Media specifications
The printer accepts a variety of media, such as cut-sheet paper, including up to 100%
recycled fiber content paper; envelopes; labels; transparencies; and custom-size paper.
Properties such as weight, composition, grain, and moisture content are important factors
that affect printer performance and output quality. Media that does not meet the guidelines
that are outlined in this manual can cause the following problems:
● Poor print quality
● Increased jams
● Premature wear on the printer, requiring repair
NOTE
CAUTION
Some media might meet all of media specifications and still not produce satisfactory results.
Improper handling, unacceptable temperature and humidity levels, and other variables over
which Hewlett-Packard has no control can affect print quality. Before purchasing large
quantities of media, make sure that it meets the requirements that are specified in the user
guide and in theHP LaserJet Printer Family Print Media Guide, which is available for
download at http://www.hp.com/support/ljpaperguide. Always test paper before buying large
quantities.
Using media that does not meet HP specifications can cause problems for the printer,
requiring repair. This repair is not covered by the HP warranty or service agreements.

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 paper is hygroscopic; it absorbs and loses moisture
rapidly.
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 media.
Unopened paper in sealed reams can remain stable for several months before use. Opened
packages of media 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 printer
performance. The required condition is 20° to 24°C (68° to 75°F), with a relative humidity of
45% to 55%. The following guidelines should be helpful when evaluating the paper's 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 media is to rewrap it tightly in its moisture-
proof wrapping. If the printer environment is subject to extremes, unwrap only the
amount of media to be used during the day's operation to prevent unwanted moisture
changes.
ENWW Media specifications 13

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
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: You should use envelopes that are compatible with the heat and
pressure of the printer.
● Size: You should use only envelopes within the following size ranges.
● Minimum: 76 x 127 mm (3 x 5 inches)
● Maximum: 216 x 356 mm (8.5 x 14 inches)
2
(28 lb) or
NOTE
Use only tray 1 to print envelopes. You might experience some jams 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 you are storing
and handling the paper correctly (see
envelopes in the printer driver (see
Printing and paper storage environment). Choose
Printer drivers).
Envelopes with 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 the seam extends all the
way to the corner of the envelope as illustrated below.
1
2
1 Acceptable envelope construction
2 Unacceptable envelope construction
Envelopes with adhesive strips or flaps
Envelopes with a peel-off adhesive strip or with more than one flap that folds over to seal
must use adhesives compatible with the heat and pressure in the printer. The extra flaps and
strips might cause wrinkling, creasing, or even jams and might even damage the fuser.

Envelope margins
The following gives 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 inches) 89 mm (3.5 inches)
NOTE
CAUTION
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's 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.
Labels
To avoid damaging the printer, use only labels recommended for laser printers. To prevent
serious jams, always use tray 1 to print labels and always use the rear output bin. Never
print on the same sheet of labels more than once or print on a partial sheet of labels.
When selecting labels, consider the quality of each component:
● Adhesives: The adhesive material should be stable at 200°C (392°F), the printer's
fusing temperature.
● Arrangement: Only use labels with no exposed backing between them. Labels can peel
off sheets with 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 labels with wrinkles, bubbles, or other indications of separation.
Transparencies
Transparencies used in the printer must be able to withstand 200°C (392°F), the printer's
fusing temperature.
CAUTION
ENWW Media specifications 15
To avoid damaging the printer, use only transparencies recommended for use in
HP LaserJet printers, such as HP-brand transparencies. (For ordering information, see
Ordering parts and supplies.)

