heh, I appreciate the mention, not gonna bitch at ya. Just don't like irrelevence from others who go off subject without getting to the point. I know what you mean and kuby as well. I don't believe it's the NIC as I have never seen an onboard NIC die. Which is why I mentioned another possibility.

Ok so further info was requested.
3 different cables were used. My laptop WAS directly connected to the copier. I used the laptop NIC as well as a USB NIC to my laptop to check if there was something funky with the laptop as well. Laptop was rebooted 3 times. Copier was also restarted (as in the original post). The laptop is a field test device so I wipe it monthly (Dell Latitude, Core i7, 32GB RAM, 1TB NVMe). I know I added more than was asked, just covering all bases. All contacts were cleaned and retested. Did I say 2? heh, I only tried 2. The customer site has a dozen or so copiers, a few of them have this problem. They were acquired years ago at the same time. The copier dealer stated that they were new at the time and received regular maintenance BUT the HDD's were never replaced.
So I will change my approach here for a sec. I keep mentioning the HDD's and I explained why. No one has touched on that. So I'll ask this, how do you know when the HDD's in the copiers are dying? Are there multiple symptoms or usually just a limited few?

I have zero experience with either one of these models, and of all of the 52 and 53 series machines we had, never had a hard drive fail. Not sure how difficult their setup is, but there's always the option to use U021 to reset the machine, and then MANUALLY input settings, and see what happens.Comment

Just a thought, had one that a Iphone was stealing the IP and causing issues with the copier/printer printing or going offline. After restarting the copier/printer it would work for a while and then would start having issues again, you could not ping or print until restarting or the person turned the iphone off. The copier needs to be using a Static IP and is that IP reserved in the DHCP table as to not give it out. That is what we did to resolve the issue. Just something to check.Comment

Usually you will see C0640 codes in the device logsComment

Have you considered telling the customer to eat a bag of.... wait wait, sorry, no, don't do that. BUT, weren't these built in 2013? ick, get new ones.Comment

Ah facts. There they are. Obviously you know a lot more about networking than I do.
Now, just for a moment, listen to my advice: MFP network cards don't fail intermittently. They work or they don't. For years I've had IT techs tell me to change network cards, and it has literally never been the cause. Honestly I don't care if you take my advice. I came on to maybe save you some time. Please feel free to go down this rabbit hole. And yes, this post does define you.
If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Well, this is probably the most frustrating bunch of replies I’ve ever read on a forum. SensiNyC, you detailed the issue and what you’ve done better than any copier tech normally would. The loss of connectivity with a direct connection to your laptop is the key step that seems to have been missed by commenters above. Assuming you’ve used your own known good network cable, it points directly to the machines NIC. You say the tech performed a reset, either a u21 or via command centre. This will factory default the Nic which is a step I would have also done. My only concern is these machines are quite old now, likely 10 to 12 years. I have not had any of this model in the field myself for maybe 5 years so have no experience on what the electronics in the NiC will do at this age. What sort of environment are the machines in? Near the sea? Corrosive chemicals, anything that might compromise the pin connection of the NIC? These machines have a fan that blows cooling air directly onto the main board and I’ve seen many fail due to corrosion caused by their proximity to the to the sea. I’ve never seen one with your exact symptoms.
So, the question is, what can you do?
First thing I’d do as a dealer would be to try and upgrade the client. “Puppy dog” a new machine for them to try for a week. They like the machine as it has no issues and they buy it. Problem solved.
or
Try and source a IB-50 which is an optional gigabit network card or an IB-51, an optional wireless card and test the connectivity with those.
or
Have the copier tech company replace the main board as the NIC is a part of that.
Good luck. Alan.
PS. Re the HDDS. On the high speed machines of this era, they doubled up two 160gb Hard drives to give 320gb storage. Later models had a single 320gb HDD. I doubt these are anything to do with your issue. They are just storage and play no part in the copier re connection or firmware. You may even find the copier will function without them minus a function or two like job storage. On later models, HDDs were an option.Last edited by Ropariva; 2 days ago.Comment

If you are so convinced that it's the HDD in multiple separate devices, why not just get them changed/swapped to prove a point to the customer/dealer?Comment

And I agreed with that over and over. I was not suggesting the NIC failed. I did actually point out a few times that since MFC's (as you put it) are actual computers running a variant of the Unix/BSD OS, that it may be a HDD failing which does cause intermittent NIC problems. But if no one here has ever seen that and the copier company that called me in also has not seen that, I will not push that possibility as ihatefinishers13 has pointed out, the machine is 12 years old.Comment
