true techs know this. they do this to keep end users from fucking up their machines

Bit late now to give advice ...........

you are not a true user if you don't fuck up the machine for the tech to fix

I also had this case.
I'm glad I can tell you.
The bizhub C308 or bizhub 287 models
You cannot use firmware with SenDisk.
You can use third-party 8G or 16G to work with firmware.

I'm using 2 & 4GB USB Pen drives without any issues.

I have to be honest. In my four-year career, no one has ever given me this advice.

I have never disconnected the network cable.

Some manufacturers advice you to do this on the training course, but I don't bother or simply forget, apparently it can cause an issue if the client sends a print job while updating.

Nothing in the service manual or knowledge base suggests this on any KM SMs I have looked through. ..Must be an urban legend..You should never say Bloody Mary 3 times out loud while upgrading firmware..lol

If I'm in a hurry, I never upgrade.
Printers sense my stress and freeze hahaha

I've never seen anything like this mentioned for KM, nor have I ever had an issue updating with the network cable plugged in. I do know that when I worked on Ricoh/Savin lines, it was a requirement, and they pushed it hard in training. If anything came over that network cable during the update, it would cause you some major headaches that you really didn't want to experience.

Yes, maybe i'm thinking of a Ricoh course, been on so many different manufacturers over the years.

However I do pull the LAN if working on a Bizhub in a busy office, it stops the users printing when i'm trying to access CE mode!
