Scanner problem; failed to open a session

[CJEsag]

I have OSX 10.10.5

Printer: photosmart D110a

Today is Oct 31, '17

My scanner worked Oct 18, '17.  

On Oct 25, '17, I allowed the computer to install HP Printer Software Update version 5.1

Today I tried to use the scanner but after several seconds of trying it gives the message "Failed to open a session on the device."

You can see a screen shot here:

The printer still works.  I printed some things before attempting to scan.

I've restarted the computer and the printer.

I've repaired the permissions on the computer

I installed HP-ePrint_v2.5.0.dmg

I wouldn't mind just undoing the software update but my searching hasn't found a way to do that or the solution to this problem.

Any help is greatly appreciated.

Hello, @CJEsag - Greetings!

Thanks for accessing the HP Support Forums for extra support! I see that you are experiencing trouble while scanning with your Photosmart printer. I will do my best to assist you with this issue 🙂

I would suggest you use “HP Easy Scan” so that you can scan from your computer. HP Easy Scan is a free app from the App Store with tools to scan documents and photos to a Mac running OS X 10.9 or later. Please install it here: http://apple.co/2lsPpwU 

Also, check http://hp.care/2d75fhX to get detailed instructions to scan and also to change the settings while scanning.

Please let me know whether that works for you. Thank you!

Cheers 🙂

Are you kidding me?  Over 75% of the people who have tried it DON"T like it.   The latest update was for performance and stability.  It appears I have no choice because it doesn't sound like anything will be done to get my OS-X software to work with my HP printer/scanner.

I used to feel HP was top of the line.  That's not my feelig right now.

OK  I tried it.  Same problem.

"Failed to open a session  on the device."

Hello, @CJEsag

Appreciate your efforts! 

Try the steps below to try and fix the issue:

• Uninstall the old printer drivers first. Follow the steps mentioned here: http://hp.care/2cKwLyC
• Now run the Apple Software Update. Check here for steps: http://hp.care/2cNgw3C
• Restart your computer and printer.
• Click the Apple menu icon, and then click “System Preferences”.
• Click “Printers and Scanner” / “Print and Scan” or “Print and Fax”.
• Right-click the blank space in the Printers list, and then click “Reset printing system”.
• Click “Reset” in the confirmation window.
• Enter an administrator username and password, and then click “OK”.
• Wait until the printing system is reset and no devices show in the Printers list
• Now, click http://apple.co/2noCAoI  to download and install the printer driver.
• In the “Add printer” window, make sure you add the printer as mentioned below:

1. Click the “Add button” (+).
2. Find, and then select the name of your printer from the printer list, and then click “Add” to add your printer.
3. Click “Print Using...”, and then select the name of your printer (By default “AirPrint” would be selected)

Let me know if that helps!

Good luck 🙂

I have the same problem with an HP 8720 on Max OSX 10.12.6 (Sierra).

I went through the suggested steps to remove the printer, restart, update, install HP printer drivers, add printer.

I still can't scan using "Scan to computer" from the printer, but the message has changed from "Failed to open a session" to "The scanner failed to complete the scan".

It's very frustrating.

I checked the system log for events containing the term "Scan". Looks like there's something here that could identify the problem...

> log show --predicate '(eventMessage contains "Scan")' --style syslog --last 1d
