Question about Lexmark X4875 All-In-One InkJet Printer

Lexmar 4875 Flatbed Wireless printer not connecting to the networ

I have a Lexmark 4875 wireless printer, and i cannot connect it to my wireless network. On other computers, including my iphone and ipod touch, i can see "printer server 2129D5" listed in the available networks, and this only shows up when the printer is turned on. The wireless image/icon on the front of the printer itself is lit up in orange. I've downloaded Network Magic according to support page, but it doesn't seem to be working (I've been trying for about 2 hours now, so if the device was going to show up there, it would be there by now).

Using the USB cable that comes with the printer, i can print fine. Just not "wirelessly", which was the entire premise behind buying this exact model.

In the configuration menu on the printer, i do the following:
Setup > Network Setup > Wireless Menu
And it displays the following:

Press [checkmark] to select option
Network Name: "printer server 2129D5"
Wireless Signal Quality (This is an "option").

If i press the [checkmark] button, it just does a signal quality test that always sits at 0% "Unacceptable".

I'm using a Linksys WRT54G, and i have a PC, 5x Laptops, a Acer Netbook, an iPhone and an iPod Touch that can all connect to the wireless network without any problems, can get on the internet, etc.

However, nothing can see this printer, and i cannot change the network that it is attempting to join (the printer server 2129D5. I just want to join my home network "HomeNetwork").

Any help is appreciated.

I know you posted this in May, so have probably given up and bought a new printer by now, but I thought it worth mentioning that I had the same problem exactly (though without the same number of iphones and laptops!).
Buried away in some documentation on the driver CD, is the fact that the X4875 can't communicate with a secure wireless network that uses a TKIP algorithm - it can only handle AES. My router used TKIP out of the box, and I never thought to change is, especially as it's stronger than AES. However, changing it to AES solved the problem.
By the way, if you're using Vista, you may find that you have to run the install package in Windows XP compatibility mode, and then when the install is complete, manually change every .exe under c:\program files\lexmark\.. to run in XP compatibilty mode too. Works for me (Vista Business), but didn't work wirelessly at all before. Good luck,

How to connect to lexmark pro 905 wirelessly

First, make sure you connect the Lexmark to your wireless network. Select the tools (wrench icon) from the home screen. Scroll to Network Setup and enter your wireless permissions. If setup is complete and the printer successfully connects - the upper right wireless indicator will turn from orange to green. Then it's a matter of connecting your wireless device. If when setting up a new printer (or "Add Printer") you see the Lexmark in the list, then it's a simple point/click. However you might have to manually enter the IP address of the Lexmark on your device which you can find in the tools, Network Setup TC/IP menu.

The Lexmark X3650 printer is not a wireless printer. Lexmark wireless printers have the WiFi light logo/symbol that indicates it is capable of wireless connection.

Wifi connection

The Lexmark X2600 printer does not support wireless connectivity because it doesn't have a wireless network adapter. Another indication that the printer does not support wireless connection is that it doesn't have a wireless medallion symbol in front of the printer used to indicate wireless signal.

Lexmark 4875 finds bad CPU speed

I bought a Lexmark 4875 for mac. It bombs every application when you hit the "print" button. Downloading the fresh driver didn't help, and their support website doesn't address this issue at all.
