Have a Sharp MX-M503n which appears to be losing network connection in a local school. When the problem occurs they can no longer print nor scan on the mfp. The network lights both light solid when this occurs and when trying to scan they get a 'Network out of service' message. We have reseated all connectors and rom/memory chips on mfp board and today had them switch network ports at the switch. Firmware has been updated to latest version. If switching ports on the switch doesn't work, any ideas?

Re: MX-M503n losing network connectivity?
Do you have a duplicate IP address out there somewhere? =^..^=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.

Re: MX-M503n losing network connectivity?
I don't believe so but won't be able to check until the issue arises again. Our tech was on site while the machine was working and stated the network lights were both solid even though it seemed to be working.Comment

Re: MX-M503n losing network connectivity?
Have you tried...?
-a packet capture (the only way to fly, in my humble opinion)
-pinging the NIC card (127.0.0.1)
-adjust soft switches for network speed (auto is default setting)
-inspecting the job log; there should be codes tied to failed scans
-set up a laptop to MFP network and test print and scan. Solid lights indicate data flooding the machine from the network.
You can test for a duplicate IP by unplugging the network cable and pinging the IP address. If you get a reply, another device also has that IP addy.
Failing to plan is planning to fail!!!Comment

Re: MX-M503n losing network connectivity?
Does any PC on the network have a bad CMOS battery ? If so that PC will logon to the network with an incorrect date-time. If using security certifcates these will software flag as out-of-date also,and can lock the software down, or dump that PC off the network. This happens more so on port 80 HTML, where certificates are download/auto-install more often Check also for roaming laptops personal printers with conflicting IP addresses.

Re: MX-M503n losing network connectivity?
Wouldn't print or scan again this morning. Error message when scanning was 'Network Interface is out of service...'. Was able to ping IP address of copier from computer successfully. Upon pulling network cable ping would fail. Pinged 127.0.0.1 from within copier settings successfully.
1) A packet capture is something their IT dept would have to do so will be after whatever it is we can do.
2) Hooking a laptop with crossover cable might be next step at this point.
3) Should try setting it all the way to 10/half duplex or find a middle ground and try it there first? (10/full)Comment

Re: MX-M503n losing network connectivity?
100MB/full duplex has resolved this problem for me. Any slower and your print jobs seem to take forever, and the web interface times out on you continually. =^..^=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.

Re: MX-M503n losing network connectivity?
I have tried changing link speed manually as well as xover cable to laptop. The activity light acts normal when connected to laptop. Changing link speed down to 100 or even 10 didn't seem to make a difference.
This has gotten weird now. There is more than 1 machine on the school's network with both the link and activity light on constant. One is an older AR-M455n so it's not just MX-M503n's. The AR-M455n is in the same building as the original problem machine. The AR-M455n doesn't seem to experience the same network connectivity loss however.
If they disconnect the network link to the other school buildings the activity light on the copiers act or operate normally. Is there a user or network size limit for the Sharp copiers to operate on?
Its also not just this one location. There is at least one other school building which has an MX-M503n where both lights are lit constantly. Will post when have more updated information.Comment

the only way you can try, direct plug the crossover lan cable from laptop to your mfp and try.
i got same problem with my mx-5001n, some computers/laptop using same ip address with mx-5001n.So ip address conflict and fail to print/scanComment

Re: MX-M503n losing network connectivity?
We have done direct connection. Activity light is normal when directly connected to laptop.Comment

If the above statement as I read it means that if they disconnect network to other buildings copier acts as normal. Then I would want their IT people to do packet capture with and without connection. Seems that the common factor is the rest of the network. If copier works with crossover cable or buildings disconnected your job is done. It would be a IT issue.Comment

Re: MX-M503n losing network connectivity?
I've seen this twice before (both times at the same school) with the exception that the data light would flash then the mfp would power down. Turned out to be a corrupt file somebody tried to print off the internet. I had the school IT guy clear the print queue, and the problem went away.Comment

Re: MX-M503n losing network connectivity?
Just wanted to give an update:
Spoke with Sharp technical support. They mentioned disabling of WSD port/service in the copier. This along with leaving the copier on overnight appears to have alleviated the network connectivity loss. Not sure if it has fixed the constant activity light though.Comment

Re: MX-M503n losing network connectivity?
I just went through an identical situation with Sharp copiers at my location. This was dealing with MX-5001, MX-C402SC, MX-3110, MX-C401, and a few others. I didn't get much help from Sharp, as they tried updating firmware, etc. I didn't get much help with our IT department, as the Network Group sniffed the network ports and the Systems Group made sure no updates had processed on the print server. Luckily, I found your post above and took a leap of faith in trying it on the affected copiers. I had about 12 total copiers experiencing the issue. I have since gone back and disabled the WSD on all of our copier fleet and have yet to have a single instance of unexplained network loss. We are three years into our contract with Sharp, and the WSD service has been active FROM DAY ONE!!! Our IT department has no insight as to any changes that would have caused this to start happening randomly after three years. I was wondering if your IT department shared any insight as to any changes they may have made that would have caused your issues. With 200+ copiers at our location, I really wanted answers as to a possible cause, but have received none to this point.
Thanks in advance!

Re: MX-M503n losing network connectivity?
WSD(windows services for devices, something like that) is a microsoft service , it is plug and play for network devices ,similar to plug and play for usb. It is available in Win 7(may have been vista also) but I first noticed when I connected my win 8.1 tablet to our network. Our mx2610n popped up as a printer when I hadn't installed the print driver yet. The issue is the ms driver for the sharp mfp's is not in windows by default, you have to do an add printer then windows update to get the ms drivers. setup the wsd printer and it does work. the wsd port on sharp mfps appears to be on by default , am not sure about other manufacturers. don't know why the mfp goes offline/no network, unless the port number that wsd uses is being blocked or conflict between standard network printer and wsd printer on pc/server. I have both running and haven't had any issues yet.Comment
