Why Does My Printer Say Low Toner When I Just Changed It?


When your printer indicates 'low toner' even after you've just replaced it, this can lead to confusion and disrupt your work.

This issue could arise due to various factors, and understanding them can help in resolving the problem efficiently.

In this guide, we'll explore the common reasons behind this issue and offer insights on how to address them effectively.

Common Causes for the Low Toner Message

Knowing the reasons your printer shows a 'low toner' message is important for proper troubleshooting.

Here are some common reasons:

➜ Incorrect Installation

The issue could be that the new cartridge is not installed properly. This is a common problem that can lead to the printer not recognizing the new toner cartridge. 

To fix this, you should reinstall the cartridge. Make sure that it's correctly seated in the printer and locked into place. 

A properly installed cartridge will ensure that the printer detects the toner level accurately and eliminates the 'low toner' message.

➜ Cartridge Model

It's important to use the right model of toner cartridge for your printer. Using a cartridge that doesn't match your printer model can cause problems. 

This might make the printer incorrectly show a 'low toner' message, even with a new cartridge. It's a good idea to double-check that the cartridge model is the exact one recommended for your printer to avoid this issue. 

Always make sure to check that the cartridge you're using is the one meant for your printer to avoid these problems.

➜ Firmware or Software Glitches

Printers, like any other technology, rely on firmware and software to operate. 

Sometimes, glitches or bugs in this software can lead to incorrect toner level readings, resulting in the printer displaying a 'low toner' message even with a new cartridge. 

Keeping your printer's firmware updated can help, as manufacturers frequently release updates that address known issues and enhance functionality. 

Additionally, a simple restart of the printer can often reset the system and resolve these glitches.

➜ Quality of Replacement Toner

It's important to note that not all toner cartridges are of the same quality. When using  non-OEM (Original Equipment Manufacturer) toner cartridges, there's a possibility they may not align perfectly with your printer's specifications. 

These cartridges can sometimes struggle to communicate properly with your printer's sensors, which can result in inaccurate toner level readings or other compatibility issues.

➜ Physical Obstructions or Damage

If the toner cartridge is damaged or if there are obstructions in the cartridge compartment, it can prevent the cartridge from being installed properly, leading to false 'low toner' alerts. 

Inspect both the cartridge and the printer for any visible damage or foreign objects that might be causing blockages.  A clear and clean cartridge area is important for proper printer functioning and accurate toner level detection.


In summary, a printer showing a "low toner" message after you've put in a new cartridge can be due to several reasons. Knowing what these reasons are helps you fix the problem more easily. 

Paying attention to how you install the cartridge and keeping your printer clean and up-to-date can help prevent this issue. 

This way, you can keep your printer working well and avoid unnecessary confusion with toner levels.
