Installation & Usage Tips

1. Power off your typewriter before removing the old ribbon cartridge to avoid mishandling.
2. Remove the old ribbon by lifting the cartridge latch or sliding forward, depending on your model.
3. Insert the new ribbon, aligning the spools and feeding the ribbon under the guide bar, following directional arrows on the cartridge.
4. Recheck alignment and threading, then close the latch and power on the machine.
5. Perform a test line, ensuring consistent ink pickup and clean correction operation (if using lift-off tape).
6. Consider replacing both the ribbon and the corresponding correction tape simultaneously for consistent print quality and performance.

Compatibility Notes

• Always verify your machine uses Group “COB” style cartridges before ordering.
• Some typewriters may have older or rare variants; consult your manual or service label to confirm part numbers.
• If your device uses film ribbons for different models (such as Selectric or non-Wheelwriter lines), this cartridge may not fit—check model number and compatible parts list

Built for reliability, this ribbon is ideal whether you’re restoring a classic Wheelwriter or maintaining a typewriter in active use. Enjoy crisp black output and smooth correction capabilities.
