Hello @DonJames
Thank you for reaching out on the community and telling us about your issue. I do apologize for the issue you're having. I'm wondering here even though it's not a printer if we might be able to reset the printer settings to see if we're able to clear up this error. In the top right select file > file operations > validate and repair > reset all Quicken Printer settings.
This is a good step to try since they're in a similar realm of product. Once you've done this try adding seeing if you're able to get the scan consistently. Let us know how it goes!
Thanks,
Quicken Francisco
