The toner cartridge is a key component in ensuring print quality. Over time and with frequent use, the toner can dwindle, leading to a decline in print quality. Therefore, in this article, we will introduce the detailed steps for replacing the toner cartridge of Brother HL-L2370DW printer, including preparation, replacement operation and subsequent maintenance recommendations.


There are a few key steps to follow before you begin replacing the HL-L2370DW toner cartridge in your Brother HL-L2370DW.

  1. Model confirmation and resource utilization

Make sure you know the exact model number of your printer and the model number of the toner cartridge you need first. This information can usually be found on a label on the back of the printer or by visiting the support section of the Brother website. This step is very important because using the wrong model of toner cartridge can cause printing problems or damage the printer.

  1. Choosing the right toner cartridge

When purchasing a toner cartridge, you can either choose an original Brother toner cartridge or a reputable third-party brand. Original toner cartridges guarantee the highest compatibility and print quality, while third-party brands may offer a more economical option. Whichever you choose, check the shelf life and recommended storage conditions of the toner cartridge to ensure that your purchase is in top condition.

  1. Prepare tools and work area

Preparation involves preparing some basic tools and a suitable work area. This should include a pair of rubber gloves and a clean cloth to keep them clean and avoid direct contact with the toner. Choose a well-lit and well-ventilated work area to ensure safety and comfort during operation.

  1. Safety and environmental precautions

Before you begin replacing the toner cartridge, it is recommended that you read the printer’s user manual to familiarize yourself with any specific safety instructions and operating procedures. It is also necessary to understand how to properly dispose of and recycle old toner cartridges in consideration of the environment.

Printer Shutdown and Preparation

Make sure the printer is in a safe condition before you begin the actual steps for replacing the toner cartridge:

  • Ensure that the printer is powered off: For safety reasons, be sure to completely power off the printer before replacing the toner cartridge. This not only prevents accidents from occurring during the replacement process but also helps to protect the internal components of the printer.
  • Open the front cover: Gently open the front cover of the printer. During this process, take special care to inspect and avoid causing damage to any special connections or fragile parts.
  • Removing the old toner cartridge: Remove the old toner cartridge to be replaced carefully, avoiding applying excessive force or incorrectly manipulating parts that may be affected. Throughout the process, be sure to keep your hands and the inside of the printer clean to avoid toner contamination.

Installing the New Toner Cartridge

Installing a new toner cartridge also requires precise and careful handling:

  1. Unpacking the new toner cartridge: Carefully unpack the new toner cartridge, taking care not to touch the chip part of the cartridge or the toner. Keep your hands clean during the operation to avoid spillage of toner.
  2. Gently shake the toner cartridge: Before installation, gently shake the toner cartridge horizontally a few times, which helps to make the toner more evenly distributed inside the cartridge. But remember not to shake it too much to prevent toner leakage.
  3. Install the toner cartridge correctly: Carefully align the toner cartridge with the slot inside the printer and slowly push it in. When you hear a “click” sound, it indicates that the toner cartridge is firmly installed in place.
  4. Checking the Toner Cartridge Installation: After the operation is complete, double-check to make sure that the toner cartridge is installed correctly, that it is not loose, and that all parts are properly seated.

Printer Reboot and Test

  • Closing the front cover: after installing the toner cartridge, gently close the front cover of the printer. Make sure that the cover is fully closed and that there are no unclosed parts.
  • Reconnect the power: Reconnect the power to the printer and turn on the printer. Observe any unusual lights or sounds during startup to make sure everything is OK.
  • Print a test page to confirm successful installation: Print a test page from the printer setup or a connected computer. Check the print quality of the test page, including text clarity and image uniformity, to confirm that the toner cartridge is installed correctly.

Maintenance and Usage Tips

To ensure that your Brother HL-L2370DW printer is always performing at its best, here are some important maintenance and usage tips:

  1. Check the remaining toner cartridge level regularly

Regularly checking the amount of toner remaining in the toner cartridge is key to maintaining continuous high quality printouts. Most modern printers have a feature that indicates the amount of toner remaining, which can be viewed on the printer’s display or through connected computer software. This not only helps you avoid running out of toner at a critical time, but also allows you to plan ahead for the purchase of a new toner cartridge.

  1. Regularly clean the inside of the printer

Dust and debris inside the printer may affect the print quality. It is recommended that you gently wipe the inside of the printer, especially the toner cartridge installation area, with a clean, soft cloth every time you replace the toner cartridge. Be sure to follow the cleaning guidelines in your printer manual to avoid damaging sensitive parts.

  1. Keep the printer software up to date

Regularly checking and updating your printer’s software and drivers will ensure that your printer is compatible with the latest operating systems and applications. This can usually be done through the printer manufacturer’s official website. Software updates not only improve the performance of your printer, but also fix known security vulnerabilities and other issues.

  1. Check the toner cartridge and printer settings first in case of printing problems

In case of poor print quality or other problems, first check if the toner cartridge is installed correctly and if there is enough toner. Next, check the printer settings to ensure that the correct paper type and print quality settings have been selected. Sometimes a simple adjustment of the settings or reinstallation of the toner cartridge can solve the problem.

  1. Follow printer usage recommendations

In order to extend the life of your printer, it is important to follow the manufacturer’s recommendations regarding print volume and paper type. Avoid overloading your printer and make sure you use the recommended paper type and size.


By following these steps, you can ensure efficient operation and quality prints from your Brother HL-L2370DW printer. Regularly replacing the toner cartridge and properly maintaining the printer will help prolong the life of the device and ensure that your printing tasks are completed smoothly.
