Removing the interface card from the printer
You'll need to remove the interface card from the printer to
change the self-test jumper setting. Follow these steps:
Turn off the power to the printer and the computer before you
remove the interface card. Make sure that the power cord for
your printer is unplugged.
Avoid touching the printer circuits or circuit board contacts, since
many of these components are sensitive to static electric charger
that may build up on your body.
1. Using a Phillips screwdriver, unscrew the two screws securin
the interface card (see Chapter 2 for a diagram).
2. Gently pull the card out of the compartment.
Changing the self-test jumper setting
The Interface Card for LocalTalk has three jumpers, one of which
is used for selecting the self-test function.
