If I clean out the water toner cartridge on a SM

If I clean out the waste toner cartridge on a KM Magicolor 7450, and put it back into the unit, will it work? Or is there a counter on it which will prevent it from working?

It will be fine just be sure to put it in a plastic bag and shake it out. Cuase it will go all over the place. Those are always back ordered and can never get one when you need it. Just be sure to clean the waste toner cart before putting it back into the unit.

I've replaced the toner cartridge and waste toner bottle, but the display still says 'toner low' and 'waste toner near full'. It refuses to print, even with the old cartridges.

Then you mite want to clean the sensor that monitor the waster toner box pull out the waste toner box and look for the area that show clear plastic then look for those area of the machine and blow the old toner from those areas waste toner mite have gotten on the sensor saw they can not see the clear plastic and think that the waste toner cart is still full.

How can I remove the drum from the printer?

Replace the drum unit.
Follow the procedure below to replace the drum unit.

The Brother machine has separate consumables the toner cartridge and the drum unit. Verify you replace only the drum unit and not the toner cartridge. If you want to know their difference, refer to "What is the difference between the toner cartridge and the drum unit?"

Caution Do NOT use flammable substances near the machine. Do NOT use any type of spray to clean the inside or outside of the machine. Doing this may cause a fire or electrical shock.

  • While removing the drum unit, handle it carefully because it may contain toner. If toner scatters on your hands or clothes, wipe or wash it off with cold water at once.
  • After you have just used the machine, some internal parts of the machine will be extremely hot. When you open the front or back cover (back output tray) of the machine, DO NOT touch the shaded parts shown in the illustration. If you do this, you may get burned.
  1. Open the front cover.
  1. Slowly take out the drum unit and toner cartridge assembly.
replacedrum_02.gif Caution
  • We recommend that you put the used drum unit and toner cartridge assembly on a clean, flat surface with a sheet of disposable paper or cloth underneath it in case you accidentally spill or scatter toner.
  • To prevent damage to the machine caused by static electricity, DO NOT touch the electrodes shown in the illustration.
  1. Push down the green lock lever and take the toner cartridge out of the drum unit.
Note Discard the used drum unit according to local regulations, keeping it separate from domestic waste. Be sure to seal up the used drum unit tightly in a suitable bag so that toner powder does not spill out of the unit. If you have questions, call your local waste disposal office.
  • Wait to unpack a new drum unit until immediately before you put it in the machine. Exposure to direct sunlight or room light may damage the drum unit.
  • To avoid print quality problems, DO NOT touch the shaded parts shown in the illustrations.
  1. Unpack the new drum unit.

  2. Put the toner cartridge firmly into the new drum unit you hear it lock into place. If you put the cartridge in properly, the green lock lever will lift automatically.
Caution Make sure that you put in the toner cartridge properly or it may separate from the drum unit.
  1. Clean the primary corona wire inside the drum unit by gently sliding the green tab from right to left and left to right several times.
Caution Be sure to return the green tab to the home position (1). If you do not, printed pages may have a vertical stripe.
  1. Put the new drum unit and toner cartridge assembly in the machine.
  1. Press Clear/Back.

    For MFC users:
    To confirm you are installing a new drum, press 1.

    For DCP users:
    To confirm you are installing a new drum, press the Up Arrow key.

  2. When the LCD shows Accepted, close the front cover.
