Does the printer turn
on successfully?
When the product is
connected to a grounded
power source, the printer
motor should rotate for
approximately five
seconds.
No power. 1. Verify that the product is plugged in.
2. Verify that the power cable is functional
and that the power switch is on (220v only).
3. Verify that FU102 on the ECU is not
open.
4. If all of these conditions are correct,
replace the ECU.
Printer motor does not
rotate.
1. Verify that the toner cartridge is present.
(See “Toner cartridge” on page 78 for more
information.)
2. Verify that the printer door is closed.
3. Verify that media is loaded in the main
input tray.
4. Verify that the printer paper path and
door sensors are functional.
5. Verify that the motor connector is seated
into the ECU.
6. Verify that the motor is correctly mounted
on the printer chassis.
7. If all of these conditions are correct,
replace the ECU.
8. If, after replacing the ECU, the printer
motor still does not rotate, replace the
motor.

Is the product ready?
The control panel should
function without error light
patterns.
Control panel displays an
error light pattern.
Consult the list of control panel light
patterns later in this chapter to identify and
correct the error.
Control panel is not
functional.
1. Verify that the control panel cable is
seated in the formatter.
2. If the cable is connected correctly,
replace the control panel.

Do engine tests and
self-test pages print?
Print an engine test. (See
page 149.)The engine
test should print without
paper-feed problems or
print-quality problems.
Note
The formatter must be connected to perform an
engine test.
Engine test is not
successful.
Replace the ECU.
Control panel displays an
error light pattern.
Consult the list of control panel light
patterns in this chapter to identify and
correct the error.
Media does not move
smoothly through the
printer paper path.
Isolate printer paper-path problems by
performing a paper-path check, which is
discussed later in this chapter.
Poor print quality. See “Solving image-quality problems” on
page 138.
