Turning a DC240 into a 250

[TribalBen]

I was talking with another tech locally about the differences between the hardware of the 240 and the 250. He, being more knowledgeable about the topic told me that it was just a little chip and a couple settings in the NVM.

Does anyone on here know what it would take to turn our 240 into a 250, or even 260 to get the increased print speeds?

Nothing urgent about this post, just a curiosity that I have not been able to forget about.

Can't change to 260, but you can convert to 250 exactly like he said. One thing is ..some nvm values on Xerox equipment are password protected, meaning you can't change them without having a secret password.

milo: curuoisity again . i have not been able to change some nvm's from pws but neither has a password window popped up.

what kinda nvm's are protected?

[Milo Wilson]

I know the NVM that changes speed is protected. I haven't checked any others though.

240 and 250 are from the same family, imperia I the 242 252 and 260 are Imperia II and have a totally different controller.

Concerning the change from 240 to 250 is possible bt you need to obtain NVM values from a DC250 first.

Kind regards,

Isn't there an actual single piece of hardware in there as well that is different which confirms which machine it is?

[artphil]

I wonder, they almost look the same...

And the part are also the same as far as I can see...

Is it the EEP ROM?

In the edocs, it says if you are replacing the ESS PCB, then you need to take the old parts from the one being replaced and put them on the new one.

Remove the following items from the old ESS PWB and re-install them on the new ESS PWB:

EEP ROM

DRAM (J330)

DRAM (J331)

DRAM (reverse of J337)

ROM (J332)

NVM (J334)

MAC Address ROM (U2402)

(Op. Font (J333))

(Op. DRAM (J338))

Re-install parts in reverse order of the removal procedure