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

Selecting which tray is used for printing
You can select how the printer pulls media from the trays. The following sections provide
information about configuring the printer to pull media from specific trays.
Understanding tray order
Customizing tray 1 operation
Printing by type and size of media (locking trays)
Feeding media from tray 1 manually
Understanding tray order
When the printer receives a print job, it selects the tray by trying to match the requested
media type and size with what has been loaded in the trays. Using an "autoselect" process,
it searches all available trays for the paper that satisfies the request, starting with the bottom
tray and ending with the top tray (tray 1). The printer begins printing the job as soon as it
finds the correct type and size.
NOTE
The "autoselect" process occurs only if no specific tray is requested for the job. If a specific
tray is requested, the job prints from the requested tray.
● If media is loaded in tray 1 and tray 1 is set TRAY 1 SIZE=ANY and TRAY 1
TYPE=ANY on the PAPER HANDLING menu, then the printer will always pull media
from tray 1 first. See
● If the search fails, then a message appears on the printer control-panel display
requesting that you load the correct media type and size. You can load that media type
and size, or you can override the request by selecting a different type and size at the
printer control panel.
● If a tray runs out of media during a print job, then the printer automatically switches to
any tray that contains the same media type and size.
The autoselect process changes somewhat if you customize tray 1 operation (as explained
Customizing tray 1 operation) or if you set tray 1 for manual feed (as explained in Feeding
in
media from tray 1 manually).
Customizing tray 1 operation for more information.
ENWW Selecting which tray is used for printing 35
Page 50
Customizing tray 1 operation
The printer can be set to print from tray 1 if it is loaded, or to print only from tray 1 if the type
of media that is loaded is specifically requested. See the user guide.
Setting Explanation
TRAY 1 SIZE=ANY
TRAY 1 TYPE=ANY
TRAY 1 SIZE= or
TRAY 1 TYPE= a type
other than ANY
The printer usually pulls media from tray 1 first unless tray 1 is empty or
closed. If you do not keep media in tray 1 all the time, or if you use tray 1
only to manually feed media, keep the default setting of TRAY 1
SIZE=ANY and TRAY 1 TYPE=ANY on the Paper Handling menu.
The printer treats tray 1 like the other trays. Instead of looking for media in
tray 1 first, the printer pulls media from the tray that matches type and size
settings that are selected in the software.
In the printer driver, you can select media from any tray (including tray 1)
by type, size, or source. To print by type and size of media, see
type and size of media (locking trays).
Printing by
You can also determine whether the printer shows a prompt to ask if it can pull media from
tray 1 if it cannot find the type and size that you requested in another tray. You can set the
printer to always prompt you before pulling from tray 1 or only prompt you if tray 1 is empty.
Set the USE REQUESTED TRAY setting on the System Setup submenu of the Configure
Device menu.

Printing by type and size of media (locking trays)
Printing by type and size is a way to be sure that print jobs always print on the media that
you want. You can configure the trays for the type, such as plain or letterhead, and size,
such as letter or A4, that is loaded in them.
If you configure the trays this way and then select a certain type and size in the printer
driver, the printer automatically selects the tray loaded with that type or size. You do not
have to select a specific tray (selecting by source). Configuring the printer this way is
especially helpful if the printer is shared, and more than one person loads or removes media
frequently.
Some older model printers have a feature that "locks out" trays to prevent printing on the
wrong media. Printing by type and size eliminates the need to lock trays. For more
information about types and sizes that each tray supports, see
print media.
Supported types and sizes of
NOTE
NOTE
To print by type and size from tray 2 or tray 3, it might be necessary to unload tray 1 and
close it, or to set TRAY 1 SIZE and TRAY 1 TYPE to types other than ANY on the Paper
Handling menu at the printer control panel. For more information, see
operation. Settings in a program or the printer driver override control-panel settings.
(Program settings generally override printer-driver settings.)
Customizing tray 1
To print by type and size of media
1. Be sure to load the trays correctly. (See the user guide.)
2. At the printer control panel, open the Paper Handling menu. Select the paper type for
each tray. If you are unsure about which type you are loading, such as bond or recycled,
check the label on the media package.
3. Select the paper-size settings at the printer control panel.
● Tray 1: Set the paper size on the Paper Handling menu if the printer is set to TRAY
1 TYPE= a type other than ANY. If custom paper is loaded, also set the custompaper size on the Paper Handling menu. (For more information, see the user guide.)
● Tray 2 and optional tray 3: Set the paper size on the Paper Handling menu.
These trays do not support custom sizes.
4. In the program or printer driver, select a type other than Auto Select.
The type and size settings can also be configured in the HP Web Jetadmin software for
networked printers.

