Service check. 06 Cover closed switch/cable

N	FRU	Action
1	Toner cartridge	Make sure the toner cartridge is correctly installed and that the right and left cartridge tracks are not loose or broken. Make sure the cover closed switch activation tab on the toner cartridge is not broken and that the tab correctly activates the cover closed switch spring.
2	Cover closed switch/cable assembly	Check the cover closed switch for proper mechanical operation. If incorrect, repair as necessary. Disconnect the cover closed switch cable from J8 at the system board and measure the voltage at J8-3. It measures approximately +5 V dc. If the voltage is incorrect, replace the system board. If the voltage is correct, check the voltage at J8-1. If the voltage measures greater than +1.0 V dc, replace the system board. If the voltage is correct, check the continuity between J8-1 and J8-3 on the cable. If no change in continuity occurs as the switch is activated, replace the cover open switch/cable assembly. If the continuity changes as the switch is activated, replace the system board.
