Step 4
Removing the grounding screw
- Remove the 6 mm Phillips #2 screw from the grounding wire of the ADF motor harness.
- Torque: 0.40±0.10 N•m
- The Brother service manual lists torques for all screws, but proper torque should not be necessary.

Step 5
- In the proceeding steps, you will disconnect the following cables:
- CIS flat cable
- Scanner motor harness
- ADF motor harness
- Document detection/document scanning position sensor harness
In the proceeding steps, you will disconnect the following cables:
CIS flat cable

Step 10
Opening the scanner harness holder
- Insert a spudger between the scanner harness holder and frame to release the tab. There is a second tab on the opposite side.
- Lift the scanner harness holder out of its frame.
- Reassembly Note: Before reattaching the harness holder, it is advisable to reattach the cover support (Step 2) to minimize tension on the wiring harnesses.

Step 11
Securing the scanner harness holder
- Push on the tab to secure the scanner harness holder to the scanner cover.
- De-route the document detection/document scanning position sensor harness and the ADF motor harness from the scanner harness holder.
- During reassembly, put a 20mm-thick pad (book, stack of paper) on the scanner glass, close the scanner cover, then route the document detection/document scanning position sensor harness and the ADF motor harness through the harness holder. This will ensure the proper harness tension to allow scanning of thick books.

Calion,
Quite good instructions. However I needed to get to the power supply, and most of this was very useful, because there are 2 screws supporting the power supply you need to take out with the uper cover removed and the fronf left corner moulding removed. But step 14 and 15 are not necessary, and some of the cable disconnections are not needed.
On step 2 also showing the support damper (removed) with an arrow showing the hook on the back of the support damper would have saved lots of time as I had great difficulty with this step.
Thanks again
Ian
