[brasilmichaele]

i have an issue with the Model of machine, Konica Minolta Bizhub 421/ 501. the machine quits printing. You can ping machine, web into the machine put will not print. Turn off machine and unplug for 5 to 10 minutes and turn it back on and it will print whatever is in the cue. I have replaced the OACB and IC207 and it still does the same. We have 3 of the machines doing the same thing. Help, anything to help would be greatly appreciated.

There is special firmware for this but before suggesting this do the following.
Unplug the machine from the network, go to a computer and ping the ip of the copier. Chances are you will get a response, this indicates that the ip is in use by something other than the copier and IT needs to fix it.

if you have the same problem in 3 machines, your problem are in the switch of the network, try with a crossover cable and make network with your pc, and send a ping, also you can make a little network with another switch and check, in many times the swith overheat and fail,

I'm sure it's a firmware issue. Flash it, if you can't flash it you'll need to pay someone to do them. If you are local I'll give you a sweet deal to do it.

I had this exact issue with a 421. I could hook my laptop up to the copier and print all day long. Once I hooked into the customers network (a large one), the machine would lock up within a few print jobs. Same thing I could still ping/access web browser and had to let sit off to get back.

I tried many things. Terrible solution but ours was to use the WSD driver or whatever they call it. I still believe it was some sort of reservation DHCP problem or something on the network. Will be interested to see if firmware does it. I could swear I did it, even replaced boards like you said.
