Go to section 7 and troubleshoot a printer problem.
2 Reattach the Finisher to the printer. Remove the Lower Rear Cover, remove the Finisher PWB
Cover (REP 8.5.3.10). Close the Finisher Top Cover or actuate the Top Cover Interlock Switch.
Close the Finisher Front Cover or actuate the Front Cover Interlock Switch. Close the Compiler
Cover or actuate the Compiler Cover Interlock Switches. Switch on printer power.
CAUTION AC line voltage is present on the LVPS PWB. With the protective PWB Top Cover
removed there is a shock danger present. Use extreme caution when working on and
around the LVPS and the Finisher PWB.
Set your meter to read AC voltage. Measure the voltage between P/J2-3 and P/J2-4 on the
LVPS. There is 110 VAC between P/J2-3 and P/J2-4.

Go to section 6 or section 7 and troubleshoot a loss of AC problem.
3 Set your multimeter to read DC voltage. Measure the voltage between P/J505-3 and FG (frame
ground) and between P/J505-4 and FG on the LVPS. There is +5VDC between P/J505-3 and FG
and between P/J505-4 and FG.

between P/J896-A2 and FG on the Finisher PWB. There is +5VDC between P/J896-A1 and FG
and between P/J896-A2 and FG.
