I have a SP55 Simplex Datacard printer that has the capability to be upgraded to duplex and I have install the program on a windows 7 64 bit system. The test card comes out perfect but when I do a 2 sided card and I installed the upgrade for the printer version 10 to have it to be able to print with a Win7 64bit operating system. I keep getting the error "The duplex module is not installed or detected. (DM-00765) I go into the setup for the printer and there is a ! in a yellow triangle beside the duplex setting. Help me please. what do I do? Also I am using the key for IB51010299 if that helps

If you re-formatted the PC, then you likely wiped out the instance of the correct driver for your printer. Windows typically does not come with a driver for any but the most popular ID-card printers. When you reconnected the EdiSecure printer, it likely associated it with what it believed to be the closest driver to the one required (but missing) - the Datacard driver. To correct:

1. Through the Windows Control Panel, then Device and Printers (or Printers and Faxes if WinXP), find the instance of your printer (set up as Datacard); right-click on it; select "Remove Device" (or "Delete", if WinXP);
2. When complete, disconnect the printer from the PC;
3. Through Windows Control Panel => Programs (Add/Remove Programs if WinXP), find and un-install any instances you find of Datacard programs or drivers;
4. Reboot your PC;
5. From either the printer's install disk, or the manufacturer's website, download and install the correct driver for your Windows OS. If prompted to re-boot, do so. NOTE - do not connect the printer to the PC until you are either prompted to do so by the driver-installation program, or the installation completes normally and without errors.
6. Connect the printer to the PC. Give Windows time to recognize the device, associate the new/correct driver, and tell you it's ready for use.
7. Check in the Windows print center (Control-Panel=>Devices & Printers (or Printers & Faxes) to verify that it is now recognized as an EdiSecure printer.

The printer is not "ready" The printer needs to be ready with a green lite for the install to complete. You can download a quick start guide that will get the printer installed at the link

The printer needs to be serviced, The Monochrome issue could be related to a problum with the RFID chip in the take up wheal of the ribbon, but the duplex offset can only be adjusted by an authorized service provider using a special password and diagnostic tool.

Hello,
The printer does not know the the model of the ribbon installed and thinks it is a monochrome (single color) Print ribbon. You can verify this in the Driver toolbox under the supply tab, or in the advanced printing options.
The Datacard SP series printers use an RFID Radio freq. tag in the take up spool end of the ribbon. This identify s the ribbon model and supply use settings for the printer.
Make sure you have the most recent driver and firmware from Datacard, There is a firmware Update Available to help reading "weak" RFID tag's
Next try removing the RFID tag from another (old) ribbon and see if it that fixes the problem)
Aside from that you:
May have a counterfeit (non-Datacard) ribbon
A bad RFID tag
Someone removed your RFID tag
You need a firmware update (weak RFID tag)
A bad RFID reviver in the printer, which is a fairly cheap repair.
Basically try a new print ribbon if that does not correct the issue, have the printer serviced.

To convert you would have to change system board, and buy new print head, it would be cheaper to trade in for discount on new printer.
