REPLACING THE WASTE TONER BOX
The waste toner box collects residual toner that is produced during printing. When the used toner box is full, the display
will show "Replace used toner container". Follow the procedure below to replace the used toner box.
Open the front cover.2
Release the used waste toner box.
The waste toner box will fall forward as shown.
Gently support the box with your hands as you let it fall forward
as far as it will go.
Remove the waste toner box.
Hold the box by both hands and lift it up slowly.
If the waste toner box falls too far forward, it will not be possible
to remove it. (Remove the box when it is at an angle of about
30 degrees.)
Install the new waste toner box.
Insert the box from above at a slant. (The direction opposite to
when you removed it.)
Push the waste toner box into the
machine.
Push the box in until it clicks into place.

It took me some time but I found the sollution:

Remove the powercord from the printer.

Open the front door and remove the first toner.

Close the front door and open the top door, remove the photo conductor.
When the front door is closed, you can turn the toner trommel and move it so that the second toner gets in the remove position.

Open the front door and remove the toner.

Close the front door and turn the trommel.

Repeat those steps until all are removed.

steps for removing and replacing the toner cartridges:
-before removing the toner cartridges, disconnect the A/C power cable from the back of the system & remove the printer's top cover
-rotate the securing lever upward to unlock the toner cartridge
-lift the cartridge out of the chassis, each toner housing and cartridge is color-coded and labeled for easy identification of toner cartridge color locations
-just reverse the previous steps to replace the toner cartridges

yes it's necessary to remove waste toner, because n long time the waste toner jamed the clining (I think in the 3050 the waster toner drop by a pipe inside the drum)

There is a manual removal option. Open the front cover. Then the top. Remove the drum. Close the front cover. (leave the top open). Move the toner housing unit so the required toner is accessable from the back. Remove.

Replace drum. Restart printer. The housing unit shoud rotate the empty spot to the front so you can insert the new toner.

Good luck.

You can download the operation manual for that machine, on page 4-5 they explain how to replace the toner and have pictures showing how.
here is the text on how to replace.

Adding Toner
1 Open the front cover.
2 Pull down the toner hopper lock lever and pull the toner
hopper out slowly until it stops.
3 Tap on the top of the toner cartridge 5 times. Hold the
new toner cartridge vertically and vigorously shake it
up and down about 20 times, then invert the cartridge
and again shake it up and down about 20 times. This will
loosen the toner and allow it to flow more easily into the
toner hopper.
4 Place the new toner cartridge with the tabs in the
notches as shown.
5 Slide the toner cartridge along the guides over the toner
hopper.
6 Hold the toner cartridge with one hand while pulling on
the sealing tape to remove it.
7 Tap on the top of the toner cartridge 5 times to start the
flow of toner into the toner hopper.
l If the toner cartridge was sufficiently shaken as described in step
3, it will take about 50 seconds for the cartridge to empty. Do not
remove the cartridge until it is empty. If not empty, tap on the top
of the cartridge again until empty.
8 Slide the empty toner cartridge back along the guides
and remove it.
l The cartridge opening will be closed as it is moved back along
the guides.
9 Slide the toner hopper into the copier and return the
toner hopper lock lever into place.
10 Close the front cover.
NOTE:
Add only one cartridge of toner.

the chip is faulty on the black cartridge, change the black and it'll work, alternately you can out it diagnostic made and run without the cartridges being monitored
