For HP Deskjet 3320, 3325, 3420 printers
1. The filler holes are located under the coloured top of the cartridge.
2. Peel label back on top of cartridge.
3. Assemble syringe and steel filling tube and fill with black ink
4. Insert the steel filling tube into the appropriate filling holes. (See diagram above) Push down into centre of the sponge.
IMPORTANT - Cartridge contains a sponge and a slight resistant may be felt.
5. SLOWLY Inject ink. When ink overflows from filling hole or starts to leak from print heads cartridge is full. Stop injecting immediately.
6. After refilling replace label back over hole and seal with adhesive tape.
7. Leave the cartridge to stand overnight on non-absorbent surface. This will ensure no leakage and give the ink time to fully saturate the sponge.
IMPORTANT – DO NOT LEAVE ON TISSUE.
8. Install cartridge and run a priming cycle.
PLEASE NOTE: The ink indicator level may need to be turned off. Check your HP instructions manual for details.
