Solved!

Initiating a Scan when the printer is in sleep mode

HP Recommended
HP OfficeJet Pro 7740
Microsoft Windows 7 (64-bit)

Whenever I try and scan a document after the printer has been "sleeping" I have to re-boot the printer every time to get it to work.  Using the scan to computer from the printer does not work as it states a computer is not connected to it.  When I open the program on the computer it's the same issue; scanner is not reachable or connected.  Once I reboot the printer, everything works again and that shouldn't be every time I need to scan.

 

Then every time I open the Scan and Printer Doctor it always crashes.

@executair101, Welcome to HP Support Community!

 

Assuming that the printer is connected wirelessly to the computer, I'd suggest you follow the steps below-

 

Restart the computer and the printer first.

 

Use HP Print and Scan Doctor

Download HP Print and Scan Doctor and run the program. It will automatically diagnose and fix any printer connectivity issues. 

For more information, go to https://support.hp.com/us-en/topic/printscandoctor

 

Assign manual IP to the printer

The steps on how to set a manual IP address can be found here.

For the DNS servers please use 8.8.8.8 for the Manual Preferred DNS Server and 8.8.4.4 for the Alternate DNS server. These are Google’s public DNS servers.

 

 

If the issue persists, try adding a TCP/IP port

  1. Print a Network Configuration Report from the Printer Settings or Wireless menu.
  2. Right-click your printer, select Printer Properties, click the Ports tab and then click Add Port.
  3. Select Standard TCP/IP Port, and then click New Port.
  4. Follow the instructions to add a new port using the information listed on the Network Configuration Report.
  5. Try scanning.

Hope this helps! Keep me posted.
