Remove the label from the top of the used Deskjet 3740 inkjet cartridge that you want to refill. Under the label, you uncover five predrilled holes on the cartridge.

Fill the syringe from the refill kit with ink by placing the tip of the syringe in the bottle of ink and pulling back on the plunger. Approximately 15cc of ink should be enough to refill the cartridge.

Place the tip of the syringe into any of the exposed holes on the Deskjet 3740 inkjet cartridge and depress the plunger. Press slowly to prevent air pockets from entering the cartridge and ink from spilling out the other holes.

Continue to fill the cartridge until ink appears around the tip of the plunger. This indicates that the cartridge is completely full.

Place the label back on the cartridge if it is still sticky. Since the cartridge goes into the Deskjet 3740 printer with the holes facing up, it won't hurt anything if you cannot put the label back on.

Tips & Warnings
Refill the inkjet cartridge of your Deskjet 3740 printer as soon as the ink starts to show signs of running low, such as streaks or light text when printing. If a cartridge with low ink is allowed to sit for too long, the ink dries on the sides of the cartridge and you cannot use it again.
