state, but the product does not
print.
The product does not print.A component is defective.Perform an engine test to
verify print-engine
components.
1.
Print an engine test
page. See

2. If the engine test page
does not print, check all
the connectors on the
engine controller PCA,
and reconnect any
cables that are
connected incorrectly.
3. If, after checking the
connectors, the error
persists, replace the
engine controller PCA.
See

							Troubleshooting process
Determine the problem source 
The following table includes basic questions to ask the customer to quickly help define the problem or
problems.
General topicQuestions
Environment●Is the product installed on a solid, level surface (± 1°)?
● Is the power-supply voltage within ± 10 volts of the specified power source?
● Is the power-supply plug inserted in the product and the outlet?
● Is the operating environment within the specified parameters?
● Is the product exposed to ammonia gas, such as that produced by diazo copiers
or office cleaning materials?
NOTE:
Diazo copiers produce ammonia gas as part of the coping processes.
Ammonia gas (from cleaning supplies or a diazo copier) can have an adverse
affect on some product components (for example, the print-cartridge OPC).
● Is the product exposed to direct sunlight?
Paper●
Does the customer use only supported paper?
● Is the paper in good condition (no curls, folds, or distortion)?
● Is the paper stored correctly and within environmental limits?
Input trays●Is the amount of paper in the tray within specifications?
● Is the paper correctly placed in the tray?
● Are the paper guides aligned with the stack?
Print cartridge●
Is the print cartridge installed correctly?
Transfer roller and fuser●Are the transfer roller and fuser installed correctly?
Print-cartridge door●Is the print-cartridge door closed?
Condensation●Does condensation occur following a temperature change (particularly in winter
following cold storage)? If so, wipe affected parts dry or leave the product on
for 10 to 20 minutes.
● Was a print cartridge opened soon after being moved from a cold to a warm
room? If so, allow the print cartridge to sit at room temperature for 1 to 2 hours.
Miscellaneous
●Check for and remove any non-HP components (for example, a print cartridge)
from the product.
● Remove the product from the network and make sure that the failure is with the
product before beginning troubleshooting.

							Power subsystem
Power-on checks
Turn on the power. If the control-panel LEDs do not illuminate, perform the power-on checks to find the
cause of the problem.
1.Verify that the product is plugged into an active electrical outlet that delivers the correct voltage.
2. Verify that the power switch is in the on position.
3. Make sure that the product makes the expected start-up sounds.
NOTE: The overcurrent/overvoltage protection circuit in the low-voltage power supply unit might
be functioning. Turn the product off, unplug the power cord, and turn the product on. If the product
does not function, the fuse melts, or the power supply is malfunctioning, replace the engine
controller unit. See 
Engine controller PCA on page 80 .
