ENWW 1
Introduction
This chapter describes the removal and replacement of field-replaceable units (FRUs) only.
Replacing FRUs is generally the reverse of removal. Occasionally, notes and tips are included to
provide directions for difficult or critical replacement procedures.
HP does not support repairing individual subassemblies or troubleshooting to the component level.
Note the length, diameter, color, type, and location of each screw. Be sure to return each screw to its
original location during reassembly.
Incorrectly routed or loose wire harnesses can interfere with other internal components and can become
damaged or broken. Frayed or pinched harness wires can be difficult to find. When replacing wire
harnesses, always use the provided wire loops, lance points, or wire-harness guides and retainers.
Removal and replacement strategy
WARNING! Turn the product off, wait 5 seconds, and then remove the power cord before
attempting to service the product. If this warning is not followed, severe injury can result, in addition to
damage to the product. The power must be on for certain functional checks during troubleshooting.
However, disconnect the power supply during parts removal.
Never operate or service the product with the protective cover removed from the laser/scanner
assembly. The reflected beam, although invisible, can damage your eyes.
The sheet-metal parts can have sharp edges. Be careful when handling sheet-metal parts.
CAUTION: Do not bend or fold the flat flexible cables (FFCs) during removal or installation. Also, do
not straighten pre-folds in the FFCs. You must fully seat all FFCs in their connectors. Failure to fully seat
an FFC into a connector can cause a short circuit in a PCA.
NOTE: To install a self-tapping screw, first turn it counterclockwise to align it with the existing thread
pattern, and then carefully turn it clockwise to tighten. Do not overtighten. If a self-tapping screw-hole
becomes stripped, repair the screw-hole or replace the affected assembly.
TIP: For clarity, some photos in this chapter show components removed that would not be removed to
service the product. If necessary, remove the components listed at the beginning of a procedure before
proceeding to service the product.
2 Chapter 1 Removal and replacement ENWW
Electrostatic discharge
CAUTION: Some parts are sensitive to electrostatic discharge (ESD). Look for the ESD reminder
when removing product parts. Always perform service work at an ESD-protected workstation or mat, or
use an ESD strap. If an ESD workstation, mat, or strap is not available, ground yourself by touching the
sheet-metal chassis before touching an ESD-sensitive part.
Protect the ESD-sensitive parts by placing them in ESD pouches when they are out of the product.
Required tools
#2 Phillips screwdriver with a magnetic tip and a 152-mm (6-inch) shaft length
Small flat-blade screwdriver
Needle-nose pliers
ESD mat or ESD strap (if one is available)
Penlight (optional)
CAUTION: Always use a Phillips screwdriver (callout 1). Do not use a Pozidriv screwdriver
(callout 2) or any motorized screwdriver. These can damage screws or screw threads.

ENWW Electrostatic discharge 3
Service approach
Before performing service
Remove all paper from the product.
Turn off the power using the power button.
WARNING! The power button must be turned off before performing service. Failure to turn off
the power leaves the fuser engaged and prevents it removal.
Unplug the power cable and interface cable or cables.
Place the product on an ESD workstation or mat, or use an ESD strap (if one is available). If an
ESD workstation, mat, or strap is not available, ground yourself by touching the sheet-metal
chassis before touching an ESD-sensitive part.
Remove the print cartridges and imaging drum.
After performing service
Plug in the power cable.
Reinstall the print cartridge.
Load paper in the product.
Post-service test
Perform the following test to verify that the repair or replacement was successful.
Print-quality test
1. Verify that you have completed the necessary reassembly steps.
2. Make sure that the tray contains clean, unmarked paper.
3. Attach the power cord and interface cable or interface cables, and then turn on the product.
4. Verify that the expected startup sounds occur.
5. Print a configuration page, and then verify that the expected printing sounds occur.
6. Send a print job from the host computer, and then verify that the output meets expectations.
7. Clean the outside of the product with a damp cloth.

Removal and replacement procedures
Replace the print cartridges
When a print cartridge approaches the end of its useful life, you can continue printing with the current
print cartridge until it no longer yields acceptable print quality.
Once an HP print cartridge has reached "very low', HP's Premium Protection Warranty on that supply
has ended. All print defects or print cartridge failures incurred when an HP supply is used in continue at
very low mode will not be considered to be defects in materials or workmanship in the supply under the
HP Print Cartridge Warranty Statement.
NOTE: Once an HP print cartridge has reached "very low', the corresponding cartridge light on the
control panel turns on.
1. Press the Cartridge button of the print
cartridge that requires replacement to rotate
the print cartridge carousel for removal.
NOTE: All doors must be closed when
pressing the Cartridge button.
NOTE: Wait until the Cartridge light is
not flashing and the rotation sounds stops
before opening the print cartridge door.
2. Open the print cartridge door.
6 Chapter 1 Removal and replacement ENWW
3. Grasp the old print cartridge by the center
handle and remove.
4. Remove the new print cartridge from the
packaging. Place the used print cartridge in
the bag and box for recycling.
CAUTION: To prevent damage to the print
cartridge, hold the print cartridge at each end.
Do not touch the roller on the print cartridge.
5. Remove the protective shielding from the new
print cartridge.
6. Grasp both sides of the print cartridge and
gently rock the print cartridge to distribute the
toner evenly inside the print cartridge.
7. Remove the tape from the print cartridge. Place
the tape in the print-cartridge box to return for
recycling.
ENWW Removal and replacement procedures 7
8. Grasp the print cartridge by the center handle
and insert into the product.
NOTE: Compare the color label on the print
cartridge to the color label in the carousel slot
to make sure the print cartridge color matches
the carousel position.
CAUTION: If toner gets on your clothing,
wipe it off with a dry cloth and wash the
clothing in cold water. Hot water sets toner
into the fabric.
9. Close the print cartridge door.
NOTE: After closing the print cartridge door,
the Ready light and Attention light will
flash. Allow up to three minutes for the product
to calibrate.
NOTE: If replacing another print cartridge,
you must close the print cartridge door before
pressing the Cartridge button of the next
print cartridge.
10. When printing, if you receive the status alert
message Wrong Cartridge in
Slot, remove the print cartridge from the
specified slot and compare the color label on
the print cartridge to the color label in the slot
to determine the correct print cartridge for the
slot.
8 Chapter 1 Removal and replacement ENWW
Replace the imaging drum
NOTE: The imaging drum installed in this product is covered by the product warranty. Replacement
imaging drums have a one-year limited warranty from the date of installation. The imaging drum
installation date displays on both the configuration page and on the supplies status page when the
imaging drum reaches approximately 30% of its estimated remaining life. HP's Premium Protection
Warranty applies only to the print cartridges for the product.
1. Open the print cartridge door.
2. Open the front cover.
ENWW Removal and replacement procedures 9
3. Lift the two levers that hold the imaging drum.
4. Remove the old imaging drum.
5. Remove the new imaging drum from the
packaging. Place the used imaging drum in
the bag and box for recycling.
10 Chapter 1 Removal and replacement ENWW
6. Remove the protective shielding from the new
imaging drum.
CAUTION: To prevent damage, do not
expose the imaging drum to light for an
extended period of time. Cover the imaging
drum with a piece of paper if it can not be
installed immediately.
CAUTION: Do not touch the green drum.
Fingerprints on the imaging drum can cause
