5.  MICR Features 

 
Source Technologies’ secure MICR printers are designed to allow both general office 
document printing and secure MICR document printing. You may print a variety of 
conventional jobs with regular Lexmark toner using all of the printer features available 
such as network printer utilities. Source Technologies’ printers support multiple printer 
languages (for example -  HP’s PCL5 & PCL6, PostScript Level 2 emulations). The 
MICR features require the PCL5e print data stream. Source Technologies has designed 
features to enhance these printers with MICR mode specific operation that allows you to 
securely print high-quality negotiable documents. 

 

MICR Mode 

Your secure MICR printer has two operational states: normal and MICR mode. When the 
printer is in normal printing mode, your MICR resources cannot be accessed. Once the 
printer enters MICR mode your secure resources become available and the printer 
begins the process of confirming readiness to print a negotiable document. There are 
two conditions which must be met before MICR mode is activated: 
 

The correct password command must be received by the printer from the 
software application prior to printing any MICR documents. 
  
If the front panel combination lock feature is activated, the correct eight digit 
combination must be entered from the front panel.   

 

MICR Fonts 

The E-13B and CMC7 MICR fonts reside in the printer. Examples of these fonts are in 
the Appendix of this manual. They can only be accessed after MICR mode is activated 
by your software. A MICR toner cartridge must be present to print the MICR fonts. 

 

Secure Fonts 

Source Technologies has designed two fonts: Secure Numeric Font and ICR Secure 
Numeric Font. These are resident in your printer as well. Examples of these fonts are in 
the Appendix of this manual. Like MICR fonts, these secure fonts can only be accessed 
after MICR mode is activated by your software.  
 

•

  The ICR Secure Numeric Font is designed for the convenience area of your 

check. It can be read by the imaging equipment used by many financial 
institutions.  

•

  The Secure Numeric Font should not be used in this area since the reverse 

image aspect of this font prevents it from being read by this equipment.  

 
We recommend using both of these fonts on your checks as they are designed to deter 
check fraud. 

 
MicroPrint 

Your secure MICR printer also contains the MicroPrint font. MicroPrint is text less than 
.010” tall. It can easily be read with a magnifying glass but appears to be a solid line to 
an unaided eye. This font provides protection against reproduction by most scanners 
and copiers because they cannot successfully print the tiny letters.
