Check DC supply voltage to the Engine
Logic Board:
1. Remove the I/P Board Cover, Upper,
and Lower Rear Covers.
2. Turn the printer power On.
3. Measure the voltage at these points:
P/J526- 2 <=> ground +5.0 V
P/J526- 4 <=> ground +24.0 V
Are the voltage levels correct?
Go to Step 4. Replace the LVPS
(
page 8-92). If the
problem persists, verify
the wire harness to the
Engine Logic board. If
the wiring checks out,
replace the Engine
Logic Board
(
page 8-89).

2. Turn the printer power On.
3. Measure the voltage at these points:
P/J526- 6 < = > ground +5.0V
P/J526- 8 < = > ground +24.0V
Are the voltage levels correct?
All voltages
are present
and problem
persists,
replace the

Step Actions and Questions Yes No
1
Check AC supply voltage to the LVPS.
1. Remove the Bottom Cover.
2. Check that the Finisher power cord is
connected to the printer’s AC Accessory
Panel and turn the printer power On.
3. Measure AC voltage at the following test
points on the LVPS:
J2- 3 <=> J2- 4 120 V (120 Volt Printer)
J2- 3 <=> J2- 4 220 V (220 Volt Printer)
Are the voltages within specification?
Go to Step 2. Verify the
printer’s AC
Accessory Panel
is delivering
power.
