Refilling Procedures



Color Cartridge for HP DJ5550, P100, 7150 and 7350 Printers.

1. The fill holes are located on the top of the cartridge under the label.


2. Put the needle provided on the syringe and fill with 6ml/cc of the correct color ink.

3. Hold the cartridge with the blue top facing you. Insert the needle into the fill hole of the color to be refilled. (see diagram above, from left to right with the label facing you the colors are yellow, blue and red on the top.) You can also insert a clean toothpick in the fill holes to determine the correct color.

4. Push the needle into the cartridge about 1/4 inch. While watching the print head slowly inject the correct color ink into the cartridge . At the first sign of ink coming from the print head stop filling that color and draw back on the syringe "plunger" approximately 1/8 inch.

IMPORTANT: Do not reseal the filling holes if you do the cartridge will not work properly.

5. Place the cartridge back in the printer.
