Inoperative Printer Troubleshooting Procedure (Continued)
Step Actions and Questions
4 Check AC supply voltage to the LVPS.
1. Remove the Upper Right Cover.
2. Turn the printer power On.
3. Measure AC voltage at the following test
points on the LVPS:
P/J1-1 <=> P/J1- 4
Is the voltage across pins 1 and 4 equal
to 120V or 220V (line voltage).
5 Check AC input continuity.
1. Power the Printer off.
2. Check for continuity between the printer
AC power inlet connector and
T 11 <=>T12
Are these conductive?
6 Check the AC Voltage from the LVPS to the
Power Switch.
Measure AC voltage at the following test
points on the LVPS
P/J 1 – 3 < = > P/J 1 – 6 + 120V or 220 V
Are the voltages measured within
specification?
General Troubleshooting
Yes
Go to LVPS
Procedure
(page 4-5).
Verify the Power
Cord is in good
condition and is
the correct cord. If
necessary,
replace the cord.
Verify or repair
the wiring from
the LVPS to the
Power Switch. If
necessary,
replace Power
Switch
(page 8-86).
No
Go to Step 6.
Verify the GFI
breaker is not
tripped and is
operational. If
problem persists,
repair the AC inlet
connector wiring.
If necessary,
replace the GFI
Breaker
(page 8-94).
Replace the LVPS
(page 8-92).
