Konica Minolta C550i - boot issue 50%

[Kenny]

hi guys,

we replaced the CPU and now the machine is working, thank you all for your suggestions

Is there a way on the small printers (the one I'm thinking of Konica rebrands as a 4000i) to disable the wireless interface? We have users who push that wifi button and turn off their Ethernet interface on a weekly basis.

On Brother only way is to turn on Setting lock don't know if it will work on Konica rebadges.

We are Konica AND Brother dealers so tell me anything you need to know about Brother MFPs

Hey mate. Would you be able to tell me what brother machines are best for replacing Konica c3350i, C3351i?
Have nothing but issues with the Konica's and I keep hearing Brother is a good alternative.

The problem with color Brothers is only one but it's big. Price of original toners is deal breaker.

I am starting to like the Kyo color A4's.

Would not hurt to reload the boot program
put firmware stick in mahcine
go to firmware screen
before the firmware starts, hit machine type
enter 172938 (make sure machine type does not change)
Hit OK
bring you back to firmware screen
at bottom of page you will see BOOT

If you do the boot rom and the process does not finish and the display goes black with no lights, it is the CPUB.

Try the Kyo or as I know them the olivetti 3023 color A4. The brother color compatables dump toner. But does work ok.

Recent business class brother MFPs use wireless interface as option (e.g. MFC L9670/MFC L6910). As for older ones you can remove the WLAN pcb or mess with the country/model code I think. But better discuss this question at the brother sub forum though.

connect to the pc, remove the partitions and format in fat32, then install boot rom following service manual, after that install firmware, and finally, push recover data when it appears on display after rebooting after fw load

Thanks for the tiip - we tried that with an adapter on pc but weren't able to revive the nVME's for use in a KM i-series (they were fine for use as external memory or in computers though).
After installing the nvme the KM started creating partitions but finally did not accept it. We didn't follow the procedure to install a boot rom though, guess I might have to RTFM again^^
