Image Capture Can't Find Scanner

If you are seeing it in image capture under devices, then it isn’t being hidden from you. There’s a comm error between your computer and the scanner.

As to the drivers, while it is one device, there are two separate drivers, one for each component. The printer side is likely AirPrint compatible, and it sounds as if the scanner side is ICA compatible since it does show up in image capture. I guess my first try would be to restart both the printer and the computer. A second try would be start up your Mac in safe mode and then restart normally.

I do remember something about an encrypted communication error between devices, but I don’t know of any details or if this might be related

It appears that there is only generic support for this device under MacOS. The HP web site offers no HP drivers for MacOS, only Linux and Windows ...

You can use the generic drivers available from Apple but those might not support scanning.

Vuescan provides drivers for many scanners and does support your device:

This device seems quite old and it might not be directly supported under Tahoe (although it still may work), I found this on its HP support area:

• HP Printer Drivers v3.1 for OS X (in English): Supports OS X Mountain Lion and OS X Lion
• HP 5.1.1 Printer Software Update (in English): Supports macOS 10.14, not compatible with macOS 12 and newer

Those are ancient MacOS versions.

HP also says this about this device:

Compatible operating systems 

Windows 11; Windows 10; Windows 8; Windows 8.1; Windows 7; Windows Vista; macOS X 10.7 Lion; macOS X 10.8 Mountain Lion; macOS X 10.9 Mavericks

It might be obsolete with respect to modern operating systems. That said, I have multifunction devices from 2010 and 2015 that still work for both printing and scanning under Sequoia. One of them however has a specific Image Capture scanning driver that is installed from the manufacturer (Epson).

This printer shows up as "bonjour multifunction" with no mention of air print that I can find.

Bonjour is how the printer is discovered so it can be added to the printer list. Since it shows as multifunction, it’s being discovered as a printer + scanner (and maybe fax, too, depending on the printer). AirPrint are the ‘drivers’ that run the printer and scanner when you’re using it.

I have deleted then reestablished the printer several times and even reset the printer according to Apple's instructions. The printer continues to work fine and the scanner continues to be un-findable by Image Capture. The HP.app is able to access the scanner function so I do have that to fall back on. The HP app isn't as functional as Image Capture, especially with exporting/saving images as documents but perhaps that's because I haven't yet discovered the right button.

Odd. Reading your original post, ‘Shared’ is where the scanner should show up in Image Capture (not under devices, that’s for wired connections). I wonder if you had an original connection issue and now the HP drivers are now causing an issue? Your printer launched in 2015, but I have an HP Officejet Pro 8740 that launched a hear after that, and printing and scanning work fine (I have no HP software installed).

When you first had the problem, did you power cycle the printer and try deleting and re-adding it, or were those steps only done after the HP software install?

Have you tried updating the firmware on your printer? On mine, I can do that on the printer itself in Settings > Printer Maintenance > Update the Printer.

I also did a screen video of the relevant window

What window do you consider relevant?

Image Capture recognizes your scanner, thus it is Image Capture Architecture (ICA) compliant and there is some driver present.

Your problem is in the communication between the Mac and the scanner portion of the device which could be an outdated ICA driver.

HP may have an updated ICA driver, but they bundle everything together making it difficult to determine if there is one in the package.

AirPrint, or any printer driver, has nothing to do with scanning even if the two functions are welded together in a single container.

When you click on that Add Printer panel and Apple's Bonjour detects it, you click that line and the Use: selector will automatically choose AirPrint, though it may display the device name and not explicitly AirPrint. The following is how this AirPrint configuration works for my Samsung laser:

Some previous posts suggested issues with port blocking or other security settings on the router. Though I feel like I'm grasping at straws a bit, here.

I believe that the HP Officejet 5740 supports AirPrint, so no drivers should be needed. First step in troubleshooting would be to delete the printer then re-add it.

Else, you can reset the printing system (then re-add as above).

No, my OfficeJet Pro 8740 has a touchscreen, I just navigated around on it until I found the manual firmware update request. The printer downloads firmware directly (presumably from HP), I get a prompt once in a while, press ok and an update is applied. I think most of the recent ones are more about locking out non-HP ink, but still...
