How to Replace a Drum on a Brother Copier

Brother markets a line of copiers for residential and small business use. These copiers function as expected when regular maintenance and repairs are performed. Damage or wear to the drum unit creates copy-quality problems such as light print, marks, bands, streaks, lines or voids on the copies. If your originals are satisfactory, but your printed copies display problems, the drum may need to be replaced.

Things You'll Need

• New drum
• Paper

Instructions

1. Lay out pieces of paper to cover an area about 18 inches by 18 inches on the table adjacent to the copier.

2. Allow the copier to cool off if it has been running recently.

3. Open the front cover of the copier.

4. Grasp the handle inside the front cover and pull to remove the drum unit and toner cartridge. Remove the unit slowly and do not allow the unit to tip.

5. Set the drum and toner cartridge assembly on the paper set out in step 1.

6. Push the green lock lever on the toner cartridge down, then remove the toner cartridge from the drum unit. Set the toner cartridge aside on the paper. Set the old drum unit aside out of the way.

7. Remove the new drum from its packing material.

8. Insert the toner cartridge into the new drum unit until the cartridge clicks into place. If the cartridge is inserted properly, the green lock lever lifts automatically.

9. Grasp the green tab on the drum unit, then slide it back and forth several times. This action cleans the primary corona wire. Return the tab to its home position indicated by the arrow on the drum unit case.

10. Pick up the drum unit and toner cartridge assembly, then insert it back into the copier. Be certain the assembly is fully seated, but don't force it. Remove and reseat the assembly if you encounter resistance before the assembly is fully seated.

11. Press the "Clear/Back" button.

12. Close the front cover when the control panel displays "Accepted."

Tips & Warnings

• Dispose of the old drum unit in a sealed bag. The unit contains residual toner which will spill if the unit is not sealed.

• Do not unpack the new drum unit until you are ready to replace the old drum. The drum is sensitive to light. Exposure to light--even ambient light in the room--will "burn" the drum if left for more than a few minutes. This "burn" creates copy quality problems which may not be recoverable.

• Do not touch the drum surface with your fingers or allow objects to touch the drum. Oil from your fingers will adhere to the drum and create copy quality problems. The surface of the drum is very tender. Objects that touch the drum will nick or scratch it and create copy quality problems.
