Difficulty adding the signature on AP Check XMLP in PS 9.2.

Hello all, we are having difficulty adding the signature on AP Check XMLP in PS 9.2. We were able to reformat the template CHECK1_CHECK.rtf and move the fields around and add the MICR fonts but could not figure out how to add the signature. It is surprising how there is no documentation for this important task. Any help is greatly appreciated.

Thanks