NOTE
If the SIZE and TYPE are set to ANY, and MANUAL FEED PROMPT is set to UNLESS

PROMPT is set to ALWAYS, then the printer will prompt you to load media, even if tray 1 is
set to SIZE=ANY and TYPE=ANY.
If you have selected MANUAL FEED=ON at the printer control panel, this setting will
override the printer driver, and all print jobs that you send to the printer will request manually
fed paper in tray 1 unless a specific tray has been selected in the printer driver. If this feature
is to be used only occasionally, it is best to set MANUAL FEED=OFF at the printer control
panel and to select the manual feed option in the printer driver on a job-by-job basis.

Selecting the correct fuser mode
The printer automatically adjusts the fuser mode based on the media type to which the tray
is set. For example, heavy paper, such as card stock, might need a higher fuser-mode
setting in order to make the toner adhere better to the page, but transparencies need the
LOW fuser-mode setting to avoid damage to the printer. The default setting generally
provides the best performance for most print-media types.
The fuser mode can be changed only if the media type has been set for the tray that you are

Using a higher fuser mode, such as HIGH 1 or HIGH 2, improves the ability of the toner to
adhere to paper, but it might cause other problems, such as excessive curl. The printer

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 required as a result of using a non-HP print cartridge
will not be covered under the printer warranty.
Using genuine HP supplies ensures the availability of all HP printing features.
Print-cartridge authentication
The printer will let you know if a print cartridge is not a genuine HP print cartridge when you
insert it into the printer. If you believe that you purchased a genuine HP supply, visit us at
http://www.hp.com/go/anticounterfeit.
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 temperature should be
between -20°C and 40°C (-4°F to 104°F). The relative humidity should be between 10% and
90%.
CAUTION

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 5% coverage
(typical for a business letter), the HP print cartridge lasts an average of 6,000 (Q6511A) or
12,000 (Q6511X) pages.
At any time, you can verify life expectancy by checking the supply level, as described in

Cartridge-low and cartridge-out conditions
The printer 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 printer control panel shows the ORDER CARTRIDGE
message. The message first appears when about 16% (6,000-page cartridge) or about 8%
(12,000-page cartridge) 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 printer to continue printing until the cartridge runs out, but you might
prefer to have the printer 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 printer to stop, in the CONFIGURE DEVICE menu, under SYSTEM SETUP,

Cleaning the printer
Over time, particles of toner and paper accumulate inside the printer. This can cause printquality problems during printing. Cleaning the printer eliminates or reduces these problems.
Clean the paper path and print-cartridge areas every time that you change the print cartridge
or whenever print-quality problems occur. As much as possible, keep the printer from dust
and debris.
Cleaning the outside
Clean the outside of the printer with a cloth that has been dampened with water.
CAUTION
Do not use ammonia-based cleaners on or around the printer.
Cleaning the paper path and print-cartridge areas
Over time, particles of toner and paper accumulate inside the printer. This can cause printquality problems during printing. Cleaning the printer eliminates or reduces these problems.
To clean the inside of the printer
1. Turn the printer off and unplug the power cord.
2. Open the top cover.
3. Remove the print cartridge.
CAUTION
58 Chapter 4 Maintenance ENWW
To prevent damage to the print cartridge, do not expose it to light for more than a few
minutes. Be careful not to touch the transfer roller (the black, rubber roller located
underneath the print cartridge). Skin oils on the roller can cause print-quality problems.
Page 73
4. With a dry, lint-free cloth, wipe any residue from the paper path area and the print
cartridge cavity.
5. Reinstall the print cartridge and close the top cover.
NOTE
If the print cartridge is difficult to reinstall, make sure that the registration plate has been
flipped back down into position and that you have pushed the print cartridge firmly in place.
6. Plug in the power cable and turn the printer on.
ENWW Cleaning the printer 59
Page 74
Cleaning the fuser
Run the printer 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.
To ensure optimum print quality, HP recommends that you use the cleaning page every time
that you replace the print cartridge or on an automatic interval that you can set up.
The cleaning procedure takes about 2.5 minutes to complete. A CLEANING message
appears on the printer control panel display while the cleaning is taking place.
To run the cleaning page
In order for the cleaning page to work correctly, print the page on copier-grade paper (not
bond, heavy, or rough paper).

