Question about Brother MFC-7340 All-In-One Laser Printer
SOURCE: Brother 4070 CDW Drum Unit Error
The green tabs that you have to slide are under the color cartridges, so remove the three color cartridges and you will see three green tabs, to slide the tab across the wire you have to first open the translucent plastic wire cover, then slide the green tab across the wires and return it to it's original position, close the wire covers, replace the color cartridges, and reassemble the printer. All the Best
