Using Windows explorer, go to the \Orion\Clients folder on the Orion server. 

Click on the IDAutomation_MICRFONTAdvantage.exe program and run it on the workstation.

This should load the proper fonts for MICR to use. 

Note that you may need to double check that the proper MICR font is assigned correctly for the MICR object itself in the style. If it is not, which may be due to copying the style from another firm or it being used for the first time, you will need to assign it to the object correctly.  See the article MICR setup in Check Style.

Note that these instructions pertain to installs where fonts are loaded on the workstation and not on the special printer card that is installed in the printer itself.