Engine control system
The engine control system coordinates all printer functions, according to commands that the
formatter sends. It drives the laser/scanner system, the image formation system, and the
pickup/feed/delivery system.
The engine control system contains the following components:
● Dc controller
● High-voltage PCA

66 Chapter 5 Theory of operation ENWW
Page 81
Figure 5-4. Engine control system circuit diagram
ENWW Engine control system 67
Page 82
Laser/scanner system
The laser/scanner system receives video signals from the dc controller and the formatter and
converts the signals into latent images on the photosensitive drum.
Figure 5-5. Laser/scanner system
68 Chapter 5 Theory of operation ENWW
Page 83
Pickup/feed/delivery system
The pickup/feed/delivery system consists of several types of feed rollers and sensors. The
dc controller uses two motors and two solenoids to drive the rollers. Three media-detection
sensors detect media as it passes through the printer. If media does not reach or pass each
sensor within a specified time period, the dc controller determines that a jam has occurred
and alerts the formatter.
The following components are identified in
● M1, main motor
● M2, fuser motor
● SL1, tray 1 pickup solenoid
● SL2, tray 2 pickup solenoid
● PS2, duplexer media-detection sensor
● PS4, tray 2 media-detection sensor
● PS901, top-of-page sensor
● PS902, tray 1 media-detection sensor

Image-formation system
Laser printing requires the interaction of several different technologies, including electronics,
optics, and electrophotographics, to provide a printed page.
Figure 5-7. Print cartridge diagram
Each process functions independently and must be coordinated with the other printer
processes. Image formation consists of the following five processes:
Figure 5-8.
● Electrostatic latent-image formation
● Developing
● Transfer
● Fusing
● Drum cleaning
The five processes contain eight steps, which are shown in the figure
formation system and described in the following sections.
Image-formation system
Figure 5-8. Image-
ENWW Image-formation system 71
Page 86
Step 1: Primary charging
Dc and ac biases are applied to the primary charging roller, which transfers a uniform
negative potential to the photosensitive drum.
Figure 5-9. Primary charging
Step 2: Laser beam exposure
The laser beam scans the photosensitive drum to neutralize negative charges on parts of
the drum. An electrostatic latent image is formed on the drum where negative charges were
neutralized.
72 Chapter 5 Theory of operation ENWW
Page 87
Step 3: Developing
The developing cylinder comes in contact with the photosensitive drum to deposit toner onto
the electrostatic latent image.
NOTE
The charges on the exposed area of the drum are shown as positive in Figure 5-10.
Developing. The charges are actually negative, but they are more positive than the charges
on the developing cylinder.
Figure 5-10.
Developing
Toner acquires a negative charge through friction from the developing cylinder and the
blade. When the negatively charged toner comes in contact with the drum, the toner adheres
to the electrostatic latent image. The image on the drum becomes visible because of the
toner.
Step 4: Transfer
The transfer charging roller, to which a dc positive bias is applied, imparts a positive charge
on the print media. When the print media comes in contact with the photosensitive drum, the
toner is transferred to the print media.

sensitive

Transfer roller

Figure 5-11. Transfer
ENWW Image-formation system 73
Page 88
Step 5: Separation
The elasticity of the print media causes its separation from the photosensitive drum. A static
charge eliminator aids separation by weakening any electrostatic adhesion.
Figure 5-12. Separation
Step 6: Fusing
The dc negative bias applied to the fusing film strengthens the holding force of the toner on
the print media and prevents the toner from scattering.
Figure 5-13. Fusing
74 Chapter 5 Theory of operation ENWW
Page 89
Step 7: Drum cleaning
The cleaning blade scrapes the residual toner off of the photosensitive drum and deposits it
into the waste toner case.
Figure 5-14. Drum cleaning
ENWW Image-formation system 75
Page 90
Print cartridge memory system
The memory tag is a nonvolatile memory built into the print cartridge. The cartridge usage
condition is detected as the engine controller reads or writes the data stored on the memory
tag. The engine controller renews the information in the prescribed timing and reads or
writes it from or to the memory tag.
The engine controller commands the memory tag to read or write with the following
conditions:
● Read
● Power is ON
● The top cover is closed
● A command has been received from the formatter
● Write
● A page of media is printed.
● A command has been received from the formatter
When the engine controller failed to read or write three times in a row, it determines that the
memory tag is abnormal and notifies the formatter of a "cartridge memory abnormality
warning".
