Source Technologies, LLC ST9612 Secure MICR Printer User’s Guide
28
Your secure MICR printer also contains the MicroPrint font. MicroPrint text, being less
than .010” tall, can be easily read with a magnifying glass but appears as a solid line to
the unaided eye. This font provides protection against reproduction by most scanners
and copiers because they cannot successfully print the tiny letters.
Most check printers use this font in the signature area of their preprinted checks. It is
recommended that this font be used to help deter check fraud. The text in this font can
be either fixed (such as the name of your organization) or it can be variable (such as the
check amount and payee name). The use of variable text provides an additional method
of protection against check counterfeiters.
Use of the “MP” designate symbol to identify the line as MicroPrint is optional. The
MicroPrint font only contains alphanumeric characters. Punctuation marks and spaces
are ignored by this font and do not print.
Resource Storage The Flash memory in the printer contains five Source Technologies’ secured fonts but
can be loaded with additional resources for check or non-check printing. The Flash can
be loaded with signature fonts, overlay Macros, or other custom resources limited only
by the available space. Flash memory in the ST-9612 is read/write password protected.
To load additional resources to Flash requires the proper PJL commands to unlock the
Flash memory device. This will be detailed in Chapter 7.
Storing resources (fonts, Macros, etc.) in RAM is also an option. Resources in RAM are
deleted when the printer is powered off and cannot be password protected in the printer.
A Source Technologies’ secure MICR printer only supports Source Technologies’ MICR
Toner Cartridges. The printer will display an error condition when a standard cartridge is
installed. When a MICR toner cartridge is installed the following occurs:
Control of image density or print density is set to optimum levels for MICR
printing.
When the PJL “MICRJOB” command is sent, the following occurs:
1. The printer forces internal copies to 1. Downloaded copy commands are
ignored.
2. Automatic reprint of jammed documents is disabled, forcing the application to
reprint any jammed documents. This provides an audit trail to the application
of the jam event.
