Update your post to include full system hardware specs and OS information.

How old is the printer? USB connection to host computer - correct?

Any other noted USB device problems? Test printing/scanning on another known working USB port.

Have you tried another known working USB cable between host computer and printer?

Have you tried reinstalling the HP drivers and scanning software?

Manually download drivers and software via HP's website, reinstall, and reconfigure.

How old is the printer? USB connection to host computer - correct?

1. Printer is a few years old, not sure. It's Color Laser Jet Pro MFP M177fw
2. Yes, USB.

Any other noted USB device problems? Test printing/scanning on another known working USB port.

1. No other problems. Printing works fine. Different port makes no difference to problem (scanning only is problem)
2. Scanner works in Windoze from same computer, cable, port, printer/scanner

Have you tried another known working USB cable between host computer and printer?
1) Different cable makes no difference to problem (scanning only is problem)

Have you tried reinstalling the HP drivers and scanning software?
1) Yes, reinstalled hplip, no improvement.

 

[Ralston18]

Open Reliability History. Take a close at the error codes, warnings, and informational events to date via the timeline format.

Attempt to do a couple of scans.

Then look for any additional Reliability History errors that were logged with respect to any failed scan attempts.

Have you been to the Ubuntu forums? There's plenty of talk about this very issue there. Here's just one:

https://askubuntu.com/questions/1030926/ubuntu-18-04-doesnt-see-the-hp-scanner

There's quite a bit of work to do on those older versions of Linux. Lots of work has gone into getting PnP to work better in the past several years. It might behoove you to look at getting more current.
