Print-media specifications
This section contains information about specifications for the quality of print media, guidelines for
print media usage, and guidelines for print media storage.
General guidelines
Some print media might meet all of the guidelines in this manual and still not produce satisfactory
results. This problem might be the result of improper handling, unacceptable temperature and
humidity levels, or other variables over which Hewlett-Packard has no control.
Before purchasing large quantities of print media, always test a sample and make sure that the print
media meets the requirements specified in the HP LaserJet Printer Family Print Media Guide
available at
This printer accepts a variety of media, such as cut-sheet paper (including up to 100% recycled-fibercontent paper), envelopes, labels, transparencies, HP LaserJet glossy paper, HP LaserJet Tough
paper, HP LaserJet Photo paper, and custom-size paper. Properties such as weight, composition,
grain, and moisture content are important factors that affect printer performance and output quality.
Print media that does not meet the guidelines outlined in this manual can cause the following
problems:
http://www.hp.com/support/ljpaperguide.
CAUTION Using print media that does not meet HP specifications can cause problems for
the printer, requiring repair. This repair is not covered by the Hewlett-Packard warranty or
service agreements.
CAUTION Use only paper designed for laser printers. Paper for inkjet printers may damage
the printer.
■ Poor print quality
■ Increased jams
■ Premature wear on the printer, requiring repair
Paper and print media
For print-media specifications, see Media support tables.
Printing and storage environment
Ideally, the printing and media-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.
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 issue 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 and print quality.
14 Chapter 1 Product information ENWW
Page 29
Care should be taken not to purchase more paper than can be easily used in a short time (about
three months). Paper stored for long periods can 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 media-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:
■ Print media should be stored at or near room temperature.
■ The air should not be too dry or too humid (to moderate 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 printer environment is subject to extremes, unwrap only the amount of paper to
be used during the day's operation to prevent unwanted moisture changes.
■ Avoid storing paper and print media near heating and air conditioning vents or near windows and
doors that are frequently open.
Envelopes
Envelopes can be printed from Tray 1 or Tray 2. Select the type of envelope that you are using from
the Print dialog box or the printer driver.
In your program, set the margins for the envelope. The following table gives typical address margins
for a commercial #10 or DL envelope.
Table 1-3 Envelope specifications
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)
■ 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 and creates an air bubble, then the envelope might wrinkle during printing.
Envelope construction
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
ENWW Print-media specifications 15
Page 30
depends upon the quality of the envelopes. When selecting envelopes, consider the following
components:
■
Weight: The weight of the envelope paper should not exceed 90 g/m
2
(24 lb) or jamming might
occur.
■ Construction: Before 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 printer. This
printer fusing temperature is 210°C (410°F).
■ Size: Use only envelopes that are within the following size ranges.
Table 1-4 Envelope size ranges
Tray Minimum Maximum
Tray 1 or Tray 2 76 x 127 mm (3 x 5 inches) 216 x 356 mm (8.5 x 14 inches)
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
Figure 1-8 Envelope double side-seam construction
1 Acceptable
2 Unacceptable
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 that are compatible with the heat and pressure in the printer. The extra flaps and strips
might cause wrinkling, creasing, or even jams and might damage the fuser.
16 Chapter 1 Product information ENWW
Page 31
Labels
Select the type of label that you are using from the Print dialog box or the printer driver.
CAUTION To avoid damaging the printer, use only labels that are recommended for laser
printers. To prevent serious jams, always use Tray 1 or Tray 2 to print on labels. 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 210°C (410°F), which is the printer 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: Before printing, labels must lie flat with no more than 13 mm (0.5 inch) of curl in any
direction.
■ Condition: Do not use labels that have wrinkles, bubbles, or other indications of separation.
Transparencies
Use only Tray 1 or Tray 2 to print on transparencies. Select Transparencies from the Print dialog
box or the printer driver.
The printer supports printing on color transparencies. Use only transparencies that are
recommended for use in laser printers.
Transparencies that are used in the printer must be able to withstand 210°C (410°F), which is the
printer fusing temperature.
CAUTION To avoid damage to the printer, use only transparencies that are recommended
for use in laser printers.

