HP ENVY Photo 7855 All-in-One Printer

I have done all the steps in the other threads about his issue and it seems like none of them are working and that nobody has any options. 

So far I have done many power cycles

drivers

Diag tool can't find my printer

the printer says ready up until the point that I want to scan something then it becomes "Scanner not found"

 

It prints just fine. just can't scan.

Hi @nisthevision,

 

Welcome to HP Support Community.

 

Thank you for posting your query, I will be glad to help you.

 

I'm sorry to hear you're having trouble with your HP ENVY Photo 7855 All-In-One Printer. Since you've already tried power cycling, updating drivers, and using diagnostic tools without success, let's go through a few additional troubleshooting steps that may help resolve the scanner issue.

 

Step-by-Step Troubleshooting

Check Connection:

  • Ensure your printer is properly connected to your computer via USB or Wi-Fi.
  • If using Wi-Fi, make sure both the printer and computer are on the same network.

Update HP Software:

  • Visit the HP Customer Support - Software and Driver Downloads page.
  • Enter your printer model and download the latest drivers and full feature software.

Use HP Print and Scan Doctor:

  • Download and run the HP Print and Scan Doctor.
  • This tool can automatically diagnose and fix scanning issues.

Check Windows Services (for Windows users):

  • Press Win + R, type services.msc, and press Enter.
  • Locate the service named Windows Image Acquisition (WIA).
  • Ensure the service is running. If not, right-click and select Start. If it is running, right-click and select Restart.

Firewall and Antivirus Settings:

  • Temporarily disable any firewall or antivirus software to see if it is blocking the scanner function.
  • If the scanner works after disabling the firewall/antivirus, configure it to allow HP scanning software.

Reinstall the Printer:

  • Uninstall the printer from your computer.
  • Reinstall it using the latest drivers from the HP website.

Check for Scanner Lock:

  • Ensure the scanner lock switch is not engaged (if your model has one). This is usually a physical switch located under the scanner lid or on the underside of the scanner unit.

Use HP Smart App:

  • Download the HP Smart app for Windows, Mac, or mobile devices.
  • The app can help with scanning and might bypass the issue you’re encountering with the traditional scanning method.

Check for Firmware Updates:

  • Sometimes firmware updates can resolve hardware issues. Check the HP website for any firmware updates for your printer.

 

I hope this helps.

 

Take care and have a good day.
