Interconnect PCA Removal The Interconnect PCA is a connector board that connects the Power Supply and the DC Controller with the the Fuser Assembly. The Fuser Assembly connects directly into the Interconnect PCA. The Power Supply and the DC Controller have wiring harnesses that connect them to the Interconnect PCA. Note Re-assembly of the the Interconnect PCA requires a small tie-wrap. Be sure to have a tie-wrap available before beginning the disassembly. Remove the interconnect as follows: 1 Remove the Formatter Cage, the Power Supply, the Fuser Assembly, the High Voltage Power Supply, and the Rear Door. 2 Remove the (1) screw from the right-side PC tray Rail Cover (see Figure 6-58, callout 1). 3 Release the latch (see Figure 6-58, callout 2), slide the Rail Cover to the rear of the printer and remove the cover.
