8400N optional features, duplex not working

[CherylO-Xerox]

Hi Richard,

I apologize for the broken link.  The upgrade of the machine to duplex is a two step process.  The memory must be upgraded and the configuration card has to be installed.  Please take a look at this solution for information.  I was unable to find the part number you referenced.  If this does not help please consider contacting support.

Unfortunately when I went to the link you provided, I got,

The page you requested cannot be displayed.

The SIM card installed in the printer has the following part number printed on it, 156-8834-01.

• Is this the proper SIM card to convert the printer from SIMPLEX to DUPLEX capability?
• In addition to the SIM card, what other parts are required for 8400N to 8400DP conversion?

I have installed the most recent driver on my Windows 7 system and properly configured it so I can choose 2-Sided Print, under the 2-Sided Printing menu in the Print Dialog.

The printers management webpage does not show Automatic two-sided printing with a check mark beside it. I had searched all over the internet and was under the belieif that the above SIM card, specifically the quoted part number enabled Automatic two-sided printing.

So, my question is, how do I determine whether or not the printer has been properly upgraded to perform duplex?

Hi Richard,

Thank you for using the Support Forum. Please take a look at this information on pritning duplex on the 8400N. If this does not help please consider contacting your support centre for further assistance.

I recently purchased an Xerox 8400N. It does not show the Automatic two-sided printing nor 525 sheet feeder as being installed, the check marks are absent.

I looked at the SIM card, and the part number seems to indicate the printer is set up for duplex, and, there is a 525 sheet feeder that works which is mounted on the bottom of the printer.

I suspect the previous owner bought a SIM card thinking that that was all it took to do duplex. I suspect that there is more to the duplex upgrade.

What should I look for physically on this printer to confirm thta it does or does not have the duplex upgrade?
