Instructions for recycling the HP Q7551X Toner Cartridge:
  1. After pulling the toner from a laser printer the first step is to open the screw of side cover.
  2. Now take the side cover off
  3. After you have taken outside cover, the next step is to take out drum unit. Hold it from a white portion(gear) and pull it.
  4. Now you need to plug-out PCR roller.
  5. Slightly push PCR rod to right-side with some sharp-edge tool and then move PCR slightly upward and take it out leftwards.
  6. Next step is to separate the waste unit and ink unit, which are joined together with the help of pins. So you have to take out the pins which are on both sides of the cartridge.
  7. After pushing pin from inside , it’s time to get it out from the outer side since it has plunged out after being pushed from inside.
  8. After you remove pins from both sides of the toner cartridge, you have to remove a spring.
  9. Next step is to set-apart two main units of the cartridge . One unit is a waste unit and the other is called ink-unit. Hold the toner and pull both units apart.
  10. View of Waste Ink Unit and closer view of Spring which is to be removed to open waste ink unit.
  11. Remove spring and then remove plastic cover.
  12. Now remove the screws of the waste unit to get apart the wiper-blade and then remove the waste-Ink which was collected in this unit.
  13. Now that you have managed to open up Wiper-Blade , you should clean the waste collector unit and Blade part. Wiper-Blade should be cleaned with a soft cloth and not with a brush as the brush can put scratches on blade.
  14. Next, you have to re-assemble waste-unit part. First, fit the wiper-blade and then the plastic cover.
  15. Re-fit plastic cover so that it fixes into the cut/groove.
    Now Fit the spring back to its position.
  16. Now what you have done so far is that you have opened the waste ink-unit , cleaned it and then closed that unit. Now begins the main part that is to refill the laser printer toner cartridge. So now, take the other unit where the ink resides. Open it and fill the Ink (dry) in it then close it and finally re-assemble the two units which were separated earlier.
  17. After removing the side cover, you can see a white plastic cover, you have to remove this and fill here the toner-ink.
  18. Remove white plastic cover, now you are ready to refill the toner but before that do not forget to “Shake the Ink Bottle before use”. After removing the cap of the bottle you can apply plastic nozzle-cap which you normally get along with a bottle or you can ask for one from the vendor.
  19. Now it’s time to refill and the close the cap.
  20. Now you have to join together the two units i.e Waste-Unit and Ink-Unit. Make sure to align them.
  21. Next step will be to RE-Insert PINS (remember..!!!!) you plugged out from both sides.
  22. Now after you have inserted pins (with hands ,no tool required) , it’s time to insert PCR roller.
  23. Time to install Drum-Unit back to its position i.e onto drum holding pin.
  24. After Re-installing drum, Fit the side-cover.
  25. And Finally Reinsert Spring .


If you are intending to buy replacement ink and toner cartridges, you should also think about what you are going to do with the empty HP 51X Toner Cartridge. There are millions of ink and toner cartridges used each year and statistics suggest that 95% of them go to landfill.

Here are some ways that help us to dispose of the empty ink and toner correctly.
  • Prevent this material entering into the sewers or water supplies.
  • Instead of throwing empty HP Q7551X Toner Cartridge into the bin for landfill you can collect them and when you have enough gathered you can make the trip to the local Council amenity/recycling centre. There are containers in all refuse sites that will accept used ink and toner cartridges.
  • The favourite way is to find the third party manufacturers in your nearby area that can take your empty toner cartridges. These third party manufacturers buy the empty toners, refill them and resell them into the market. The third party manufacturers compensate you for providing them the empty toners for recycling.
  • The another way is that you can directly contact the toner cartridge manufacturers. Many companies have their own recycling plants, where they take back the used empty toner cartridges.
If we all start this practice today, we can surely make a difference to our own carbon footprint in upcoming future.
