How do I find the Toner Sensors?
Press the cover release and open the top cover fully and note the positions of the four
cartridges:
There are two sensors for each toner: one on the drum (TS1) and one on the machine
(TS2).
TS1: The toner sensor is located on the right hand side of the drum
TS2: The Toner sensor on the machine can be found on the right hand side panel of
the machine on the inside (see image below).
The sensor is enclosed in an oval shaped hole, this works in conjunction with the toner
sensor located on the right hand side of the drum.

Toner Sensor Errors
A toner sensor error is displayed when the machine is no longer able to detect the
toner cartridge / drum unit, or is no longer able to determine how much toner is left in
the units.
How to clear the Toner Sensor Errors
If your printer displays a toner sensor error please power off the printer and check the
following:
 Check that all the blue toner levers are pushed firmly towards the back of the
machine. Remove and replace the toner cartridge into the drum unit.
 Check if the sensors need to be cleaned. The sensor is located behind a plastic
cover on the side of the drum (see below). Remove the plastic cover and give the
silver arm a clean with something small and soft (lint free), any toner that has built
up on the sensor will be a very fine powder and should be easy to remove.

Check if the sensor lever on TS1 has been pushed up. Once you have cleaned the
arm, check that the sensor lever has been pushed up (see Correct Position below).

Correct Position Incorrect Position
If it is incorrect it can sometimes result in the blanking disc not being pulled out of the
way, this results in the sensor on the machine not picking up the sensor on the drum.
Pushing the disc up will resolve the problem. The disc will not fall back down again,
providing that the blue Toner Lever is pushed firmly to the back of the machine.
After all these checks are completed place the cover back on the side of the drum. It
should go back on the same way it came off. If you are unable to fit the plastic cover on
the drum, you can leave it off as it will not stop the drum from printing.
Install the drum and toner in the machine and switch on, if you still have an error
message please contact your local UniNet Support Representative for further
assistance.
