Minimum system requirements for e-mail functionality
To use the e-mail functionality, the MFP must be connected to an IP-based server that has simple
mail transfer protocol (SMTP). This server can either be on the local area network or at an outside
Internet service provider (ISP). HP recommends that the MFP be located on the same local area
network (LAN) as the SMTP server. When using an ISP, you must connect to the ISP by using a
digital subscriber line (DSL) connection. When obtaining e-mail services from an ISP, ask the ISP to
provide the correct SMTP address. Dial-up connections are not supported. If no SMTP server is on
the network, third-party software is available that allows you to create an SMTP server. However,
purchase and support of this software is the customer's responsibility.

to the left of the scanner glass.
NOTE After moving the MFP, unlock the scanner. The MFP cannot initialize correctly when
the scanner is locked.
The MFP is heavy and should be lifted by three people. One person should stand at the front of the
MFP and should grip the sides, and the other two people should stand at the sides of the MFP and
should grip the sides and back. Remove the output bin or other optional output accessories before
moving the MFP. To lift the MFP, grip the lift handles that are on the sides and on the back of the
MFP. Do not attempt to lift the MFP by gripping any other part of the MFP. If the bottom of the MFP
is attached to an optional accessory (such as a 500-sheet feeder or a storage cabinet), the
accessory latches must be unlocked before moving the MFP.
WARNING! To prevent possible injury to yourself or damage to the MFP, separate the MFP
from any currently installed optional accessories (for example an optional feeder or a stapler/
stacker) before lifting the MFP.
CAUTION When placing the MFP onto the 500-sheet feeder, be sure to place it directly over
the alignment pins.
Locking and unlocking optional accessories
For more stability to prevent the MFP from tipping over, the optional 500-sheet feeders and the
cabinet are automatically locked to the bottom of the MFP. When accessories are installed, verify

