250f networking

[rileycp]

i've been trying to set up a di250f to a network or about a month. i've gone through one bad controller and got agood replacement form the supplier. I had to reset the network card and was told i had to change it to a static ip which i have done but it still is donong the same thing. what it is doing is after about an hour or so it looses connection and can't get it back.
any help would be great thanks!!!

I can think of two things that will cause this problem. First, the controller is bad. Two, there is another device that is using the same IP address as the copier.

Try pinging for another device with the copier disconnected from the network. I can't count the number of times I've had strange behavior from the copier only to find another device using the same IP addy.

ok i checked the print controller and its ok i have also try'd pinging for another device with same address and there isn't one. Any other suggestions???

Might be worth a try.
Try changing the speed of the nic card from auto to 100.

Network

If you do not have a duplicate IP address on the network, and you have a known good NIC, then it may be:

- bad network cable
- bad wall jack (drop)
- wrong config (10 Mbps/half duplex OR 100 Mbps/full duplex)
- bad port on the switch or hub

Change the cable, then (if no joy) use another drop. You should be able to ping the machine from any computer on the same network segment at the very least.

In a windows environment, use the following command (on a computer on the same segment) to test for reliability of the connection:

ping 000.000.000.000 -t
(substitute the copier IP address for the zeroes)

This will ping the machine continuously until you press <CTL> C to break.

You can use the following command in a windows environment (on a computer on the same segment), to find the network config info. for that network:

ipconfig /all

GL.

Good call. I've had all of these show up as a problem at one time or another.

The switches tend to show up more often than I'd like. I've had a number of cases where a managed switch was set improperly. Sometimes a port just plain goes bad. Other times, it seems that the port gets messed up due to bad cables or noise -somewhere- in the network. If the problem goes away after reseting the switch then comes back later, suspect noise or heat related type problem with the switch.

i am still having problems. how do you change the speed???

I don't see where you can change the speed with this model.

Have you tried attaching a prepared (network configuration compatible with copier settings) laptop to the copier to test printing while/after the copier has started acting up? I try to do everything I can to verify the problem is really in the copier/controller or not. I've wasted FAR TOO MUCH TIME working on customer network problems.

Have you tried resetting the card to factory settings via the hardware jumpers?

Sorry but i don't know this model but usually you can change it in the web browser. Sometimes you can't see the option, but maybe try something like this might work.

(IP) xxx.xxx.xxx.xxx/speed
in web browser

Somebody else might know if this jogs their memory enough.

What do you mean by attaching a prepared (network configuration compatible with copier settings) laptop to the copier to test printing while/after the copier has started acting up?

Yes i have reset to factory.

Install the drivers for the Di250 on the laptop. Use the IP address of the copier in question for the port address. Be sure you use 'standard TCP/IP' and the Minolta Network Card for the network card type. Make sure you are using the proper data type, default is lpr, use print as the queue name ("print" in lowercase works in every case I've used it, don't remember the official Minolta preferred name).

Set up the laptop IP address (not the same as copier) and subnet to be compatible with the settings of the copier. After the copier has started printing garbage on the customer's network, remove copier from customer network, connect your laptop to the copier using a crossover cable, send a print job to the copier from the laptop.


If the laptop can print ok, then your work is probably done.

Web interface ?

If you enter the machine's IP address in Internet Explorer or other web viewer, can you get access to a graphical administration screen ?

If you can, you can check and adjust most network settings that way.

i have done that and after about an hour it loses the ip and wont get it back

I think this only works in the Konica RIPs, don't think there is a way to do it with the generic Minolta network cards.

I have been wrong before though...............

so i had a recent problem where a customer could not print to there di250 and it would ping once in awhile i could log into the controller everything. first thing i did was replace the controller same problem. next try to replace the main power supply and it fixed it. swaped one from another machine. once i brought back the other controller to my office to trouble shoot it i got codes and all sorts of crap. it worth a shot but i would suggest looking for a use one before you buy a new one
