Troubleshooting

Verifying power supply operation

Verifying the operation of the power supply involves four steps:

■

Measuring the input voltages

■

Inspecting the power supply fuses

Measuring AC supply voltage

1.

Turn off the printer and unplug it from its power outlet.

2.

With the VOM set to measure AC voltages, measure for power being
supplied to the printer. It should measure between 90 to 132 VAC (115
VAC nominal) or 180 to 264 VAC (220 VAC nominal). Ensure that the
switch is correctly set. Ensure the power measures correctly at the
power outlet and at the printer’s end of the power cord.

If AC power is good then check the line fuse as explained in the following
procedure. If AC power is out of specification, inform the customer to obtain
suitable power.

Inspecting the power supply fuses

A fuse (15A – 110 VAC or 6.3A – 220 VAC) is mounted into the power supply.

1.

Remove the lower rear cover to access the fuse.

2.

With a small flat-blade screwdriver, remove the fuseholder. Visually,
and with a VOM, check to determine that the fuse is good.

If the fuse is good, but the printer's does not power up or print, replace the print
engine.

Determining if the image processor is overloading the engine

1.

Turn off the printer.

2.

Remove the image processor board from the printer engine. This is
explained in Section 8, “Image processor board” on page 8-17.

3.

Turn on the printer.

If the printer powers up and you can print a test print as explained earlier in
“Verifying print engine operation by using its self-test print” on page 6-3, then
the image processor board is bad and must be replaced. If the print engine does
not power up correctly, then it is bad and must be replaced.