different media than the rest of the document.
ENWW Install input devices 25
Page 40
For information about loading special print media such as envelopes, labels, and transparencies, see
Print-media specifications.
To load Tray 1
1 Media guides ensure that the media is correctly fed into the printer and that the print is not
skewed. Slide the media-width guides slightly wider than the print media.
2 Feed print media into Tray 1 with the side to be printed down, and the top, short edge in first.
Make sure that the media is inserted far enough into the printer for the paper feed mechanism to
grab the media. The paper will reach the sensor after 140 mm (5.5 inches) has been inserted.
The printer will then pause for .5 second before it pulls the paper into the printer. HP
recommends holding the paper on both sides when inserting.
NOTE Light weight paper may buckle if held only on the short (far) edge as it is inserted.
As paper is inserted, it trips the registration shutter. For light weight paper, holding it on
both sides near the slot increases the ability for the paper to appropriately trip this shutter.

The printer automatically calibrates at various times. You can adjust the calibration settings by using
the HP Toolbox.
Environmental differences or aging print cartridges might cause fluctuations in image density. The
printer accounts for this with image stabilization control. The printer automatically calibrates at
various times to maintain the highest level of print quality. You can also request a calibration by using
the HP Toolbox.
The printer does not interrupt a print job to calibrate. It waits until the job is complete before
calibrating or cleaning. While the printer is calibrating, it pauses printing for the time that is required
to complete the calibration.

Image formation system
The image formation system serves as the nerve center of the printer and forms a toner image on
paper. It is controlled by the DC controller. The DC controller controls the laser/scanner unit and the
high-voltage power supply PCB to form an image on paper according to the VIDEO signals (VDO, /
VDO) upon reception of a print command from the formatter. There is a memory tag inside each
cartridge. The memory tags read and write data according to the command from the DC controller.
The following figure illustrates the image formation system.

