To extract these files run the optengn.exe file or double click it.

1.  Go to a DOS prompt.

2.  Change directory to the one containing the Engine Code files.

3.  Turn the printer on and make sure it is connected and in the Ready state. 
NOTE: Make sure you are using a high quality (IEEE 1284) 6 foot cable or Lexmark's 10 foot cable. 

4.  Type the following command (depending on which OPTRA you are updating):

		For the OPTRA R or L, the command line should read:
			Copy P4394-12.PJL /B LPTx

		For the OPTRA Rx,Lx,Lxi,R+,Rt+,Rn+,Lx+,Lxn+ or Lxi+, the command line should read:
			Copy P4394-16.PJL /B LPTx 

	NOTE: The  in the above commands LPTx represents the port to which you are copying; this port can be physical, redirected, or captured.

5.  The printer display panel should read Programming Engine Code. 
	NOTE: Do not power off the printer or touch any menus during this operation. If the printer does not return to Ready after 15 minutes, it is safe to turn the printer off and back on.

6.  When the printer returns to the Ready state, print the menu settings page. To print the menu settings page: 

		1 Press the button next to Menus.
		2 If you do not see Test Menus, press More until you find it. Now select Test Menus.
		3 Press the More button until you find Print Menus. Select Print Menus.

7.  The appropriate updated engine code should be displayed in the bottom right corner of the menu settings page.  Make sure the engine code on this printer has been updated - that is, an engine code level of 43.94 should be displayed. 


Using a TCP/IP or network connection:
You can also attempt this upgrade using a TCP/IP or network connection, provided you know the TCP/IP address of the printer. Note: Lexmark recommend upgrading the engine code using a direct parallel connection whenever possible. To perform the engine code upgrade using a TCP/IP or network connection: 

1.   Go to Start, Programs, MSDos Prompt. 

2.   Change to the directory that contains the engine code file.

3.   Type ftp and then press ENTER twice. 
	For example: ftp 157.184.29.127

4.  Type bin and press ENTER. 

5.  Type put and press ENTER. 
	For example: put P4394-12.PJL

	For the OPTRA R or L, the command line should read:   put P4394-12.PJL
	For the OPTRA Rx,Lx,Lxi,R+,Rt+,Rn+,Lx+,Lxn+ or Lxi+, the command line should read:    put P4394-16.PJL

The printer should now read Upgrading Engine Code.
