Hi dradford,
Thank you for using the Support Forum. I did a little search on one of the Fuji sites but was unable to find the exact model you reference. The only help I can offer is the Scan Specifications for the DocuCenter C4470. I am not sure this is what you are looking for so please consider contacting your support centre for further assistance.
Do you have any documentation or information relating to the scan to PDF function? Specifically, I'm looking for details of the PDF spec tyou are using and how you implement it. We run some post processing on our PDFs and have encountered some issues solely with the documents created by the Fuji Xerox FXC4470.