Image formation process
Figure 4-3 Image formation process
ENWW Image formation system 43
Page 58
The principal process of image formation is described here. The print process can be broadly divided
into 5 stages with 7 steps. A toner image is formed on paper as it goes through each process. The
following figure illustrates the stages and steps of the print process as follows.
1 Electrostatic latent image formation stage
Forms an electrostatic latent image on the photosensitive drum.
Step 1: Primary charging
Step 2: Laser beam exposure
2 Developing stage
Makes the electrostatic latent image on the photosensitive drum surface visible by applying toner.
Step 3: Development
3 Transfer stage
Transfers a toner image on the photosensitive drum onto paper.
Step 4: Transfer
Step 5: Separation
4 Fuser stage
Fuses the toner image on paper.
Step 6: Fuser
5 ETB cleaning stage
Cleans the residual toner on the photosensitive drum.
Step 7: ETB cleaning
Latent image formation
This stage consists of two steps and forms an electrostatic latent image on the photosensitive drum.
When the last step in this stage is completed, a negative electrical charge remains in the unexposed
drum surface area by the laser beam and is removed from the exposed area. The image with
negative charge on the drum is called an “electrostatic latent image” as it is invisible to human eyes.
44 Chapter 4 Operational theory ENWW
Page 59
Figure 4-4 Latent image formation
Laser/scanner system
The laser/scanner system forms latent images on the photosensitive drum according to the VIDEO
signals sent from the formatter. It consists of the laser driver PCB, the scanner motor, and so forth.
The figure below illustrates the laser/scanner unit.
Figure 4-5 Laser beam exposure
Developing stage
The electrostatic latent image on the photosensitive drum surface is visualized by applying the toner
in this process. This printer utilizes the projection development method by the non-magnetic, singlecomponent toner.
ENWW Image formation system 45
Page 60
Figure 4-6 Developing stage
The toner has an insulating property and has negative charge potential from friction with the rotating
developing cylinder and the developing blade surface.
The area of the photosensitive drum, where the laser beam is exposed, has higher potential than the
toner, which is charged negatively on the cylinder. When this area contacts the toner layer
(negatively charged), the toner jumps onto the drum surface by the potential difference between the
drum surface and the cylinder (higher potential on drum side). This is called the projection
development and it visualizes the electrostatic latent image on the drum. The developing cylinder is
applied the AC bias in order to make the toner jump easier onto the drum surface and improve the
contrast of the output image.
This printer is able to adjust the image density by changing the potential difference between the
cylinder and the photosensitive drum surface according to changes of the developing DC bias based
on the IMAGE DENSITY INFORMATION signal sent from the formatter.
The developing sheet improves the print quality and also prevents toner scattering.
Print cartridge
The cartridge forms a visible toner image on the photosensitive drum. There are four print cartridges:
magenta, cyan, yellow, and black; each having identical structure.
46 Chapter 4 Operational theory ENWW
Page 61
Figure 4-7 Print cartridge structure
Transfer belt (ETB)
The ETB unit feeds paper as well as transfers toner onto the paper.
The ETB unit consists of the ETB, ETB feed roller, ETB driven roller, and color misregistration/
density sensor unit.
As the main motor rotates the ETB feed roller, the ETB feed roller rotates the ETB belt. The transfer
roller and the ETB driven roller are engaged with the ETB.
During printing, the picked up paper is conveyed in between the ETB and the photosensitive drum,
and simultaneously the toner image is transferred onto the paper. The ETB is also used for color
misregistration corrective control and the image stabilization control. The pattern image for the color
misregistration or image density determination is transferred onto the belt. This pattern image is read
in the color misregistration/density sensor unit.
The following is the diagrammatic sketch of the ETB unit.
ENWW Image formation system 47
Page 62
Figure 4-8 ETB unit
Transfer stage
The transfer stage is to transfer the toner image on the photosensitive drum surface onto paper.
Figure 4-9 Transfer stage
48 Chapter 4 Operational theory ENWW
Page 63
The toner on the photosensitive drum surface is transferred onto the paper according to the positive
charge from the back side of the paper. Each color’s toner image is transferred in order of M, C, Y,
and K, and forms one toner image overlaying one color’s image on another.
Separation stage
Figure 4-10 Separation stage
The paper is separated from the drum by its elasticity (Curvature Separation). The static charge on
the back side of the paper is decreased with the electrostatic eliminator in order to stablize the
feeding operation and prevent the crescent spots of printing image under the low temperature and
low humidity environment.
Fusing stage
The toner image is fused onto the paper in this stage. The toner image transferred onto the paper
through the transfer stage can be smeared easily by hands since it is only attracted to the paper by
the static electricity. The paper and the toner on it are fused by pressure, fused and secondary
colored by heat to be a permanent image.
Figure 4-11 Fusing stage
The toner image on the paper is fused onto the paper by using the on-demand fuser method in this
step. This printer utilizes the ceramic heater with lower heat capacity, which warms up quickly, does

not require the power supply during STBY mode, and saves energy. As for the printer, the DC
positive bias is applied to the fuser pressure roller, so the transferred toner stays harder on the paper
and toner scattering to the fuser film (offset) is prevented.
50 Chapter 4 Operational theory ENWW
Page 65
Pickup and feed system
The pickup/feed system, which picks up and feeds paper, consists of the various feed rollers. This
printer has two pickup sources: the cassette and the manual feed slot, and one delivery source: the
face-down tray. The following components are part of the pickup and feed system:
■ Manual feed slot paper sensor (SR3): detects the presence of paper in the manual feed slot
■ Cassette paper sensor (SR2): detects the presence of paper in the cassette
■ DC controller controls the following to drive each feed roller:
■ Main motor (M1)
■ Fuser/delivery motor (M2)
■ Pickup motor (M3)
■ Solenoid (SL1)
■ Solenoid (SL2)
■ Solenoid (SL3)
■ Photo sensors:
■ SR1, SR4, and SR5 on the paper transport path detect the arrival and passage of paper
■ SR9 detects the fuser pressure roller alienation in the fuser
■ SR8 detects the paper width
The figure below illustrates the motors, solenoids, and sensors.
NOTE There is a short pause before the paper is picked up.

