Solved: Re: Scanner Unreachable - HP Support Community

have a proble with a scanner/printer error:

Scanner communication cannot be established. Ensure your product is powered on, check the connection, and ensure your networkis functioning properly. If these conditions are correct, restart the product and try scanning again.

If you installed this printer by IP address, then you might need to update the UP address. Use the Update IP Address item in the Start menue entry for this printer.

If you are running firewall software, it may be blocking scan communication. Please visit .... to congigure your firewall.

Has anyone seen this before?

What did you do to resolve this?

Thank you.

Hello DMarple2

Glad to hear you were able to update the IP address of your printer. To assign the printer a static IP follow the steps below:

Step five: Assign your HP product a static IP address

If your computer regularly loses communication with your wireless HP product, it can help to give the HP product a static IP address. This address will not change over time and your computer might have an easier time recognizing the HP product after long periods of printer inactivity.

Follow these steps to assign a static IP address to your HP product.

Refer to the network configuration page or the wireless network test report that you printed in Step one, and locate the IP address of the HP product.
Open a new Internet browser window, and type the IP address of the HP product in the browser's address bar, and then press Enter . A web page displays, showing the internal settings of the HP product.
Click the Networking tab, click the Wireless tab, and then click the IPv4 tab (your menu path might be slightly different, depending on your HP product model. A new settings page displays.
On the page that displays, make the following changes:
1. Set a Manual IP : Your wireless router automatically sets an IP address within a specific range (called the DHCP range). If you know what the DHCP range is, set an IP address in which the last set of numbers is outside that range, but no higher than 254. Keep the first three sets of numbers the same. If you do not know the DHCP range, select a fairly high IP address, like 250 (again, for the last set of numbers). To learn about your router's DHCP range, contact your Internet Service Provider (ISP) or wireless router manufacturer.
2. Set subnet address : Use 255.255.255.0, unless you know that it is different, in which case you should use that number.
3. Set the gateway address and the first DNS : Enter your router's IP (can be found on the network configuration page or the wireless network test report).
  NOTE:Leave the second DNS field blank.
Click Apply . The screen will not refresh. If you changed the HP product's IP address from what you typed into your Internet browser, you will have to type in the new IP address to access the HP product. If you did not change the HP product's IP address, wait 30 seconds after clicking Apply, and then click the Refresh button in your browser.
Print another network configuration page (or wireless network test report) from the control panel on your HP product to verify that the product's IP address is what you assigned.
Turn off the wireless router. If the wireless router does not have a power button, disconnect the power cord on the router to turn it off.
Press the Power button ( ) on the HP product to turn it off.
Turn the wireless router back on. If the wireless router does not have a power button, reconnect the power cord to the router to turn it on.
Press the Power button ( ) on the HP product to turn it on again.
If you changed your HP product's IP address in step 4, then there might be an additional step needed, depending on your printer model (this step applies only to Windows users):
1. Locate the HP folder:
  Windows XP
  Click Start ( ), click All Programs , click HP , click the folder for your HP product, and then look for an item called Update IP address .
  
  Windows Vista or Windows 7
  Click the Windows icon ( ), click All Programs , click HP , click the folder for your HP product, and then look for an item called Update IP address .
2. If the Update IP Address entry is not present, then no additional steps are required.
3. If the Update IP Address is present, click it and enter the new IP address that you entered in step 4.
If your HP product is connected to the wireless network, and you are able to print and scan , there is no need to continue troubleshooting.
If your HP product is connected to the wireless network, but you are still not able to print or scan , continue to the next step.

This error was due to an IP conflict where another device had the same ip address.

Hello everyone

The Original Poster and the second poster stated they ran the HP Diagnostic Utility and it resolved their problem. You can find the HP Print and Scan Doctor at the link below. If you need further help though let me know what happens.

My problem is that when I run the print/scan doctor, it shows my printer, but it shows the wrong IP address. When I go to the printer and go to setup and check the IP address, it is 192.168.2.2. My laptop thinks the IP address is 192.168.2.5.

How do I tell my laptop to go out and re-verify the printer's IP address? Since I am (by default) using dynamica IP addresses, every time I reboot, power printer up and down, I may get a different IP address (the last digit changes.)

So, how do I tell my laptop/hp software on my laptop to check the printer's IP address?
