Answer

Manual for Refilling HP 910 and 910XL Cartridges

Materials Needed

• Empty HP 910 or 910XL cartridge
• A syringe with a needle
• Refill ink (color-specific)
• Paper towels
• Gloves (optional)
• Silicone sealant (e.g., BCH Protection 10K+ for sealing the cartridge)

Preparing Your Work Area

1. You can cover your workspace with paper towels to catch any spills.
2. Please ensure you maintain good ventilation, as ink fumes can be intense.
3. Wear gloves to avoid staining your hands.

Refilling the Cartridge

Step 1: Locate the Ink Chambers

• Could you remove the cartridge label to expose the ink-fill holes?
• HP 910 cartridges typically have an ink sponge chamber and an air vent. You inject the ink into the sponge chamber.

Step 2: Prepare the Ink

• You can use a syringe to draw the appropriate colour of ink.
• Fill the syringe with 4-6 ml of ink (depending on the cartridge size).

Step 3: Refill the Cartridge

• Could you insert the syringe needle into the sponge chamber via the fill hole?
• Slowly inject the ink to prevent air bubbles.
• Stop injecting once the ink oozes from the sponge's top.

Step 4: Seal the Cartridge

• Apply a small amount of silicone sealant to cover the refill hole.
• Allow the sealant to set for at least 5 minutes before handling further.

Post-Refill Instructions

Step 1: Reinstall the Cartridge

• Insert the refilled cartridge into its designated slot in the printer.
• Close the printer lid and wait for the printer to recognize the cartridge.

Step 2: Print a Test Page

• On the printer’s LED screen, navigate to:
  Setup → Printer Maintenance → Print Quality Report
• Print a test page to check ink flow and alignment.

Step 3: Perform a Cleaning Cycle (if necessary)

• If print quality is subpar, run the printer’s cleaning routine:
  Setup → Printer Maintenance → Clean Printhead
• Avoid running multiple consecutive cleaning cycles, as this wastes ink.

Troubleshooting Common Issues

1. Ink Not Flowing:
   
   • Ensure the cartridge is correctly seated.
   • Check the sponge chamber for clogs and clean it if necessary.
2. Error Messages:
   
   • Confirm that “Chip Info” is turned off if the cartridge is not recognised.
   • Clean the cartridge chip gently with a dry cloth to ensure proper contact.
3. Leaks or Overflow:
   
   • Check that the sealant is secure and excess ink is removed.
   • Avoid overfilling the cartridge.

Maintenance Tips

• Store refill ink in a cool, dry place to ensure longevity.
• Refill cartridges immediately after they run out to prevent the sponge from drying out.
• Regularly clean your printer’s printhead to maintain optimal performance.
