When replacing or installing a toner cartridge, closing the top cover with the cartridge unlocked (Figure 1) may cause the printer to fail to detect the level of toner correctly. As a result, the printer may display a "Toner Low" or "Replace Toner" message. In addition, toner may not get transferred to the developer unit, affecting the print quality (Figure 2).
Figure 1. The toner cartridge is unlocked.
Figure 2. An example of affected print quality.
If you are using the Normal toner cartridge:
Remove the toner cartridge and then reinstall it, ensuring that you lock it correctly.
Figure 3. Toner cartridge installation.
You should now be able to use the toner cartridge until the normal end of its life.
If you are using the Return toner cartridge:
Remove and reinstall the cartridge correctly as above.
Check your printer's firmware version (see below):
If your firmware revision is 26815 or lower then we recommend updating the firmware to version 26830. You will then be able to use the Return cartridge until the normal end of its life.
If your version is 26830 or greater, please do not change the firmware.
