5. Operating Instructions
Once the Graphtec IJ-91001MBK ink cartridge is correctly installed, your printer is ready to produce high-quality prints. Follow your printer's standard operating procedures for printing documents or images.
- Print Settings: For optimal results with matte black ink, ensure your printer's software settings are configured for the appropriate media type and print quality.

6. Maintenance
Proper maintenance ensures consistent print quality and extends the life of your ink cartridge and printer.
- Storage: Store unused ink cartridges in their original sealed packaging in a cool, dry place, away from direct sunlight and extreme temperatures.
