Envy 7900 series error code: 024A493F/Hp Smart wont load

[Morticianoire]

So I am having trouble with printer today ( It was working fine yesterday)-the power cable is extremely loose and come out of socket at the hint of movement ( it has never ever been secure it comes loose very easily-awful design)

so today my printer wouldn't come on as the lead was very loose.

I have managed to secure power lead so I have power to the printer

I am now getting this error code on my printer: 024A493F. 

A quick search had someone with a different printer with same code requiring a factory reset

I can not use HP smart to do a  diagnostic on it as the app itself is just not loading-It is stuck with the swirl going round and round-I have uninstalled and reinstalled the app and it still wont load up

pretty poor experience using the app anyway in the past-but when I need it I cant use it

Anyone any ideas what to do?

at the point of getting rid and buying a completely different brand

@Morticianoire, Welcome to the HP Support Community!

Thanks for reaching out about your query regarding Envy 7900 series error code: 024A493F!  
We're thrilled to have the opportunity to assist you and provide a solution.  

It sounds like you're dealing with two frustrating issues:

1. The printer error code (024A493F)
2. HP Smart not loading

Here’s what you can try to fix them:

1. Fixing the Printer Error (024A493F)

Since you mentioned that someone with a different printer had to do a factory reset, it’s worth trying the same. To reset your HP Envy 7900 series:

Perform a Factory Reset

1. Turn off the printer and disconnect the power cable.
2. Wait for 60 seconds before plugging it back in.
3. While the printer is OFF, press and hold the Wi-Fi and Cancel buttons on the printer (or Back and OK buttons depending on the model).
4. While holding them, turn on the printer.
5. Release the buttons when you see the HP logo or reset message.
6. Follow the on-screen instructions to set up the printer again.

2. Fixing HP Smart Not Loading

Since you already tried reinstalling the app, here are additional steps:

Clear HP Smart App Data (Windows)

1. Press Windows + R, type %appdata%, and hit Enter.
2. Navigate to HP → HP Smart and delete the folder.
3. Restart your PC and try opening HP Smart again.

Try HP Print and Scan Doctor (Windows)

1. Download HP’s Print and Scan Doctor tool from here.
2. Open it and select your printer.
3. Run the diagnostic and fix any detected issues.

Alternative App Options

If HP Smart won’t work, try adding the printer manually:

1. Go to Windows Settings → Devices → Printers & Scanners.
2. Click Add a Printer and let Windows detect it.
3. Try printing a test page without using HP Smart.

Power Cable Issue

Since your power cable is extremely loose, consider:

• Using a different power cable (matching voltage & wattage).
• Using a different wall socket to check if the issue is with the outlet.
• Securing the cable with tape or a cable clip if possible.

Let me know if you need further help!

Take care, and have an amazing day!

@Morticianoire, Thank you for your response!

I understand how frustrating this can be, and I appreciate your efforts in getting your printer to work again. Let’s address the remaining issues one by one.

1. HP Smart Not Loading (Blank Screen & Non-Responsive App)

Since you've already uninstalled and reinstalled HP Smart, and cleared the %appdata% folder, let’s try the following advanced steps:

Run HP Smart as an Administrator:

• Right-click on the HP Smart app shortcut.
• Select Run as Administrator and check if it opens properly.

Check for Windows Updates:

• Go to Settings → Update & Security → Windows Update.
• Install any pending updates and restart your PC.

Reset the HP Smart App (Windows 10/11):

• Open Settings → Apps → Apps & Features.
• Scroll to HP Smart, click it, and select Advanced options.
• Click Reset, then restart your PC and try launching HP Smart again.

Try Using HP Smart on Another Device:

• If available, try logging into HP Smart on another computer, phone, or tablet to check if it’s an account-related issue.

Paper Detection Issue on HP Print & Scan Doctor

Since your printer is now printing but had trouble detecting paper, try these steps:

Check for Any Paper Jams or Misalignment:

• Remove all paper from the tray and reload it properly.
• Make sure the paper is aligned and not curled or stuck together.

Clean the Paper Feed Rollers:

• Turn off the printer and unplug it.
• Open the rear access door and clean the rollers with a lint-free cloth slightly dampened with distilled water.
• Let it dry before turning the printer back on.

Manually Set the Paper Size & Type in Printer Preferences:

• Open Control Panel → Devices and Printers.
• Right-click your HP Envy 7900 printer and select Printer Preferences.
• Under Paper/Quality, manually select the correct paper type and size.

If the issue persists, try printing directly from another application (like Microsoft Word or Adobe Reader) instead of HP Smart.

Let me know if you need further assistance. I’m happy to help!
