To everybody who cannot seem to get scanning working wirelessly this is
the method to make it work. First of all a little networking
information i suggest the way you set up your network is as follows :-
1)all computers on your network need to be set to auto configure as
2)in your router configuration browse to lan ip setup or similar where
u can reserve ip addresses for local devices using ur mac address i have
4 devices on my network at the present time all using ethernet as i
currently have no wireless devices except for this x4650 printer. my
config is :-
computer 1 ip reserved ip address 192.168.0.100
computer 2 ip reserved ip address 192.168.0.101
Xbox Media Center ip reserved ip address 192.168.0.102
Xbox 360 ip reserved ip address 192.168.0.103
lexmark ip reserved address 192.168.0.104
Make sure router is set to be used as a DHCP Server.
optional (but useful for security purposes) edit the starting and
ending adresses of the dhcp server to allow only the specified amount of
devices you will have on your network this prevent any other devices
such as laptops connecting to your network unless another address is
added to the DHCP server. This configuration is what is known as Mac
address filtering and is superior to standard DHCP or static
configurations. The reason why is the devices connected to the router
will think it is setup for DHCP however since the addresses were
reserved based on a devices mac address it will always recieve that ip
address this is useful when networks are expanded or modified over time.
Now the wireless side treat the printer just the same as any other
device connected to your router give the printer its own reserved ip
address you can find the printer MAC address on the back of the
Go into wireless settings on your router the way i have my wireless
setup is as follows :-
1) Disable Broadcast of name (SSID) (this means any wireless devices
will not be able to detect the router when scanning however wireless is
still enabled it just needs manual configuration.)
2)Enable preferred security method (personally i dont use it as MAC
address filtering renders WPA or WEP obsolete as no other devices can
connect unless specified in DHCP server. this also helps wireless speeds
tremendously as there is no encrytion overhead which takes up the
3) On my particular router Netgear dg834n go into wireless station
access list. then add your X4650 printer into the trusted wireless
stations and make sure access control is on. this is where WPA and WEP
become obsolete becuase if you have this option enabled unless the
wireless devices MAC address has been added to the trusted list it will
be denied access to the router.
4) enable UPNP on your router if it isnt already. UPNP can now be used
without having headaches for ports not being opened properly as all
devices are setup as a sort of Hybrid/Static configuration this makes
Applications like uTorrent work 100% without any configuration.
Right sorry for the long post but it is nesessary to have a correctly
configured router before tackling this as i also do not wish to repeat
myself in a later post. got to lexmark and get the latest drivers for
some reason i chose the larger driver first time the one that is
aproximately 80MB and i could not get the printer to print wirelessly it
said it was configured but printing test documents did not work. So i
uninstalled then choose the driver which is listed under color
configuration that is aproximately 45MB this one worked first time.
install and if you can print wirelessly you will be able to scan also
it is not nessessary to add a scanner in control panel for this
printer. the steps taken to scan successfully are as follows.
1) make sure you can print wirelessly first as this is the main
function of the printer and if that is not working then scanning will
2) make sure lxdxmon.exe is running make a shortcut to it and name it
wireless scanner or similar if u wish add it as a startup
application.(by default after installing this driver this application
will be set to startup automatically however i chose to remove it and
just start it when it is nessesary.
3)go to your x4650 printer make sure it is not in idle mode press the
4)Use the navigation buttons to select network press ok
5)your computer name should display if everything is setup correctly as
per the instructions double check that lxdxmon.exe is running in your
taskbar by the clock it is called Lexmark Fast pics.
6)click ok on the printer when you see your computer name it should
then say downloading application list at this point you should check
your computer to make sure windows firewall isnt blocking the incoming
connection from the scanner it will only occur once just allow the
exception and it will never appear again.
7) The LCD Screen should then say downloading application list and
after a few seconds will show the default list of applications (only
one at a time however the first on the screen is Internet Expl. use the
left-right navigation controls to choose a different application then
choose dpi settings and the default size of your scanned image from a
list of prest sizes eg A4 A5 B5 etc.
then press start and it will start scanning once finished it will open
the application of choice i defaulted to Paint and it saves the scanned
image in pictures folder. To add different application right click
lexmark fast pics and go to manage application list.
