Solving the Toner Sensor Error Message

When installing a new or compatible cartridge and the toner sensor error message appears on the display.

This is caused by the toner sensor being in the down position.  See picture below:

To solve this issue you must spin the white gear counter clockwise on the opposite side to retract the toner sensor.

Caution: Keep the toner cartridge level and be sure the cartridge lever is in the unlocked position (the toner shutter will be in the closed position) to avoid toner spill.

The toner sensor will retract to the up position.

Reinstall the toner cartridge and the error should be gone!
