I have an HP 8620 all-in-one wireless printer, which has worked like a champ for months under Windows 8.1 and Linux. I recently upgraded to Windows 10. My wife is still on Windows 8.1, and she is seeing this problem as well. All computers can still print to the printer.

Restart the PC. Once the PC is on the desktop, press Win + R, it would bring a Run dialog box, Type%temp% in the run box and click Ok or hit the Enter button. It would bring up the temporary files folder. Delete the files in the folder (You might not be able to delete all the files.

However, both the Win 8.1 computer and the Win 10 computer have started showing messages about 'Unable to scan computer - printer disconnected.' These message show up periodically on both computers, and are rather annoying.

1. Fix: Scan to computer is no longer activated If the issue is with your Computer or a Laptop you should try using Reimage Plus which can scan the repositories and replace corrupt and missing files. This works in most cases, where the issue is originated due to a system corruption.
2. HP driver for the HP Officejet Pro 8600 that allows you to scan from the printer to your computer over the network. This startup entry is started automatically from a Run, RunOnce, RunServices, or RunServicesOnce entry in the registry.%ProgramFiles% refers to the Program Files folder.

One post I found suggested it had to do with the printer going into some sort of power saving mode. That doesn't appear to be the case, as the printer was on, and able to accept print jobs, and I was still seeing this message pop up.

I've tried updating the drivers from HP, no noticeable change.

How do I clear whatever status is making the computer think this feature is no longer working, or at least shut up the warning about it?

This is for Windows 10. Open task manager, go to Startup, scroll down to 'scan to pc activation app', right click on Status 'enabled', choose 'disable', reboot..worked for me.

I have a HP Officejet Pro 8600 and one can disable Scan to Computer in the accompanying app: just click on the printer shortcut that was created during installation, go to Manage Scan to Computer, and then disable the feature and uncheck the Automatically start Scan to Computer when I log on to Windows box (in the picture below, I've already disabled this feature).

If you cannot find the shortcut: the app's default path should be 'C:Program FilesHPprinter nameBin'.

This feature does not disable scanning from your computer - this works totally fine. It's only purpose is to to send a scanned document directly to the computer where this service is running when you scan at the printer - which is useless for me, personally.

I found the answer to this issue in the HP forums:https://h30434.www3.hp.com/t5/Scanning-Faxing-and-Copying/Scan-to-computer-is-no-longer-activated-again/td-p/3465249

I've had the very same problem after upgrading to Windows 10, although with A8500.

What did was the following:

Scan To Pc Activation App Fix On Windows 10

• Make sure the printer is on (standby is OK).
• Open the HP All in One app and remove all printers/favorites showing up. Close the app.
• Remove all copies of the printer in case multiple exist, local and networked. Check the devices section in the new settings app as well as the classic 'Printers & Devices' section of Control Panel. Uninstall the drivers through the context menu.
• Reopen the AoI app and search the printer, add it, and mark it as favorite.
• Wait for the prices to complete. You'll get that annoying pop-up as long as the printer isn't showing up as connected.

Two more notes:* As an alternative solution, uninstall the AoI app.* This issue has nothing to do with the printers standby mode. The network interface of the printer always stays online to turn it on for printing.

Falcon 4 boot iso. Mar 31, 2013  FalconFour’s Ultimate Boot CD/USB 4.6. I needed to rename the Falconfour iso name to Hiren’s Boot CD to get the installer to point to that iso. Worked great! Use yumi instead. I’m still having to keep an old falcon disk around for the xp recovery console which I routinely use to write a new MBR after a virus. Contact Info Matt Falcon. Fresno, CA USA.

When your computer is acting up, such as won’t boot, boot with blue screen/black screen, or when you’re locked out of your account, one of the best ways to diagnose and examine PC problems is to use a bootable disk.

My solution for this problem was to turn off my printer and turn it back on again. I had two computers that both said that the scan to computer was no longer activated. After I did that, the two different pages I tried to print were immediately printed from the printer. I think the address changed somehow on the printer and it needed to be rebooted back up for the computers to detect it properly. That is what worked for me.

Running Windows 10 Anniversary Edition, I started receiving this message after installing the HP ENVY 5640 software for one of our network printers.

I found the program 'ScanToPCActivationApp' in the 'C:program filesHPHP ENVY seriesbin' directory.

Htc windows phone 8.1 price. I renamed it by adding 'do not run' at the end of the file name. I then opened task manager, found the running app in the 'Background Processes' section. A right click on the name opens a menu with the 'End Task' option. Clicking on that stopped the process.

With the name changed, the process cannot be started and the problem is eliminated.

If I ever find that it is needed, it will be very easy to rename and restart. Another option is to create an 'Archive' directory (folder) in that location and just move the file there.
