I was wondering if you could make available the HCF file for the Relay 4500 for the OMR C-Fold type.
on your following website: https://help.objectiflune.com/en/#pps-pdc
These can generally be made upon request through Support if you have OL Care. You’ll want to open a ticket to get the process started. Once it’s created, however, it needs to be tested with you and confirmed to be working before it can be posted to the Help site.
That said, Connect itself has excellent support for doing OMR marks via the Output Preset “Add Additional Content” option: PlanetPress Connect 2019.1 User Guide
This is generally considered the better way to go as it is more flexible than the HCF method.
