Please share some one, architectural difference between xerox d125 and Nuvera 120EA models.
Hi Nadeem,Thank you for using the Xerox forum.
The main differences are speed and toner type.
I would suggest that you review the Xerox Support & Drivers site for complete answers to your question.You can enter the model in the center search box and then select support.
On the right column is a product specifications link (shown below)
The 2 models support pages are linked here D125 and 120EA
