Some laser printers, including many business-oriented black and white and color units, use an imaging drum that is separate from the toner cartridge. The drum is coated with a chemical that develops a charge when light strikes it, making toner stick to it. Over time, imaging drums break down and lose their effectiveness and require replacement. To signal you that your drum is nearing the end of its life, your printer's drum light will flash. Once it starts doing this, you should obtain a new drum so that you can replace the old one before the printer stops working or its print quality declines.

Flip the "Power" switch to turn the printer on. Wait for it to warm up.

Open the printer's top cover by lifting its front edge up and rotating it vertically.

Push the old imaging drum slightly away from you and lift it upward to remove it from the printer.

Wipe any dust or debris off of the clear plastic strip that sits inside the printer under where the drum was. Use a dry microfiber cloth to avoid leaving deposits or scratches on the plastic.

Remove the new drum from its plastic bag, set it down and pull the orange rings and orange shipping spacers away from the drum. Rotate and then pull the orange locks on the two ends of the drum assembly to remove them from the cartridge.

Lift the orange protective cover away from the imaging drum surface.

Lower the new drum into the printer by lining up its white rollers with the arrow markings inside the printer. You might need to use a little bit of force to properly seat it.

Close the printer's top cover.

Press the "Go" button on the printer's main control panel and wait for its "Ready" light to turn on.

Open the printer's front cover by placing your hands on either side of the printer and rotating it down. The printer should be turned on for this process.

Reset the blinking drum light by holding down the printer's "Go" button for approximately four seconds. Do not release it until the four light-emitting diode indicator lights on the printer's control panel light up.

Pull the combined drum and toner assembly out of the printer. It should come straight out.

Remove the toner cartridge from the drum assembly. Press down on the blue lever to release the cartridge. Set it down carefully since it is full of toner and can spill.

Remove the new drum unit from its packaging.

Replace the toner cartridge in the new assembly by putting it back in the same space it occupied in the old assembly. When you have it correctly oriented, you will hear it lock and you will see the blue lever lift up.

Insert the drum and toner assembly black into the printer and shut the front cover.

Press the printer's "Power" button to turn it on.

Press the large release button in the upper-left corner of the printer's front panel to lower the front cover.

Grab the handle on the toner cartridge assembly and use it to pull the cartridge out of the printer.

Press the button below the handle on the base of the cartridge assembly and, with your other hand, use the handle to pull the toner cartridge away from the drum assembly.

Remove the new drum from its packing materials.

Slide the toner cartridge into the toner assembly by lining up the white rollers on the cartridge with the corresponding slots, which are marked with white arrows. Once you have them lined up, push the cartridge into the drum assembly until it clicks.

Insert the cartridge and drum assembly back into the printer. To do this, line up the blue arrows on the assembly with the blue arrows inside the printer and slide the cartridge in until it stops.

Hold the printer's "Cancel" button until all of the lights on its control panel flash in a sequence. This will reset the drum counter.


The procedures in this article work for the specific model numbers identified. The process may also work for similar printers. The best way to be sure that you are using the correct procedure for your printer is to follow the one in its owner's manual or user guide.

Consider covering your windows if you are changing the drum on a sunny day. This will protect the components from intense light.

When you take the drum assembly out of your printer, place it on a piece of paper or put it in the packaging that came with your new drum. Doing this will help to prevent any remaining toner from making a mess.


Do not touch the surface of the imaging drum -- your fingerprints can ruin it.

Do not expose the imaging drum to light for more than 15 seconds because light can damage it.