Printing and paper-storage environment
Ideally, the printing and paper-storage environment should be at or near room temperature, and not
too dry or too humid. Remember that paper is hygroscopic; it absorbs and loses moisture rapidly.
www.hp.com/support/ljpaperguide).
emissions when heated to 200°C (392°F) for 0.1 second
Heat works with humidity to damage paper. Heat causes the moisture in paper to evaporate, while
cold causes it to condense on the sheets. Heating systems and air conditioners remove most of the
humidity from a room. As paper is opened and used, it loses moisture, causing streaks and
smudging. Humid weather or water coolers can cause the humidity to increase in a room. As paper is
opened and used it absorbs any excess moisture, causing light print and dropouts. Also, as paper
loses and gains moisture it can distort. This can cause jams.
As a result, paper storage and handling are as important as the paper-making process itself. Paper
storage environmental conditions directly affect the feed operation.
Care should be taken not to purchase more paper than can be easily used in a short time (about
3 months). Paper stored for long periods might experience heat and moisture extremes, which can
cause damage. Planning is important to prevent damage to a large supply of paper.
Unopened paper in sealed reams can remain stable for several months before use. Opened
packages of paper have more potential for environmental damage, especially if they are not wrapped
with a moisture-proof barrier.
The paper storage environment should be properly maintained to ensure optimum MFP
performance. The required condition is 20° to 24°C (68° to 75°F), with a relative humidity of
Media specifications 19
45% to 55%. The following guidelines should be helpful when evaluating the paper-storage
environment:
■ Paper should be stored at or near room temperature.
■ The air should not be too dry or too humid (due to the hygroscopic properties of paper).
■ The best way to store an opened ream of paper is to rewrap it tightly in its moisture-proof
wrapping. If the MFP environment is subject to extremes, unwrap only the amount of paper to be
used during the day's operation to prevent unwanted moisture changes.
Envelopes
Envelope construction is critical. Envelope fold lines can vary considerably, not only between
manufacturers, but also within a box from the same manufacturer. Successful printing on envelopes
depends upon the quality of the envelopes. When selecting envelopes, consider the following
components:
■
Weight: The weight of the envelope paper should not exceed 105 g/m
2
(28 lb) or jamming might
occur.
■ Construction: Prior to printing, envelopes should lie flat with less than 6 mm (0.25 inch) curl,
and should not contain air.
■ Condition: Envelopes should not be wrinkled, nicked, or otherwise damaged.
■ Temperature: Use envelopes that are compatible with the heat and pressure of the MFP.
■ Size: Use only envelopes that are within the following size ranges:
■ Minimum: 76 x 127 mm (3 x 5 inches)
■ Maximum: 216 x 356 mm (8.5 x 14 inches)
NOTE Use only tray 1 or the optional envelope feeder to print on envelopes. Some jams
might occur when using any media with a length less than 178 mm (7 inches). This might be
caused by paper that has been affected by environmental conditions. For optimum
performance, make sure to store and handle the paper correctly (see
Printing and paper-
storage environment). Select envelopes in the printer driver.
20 1 Product information
Envelopes that have double side seams
Double side-seam construction has vertical seams at both ends of the envelope rather than diagonal
seams. This style might be more likely to wrinkle. Be sure that the seam extends all the way to the
corner of the envelope, as illustrated.
Envelopes that have adhesive strips or flaps
Envelopes that have a peel-off adhesive strip or with more than one flap that folds over to seal must
use adhesives that are compatible with the heat and pressure in the MFP. The extra flaps and strips
might cause wrinkling, creasing, or jams, and might even damage the fuser.
Envelope margins
The following table shows typical address margins for a commercial #10 or DL envelope.
Type of address Top margin Left margin
Return address 15 mm (0.6 inch) 15 mm (0.6 inch)
Delivery address 51 mm (2.0 inches) 89 mm (3.5 inches)
NOTE For the best print quality, position margins no closer than 15 mm (0.6 inch) from the
edges of the envelope. Avoid printing over the area where the envelope seams meet.
Envelope storage
Proper storage of envelopes helps contribute to print quality. Envelopes should be stored flat. If air is
trapped in an envelope, creating an air bubble, then the envelope might wrinkle during printing.
Media specifications 21
Labels
CAUTION To avoid damaging the MFP, use only labels that are recommended for use in
laser printers. Never print on the same sheet of labels more than once or print on a partial
sheet of labels.
Label construction
When selecting labels, consider the quality of each component:
■ Adhesives: The adhesive material should be stable at 200°C (392°F), the MFP's fusing
temperature.
■ Arrangement: Only use labels that have no exposed backing between them. Labels can peel off
sheets that have spaces between the labels, causing serious jams.
■ Curl: Prior to printing, labels must lie flat with no more than 13 mm (0.5 inch) of curl in any
direction.
■ Condition: Do not use sheets of labels that have wrinkles, bubbles, or other indications of
separation.
NOTE Select labels in the printer driver.
Transparencies
Transparencies used in the MFP must be able to withstand 200°C (392°F), the MFP's fusing
temperature.
CAUTION To avoid damaging the MFP, use only transparencies recommended for use in
HP LaserJet printers, such as HP-brand transparencies. (For ordering information, see
order parts, supplies, and accessories.)
NOTE Select transparencies in the printer driver.

Country-/region-specific safety statements
Laser safety statement
The Center for Devices and Radiological Health (CDRH) of the U.S. Food and Drug Administration
has implemented regulations for laser products manufactured since August 1, 1976. Compliance is
mandatory for products marketed in the United States. The printer is certified as a "Class 1" laser
product under the U.S. Department of Health and Human Services (DHHS) Radiation Performance
Standard according to the Radiation Control for Health and Safety Act of 1968.
Since radiation emitted inside the printer is completely confined within protective housings and
external covers, the laser beam cannot escape during any phase of normal user operation.
WARNING! Using controls, making adjustments, or performing procedures other than those
specified in this user guide may result in exposure to hazardous radiation.

Service approach
MFP repair normally begins by using the MFP internal diagnostics and the following three-step
process.
1 Isolate the problem to the major system (for example, the host computer, the network or server,
or the MFP system).
2 Determine if the problem is located in the accessories, the scanner assembly, or in the MFP
engine.
3 Troubleshoot the problem using the procedures in Chapter 7.
After a faulty part is located, the MFP can usually be repaired at the assembly level by replacing field
replaceable units (FRUs). Some mechanical assemblies might need to be repaired at the
subassembly level. Hewlett-Packard does not support replacement of components on the printed
circuit assembles.

