HPSmart scan fails when printer asleep

[WJPasNoddy]

Whenever I try to scan using the HPSmart app if printer is asleep, I have to turn off power and turn back on before scan will start. I have no problem printer to same unit when it is asleep.

Welcome to the HP Forums 🙂

I would like to take a moment and thank you for using this forum, it is a great place to find answers.

As I understand, you're unable to scan if printer is in sleep mode, 

No worries, as I'll be glad to help you, that said, I'll need a few more details to dissect your concern & provide an accurate solution:

Does your printer respond to print command in sleep mode?

When was the last time it worked fine?

Were there any hardware/software changes made?
How is your PC and printer connected?

While you respond to that, let's perform these steps: 

Update Firmware: Click here

Uninstall and reinstall HP Smart app

Let me know how this goes,

Cheers!

In response:

1. Print commands are responded to in sleep mode.

2. Never worked since install

3. SmartScan and diagnostics have updated all drivers, firmware 

4. Wifi connection only between PC and printer.

@WJPasNoddy,

I read the post. Thanks for the quick reply. It is awesome to have you back and our excellent efforts and troubleshooting are amply appreciated.

As @Flower_Bud is out for the day, I am responding on her behalf.

Please try these steps:

• Run all Windows updates completely.
• Uninstall and reinstall the latest version  HP Smar App by following directions from this link: https://support.hp.com/in-en/document/c04675142 (HP Printers - Using the HP Smart App (Windows 10) It gives steps to download, install and use the app with relevant FAQs.
• Also, assign a manual IP address to the printer if it is connected via a router by following steps from this YouTube video link: https://www.youtube.com/watch?v=SCnYyq80V9g

Good luck and keep me posted about the developments. If this helps, please mark this as “Accepted Solution” as it will help several others with the same issue and give the post a Kudos for my efforts to help. Thank you and have a great week ahead. 🙂

Tried uninstalling all HP sw, then re-installing. 

Same error occurred: error message said to restart printer and try again. This is same behavior as before. Restart printer does work, but it has to be done every time I want to scan. Very annoying.

Had to directly update the printer, not go through PC. Is good. Thanks.
