Once properly installed, the Sharp Black/Red Ink Roller operates automatically as part of your compatible calculator or printer. The ink roller provides the necessary ink for printing characters in black and red, depending on the device's functionality.
No direct user interaction with the ink roller is required during normal operation. The device will utilize the ink as needed for its printing functions.
5. Maintenance and Storage
5.1 Storage
- Store unused ink rollers in their original sealed packaging to maintain freshness and prevent drying.
- Keep ink rollers in a cool, dry place, away from direct sunlight and extreme temperatures.
- Avoid storing near chemicals or solvents that could damage the ink or roller material.
5.2 Disposal
When an ink roller is depleted, remove it from your device and dispose of it according to local regulations for electronic waste or general office supplies. Some recycling programs may accept used ink rollers.
6. Troubleshooting
If you encounter issues related to printing quality after installing a new ink roller, consider the following:
6.1 Faded or Incomplete Print
- Check Ink Roller Installation: Ensure the ink roller is correctly seated in its compartment. Remove and re-insert it to confirm proper alignment.
- Verify Ink Roller Freshness: If the ink roller has been stored for an extended period or in unfavorable conditions, it might be dry. Replace it with a new, freshly sealed roller.
- Device Settings: Consult your device's manual to ensure there are no specific settings affecting print density or color selection.
6.2 Ink Roller Does Not Fit
- Verify Compatibility: Double-check that your device's model number is listed in the compatibility section of this manual or on the product packaging. Incorrect model numbers are the most common cause of fit issues.
- Inspect for Damage: Ensure the ink roller itself is not damaged or deformed, which could prevent proper installation.
If problems persist, refer to your device's original user manual or contact the device manufacturer for further assistance.
