    F248 ... interesting!

    Enduser has a Kyocera FS-C2526MFP, called Kyocera and talked with tech support. Tech support said: bad main board. They have a service contract so they call us with "Order us a main board ... ".

    I don't know about you, but I don't usually base my actions on a customers diagnosis. It usually does not end up being accurate, and they expect us to eat the part cost when they're wrong, or end up sitting on that part forever. Besides, I have some experience with F248 codes.

    The machine is Off upon arrival. I turn it On, and within a few minutes the F248 has popped up. Next I disconnect the network cable and power up: no code. Next I connect my laptop and ping, print, scan, and check the web interface: no code.

    The thing I've seen is non-print data being sent to the printer's IP address, especially on large networks. I'm sure there's a way to pin down exactly what sender's IP address, Mac address, and what type of data, but the simplest solution is to change the printer's IP. No need to track down the source if it's sending to an open IP. Plus there are only three endusers in this area. Simplest just to change the port.

    You'd think that tech support would have suggested the solution that was the simplest to test, most inexpensive, and needing no parts to fix. You'd think ... but I'll bet they like selling $1000 circuit boards too, necessary or not.

    Does anyone have any experience with tracking down the source of this non-print data? I'd imagine Wireshark would be suitable. The problem is, on a really large network a huge amount of data is gathered within a very short period of time. Can you tell Wireshark to watch just one IP address, or a narrow range? And what kind of data can be gathered? Sender IP or Mac address, Date/Time, Port#, Data type? More?

    =^..^=
    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.

    Up grade to higher versioN of Unit,or maybe upgrade the mEMory? I experience that codE,i did i initiallize all memORY,but i think there some data That cannot read by the machine,maybe kyocera upgrade there Bord

      I think in Wireshark you can apply a capture filter and select which kind of traffic you want to analyse, and it should be possible to monitor one single ip-adres or hostname. It's been a while since I played with Wireshark, but I think it's possible.

        Cool! The one time I played with Wireshark I ended up with pages and pages and pages of data. There was so much data it was impossible to sort the wheat from the chaff. =^..^=

          If you have the Filter Toolbar present in Wireshark, you can click on the Expression button and select the appropiate filter. Selecting the correct filter can be difficult, because there are so many of them. You can also design your own filter, but I really don't know how to do that.

          You have to apply some filter or else you end up with a huge amount of data. Just reloading the Copytechnet home page generates more than 300 lines of data.

            So your theory is that the 1.024 GB of standard memory are filling before a page has printed? There is a 1.024 GB memory upgrade, but i can't imagine a situation in which a single printed page filled 1GB of memory. =^..^=

              It doesn't have to be non-print data. I had a customer printing to their new Kyocera using software that had built in support for a range of HP printers.

              They wanted to use the Kyocera as their printer so they selected one of the available HP drivers and started getting CF248 codes.

              Their IT staff said it must be a bad network card.

              I explained that you can't just randomly select a print driver and we stopped using the Kyocera as the printer for that software. The codes went away.

              Printing from a wrong driver can cause these codes so I recommend that a new install get a new unused IP address rather than the address of an old printer.

                Funny you should mention that. At installation, when I assigned the original IP address the new Kyocera printed off some documents that had waiting in the queue for the last 5 years. Apparently someone is still sending with that driver.

                Thanks for the comments. =^..^=

                  For anyone that may be getting this code --

                  I got this code recently and it turned out to be that the customer's IT installed the KX XPS driver on their machine instead of the KX driver. I'm not sure why exactly as they got the newest version off the website but it would randomly code out and / or print 50 blank pages when it was a 2 page excel document. Installed KX driver on their PCs and all is well.

                      I've seen this a few times! It is some errant data or the machine just can't format it. (Usually printing from internet). I like the idea of changing ip address of machine but, a bit difficult in a large network. Upgrading firmware usually does not help, even tho a good idea.

                        print as bitmap minimizes occurance.


                        and tech support knows shit. got another enthusiastic IT for a client call tech support for another CF code, tech support says Motherboard.

                        we went, turns out its for the HDD.

                          Gotta love those ITs that blame network problems on the machine.. I had one that actually said "If I have two of the same machines and one is not working then it MUST be a machine problem" Turned out the "two users" that could not print where mapped to the wrong driver, and getting the IT to remap them to the server took an act of congress practically.

                            ^^Agree. Print as bitmap has done great for us. We've had problems in the past with PDF, Google docs, and printing from browsers. All threw an F248. We haven't had any call backs for F248s on machines we've set to this. Not to say that we won't. But, so far so good.

                              We have also experienced the f248's. We have had some luck with turning off unit, unplugging the network cable, turning on the unit, waiting for it to come to ready, go to job listings page on the screen, then re-plugging in network cable. Many times, just for an instant you can see the station ID flash before f248 pops. Latest firmware also created some relief it appears. Depending on size of the network and users to that MFP, we have had each end-user power down their workstation, reboot, (clearing their print jobs) then having each user re-sending their jobs in series. Culprit is always identified. If too large of a network, I could see that scientific technique being less effective.

                              Additionally, make sure the latest driver is installed.

                              Good luck and may all of that particular family of units find their way to the floor, from three feet above, by accident.
