Step 1 – Remanufacturing the toner hopper
• On the right hand side of the cartridge – remove one screw
• Using a flat blade screwdriver – leverage out the DVR end cap
• On the left side of the cartridge take out 3 screws to remove the end plate
• Reset the Toner page counter
• On the gear side of the cartridge remove the black plastic DVR roller extender
• Using a small flat blade screwdriver gently lift out the white DVR retainer – it requires a small inset pin to be released to the right and then pushed in an upwards direction.
• The DVR roller should be gently lifted away from the cartridge
• We cleaned the DVR roller first with Iso-propanol alcohol, and then wash with water and allowed to dry
• In this guide we DO NOT remove the OEM doctor-blade – rather we clean it in place.
a. To do this, fold a piece of paper in half and slide into the cartridge in order to protect to foam adder roller.
b. Using a Q-Tip gently wipe the surface of the doctor-blade clean. We used a small amount of Iso-propanol.
• Once all the cartridge components have been cleaned – replace back into the cartridge.
• Refilling with AQC Group UK compatible replacement Brother HL-2140 Toner – Using a large flat blade screwdriver gently squeeze between the cartridge bung and the toner hopper and lift out the bung.
• Replace the protective travel cover
Step 2 – Remanufacturing the OPC Drum unit DR2100
• Using a small flat blade screwdriver gently lift out the small circlip
• Using a small flat blade screwdriver gently lift out the axle stabilizer
• The OPC unit will now lift out from it’s carriage position
• The Brother HL-2140 uses a corona wire assembly to charge the OPC drum, this assembly can attract ‘dusting’ of toner particles – clean this assembly with compressed air.
• Lift out and replace or clean the OPC drum
• Using either compressed air or vacuum – clean the carriage, transfer roller and drum cleaning brushes, also remove any paper dust.
• Replace all components
