5 • Getting Started

Removing the Shipping Restraint

Important

Do not plug the printer into the power outlet until the following steps have been completed.

1. Remove any packing tape.

2. Reach into the top cover slot (1) and remove the access cover (2) by lifting it.

3. Remove the printhead shipping restraint. Keep the shipping restraint for future use.

4. Reinstall the access cover.

6 • Getting Started

Installing/Replacing the Ribbon

Cartridge

Use only genuine Oki Data ribbon cartridges.

When replacing a ribbon cartridge, make sure you have the correct replacement ribbon for your printer. The wrong ribbon will not print when installed in your printer.

Important

• Leave unused ribbon cartridges in their packaging until you are ready to install them.

• Careful! The ribbon ink can cause permanent stains.

• Ribbon ink on skin or clothing can usually be removed with soap and water.

1. Make sure the printer is turned off!

WARNING!

If the printer has been recently used, the printhead may be

HOT!

7 • Getting Started

2. Remove the access cover and center the printhead.

3. If you are replacing the ribbon cartridge, remove the used one:

Important

Do not remove the ribbon shield (1) from the new ribbon!

8 • Getting Started

4. Unpack the ribbon cartridge and install it on the printhead.

Note

If the ribbon won’t load easily, turn the take- up knob slightly until the x-shaped notch on the bottom of the ribbon cartridge aligns with the x-shaped insert on the ribbon plate.

5. Press gently on the ribbon cartridge until you feel it click into place.

9 • Getting Started

6. Turn the take-up knob (1) in the direction of the molded arrow to take up any ribbon slack.

7. Replace the access cover.

Installing the Platen Knob

Align the notch (1) with the pin on the platen shaft and push it firmly into place.

10 • Getting Started

Adjusting the Head Gap

The head gap is the distance between the printhead and the platen roller. When you use envelopes or multipart forms, you need to have a larger gap than when using plain paper. Use the recommended head gap to ensure the best print quality and easy paper feed

CAUTION!

Incorrect setting of the head gap can cause printhead damage or ribbon jams. To avoid these problems set the head gap for the type of media being used.

To adjust the head gap, move the colored lever (1) located to the left of the ribbon cartridge to the correct position for the type of media being used …

…as detailed in the following table:

Paper Type Lever Position

Single Sheets, up to 20 lb. (75 g/m

Forms, 2-part [maximum thickness 0.28 mm] 2 or 3

Forms, 3-part [maximum thickness 0.28 mm] 3

Forms, 4-part [maximum thickness 0.28 mm] 3

)
