View of HP 51625A Type Cartridge with Top Removed

1. The filler holes of the cartridge are located under the green top. The green top must be removed before refilling by carefully levering off with a thin metal blade, such as a penknife. Alternatively lay the cartridge on its side, hold down firmly, and strike the green top with a blunt instrument to break its seal.

2. Assemble the syringe and filling needle and fill with the correct colour ink.

3. Insert the filling needle into the filler hole of the colour to be refilled, (see diagram above) and push downwards until the filling needle reaches the centre of the cartridge.
   Note: The cartridge contains sponge and a slight resistance may be felt.

4. Slowly inject up to 10mL of ink until the sponge is saturated.
   Important: Clean the syringe with water, and dry before refilling another color.

5. After refilling the top can be refitted and secured with adhesive tape.
