4.6 Connecting to a peripheral unit
You can connect a peripheral unit to the printer using a modular plug. The
following describes how to install the ferrite core and make the actual
connection. See “Modular plug” on page 31 for details about the type of
modular plug that is required. Note that this printer does not come with a
modular plug or wire, so it is up to you to obtain one that suits your needs.
Important!
Make sure that the printer is turned off and unplugged from the AC outlet and
that the computer is turned off before making connections.

Affix the smaller ferrite core onto the modular wire as shown in the
illustration below.