Secure Disk Erase
You might need to protect deleted data from unauthorized access on the MFP hard drive. Secure
Disk Erase is a security feature that you can use to securely erase print and copy jobs from the hard
drive.
Secure Disk Erase offers the following levels of disk security:
■ Non-Secure Fast Erase. This is a simple file-table erase function. Access to the file is removed,
but actual data is retained on the disk until it is overwritten by subsequent data-storage
operations. This is the fastest mode. Non-Secure Fast Erase is the default erase mode.
■ Secure Fast Erase. Access to the file is removed, and the data is overwritten with a fixed
identical character pattern. This is slower than Non-Secure Fast Erase, but all data is
overwritten. Secure Fast Erase meets the U.S. Department of Defense 5220-22.M requirements
for the clearing of disk media.
■ Secure Sanitizing Erase. This level is similar to the Secure Fast Erase mode. In addition, data
is repetitively overwritten by using an algorithm that prevents any residual data persistence. This
mode will impact performance. Secure Sanitizing Erase meets the U.S. Department of Defense
5220-22.M requirements for the sanitization of disk media.
Security features 51
Data affected
Data affected (covered) by the Secure Disk Erase feature includes stored jobs, proof and hold jobs,
disk-based fonts, disk-based macros (forms), and temporary files that are created during the print
and copying process.
NOTE Stored jobs will be securely overwritten only when they have been deleted through
the RETRIEVE JOB menu on the MFP after the appropriate erase mode has been set.
This feature will not impact data that is stored on flash-based product non-volatile RAM (NVRAM)
that is used to store default settings, page counts, and similar data. This feature does not affect data
that is stored on a system RAM disk (if one is used). This feature does not impact data that is stored
on the flash-based system boot RAM.
Changing the Secure Disk Erase mode does not overwrite previous data on the disk, nor does it
immediately perform a full-disk sanitization. Changing the Secure Disk Erase mode changes how the
MFP cleans up temporary data for jobs after the erase mode has been changed.
Gaining access to Secure Disk Erase
Use HP Web Jetadmin to gain access to and set the Secure Disk Erase feature.
Additional Information
For additional information about the HP Secure Disk Erase feature, see the HP support flyer or go to

■ Use a soft, lint-free cloth dampened with water, or with water and a mild detergent.
Cleaning the touchscreen
Clean the touchscreen whenever it is necessary to remove fingerprints or dust. Wipe the
touchscreen gently with a clean, water-dampened, lint-free cloth.
CAUTION Use water only. Solvents or cleaners can damage the touchscreen. Do not pour
or spray water directly onto the touchscreen.
Cleaning the scanner glass
■ Clean the scanner glass only if dirt is visible, or if you are experiencing a decrease in copy
quality, such as streaking.
■ Clean the scanner glass by wiping it gently with a clean, slightly damp, lint-free cloth. Use an
ammonia-based surface cleaner only when a water-dampened cloth does not clean the scanner
glass. Spray or pour the cleaner onto the cleaning cloth. Do not spray or pour the cleaner onto
the scanner glass.
CAUTION Do not pour or spray liquids directly onto the scanner glass. Do not press hard on
the glass surface. (You could break the glass.)
Cleaning the fuser
Use the MFP cleaning page to keep the fuser free of toner and paper particles that can sometimes
accumulate. Accumulation of toner and particles can cause specks to appear on the front or back
side of your print jobs.
CAUTION Do not attempt to clean the fuser with water or any other liquid. Use only the
internal cleaning page to clean the fuser.
To ensure optimum print quality, HP recommends that you use the cleaning page every time you

Calibrating the scanner
Calibrate the scanner to compensate for offsets in the scanner imaging system (carriage head) for
ADF and flatbed scans. Because of mechanical tolerances, the scanner's carriage head might not
read the position of the image accurately. During the calibration procedure, scanner offset values are
calculated and stored. The offset values are then used when producing scans so that the correct
portion of the document is captured.
Scanner calibration should be carried out only if you notice offset problems with the scanned images.
The scanner is calibrated before it leaves the factory. It needs to be calibrated again only rarely.
Before calibrating the scanner, print the calibration target.
To print the calibration target
1 Place letter- or A4-size paper in tray 1, and adjust the side guides.
2 Touch DIAGNOSTICS
3 Touch CALIBRATE SCANNER.
4 Print the first pass of the calibration target.
5 Place the first pass of the calibration target in tray 1 so that the arrows are facing into the MFP.
6 Print the second pass. The final calibration target must look like the following figure.
CAUTION If the calibration target does not look like the figure shown here, the
calibration process will fail and the quality of scans will be degraded. The black areas
must extend completely to the short edges of the page. If they do not, use a black marker
to extend the black areas to the edge of the page.
7 Place the calibration target face-up into the ADF, and adjust the side guides.

