How to refill Compaq 180844-001, 180846-001, 180848-001, 337710-001, 337715-001



1. Remove the cartridge cap by prying with a knife or flat screwdriver (as seen below).

2. Attach needle to syringe and load syringe with ink.

3. Use a tooth pick to poke inside hole, verify the color sequence. Insert needle into correct cartridge ink hole. Make sure needle reaches to bottom of cartridge.

4. SLOWLY inject the ink into the cartridge. Stop if the ink begins to well up from the fill hole. DO NOT OVERFILL. These cartridges are very inclined to cross-contaminate from the bottom. You must hold the cartridge up and watch the print head as you inject the ink. As soon as you see ink coming out STOP and wipe it off with a tissue. Then back the needle up and continue. When the ink keeps coming out the print head STOP because the chamber is full.

5. Repeat steps until all colors have been filled.

6. Clean off the cartridge.  Use a tape to secure the cap on cartridge body.

7. Reinstall in printer and run one or two cleaning cycles until the cartridge begins to print correctly. Do not exceed three cleaning cycles.

PLEASE NOTE: Should the cartridge print in streaks, first refill the cartridge, then start a cleaning cycle with your printer software. If the problem remains, fill a bowl with ½ inch of warm water (max temperature 90F) and soak the cartridge in it for 1 to 2 hours. Use an empty syringe without needle to pressure air from above into the openings. By doing so produce a high pressure within the ink chambers, and press the air bubbles out of the nozzle chamber.
