How to Install HP LaserJet 4240n Toner Replacement Cartridges?

  1. Open the printer's top cover.
  2. Grab the toner cartridge that needs to be replaced, then carefully pull it out from the printer.
  3. Get your new CompAndSave HP 4240n toner cartridge. Open the cartridge over a sink or garbage can to avoid any mess in case of a powder leak, as sometimes, factories tend to overfill the toner cartridges. Avoid touching the bottom part of the toner, then remove the covering tape that is usually bright in color as well as the plastic protective case, if there is, before installing it.
  4. Carefully align and insert the new HP LaserJet 4240n cartridge into the slot until it is firmly seated in place.
  5. Close the printer's top cover.

HP LaserJet 4240n Toner Replacement Cartridges FAQ's

How many times can you refill a laser toner cartridge?

A genuine toner cartridge can be refilled up to 3 times. However, refilling a toner is not recommended since you have to replace some parts of the toner as well. If you think of refilling an empty toner cartridge, please bear in mind the following pros and cons. The major advantage of refilling is cost-efficiency. It'll be a way cheaper option rather than purchasing a new genuine one. On the other hand, refilled toner cartridges can have issues with the print quality and durability. Toner consists of different parts such as rolling gears, cleaning blades, etc. These parts wear out over time which can cause noise when printing, low-quality printouts, and even leakage inside the printer. Another thing to look into is the imaging drum, which holds the image before the toner powder is applied to the paper. Just like the toner, parts of the imaging drum also wear and tear over time.

To sum it all up, we highly encourage you to have it refilled through stores that offer refilling services instead. If you choose to purchase a new one, we at CompAndSave offer a wide variety of cheap printer toner cartridges at a much lesser price without compromising its quality. Our toners are manufactured to meet or exceed the OEM specifications, which will save you from all the trouble of going through the process of refilling a toner cartridge.

Does laser toner dry out?
Toner cartridges are powder-based and not liquid-based. This means that they do not dry out. But, if a toner cartridge was not used for a long time, there's a possibility that the toner powder is not evenly distributed inside. This can cause uneven prints and smudges when printing. To resolve this issue, you may shake the toner cartridge sideways to distribute the toner powder evenly. For more information, click Troubleshooting Tips and you will be redirected to the right page.
