1 Is the power on?
When the product is connected
to a grounded power source
and is turned on, the control
panel shows Hewlett Packard
with moving cursors indicating
that the firmware code is
loading, and the main motor
rotates for approximately 45 to
60 seconds. When the
firmware is done loading,
Scanner bulb warming up
might appear on the control-
panel display, and the scan
head moves back and forth for
10 to 15 seconds. If you lift the
scanner cover, you will see that
the scanner bulb is lit. Near the
end of this time, the automatic
document feeder (ADF) motor
turns on for about two seconds.
No power as a result of a failed power source,
cable, switch, or fuse.
1. Verify that the product is plugged in.
2. Verify that the power cable is functional
and that the power switch is on.
3. Check the power source by plugging
the product directly into the wall or into
a different outlet.
Motor does not start. 1. Verify that the product is plugged into
a working electrical receptacle.
2. Verify that the print cartridge is
installed correctly. Follow the
instructions on the control panel to
remove and replace the cartridge.
3. Verify that the top cover is closed.
ADF motor does not start. Open the ADF cover and remove any
orange shipping tape inside the ADF.
Verify that the ADF connector is connected
correctly to the scanner.
If the ADF motor still does not rotate, replace
the ADF. See
ADF assembly on page 115.
Scanner bulb does not light. If the scanner bulb does not light, verify that
the wire-harness connectors from the
scanner to the formatter are connected
correctly.
If the error persists, replace the following
components one at a time until the problem
is resolved: scanner assembly, formatter.
See
Scanner/ADF assembly on page 117
and
Formatter on page 132.
2Does Ready appear in the
product control panel?
The control panel should
function without error
messages.
Control panel shows an error.
Asian control panel characters do not display
correctly.
See Control-panel messages on page 169
for a list of common messages that will help
you correct the error.
If the product uses the Asian control panel
and the formatter was recently replaced,
make sure that the Asian character display
PCA is installed correctly and fully seated in
the formatter connector (H3).
