Thank you for posting on the HP Support Community.

Don't worry as I'll be glad to help, to provide an accurate resolution, I need a few more details:

• Are you getting any error messages or codes while scanning?
• What's the application you are trying to scan from? 

While you respond to that, let's reset the printer to recover from printer errors or failures.

• With the printer turned on, disconnect the power cord from the printer.
• Unplug the power cord from the power source.
• Wait 60 seconds.
• Reconnect the power cord to a wall outlet and to the printer.
  NOTE: HP recommends plugging the printer directly into a wall outlet.
• Turn on the printer to complete the reset.

Hope this helps! Keep me posted for further assistance.
