How to Fix “Non-Genuine Toner” Error on Kyocera M2040dn, M2135dn, and M2640idw

If your Kyocera printer is showing the “Non-genuine toner is installed” message, you don’t need to replace the cartridge immediately. This error occurs because the printer cannot verify the chip on a third-party or refilled toner.

The 5-Second Solution

To bypass this error and continue printing, follow these steps:

  1. Locate the [OK] and [Stop] (or Reset) buttons on your control panel.
  2. Press and hold both buttons simultaneously for 5 seconds.
  3. A message will appear asking for confirmation. Select “Yes”.

Note: This will allow you to print, but the printer may stop showing the exact toner level.

Need a Reliable Replacement?

To avoid the “Non-genuine” message in the future, I recommend using high-quality toners with updated chips. Important: Please check your printer’s region before ordering. North American models typically use TK-1172, while European models use TK-1170.

For USA / North America (TK-1172)

For Europe / UK (TK-1170)

Time for an Upgrade?

If your current printer is reaching its end of life or the repair costs are too high, I recommend upgrading to the latest generation. The Kyocera ECOSYS MA4000wfx is the direct successor to the M2040dn, offering faster print speeds (42 ppm), enhanced security features, and the same legendary reliability.
