Lexmark S800 - Manual (Page 160)

4 Watch the Device Manager window while connecting a USB cable or another device to the USB port. The
window refreshes when Device Manager recognizes the USB connection.
• If there is activity on Device Manager but none of the previous solutions worked, then call Customer Support.
• If there is no activity on Device Manager, then there may be a problem with your computer and its USB
support. The computer must recognize the USB connection in order for installation to work.
Cannot print and there is a firewall on the computer
Third-party (non-Microsoft) firewalls can interfere with wireless printing. If the printer and computer are configured
correctly, and the wireless network is working, but the printer will not print wirelessly, then a firewall could be the
problem. If there is a firewall (other than the Windows firewall) on the computer, try one or more of the following:
• Update the firewall using the most recent update available from the manufacturer. Refer to the documentation
that came with your firewall for instructions on how to do this.
• If programs request firewall access when you install the printer or try to print, make sure you allow those programs
to run.
• Temporarily disable the firewall and install the wireless printer on the computer. Re-enable the firewall when you
have completed the wireless installation.
Wi-Fi indicator is green but the printer does not print (Windows
only)
Note: Make sure the Wi-Fi indicator displays only. If the Wi-Fi indicator is green but shows limited connection,
then this means the printer is not successfully connected to your wireless network.
If you have completed the configuration for wireless printing and all of the settings appear to be correct, but the
printer does not print, then try one or more of the following:
A
LLOW THE WIRELESS INSTALLATION TO COMPLETE
Do not attempt to print, remove the installation software CD, or detach the installation cable until you see the
Wireless Setup Successful screen.
E

1 Click , or click Start and then click Run.
2 In the Start Search or Run box, type control printers.
3 Press Enter, or click OK.