Performing preventive maintenance
The MFP requires periodic maintenance to maintain optimum performance. A control-panel message
alerts you when it is time to purchase the preventive maintenance kits. Separate maintenance
procedures are required for the printer-portion of the MFP and for the ADF.
Printer preventive maintenance
You should replace certain parts when the PERFORM PRINTER MAINTENANCE message appears
on the control-panel display.
After printing 215,000 pages, the MFP alerts you to order a maintenance kit. The message can be
temporarily cleared for approximately 10,000 pages by using the CLEAR MAINTENANCE
MESSAGE item on the RESETS submenu. When the page count reaches 225,000, you can no
longer clear the message and you must install the maintenance kit. To check the number of pages
that the MFP has printed since new maintenance-kit components were installed, print either a
configuration page or a supplies-status page.
The printer maintenance kit includes the following items:
■ Fuser
■ Rollers (transfer, feed, and separation)
■ Installation instructions
For the installation procedures, see chapter 6.
NOTE The printer maintenance kit is a consumable item and is not covered under the
original MFP warranty or under most extended warranties.

64 4 Maintenance
Managing the print cartridge
This section provides information about HP print cartridges, their life expectancies, how to store
them, and how to identify genuine HP supplies. Information also appears about non-HP print
cartridges.
HP print cartridges
When you use a genuine HP print cartridge, you can obtain several types of information, such as the
following:
■ Amount of toner remaining
■ Estimated number of pages remaining
■ Number of pages printed
Non-HP print cartridges
Hewlett-Packard Company cannot recommend use of non-HP print cartridges, either new or
remanufactured. Because they are not HP products, HP cannot influence their design or control their
quality. Service or repair that is required as a result of using a non-HP print cartridge will not be
covered under the MFP warranty.
Using genuine HP supplies ensures the availability of all HP printing features.
Print-cartridge authentication
The MFP will let you know if a print cartridge is not a genuine HP print cartridge when you insert it
into the MFP. If you believe that you purchased a genuine HP supply, go to
anticounterfeit.
www.hp.com/go/
Print-cartridge storage
Do not remove the print cartridge from its package until you are ready to use it.
Always store the print cartridge in the proper environment. The storage temperature should be
between -20°C and 40°C (-4°F to 104°F). The relative humidity should be between 10% and 90%.
CAUTION To prevent damage to the print cartridge, do not expose it to light for more than a
few minutes.
Print-cartridge life expectancy
The life of the print cartridge depends on the amount of toner that print jobs require and the length of
life for the components inside the cartridge. When printing text at approximately 5% coverage (typical
for a business letter), the HP print cartridge lasts an average of 18,000 pages. The page-yield
specification that HP provides is a general guideline. Actual yield can vary according to usage
conditions.
At any time, you can verify life expectancy by checking the supply level, as described in
the supply level.
Checking

receive alerts by e-mail or as a pop-up message or taskbar icon. To check the supplies status by
using the HP Toolbox software, click the Status tab, and then click Supplies Status.
To check the supply levels by using HP Web Jetadmin
In HP Web Jetadmin, select the MFP. The device status page shows supply-level information.
Cartridge-low and cartridge-out conditions
The MFP alerts you if the print cartridge is low on toner or out of toner.
When the cartridge is low on toner or drum life
When the cartridge is low, the control panel shows the ORDER CARTRIDGE message. The
message first appears when about 15% of the life remains in the print cartridge. This percentage is
set with the intent of providing approximately 2 weeks of typical use before the cartridge is depleted.
You should have time to purchase a new cartridge before the old cartridge is depleted.
The default is for the MFP to continue printing until the cartridge runs out, but you might prefer to
have the MFP stop instead of continuing when the ORDER CARTRIDGE message first appears—for
example, if you want print quality to remain consistently high during print jobs, or if you do not want
the cartridge to run out during a long print job. To configure the MFP to stop, in the CONFIGURE
DEVICE menu, under SYSTEM SETUP, set CARTRIDGE LOW to STOP. Then, when REPLACE
TART
CARTRIDGE appears, the MFP will stop printing. You can resume printing by pressing S
each print job.

When the cartridge is out of toner or drum life
The REPLACE CARTRIDGE message appears in one of these situations:
■ When the print cartridge is out of toner. If CARTRIDGE OUT is set to CONTINUE (in the
SYSTEM SETUP submenu of the CONFIGURE DEVICE menu), the MFP continues printing
without interaction until the cartridge reaches the end of drum life. HP does not guarantee print
quality after the REPLACE CARTRIDGE message first appears. Replace the print cartridge as
soon as possible. (See
