4. Operating Instructions
Once installed, the Lexmark 1380999 Ribbon operates automatically with your compatible impact or dot matrix printer. The ribbon feeds through the print head as characters are struck, transferring ink to the paper.
4.1. Printing
Initiate print jobs from your computer or directly from the printer's control panel. The printer's print head will strike the ribbon against the paper, forming characters. Ensure paper is loaded correctly and the printer is online.
4.2. Correction Function
This ribbon is "correctable," meaning it includes a correction film. For typewriters or printers with correction capabilities, you can typically backspace over an error, and the correction film will lift the incorrect character from the paper. Refer to your specific printer or typewriter manual for detailed instructions on using the correction feature.
5. Maintenance
- Storage: Store unused ribbons in their original sealed packaging in a cool, dry place away from direct sunlight and extreme temperatures.
- Handling: Handle the ribbon cassette by its frame to avoid touching the inked ribbon, which can cause smudges or damage.
- Printer Cleaning: Regularly clean your printer's interior, especially around the print head area, to prevent ink buildup and ensure smooth ribbon operation. Consult your printer's manual for cleaning procedures.
- Ribbon Replacement: Replace the ribbon when print quality begins to fade or characters become inconsistent.
