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.

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.

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
www.hp.com/go/webjetadmin/.

Job-storage features

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.

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

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
Managing the print cartridge 65

Checking the supply level

You can check the supply (toner) level by using the control panel, the embedded Web server, HP Toolbox software, or HP Web Jetadmin.

which provides supply-level information.
To check the supply level by using the HP Toolbox software
You can configure HP Toolbox to notify you when the print cartridge is low. You can choose to 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.

for
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 message remains until you replace the print cartridge. If CARTRIDGE OUT is set to STOP, the MFP stops printing until you replace the print cartridge or resume printing by configuring the MFP to continue: In the CONFIGURE DEVICE menu, under SYSTEM SETUP, set CARTRIDGE OUT to CONTINUE.
When the drum life of the print cartridge is out. You must replace the print cartridge to
continue printing. No override is possible, even if toner remains in the cartridge. (See
