Dell Refill Instructions

J740

Black Cartridge

Empty cartridges should be refilled immediately.

Drill a hole in the top of the cartridge using the 1/16" thumb drill provided as shown in the picture.  (Do not remove the top.)

Fill the syringe with 25cc. of ink, insert the needle into the drilled hole and push down into the center of the cartridge. Slowly inject up to 25cc of black ink into the cartridge.

Set above a paper towel for half an hour as a drip precaution. Expect a few drips. Do not allow the cartridge to touch the paper towel at this point, since the towel will draw out the ink.

Replace the cartridge and run 1 - 3 cleaning cycles as per printer instructions.

Colour Cartridge

The filler holes of the cartridge are located under the top. Remove the top before refilling by carefully prying it off with pocket knife.

When you take off the color cartridge cap will notice that the sponge is white.  Fill the individual colors until the color just begins to show in the white sponge.

Assemble the needle and syringe, place the needle into the ink inlet hole and push until slight resistance is felt. Remove the needle from the cartridge, this will allow you to see a small amount of colour on the needle.

If the colours are different from those on the instructions supplied, then fill the chambers as per the appropriate colour sequence in your cartridge.

Fill the syringe with ink and insert the filling needle into the filler hole of the color to be refilled.

Slowly inject up to 8ml. of ink until the sponge is saturated.

After refilling the top can be put back on with scotch tape.

Replace the cartridge and run 1 - 3 cleaning cycles as per printer instructions.
