1.This cartridge requires minor drilling with the provided drill bit in order to expose the sponge inside the cartridge located beneath the plastic top. Refer to the image below or the *Drill Spot* section above for the drill location. NOTE: The drill bit included with this kit is SHARP and should be used with CAUTION. (Hold bit on its blunt side and apply slight pressure while twisting it in BOTH a clockwise and counterclockwise motion (back and forward). It may take a few minutes to break through the plastic). For safety reasons DO NOT apply heavy pressure to the drill bit while twisting. It does not require much pressure to drill through the soft plastic of the cartridge. Once the drill bit creates a small hole on the top of the cartridge, REMOVE the bit and do not drill further into the cartridge. Drilling the sponge will permently damage the cartridge. (Store drill bit and kit in a SAFE location and out of the REACH OF CHILDREN when the refill process is completed)

*This drill bit does not include a handle or grip since it is an actual high speed drill bit and not the brittle drill tools sold by other companies. These are designed to drill through much harder material than the cartridge’s plastic top*

2. Fill the syringe with the proper amount of ink. (See Ink Volume section above for the proper fill amount.) You may need to fill the syringe multiple times depending on the amount of ink required. (Standard syringe sizes come in 3cc or 5cc) -> 3cc = 3ml / 5cc = 5ml

3. Insert the needle into the hole as shown in the picture reference (Right) and SLOWLY inject the ink into the cartridge. (Note: It is important to INSERT the needle no more than 1 INCH into the cartridge -> Inserting the needle completely into the cartridge or wiggling it during the refill process will permanently damage the cartridge). Some cartridges may not be able to accept the stated fill amount as the sponge may still contain some ink residue. If the ink begins to spill out from the top of the cartridge pull the syringe back 1/2 ml and STOP.

4. Fill the syringe with clean water and drain to prepare for the next color.

5. Repeat steps 2-4 for the remaining colors.

6. It is normal for the printhead to drip excess ink (couple of ml) for a short period of time. During this time do not allow the printhead to have direct contact with an absorbant material (paper towel, etc) as this will cause the cartridge to continue leaking. (You may put the cartridge with the printhead facing down in a dry sink for 3-5 minutes). Use a soft cloth to dap off the excess ink from the printhead (bottom of the cartridge) once the dripping has cease.

7. Use the provided Print Head Cleaning Wipes to clean the bottom of the printhead. (This step is not necessary but recommended to remove dried on ink from the printhead). If you run out of the provided wipes, you may use a damp cotton cloth with water or rubbing alcohol to achieve the same result.

8. Insert the cartridge back into the printer. It is NORMAL for the printer to display a low ink notification after the refill process. You can hold the STOP/RESET button the printer for 5+ seconds to disable the ink level indicator for this cartridge.This does not affect the cartridge’s ability to print. For more information regarding this and steps to disable this notification see our Troubleshooter for a step by step tutorial.

9. Print 5 test pages to settle the cartridge and test for printing irregularities. (Test pages are available under the download section of our support database). You may also print a picture (color cartridge) or word document (black cartridge) to achieve similar results. It is also recommended to run the Alignment Tool or Cleaning Tool from the printer – (Most printers with a Digital LCD will have this option available directly on the printer. Printers without a display will generally have this setting under Printer Preferences/Settings from the PC/Mac.)
