Cant Reset F248 Error On Kyocera FS6525

[tecchie]

I have a customer with a Kyocera FS6525 with a F248 error. After researching the error I realize a firmware upgrade is necessary. The problem Im having is rebooting the copier doesn't reset the code. It will warm up and come to ready only to return with the error a few seconds after. Ive tried unplugging network cable and restarting and when it does come to ready quickly checking the print queue shows no print job at all to kill. No print job in the customers computer either. Rebooted computer to make sure their was no phantom print job somewhere and unplugged overnight. Still comes back. Tried to upgrade firmware even with the error coming up but firmware upgrade stalls when error comes up. Cant get into service mode either.


Is their a way to reset machine to reset error so I can upgrade firmware. Thanks in advance. Fairly new machine. Hope I don't have to replace controller and explain that to customer...

Disconnect the network cable. Then restart.

Any time I have seen this error it has been caused by corrupt data being send to the printer. Unplug the network cable and restart. See if code reappears. Cancel all print job, clear queues etc.

Few threads on this already, this one is a good a place to start with a few good tips.

Re: Cant Reset F248 Error On Kyocera FS6525

so if the network cable is left unplugged...completely off the ethernet LAN...and MFP restarted.. the code reappears? ?

i had this issue this week... (no code when off the network, plugged in.. 2 min later, the code hits)
after clearing all PCs and server.. it turned out to be coming from an XprintServer.. its that 3rd party wireless device that enables IOS devices to print.. it needed rebooting....so it was corrupt data coming somewhere from an Ipad or Mac or phone!

That's the weird thing. This is what I've done. Disconnect network cable and left unplugged. Unplugged machine. Plugged back in and restart. No jobs showing at all in machine queue but yet code returns shortly after machine comes to ready. It happened after customer sent over pdf file so it seems like corrupt data somewhere in machine but can't clear it in any way.

Go to system menu/counter key and select maintenance/adjustment then service setting then select memory diagnostics, press start, turn off machine, wait 10 seconds turn back on. This will see if you have a defective memory device, that is preventing a reset of an fcode.

You could also run sim 21 to initialize memory, but you might have to reinstall ip address info etc.

Cant get that far. Jumps back into the F248 a few seconds after warm up.

Do you have a fax option installed. if so, try removing the card and boot the machine. IF its comes ready then update f/w and reinstall fax card.

If fact remove any other option that the mcahine may have and update firmware if the machine comes ready.

Re: Cant Reset F248 Error On Kyocera FS6525

No fax option and if I try to update firmware it starts but I then get a cntrl error when code comes back.

Not sure how you are doing the f/w upgrade. But use usb stick with network cable unplug. If you are still getting the message this method, then try replacing the memory dimm

Emergency-UPDATE
If the device is accidentally switched off and upgrading was incomplete, upgrade becomes impossible from a
USB flash device.
In that case, retry upgrading after recovering the software by following the procedure below.
Preparation
The CF memory card must be formatted in FAT or FAT32 in advance.
Extract the main firmware to download from the file.
Rename the file which was extracted from the archive. [DL_CTRL.2MW] to [KM_EMRG.2MW]
Copy the all extracted files to the root of the CF memory.
Procedure
1. Turn the main power switch off.
2. Install the CF memory card which contains
the firmware onto the main PWB.
3. Turn the main power switch on.
4. Rewriting of the PWB software will start
for restoration.
The memory and attention LEDs will be
blinking.
5. Only the Memory LED will be blinking
when rewriting is successful.
* : Only the Attention LED will be blinking
when rewriting is failed.
6. Turn the main power switch off.
7. Wait for several seconds and then
remove the CF memory from the main
PWB.
8. Extract the firmware to download from
the archive and copy to the root of the
USB flash device.
NOTE: Deletes the "ES_SKIP.on" file
When it is contained directly under the
USB memory.
Figure 1-6-2
9. Insert the USB flash device in which the
firmware was copied into the slot on the
machine.
10. Perform steps 3 to 8 on the previous
page.
11. Turn the main power switch on.
12. Perform maintenance item U000 (Print
a maintenance report) to check that the
version of ROM U109 has been
upgraded.

Find the computer that's sending the print job and delete from queue. I always see this code when customers are printing from a website using internet explorer.

I agree with the above. But he said the code is popping up even with the nic cable uplugged and the machine print que has no jobs. Also cannot upgrade firmware.
Therefore i posted the emergency upgrade method that i found in the sm.


One more thought came to memory. Open side door and leave open. power up machine and go to service mode and do u21.

let us know.
