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 this user guide and in the HP LaserJet Printer Family Print Media Guide.
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.
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:
Poor print quality
Increased jams
Premature wear on the printer, requiring repair

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 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.
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 recommended 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.
10 Chapter 1 Printer basics ENWW
In your program, set the margins for the envelope. The following table 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)
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 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, stuck together, or otherwise damaged.
Never use envelopes that have clasps, snaps, windows, coated linings, self-stick adhesives, or other synthetic materials.
Temperature: Use envelopes that are compatible with the heat and pressure of the printer. This
printer's fusing temperature is 210°C (410°F).
Size: Use only envelopes that are within the following 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 indicated in the following illustration.
ENWW Print-media specifications 11
1
2
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.
CAUTION Failure to follow the guidelines above can result in jams.
For instructions on loading envelopes, see Loading Tray 1 on page 21 or Loading Trays 2 and 3
on page 23.

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, other indications of separation, or are
damaged in any way.
For instructions on loading labels, see
on page 23.

Managing supplies

For warranty information about these supplies, see Print Cartridge Limited Warranty Statement
on page 235.

Supplies life

The life of a print cartridge depends on the amount of toner that print jobs require. When printing text at approximately 5% coverage, a cyan, magenta, or yellow print cartridge for the HP Color LaserJet 2605 Series printers lasts an average of 2,000 pages, and a black print cartridge lasts an average of 2,500 pages. A typical business letter has 5% coverage.

Checking and ordering supplies

You can check the supplies status by using the printer control panel, printing a Supplies Status page, or viewing the HP ToolboxFX. Hewlett-Packard recommends that you place an order for a replacement print cartridge when you first receive the Low message for a print cartridge. For typical use, the Order message indicates that approximately two weeks of life remain. When you use a new, authentic HP print cartridge, you can obtain the following types of supplies information:
Amount of toner remaining
Estimated number of pages remaining
Number of pages printed
Other supplies information
NOTE If the printer is connected to the network, you can set the HP ToolboxFX to notify you
by e-mail when a print cartridge is low or is near the end of its useful life. If the printer is directly connected to a computer, you can set HP ToolboxFX to notify you when supplies are low.
To check status and order using the control panel
Do one of the following:
Check the supplies status gauges on the printer control panel. These gauges indicate when a
print cartridge is low or empty. The lights also indicate when a non-HP print cartridge is first installed.
To print the Supplies Status page from the printer, on the printer control panel, select Reports
Menu, and then Supplies Status. See
If the supplies levels are low, you can order supplies through your local HP dealer, by telephone, or online. See the HP Color LaserJet 2605, 2605dn, 2605dtn User Guide for part numbers. See

HP policy on non-HP supplies

Hewlett-Packard Company cannot recommend the use of non-HP supplies, either new or remanufactured. Because they are not HP products, HP cannot influence their design or control their quality. Service or repairs required as a result of using a non-HP supply will not be covered under the printer warranty.
When you insert a supply into the printer, the printer will inform you if the supply is not a genuine HP supply. If you insert a genuine HP supply that has reached the low state from another HP printer, the printer identifies the supply as non-HP. Simply return the supply to the original printer to reactivate HP features and functionality.
Resetting the printer for non-HP supplies
When you install a non-HP print cartridge, the light next to the print cartridge you replaced blinks and the Attention light is on. In order to print with this supply, you must press
install this non-HP supply. The status gauges will not indicate when this type of supply is low or empty.
CAUTION The printer will not stop printing when this type of supply is empty. Printer
damage could occur if the printer prints with an empty print cartridge. See Hewlett-Packard
limited warranty statement on page 234 and Print Cartridge Limited Warranty Statement on page 235.

Cartridge out override

What is it?
The HP Color LaserJet 2605 Series printers display an ORDER SUPPLIES message when a cartridge is running low and a REPLACE SUPPLIES message when a cartridge has been depleted. To ensure optimal print quality, HP recommends replacing a cartridge when the REPLACE SUPPLIES message is displayed. Replacing the cartridge at this point can help prevent waste of media or other cartridges when one cartridge produces poor print quality.
The Cartridge Out Override feature allows the printer to continue using a cartridge that has reached the recommended replacement point.
WARNING! Using Override may result in unsatisfactory print quality and unavailability of
certain features (such as toner remaining information).
WARNING! All print defects or supply failures incurred when an HP supply is used in
Override will not be considered defects in materials or workmanship in the supply under HP's Print Cartridge Limited Warranty Statement. For Warranty information, see Print Cartridge
Limited Warranty Statement on page 235.

The operational sequence of the printer is controlled by the microcomputer on the DC controller printed circuit assembly (PCA). The purposes of each period, from power-on until the main motor stops after the completion of printing, are listed below. See detailed timing chart.
Table 4-1 Basic operational sequence
Period Purpose Remarks
General timing chart on page 80 for a
WAIT (wait period) From power-on until the end
of the main motor initial drive.
STBY (standby period) From the end of WAIT or
LSTR until the input of print command from the formatter. Or, from the end of LSTR until power-off.
INTR (initial rotation period) From the input of print
command from the formatter until the pick-up solenoid is turned on.
PRINT (print period) From the end of INTR until
the developing high-voltage is off.
LSTR (last rotation period From the developing high-
voltage off until the main motor stops rotating.

