HP Scan to OfficeJet Pro 7740 from Windows 10 OK. Readiris scan won't work.

HP Recommended
HP OfficeJet Pro 7740
Microsoft Windows 10 (64-bit)

Software initially installed from CD. Readiris Pro 14 reported HP TWAIN error. Using wireless connection 6 ft. from router & printer. Tried easy actions: restarts, verified scan ability with HP Smart OK. IP address appears OK but I'm not expert. I have not disabled firewall. I have loaded Readiris Pro 16, no change. I have attempted to upload drivers. Error. I have asked HP Dr. to fix - errors & no answer.  I have been working this over several days and I am still unable to resolve. I tried HP virtual assistant - not helpful. Can you help?

Hi,

Thanks for using the HP Support Community.

 

Do try these steps in the order stated:

 

1. Install the HP FULL solution software

https://support.hp.com/us-en/drivers/selfservice/swdetails/hp-officejet-pro-7740-wide-format-all-in-...

 

2. After a successful install, then download and install the ReadIris pro ver16.0 software:

https://support.hp.com/us-en/drivers/selfservice/swdetails/hp-officejet-pro-7740-wide-format-all-in-...

 

The order of the install needs to be HP FULL software first then ReadIris.

 

Hope that helps!