Manual feed slot pickup mechanism
This mechanism picks up one sheet of paper only that is inserted into the manual feed slot and then
into the printer. This printer does not have a pickup roller in the manual feed slot. Instead of a pickup
roller, the registration roller picks up paper. The presence of paper in the manual feed slot is
detected by the manual feed slot paper sensor (SR3). The following is the operational sequence of
the manual feed slot pickup.
1 If paper is set into the manual feed slot during STBY mode, the manual feed slot paper sensor
(SR3) detects it.
2 When the paper is detected, the DC controller drives the pickup motor (M3) for 5 seconds. The
paper is fed approximately 5 mm (0.2 inch) and is then caught by the registration roller.
3 After the above operational sequence, the paper is fed by the drive of the registration roller.
Paper feed mechanism
This mechanism feeds one sheet of picked up paper to the fuser. There is a paper width sensor in
the paper transport path to prevent temperature rise at the end of the fuser. It detects paper with
widths of shorter than 190 mm (7.5 inches). The following is the operational sequence of paper feed.
1 Paper skew is corrected by the registration shutter when the paper is fed into the printer.
2 Toner is transfered to the paper from the photosensitive drum and then the paper is fed to the
fuser/delivery stage.
Skew correction by the registration shutter
If the paper fed into the printer is skewed, when it hits the registration shutter, it will be adjusted.
Figure 4-13 Skew correction illustrates how skewed paper is corrected by the registration shutter.
ENWW Pickup and feed system 53

Figure 4-13 Skew correction
Jam detection
This printer is provided with the following paper detection sensors to detect the presence of paper
and whether or not the paper feed is operating normally.
■ Registration paper sensor (SR1)
■ Pre-fuser paper sensor (SR5)
■ Fuser delivery paper sensor (SR4)
The CPU determines a paper jam by checking whether or not paper is present at the sensor at the
check timing. The check timing is stored in the memory of the CPU. If the CPU determines a jam, it
stops the print operation and notifies the formatter of a jam occurrence.

Printer calibration
Calibration settings are configured with Printer Management Language (PML)/Printer Job Language
(PJL) commands, except for new cartridge installation. Calibration can also be configured using the
embedded Web server and HP Toolbox. Calibration occurs during the following conditions and
intervals:
■ Power-on calibration
Calibration during power-on can be configured for the following intervals:
■ Always calibrate at power-on
■ Never calibrate at power-on
■ Calibrate after 1-6 minutes (default is 15 minutes) of idle time after the first job since the
printer was turned on or 12, 24, 48, 96, or 168 hours (default is 48 hours) of idle time.
■ Page count calibration
Calibration occurs at the end of the first job that passes 150 color pages since the previous
calibration occurred. Page count calibration settings can be configured for the following intervals:
■ Do not do page count calibrations
■ Calibrate after 150 pages have been printed since the last calibration. This is the default
setting.
NOTE Page count calibration cannot be set using the embedded Web server.
■ Elapsed time calibration
Elapsed time calibration will occur when the first job is sent after the elapsed time is exceeded.
Use PML/PJL commands to configure the following intervals:
■ Do not perform elapsed time calibration
■ After 12, 24, 48, 96, or 168 hours (default is 48 hours) or more have elapsed since the last
calibration (or power-on), and after 1-6 minutes (default is 15 minutes) of idle time from the
first job after 12, 24, 48, 96, or 168 hours (default is 48 hours) have elapsed.
■ On-demand calibration
Calibrate the printer using the printer control panel. For more information about printer
calibration, see
■ New consumable calibration
When a new print cartridge is installed, the printer will calibrate.
NOTE When a new black print cartridge is replaced, a cleaning page will print before the
printer calibrates.
If printing stops when the cartridge is out, requiring the user to either install a new cartridge or
select to print with toner out override, a calibration will not occur until the depleted cartridge is
replaced, printing resumes, and all jobs currently in the queue are finished or cancelled. This
could result in an interval of several pages where a new cartridge is using the old cartridge’s
calibration data.
