Welcome to the HP Community --

True - "Dormant" sounds different from sleeping.

Assuming all the printer software is installed and is functional, it might be necessary to make sure the computer is awake and ready to receive the scan content.  The printer might not be able to wake the computer for you.

If the computer is logged in and should ready to receive input,

The printer is perhaps losing it's connection to your network.

Check the connection - Connect the printer to a manual IP / static address and a separate SSID named network at the band / frequency you want the printer to use.

What else?

Scan to Computer is part of the Full Feature Software.

The Scan to Computer Service might not be enabled or perhaps has balked or stopped (failed).

Open the Printer Assistant > Tab Scan > Manage Scan to Computer > Enable

1) Dual Band Network - Considerations

Reminders 

Some printers, particularly older models, only support 2.4GHz

Some printers support both 5GHz and 2.4GHz – but not at the same time

Regardless, if the printer won't work or cannot connect to your 5GHz frequency, try 2.4GHz.

If you are running a Dual Band Network,

 Check that the router is set up to broadcast all frequencies it supports.

Next,

If your router supports it,

 Create a separate SSID named network for each frequency (5GHz and 2.4GHz).

and

 Connect the printer to the SSID network on the frequency / band you want it to use.

In general,

• 2.4GHz is less fussy about obstacles and supports a longer distance (separation) between router and device (printer)
• 5GHz is faster

2) Printer Software

Printer - Full Feature Software - Install

If you have not done so, consider

• HP Full Feature Software / Full Driver printer software - supports printing and scanning from the web, printing in in other software and programs (for example, Word), and provides access to the full range of Printing Preferences / Shortcuts.  The full driver adds at least two shortcuts to the Desktop:  Printer Assistant and HP Scan.  If the printer model includes built-in Fax hardware, the software supports the setup and use of the Fax driver.  No Sign-in required.

If the full driver printer software is (already) installed but not working,

• Uninstall any printer software from Control Panel > icon view > Programs and Features
• Restart the computer and sign in.

Next,

• Check (for the Printer) in Devices and Printers  > If found, Right-Click Printer and Remove -- If any changes are made, that is, you remove anything, Restart the computer and sign in.I

Next,

• If using a printer USB cable between the printer and the computer, disconnect the cable before installing the printer software.

• Download and Save the Full Feature Software installation package or the Easy Start Software
