Setup and Installation
This chip is designed to replace the existing chip on your printer's maintenance box. The exact procedure for removing and installing the maintenance box and its chip may vary slightly by printer model. Always refer to your printer's official user manual for specific instructions on accessing the maintenance box.
- Power Off Printer: Ensure your printer is turned off and unplugged from the power source before beginning.
- Locate Maintenance Box: Open the printer cover or access panel to locate the maintenance box. Its location is typically indicated in your printer's manual.
- Remove Maintenance Box: Carefully remove the maintenance box from the printer. Handle it with care to avoid spilling any waste ink.
- Remove Old Chip: The old chip is usually attached to the maintenance box with clips or adhesive. Gently detach the old chip, noting its orientation.
- Install New Chip: Align the new UP C9382 C12C938211 chip with the designated slot on the maintenance box. Ensure the gold contact points on the chip align correctly with the corresponding contacts on the maintenance box. Press firmly until it clicks into place or is securely attached.
- Reinstall Maintenance Box: Insert the maintenance box back into the printer until it is securely seated.
- Close Printer: Close any covers or access panels that were opened.
- Power On Printer: Plug in and power on your printer. The printer should now recognize the maintenance box as new or reset.
Operating Instructions
Once the new maintenance tank chip is correctly installed, the printer will automatically detect it. The chip functions by resetting the internal counter that tracks the waste ink level. Your printer should now indicate that the maintenance box is empty or has sufficient capacity, allowing you to continue printing without interruption due to a 'full maintenance box' error.
Maintenance
The UP C9382 C12C938211 maintenance tank chip is a single-use, disposable component. It does not require any maintenance itself. When the printer indicates that the maintenance box is full again, the chip will need to be replaced with a new one. It is recommended to replace the physical waste ink pads within the maintenance box or replace the entire maintenance box when replacing the chip to ensure proper waste ink absorption and prevent leaks.
Troubleshooting
- Printer does not recognize the new chip:
- Ensure the chip is correctly seated and its gold contacts are clean and making good contact with the maintenance box.
- Verify that the chip model (C9382 C12C938211) is compatible with your specific printer model.
- Try removing and reinserting the maintenance box and chip.
- Restart the printer.
- Error message persists after chip replacement:
- Consult your printer's official user manual for specific error codes and their resolutions.
- Ensure you have installed the correct chip for your printer's region, as some printer models may have regional variations.
User Tips
- Always confirm the compatibility of the chip with your exact printer model and region before purchase and installation. For example, a user inquired about compatibility for the Epson WF-C5810 in South America, highlighting the importance of regional verification.
- Handle the chip by its edges to avoid touching the gold contact points, as oils from your skin can interfere with connectivity.
- Consider replacing the waste ink pads inside the maintenance box or the entire maintenance box when replacing the chip to prevent potential leaks or overflow of waste ink.
