Reprogramming the Security Key
The security key on the PSA3 controller board can be reprogrammed with a
Software Program Exchange (SPX) module. The SPX is an intelligent module
that plugs into the debug port on the back of the P8000. The SPX is used only
once; it automatically overwrites itself after successfully reprogramming a
security key. This allows the end user or a service technician to enable
features such as new emulations without having to remove covers and install
a new security key on the controller board.
The SPX is used at power-up only and is not left in the printer during normal
operation. Because it is a single-use disposable item the user is not required
to return it to the vendor or manufacturer.
How to Program the Security Key
1. Power off the printer.
2. On cabinet models, open the rear door. On pedestal models, refer to
Figure 27 to locate the debug port at the rear of the printer.
3. Insert the SPX into the debug port as shown.
