Step 1 – Remanufacturing the toner hopper TN-4100

• Using a flat blade screwdriver – leverage out the DVR end cap
• On the right hand side of the cartridge – remove one screw

• Using a flat blade screwdriver, gently prise off the end plate

• 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-6050 Toner – Using a large flat blade screwdriver gently squeeze between the cartridge bung and the toner hopper and lift out the bung.

Step 2 – Remanufacturing the OPC Drum unit DR-4000

• Remove two screws and lift out the Corona wire assembly

• The Corona wire charges the OPC drum – the Corona wire can be contaminated with toner residue Clean the Corona wire gently with the provided blue cleaner by sliding side to side. Alternatively clean gently with compressed air.
