Error Occurred While Communicating With The Scanner

[FlyerRM]

I have had the printer for awhile and was able to scan to my computer wirelessly in the past.  Now, I can't.  I get the error, "Scanner reported an error.  An error occurred while communication with the scanner."    I use a iMAC M4 running Sequoia 15.3.1.  The printer and PC are connected and I can print and copy fine.  I have unplugged the printer and turned it on and off.  I have removed the printer from my MAC and reinstalled it multiple times.  I've downloaded the HP Easy Start s/w and went through the install process with no change.    My wife has an new MAC Book Pro with the M2 pro micro running the same s/w and it works fine for printing and scanning.   I've notice the post for this issue for a windows system and the process to perform a root level uninstallation for the printer driver.  Can that be done for a MAC and if so, can someone share the process?  I'd like to get back to wirelessly scanning to my computer?

@FlyerRM, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

Check Network Connection

• Ensure both the printer and your iMac are connected to the same Wi-Fi network (Setup > Network > Wireless Settings).

Restart Both Devices

• Power cycle both your printer and iMac. Turn off both devices, wait 30 seconds, and turn them back on.

Update macOS and Printer Software

• Make sure your macOS is up to date (System Preferences > Software Update).
• Go to the HP website and download the latest printer driver for macOS Monterey.

Remove and Reinstall Printer

• Go to System Preferences > Printers & Scanners on your iMac.
• Remove the HP OfficeJet Pro 8715 by selecting it and clicking the minus button.
• Re-add it by clicking the plus button, then selecting the printer from the list and ensuring it's the wireless version.

Reinstall HP Smart Software

• Download and install the latest HP Smart software from the Mac App Store or the HP website.

Check Scanner Settings in HP Smart

• Open HP Smart and ensure the scanner is set to connect to the printer correctly.

Run HP Printer Diagnostic

• Use the HP Print and Scan Doctor (available from HP's support website) to diagnose scanning issues on macOS.

Check for Conflicting Software

• If you have any firewall or security software installed, disable it temporarily to check if it’s blocking the connection to the scanner.

Reset the Printing System (Optional)

• Go to System Preferences > Printers & Scanners.
• Right-click anywhere in the printer list and select Reset printing system.

Test Scanning with Another Application

• Open Preview or Image Capture and try scanning directly from there to check if the issue is isolated to one app (like HP Smart).

Check Firewall/Network Settings

• Go to System Preferences > Security & Privacy > Firewall and make sure it’s not blocking printer communications.
• Check your router’s settings to ensure no firewall or network restrictions are blocking communication between the printer and your iMac.

I hope these steps help resolve the issue
