Abstract
A device, such as a printer or copier, identifies the type of module being used. If the type of module requires the device to receive an unlock code, the device prompts for the unlock code (which can be a hash of the serial number of the device). Once the unlock code is received, the device can be used with modules of that type. If the unlock code is not received, the device does not operate with modules of that type.
