The printer is capable of using C.S.I (Coated Side In) and C.S.O (Coated Side Out) ribbons in the following configurations:


½” Core Ribbons

Ribbon Core Width: 4.3 inches (110mm)
Ribbon Width: 1.0 – 4.3 inches (25 – 110mm); Centered on core

1″ Core Ribbons (with Ribbon Core Adapters, see section 2.4.1.)

Ribbon Core Width: 1.0 – 4.3 inches (25 – 110mm); Centered on Ribbon Core Adapters
Ribbon Width: 1.0 – 4.3 inches (25 – 110mm); Centered on core

Load ribbon as follows:

  1. Determine the type of ribbon (C.S.I or C.S.O) you are using.

  1. Push out the Supply Hub and load the Supply Roll into the printer as shown. Depending on the size of the Supply Roll, the Media Bouncer may need to be pushed out of the way.
  2. Once the Supply Roll is loaded, slide the Ribbon Handler Latch downward to unlatch the Ribbon Handler Assembly.

  1. Push out the Take-up Hub and load an empty Ribbon Core into the printer as shown.

  1. Route the ribbon from the supply roll to the Ribbon Core, as shown below.
  2. If not already attached, affix the leader of the ribbon to the Ribbon Core using Tape. Rotate the Take-up Hub Wheel several times to secure the ribbon.

  1. Raise and latch the Ribbon Handler Assembly. Close the cover and press the button several times to advance the media (if the Fault Light is lit, see Section 3.7.)

Using the Ribbon Core Adapters

When using ribbons with a 1″ (25.4mm) I.D. core, a Core Adapter must be used.

      1. Slide the Ribbon Roll (with the leader positioned as shown above) onto a Core Adapter. Slide an empty Ribbon Core onto the remaining Core Adapter.

    1. If using a narrow ribbon, position the Ribbon Roll so that it is centered on the Core Adapter. The Core Adapters are marked in both inches and centimeters to aid in proper positioning.