The interval of the MAIN MOTOR SPEED DETECTION signal (/MAINMFG) does not become the specified interval after 1000 ms of the main motor drive start.
Main motor rotation abnormality
The interval of the /MAINMFG signal stays at an irregular interval for 100 ms and longer after once it has become the specified interval.
Fan motor failure detection
The CPU determines the fan motor failure and notifies the formatter when it encounters the following condition.
The FAN LOCK signal (FANLCK) is “H” for approximately 10 seconds and longer during fan motor rotation.
58 Chapter 4 Operational theory ENWW

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 PCA 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.
ENWW Image formation system 59
Figure 4-2 Image formation system
60 Chapter 4 Operational theory ENWW

Image formation process

Figure 4-3 Image formation process
ENWW Image formation system 61
The principal process of image formation is described here. The print process can be broadly divided into five stages with seven 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”, and it is invisible to the human eye.
62 Chapter 4 Operational theory ENWW
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 PCA, 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 63
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 from scattering.
Print cartridge
The cartridge forms a visible toner image on the photosensitive drum. There are four print cartridges: magenta (M), cyan (C), yellow (Y), and black (K).
64 Chapter 4 Operational theory ENWW
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 65
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
66 Chapter 4 Operational theory ENWW
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 transferred onto the paper through the transfer stage can be smeared easily because it is only attracted to the paper by the static electricity. In the fusing stage, the printer used heat and pressure to make the image permanent.
Figure 4-11 Fusing stage
The toner image 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. The printer applies the DC positive bias to
ENWW Image formation system 67
the fuser pressure roller so that the transferred toner stays on the paper and toner scattering (offset) is prevented.
68 Chapter 4 Operational theory ENWW

Pickup and feed system

The pickup and feed system, which picks up and feeds paper, consists of the various feed rollers. This printer has two pickup sources: the cassette and the single-sheet priority 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 single-sheet priority
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

Manual feed slot pickup mechanism

This mechanism picks up one sheet of paper only that is inserted into the single-sheet priority feed slot and then into the printer. This printer does not have a pickup roller in the single-sheet priority feed slot. Instead of a pickup roller, the registration roller picks up paper. The presence of paper in the single-sheet priority feed slot is detected by the single-sheet priority feed slot paper sensor (SR3). The following is the operational sequence of the single-sheet priority feed slot pickup.
1. If paper is set into the single-sheet priority feed slot during STBY mode, the single-sheet priority
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, it will be adjusted when it hits the registration shutter.
Figure 4-13 Skew correction on page 72 illustrates how the registration shutter corrects skewed
paper.
ENWW Pickup and feed system 71
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.

Duplexing mechanism

The duplexing mechanism feeds paper to the reversing unit after the first side is printed, and then it returns the paper to the duplexing feed unit so that the print side of the paper is reversed for second­side printing.
The duplexing driver controls the duplexing feed motor (M6) and the reverse motor (M7), which drives each feed roller of the duplexing feed unit. It also controls the reverse solenoid (SL5), which drives the duplexing deflector.
The top cover can be opened to remove jams in the reverse unit. The top cover open sensor (SR7) is used for open/close detection. After clearing a jam in the duplexing mechanism, open the front door to make sure there are no jams in other areas.
The paper path is shown in reverse motor, solenoid, and sensor are shown in

The operational sequence of duplex printing is as follows:
1. The duplexing driver activates the reverse solenoid (SL5) to drive the duplexing deflector when
the leading edge of paper arrives at the fixing unit. It then rotates the reverse motor (M7) clockwise and feeds the paper to the reverse unit.
2. The duplexing driver stops the reverse motor and turns off the reverse solenoid after the trailing
edge of the paper passes through the fixing delivery paper sensor.
3. The duplexing driver rotates the reverse motor counter-clockwise to feed the paper to the
duplexing feed unit. It turns on the duplexing feed motor (M6) after a specified time to feed the paper to the duplexing pick-up position. The oblique roller corrects skew and makes sure that edge of the paper is flush with the left guide.
4. If the duplexing driver has received the duplexing pick-up command, the paper is fed to the
registration roller. If it has not, the paper is stopped and is fed to the registration roller when the command is received.
5. The second side of the paper is printed and fed to the delivery tray.
78 Chapter 4 Operational theory ENWW
Figure 4-19 Duplexing components
If paper fed from the duplexing pick-up position does not arrive at the registration sensor within a prescribed period of time, the DC controller stops the printing operation and notifies the video controller of a duplexing pick-up jam.

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 ToolboxFX. 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 calibrates.
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 completed or cancelled. This could result in an interval of several pages where a new cartridge is using the old cartridge’s calibration data.
