I am an IT guy not a copier guy. We have had our bizhub C650 for a few years. Just recently it started "crashing". When I say crash I can no longer print to it, I can no longer get into the web management interface with IE or firefox.
I can ping it and I can telnet to port 80 and get a connection. I have verified that no other device has the same IP we are using a static IP for the C650 and if I unplug the network cable I can no longer ping or telnet to port 80. As you would expect since I can ping it I can see the tx/rx lights on the network jack. Only solution I have found is to power cycle the C650 and it will run for a random number of days before it crashes again. I though it was a bad network cable or run screwing up the C650 and making it crash. So I swapped the cables, network drop and switch port with the canon copier right next to it. Same issue, C650 will randomly lock-up/crash, canon keeps running.
At this point I had the copier guy come out when it was in a locked up state so he could see it. He plugged his laptop into it. Could not get connected to it so he power cycled it. He said he found no errors. He did upgrade the firmware. He said the problem was my network or print server. I tried to get an explanation on how my network or print server could crash the copier. But he just told me there were no error codes and there was nothing wrong with the copier. My print server is running the latest PCL drivers. So when he left I set up my network monitoring software to ping and connect to the management HTTP interface every 5min and alert me when it failed. Well tonight, Friday night at 7pm it crashed again. I am 99% sure no one was in the office printing or scanning. I can ping the C650 and I can telnet to port 80. But I can not get the administrator web interface in IE or firefox. Nor can I print or mange the printer setting from my print server.
So now that I have it crashed is there anything I should check befor power cycling it? Should I go into some secret admin/tech page on the copier to look for error codes?
Thanks for any pointers as my copier vendor has left it up to me to resolve.
