multipage scan aborts after 15th page

I am trying to scan a 15 page document to a single PDF file.

I scan 14 pages successfully using HP Smart 95.1.531.0.

Then I activate the "Scan" process for the 15th page, upon which HP Smart closes down. The scanned pages have not been saved.

I have done this process twice with the same outcome.

I am reluctant to spend another 20 minutes trying again to get the same result.

Any explanations or suggestions as to how to overcome this issue?

I have resolved this myself by installing the full featured software, after an on-line (Whatsapp) chat with an HP support person.
