After exchanging modem/router I can´t scan on Wi-Fi anymore

[JTSato]

Hello there, I have been reading about this issue for 2 days in a roll tried lots of possibilities but I couldn´t find a way of scanning using Wi-Fi as I used to do it  (I can print using Wi-Fi properly and can copy too).

The error message is: Scanner Unreachable - Scanner communication cannot be established. Ensure your product is powered on, check the connection, and endure your network is functioning properly. If these conditions are correct, restart the product and try scanning again". I´ve tried all of these. The problem is not the Wi-Fi signal as the printer wi-fi icon is "full". 

Then I run the Print and Scan Doctor 5.1 and after waiting a lot the errors are on "Driver Check" and "HP Twain Scan". I restarted the computer as the software asks but nothing changed.

On HP Deskjet 3540 series software, when I try to check the Estimated Ink Levels appears the message "The computer is unable to establish two-way communication with the device".

I uninstalled the HP drivers, wiped the Registry and everything related to the printer, reinstalled DJ3540_188.exe (the latest driver for win7 64 bits) but no success. The Firewall was disabled but the error persists. The IP of the printer is right on my computer (192.168.0.14). I did the factory reset on the printer as well.

The modem/router provided by my ISP is the Technicolor TC7337. Before that, I used to have the Thomson modem (very simple modem/router) but used to work the wi-fi print and scan.

I don´t believe the issue is the network because it´s possible to print using the Wi-Fi. Probably is a driver issue but only uninstall and reinstall is not the solution.  

Oh.. and I installed a software called Paperscan 3 in order to check if the issue is the HP scan software, but the error came again.

I really don´t know what to do. Using the printer through USB is not a solution, unfortunately, as the computer and the printer are on different rooms (quite far for USB cable..)

Really thanks

Hi,

From Computer browse to C:\Program Files (x86)\HP and delete the Diagnostics folder.

Next, download and follow HP Print and Scan Doctor 5.0.4 below (a special version to resolve a printer offline condition):

http://ftp.hp.com/pub/printers/hppsdr/patches/HPPSdr.exe

Follow any suggested step, including restarting the computer (the tool will automatically re-launch a few moments after restarting) and check for any difference, once the tool completes, be sure to select to check scanning as well.

Please let me know how it goes,

Shlomi

Hi Greenturtle, really thanks for your reply. Unfortunately, it didn´t work out 😞  but I´m still trying to solve it. Really thanks.
