HP Scan to PC is disconnecting

[Petr5192]

Hello,

I have a problem with scan to PC app. Printer is in a small office (5 people). Scan to PC randomly fails - sometimes it is several times per week and somtemice several times per one day. Printer can't see computer and Scan to PC app installed on the computer shows an error: Function scan to PC is unaviable. I have to click on - repair, enter administrator credentials and then it is OK.

It is really annoying and we need it to be working fine.

I already tried:

Reinstall the PC app

Update firmware

Make reservations on DHCP for the printer and other devices

I would like to ask for help. I wrote a ticket to HP support, but I've got no answer.

Thank you.

Hi! @Petr5192, Welcome to HP forums.

I understand you have issues scanning to the computer and you are getting error scan to computer unavailable on your printer.

Don't worry I'd like to help you out.

Did you make any changes to your printer?

Did you encounter the error message while scanning?

Try the steps recommended below.

On your keyboard, press Ctrl + Shift + Esc keys at the same time to open Task Manager. Here we will do some settings under both Process tab and Startup tab.

Find scanToPCActivationApp under Processes tab.
Then right-click on it to choose End task.

Find scanToPCActivationApp under Startup tab.
Then right-click on it to choose Disable.

Restart your PC.

Also, try assigning a static IP to your printer.

In the search type Devices and Printers. Open devices and printer.
Click Add Printer.
Select Add a network, wireless, or Bluetooth printer, then click Next.
Select The printer that I want isn't listed, then click Next.
Select Add a printer using a TCP/IP address or hostname, then click Next.
In the Hostname or IP address box, enter the printer IP address, then click Next.
Select the type of printer you are using, then click Next.
On the "Type a printer name window," do the following:

If you want to make this printer your default printer, check Set as the default printer.
Click Next.

Hello,

thank you for quick reply.

Because there were a lot of questions and tips in your reply, I will write my answers into the text of your post.

Did you make any changes to your printer?

 No, I have the problem from the begining.

Did you encounter the error message while scanning?

  No, the only error is shown in the scan to PC app. I have mentioned it in my post.

Try the steps recommended below.

On your keyboard, press Ctrl + Shift + Esc keys at the same time to open Task Manager. Here we will do some settings under both Process tab and Startup tab.

Find scanToPCActivationApp under Processes tab.
Then right-click on it to choose End task.

Find scanToPCActivationApp under Startup tab.
Then right-click on it to choose Disable.

Restart your PC.

 I have tried these solutions. Unfortunately without success.

Also, try assigning a static IP to your printer.

 I have assigned static IP adresses to all of devices (printer ans computers)

Refer this video article from HP support on assigning a static IP to your printer. Click Here

In the search type Devices and Printers. Open devices and printer.
Click Add Printer.
Select Add a network, wireless, or Bluetooth printer, then click Next.
Select The printer that I want isn't listed, then click Next.
Select Add a printer using a TCP/IP address or hostname, then click Next.
In the Hostname or IP address box, enter the printer IP address, then click Next.
Select the type of printer you are using, then click Next.
On the "Type a printer name window," do the following:
In the Printer name box, enter a name for your printer so you can identify it.
If you want to make this printer your default printer, check Set as the default printer.
Click Next.
On the "You've successfully added" window, do the following:
Click Print a test page.
When you have successfully printed a test page, click Finish.

Lastly, uninstall the printer software the root level on your PC and install the full feature printer software.

In Windows, search for and open Programs and Features. 
Select your HP printer. 
Select Uninstall. 
In Windows, search for and open Devices and Printers.

Open up the run command with the "Windows Key + R" key combo. 
Type printui.exe /s and click OK. 
Click on Drivers tab. 
Look for HP Printer driver. If you see it click on it and click remove at the bottom. 
Select OK. 
Select Apply and OK on the Print Server Properties windows. 
Close Devices and Printers. 

  I also reinstalled printer sw on each of computers but the problem didn't disappeared.

I have updated sw and printer firmware. I had no success with solving the problem.

After I tried all of these solutions, the scan to PC app is still randomly failing.

I'll be glad if you have some more ideas how would I solve it.

Thank you.

@Petr5192, Thanks for your detailed response and time.

You did a Marvellous job by trying the steps recommended previously.

As you mentioned the issue still persists after trying out the steps.

What application are you using to scan to PC?

If you are using HP easy scan try removing the app from your PC and install the HP smart app and try scanning again and check if the issue persists.

Refer this article to know more information about using the HP smart app on your PC. Click Here

Also, try updating the printer firmware and check if it helps.
