Within each record, fields to be included in the Audit Trail Report must be 
flagged. The printer stores each record in flash memory. After the check is successfully 
printed, its record is designated as a successfully printed document in flash. 
The report is built by printing each of these check records as a line item. At the end of 
the report, an exception report is generated which highlights any records received by the 
printer but not successfully printed. 
Each record (check) has a maximum of seven fields with a total of 146 bytes. Two of 
the flagged fields, SQ1 and SQ7 are Audit Report fields only. They are not printed 
on the MICR document. Flagging other fields for inclusion in the Audit Report does not 
effect how they print on a check.  
Audit Trail Menu 
The MICR menu contains a section for the Audit Trail options. Menu options are Audit 
Location, Record Sorting, Overlay, Sum Field 4 and Print Report. 
Audit Location 
Choose to store audit data on flash or disk. The display will show “No Device” if neither 
is installed. Flash is the default if both are present. 
Audit Record Sorting 
This enables sorting of the report by the first 20 digits in the MICR line field. In an 
unsorted report the records are in the order in which they were printed. 
Overlay 
To assist in reading an Audit Trail report you have the option of using a form overlay.  
This overlay can provide lines, boxes and shading for a more user friendly report format.   
The Audit Trail Report overlay can be stored in printer flash or RAM. We recommend 
storing it in flash. It must have an ID of 5001.  It is enabled by accessing the MICR menu 
via the printer’s front panel.  Select Audit Menu > Overlay. This overlay will now be 
merged with the record details every time the Audit Trail Report is printed. 
Sum Field 4 
The values in field four of the Audit Trail Report can be added together with the total 
provided at the end of the report. This feature is activated through the MICR menu.  
Select Audit Menu > Sum Field 4.
