Hi KelliZ,
I understand you're having issues scanning from the front panel of the printer to the computer. I'm sorry to hear this, but once I gather a bit more information I'd be happy to help!
1. Which model of HP printer do you have?
2. Which version of Windows or Mac are you working with?
3. Are you able to initiate the scan from the software on the computer?
4. Were there any updates done to the PC, router or printer that you're aware of?
Once I have this information I should be able to assist you better!
