How to Install a Laser Unit Assembly in the Brother DCP-9040CN Digital Laser Copier
Initially, you must open the front cover of your Brother DCP-9040CN Digital Laser Copier, and then open the rear cover. Next, you must detach the rear upper cover by removing the two screws, and then remove the two screws from the rear cover. After that, you must remove the rear cover from the main unit, and then remove the four screws from the left side cover. Now, you must remove the left side cover by detaching the five hooks, and then detach the left side plate by removing the five screws. Once the left side plate is removed, you must remove the right side cover, and then unplug the three connectors from the driver PCB assembly. In the next step of the replacement procedure, you must remove the ADF and FB harnesses from the driver OCB shield, and then unplug the two connectors and the flat cable from the main PCB assembly. After that, you must open the document scanner unit, and then detach the hooks from the joint of the unit. Now, you must remove the document scanner unit from the Brother DCP-9040CN Digital Laser Copier, and then disconnect the four connectors from the main PCB assembly. Once the four connectors are unplugged, you must detach the joint sub cover by removing the screw and releasing the two hooks, and then remove the 14 screws from the joint cover assembly. At this stage of the replacement procedure, you must remove the joint cover assembly by releasing its pin, and then remove the two hook slopes. Next, you must detach the scanner cover by removing the nine screws, and then unplug the two flat cables and the connector from the laser unit assembly. After that, you must remove the seven screws and the four holders from the laser unit assembly, and then remove the exhausted component from the machine. Finally, you must install the new laser unit assembly by executing the current procedure in reverse order, and then reset the life counter for the laser unit assembly by executing the short procedure included below.
