Lexmark S415 User Manual

If you encountered problems while installing, or if your printer does not appear in the printers folder or
as a printer option when sending a print job, then try uninstalling and reinstalling the software.

Before you reinstall the software, check the troubleshooting checklist, and then try one or more of the
following:

Wait one minute for the printer and computer to reestablish the connection. This can sometimes
refresh network connections and resolve connectivity issues.

When you are connected to another network through a VPN connection, you will not be able to access
the printer over your wireless network. End your VPN session, and then try printing again.

Select printer features are not available when Demo Mode is turned on.

From the printer control panel, navigate to:

 > Setup > 

O K

 > Demo Mode >

If your access point is using WEP security, then the WEP key should be:

Exactly 10 or 26 hexadecimal characters. Hexadecimal characters are A–F, a–f, and 0–9.

Exactly 5 or 13 ASCII characters. ASCII characters are letters, numbers, and symbols found on a
keyboard. ASCII characters in a WEP key are case

‑sensitive.

If your access point is using WPA or WPA2 security, then the WPA/WPA2 preshared key/passphrase
should be:

Exactly 64 hexadecimal characters. Hexadecimal characters are A–F, a–f, and 0–9.

From 8 to 63 ASCII characters. ASCII characters are letters, numbers, and symbols found on a
keyboard. ASCII characters in a WPA passphrase are case

‑sensitive.

Note: If you do not know this information, then see the documentation that came with the access
point, or contact your system support person.

Wireless broadband boxes in Europe, the Middle East, and Africa such as Livebox, AliceBox, N9UF Box,
Freebox, or Club Internet may require you to press an association/registration button when adding the
printer to your wireless network.

If you are using one of these boxes and need more information, then see the documentation that came
with your box, or contact your internet service provider (ISP).

There may be temporary interference from electronic devices such as microwave ovens or other
appliances, cordless phones, baby monitors, and security system cameras. Make sure your access point
is not positioned too closely to these devices.

The range of your wireless network depends on many factors, including the abilities of your access
point and network adapters. If you are having trouble printing, then try placing the computer and
printer no more than 100 feet apart.

Print a network setup page and check the signal quality. If the signal quality is listed as good or excellent,
then another factor is causing the problem.

If you are using MAC (Media Access Control) address filtering to limit access to your wireless
network, then you must add the printer MAC address to the list of addresses allowed to connect
to the access point.

If you set the access point to issue a limited number of IP addresses, then you must change this so
that the printer can be added.

Note: If you do not know how to make these changes, then see the documentation that came with
the access point, or contact the person who set up your wireless network.

See if you have access to the Internet by opening your Web browser and accessing any site.

If there are other computers or resources on your wireless network, then check to see if you can
access them from your computer.

If the printer is not on the same wireless network as the computer, then you will not be able to print
wirelessly. The SSID of the printer must match the SSID of the computer, if the computer is already
connected to the wireless network.

Obtain the SSID of the network that the computer is connected to.

Type the IP address of your access point into the address field of your Web browser.
