Lexmark X646 Network Connection Problem

Re: Lexmark X646 Network Connection Problem

I have seen this a few times on the X646 where it either doesn't boot or locks up as soon as it boots. Try this:

Turn it off, disconnect the ethernet cable and/or the fax line, turn on and make a test copy.

If it works make sure to delete any print jobs in the queue at your computer before pluging the ethernet cable back in. If it still doesn't work you probably need to replace the NIC card. It's pretty common for an electrical storm to kill the NIC card on any printer.

Re: Lexmark X646 Network Connection Problem

Not familiar with the Lexmark machines, but saw your post.

1. Do your IP Address settings on the Lexmark match the IP Address range with the workstations. It is possible that the Router or IP Address Server is issuing IP Addresses of a different range, after the power outage.

2. Can you attempt to ping the Gateway from the Lexmark control panel? This may not be an option, but is available on late model Sharps.

3. I am sure you have already checked this, but look for a light on the NIC Card on the Lexmark. If off, check the cable and for a possible bad port on their network switch. I see bad ports on switches rather frequently in our area of Virginia. Especially, after electrical and ice storms.

It could well be that Chameleon is right about the NIC, but it might be worth a shot just to check the above.

I wish you well!

I will check this machine physically on monday, he said that have more than one machine with
the same problem.
Is the NIC card integrated to the main controler pcb?
like in lex t620 the net port is integratef in the main board.
I saw the part # 43x2722 for main comtroler in x646 and the comm net port is in it.

Thanks, I will check all your suggestions.
Any other comments will be appreciated.

Re: Lexmark X646 Network Connection Problem

If the machines were set to DHCP and the network got fried, most likely the IP address has changed. As mentioned above, try to ping the unit. If not, reset the NIC card. If that fails, there is a yellow jumper on the main board. Power the unit down, move the jumper over one pin, and reboot. You could also try a cross over cable and a laptop to hook into it directly.

I try to reset the NVRam holding 6,7 and 8 and turn it on. But it gave me Service 900.00 "Rip Software". The machine stop printing by net after a electric failure. The ligths of the ports are blinking both. I print configurations and test pages without problems. Also my customer can't acess the machine from computers by the machine web page.

Any comment will be appreciated.

Re: Lexmark X646 Network Connection Problem

On the print configuration list, what is the IP Address, Gateway, and Subnet showing? It would be nice to see if you can contact the copier's webpage and/or print using a cross-overcable and your laptop. You will need to statically assign an IP Address on your laptop to match the range listed in the Lexmark to successfully contact the copier.

Let me know how this goes.

Re: Lexmark X646 Network Connection Problem

If you can print test pages, the issue is most likely coming from the network. There are a few things to try for the 900.00 error:
-Make sure the print queue is empty.
-Remove the network cable and reboot with the cable unplugged
-If it has options (fax, second tray) disconnect them and reboot
-Under Setup Menu, Print Menu, make sure NPA Mode is set to AUTO and the PS and PCL Smartswitches are set to ON

IP: 10.0.195.80
Netmask: 255.255.255.0
Gateway: 10.0.195.1

Then the system ad change the Gateway to 10.0.195.8

And nothing happens.

I didn't know that I can connect the machine directly to net port.
Or you mean connect the machine directly by USB com?

I was looking about error 900.00 and mention update firmware but 9 of 10 machine fix was by change the main board or sys board for this machines.

Hi, first thanks for your valuable time.
All setting was correct, all option was disconnected, when I try NVRam reset holding 6,7,8 and turn it on, it returns with 900.00 error with blue screen, no NVRam init was performed by the machine. I read about firmware update or 9 of 10 machine was repaired changing the sys board.

Your opinion will be appreciated.

I really appreciate your comment.

I do this:

Disconnect from net, it print a test page and do all functions without trouble.
I try to perform NVRam reset with 6,7,8 in power on, and error 900.00 "Rip software" appears on screen. No NVRam init was performed.
I read about firmware update or replace the main sys board.

I perform several Lexmark NVResets but in T6XX models and X3XX and the machines respond.

Note: No error is diplayed during boot or other machine operartion, all seems normal until I try to Init NVRam.

Any comments will be appreciated.

Re: Lexmark X646 Network Connection Problem

Mojorolla is on the same track as I am concerning your network, but also has specific knowledge pertaining to the Lexmark. I would follow his suggestions as opposed to mine because of his knowledge.

For a future point of reference concerning network troubleshooting in general you can purchase a Crossover Ethernet Cable or make one. This cable connects Ethernet ports directly between any printer and your laptop. You can also use any standard Ethernet Cable and purchase a Crossover Adapter, which simply plugs into either end of the standard cable. In almost all cases, you want to statically assign an IP Address for printers that are outside the DHCP range of the router or Server.

You have supplied the following information:

IP: 10.0.195.80
Netmask: 255.255.255.0
Gateway: 10.0.195.1

Then the system ad change the Gateway to 10.0.195.8

If the above IP address was obtained from the DHCP option, this IP address may change over time, especially when the copier is tuned off/on. If it is statically set, the address should never change. This is much the same as not wanting your street address to continually change, you want it to stay consistent. For your current situation, you could set your laptop's IP Address for 10.0.195.5

This fourth number of the IP Address can be any number between 1 and 254, with the exception of 80, which is currently being used by the printer. Once the laptop has a static number set in this range with the Cross-Over Cable between the two devices, you should be able to print to the device and view the webpage while isolating the printer from the entire network.

Again, this is really for future information.

I really appreciate your valuable comment, the repair contract wasn't awarded to us.
I didn't repair the machine but I will keep this valuable information in my records.

I like Lexmark printers and Multinationals, I have a some Lex T620 printers and Lex E232 rented to my customers, It works very nice.

Have a nice day.
