On my lanier ld024 wen i want to copy in color is asking me for key operation code i dont have the code does anyone know how to by pass or reset the code

Hi, you can turn off the key code management by going into User Tools. Press the User Tools/Counter button, then go to System Settings and then Admin Tools. There should be an option on the screen (you may have to scroll down) for key counter management -- turn this option off.
When you exit out of User Tools, you should be able to see the Copy screen just like you normally would, without having to enter a key code.
If the message on screen is asking you for a User Code rather than a key code or key counter, that option can also be disabled in User Tools. Go back into the Admin Tools and look for an option called User Authentication Management, or something similar, and either disable it completely or disable it for copying.
