Managing the print cartridge

This section provides information about HP print cartridges, including 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:

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 printer warranty.

When you use a non-HP print cartridge, certain features, such as remaining toner-volume data, might
not be available.

Using genuine HP supplies ensures the availability of all HP printing features.

Print-cartridge authentication

A message appears on the printer control-panel display if you insert a print cartridge that is not a genuine
HP print cartridge. 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 correct 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. 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.

ENWW Managing the print cartridge 33

Checking the supply level

You can check the toner-supply level by using the control panel, the embedded Web server, or

which provides print-cartridge information.

Using HP Web Jetadmin

In HP Web Jetadmin, select the printer. The device status page shows print-cartridge information.

Replacing print cartridges

When a print cartridge approaches the end of its useful life, a message to order a replacement appears
on the control-panel display. The printer can continue to print with the current print cartridge until the
control-panel message instructs you to replace the cartridge.

The printer uses four colors, each in its own and has a different print cartridge: black (K), magenta (M),
cyan (C), and yellow (Y).

Replace a print cartridge when a REPLACE <COLOR> CARTRIDGE message appears on the printer
control panel. The control-panel display indicates the color that should be replaced (if a genuine
HP cartridge is currently installed).

CAUTION If toner gets on clothing, wipe it off with a dry cloth and wash the clothes in cold

water. Hot water sets toner into fabric.

NOTE For information about recycling used print cartridges, visit the HP LaserJet Supplies Web

Cleaning the printer

Clean the outer surfaces with an HP Toner Cleaning Cloth or a water-dampened cloth.

WARNING! Before you begin these steps, turn the printer off and unplug all power cords to

avoid shock hazard. Be careful when cleaning around the fuser area. It might be hot.

CAUTION To avoid permanent damage to the print cartridge, do not use ammonia-based

cleaners on or around the printer. If toner gets on your clothes, wipe it off with a dry cloth and
wash your clothes in cold water. Hot water sets toner into fabric.

Component Cleaning Method

Outer covers Use an HP Toner Cleaning Cloth (part number 5090-3379) or

Inside, general With a dry, lint-free cloth, wipe any dust, spilled toner, and

ETB attaching roller Clean with lint-free paper. If dirt cannot be removed, dampen

Paper-pickup rollers Clean with lint-free paper. If dirt cannot be removed, dampen

a water-dampened cloth. Do not use solvents or ammonia­based cleaners.

the paper with alcohol.

Cleaning spilled toner

Defective print cartridges can develop leaks. Also, after a jam has occurred, some toner might remain
on the rollers and guides inside the printer. The pages that print immediately after the jam can pick up
this toner. Use a vacuum that is designed for picking up fine particles. See

on page 37.

CAUTION When cleaning the printer, do not touch the ETB with the damp cloth or with your

fingers.

Vacuum specifications

Do not use a conventional vacuum to vacuum the printer or any spilled toner. The toner particles used
in this product might be too fine for effective vacuuming and could result in damage to conventional
vacuums.

You can use a vacuum specifically designed for cleaning if it can filter fine particles (5 microns in
diameter).

Laser/scanner system

The formatter sends video signals to the DC controller, which controls the laser/scanner. When the laser/
scanner system receives those signals it converts them to latent images on the photosensitive drum.

Figure 4-4 Laser/scanner system

52 Chapter 4 Theory of operation ENWW

Pickup-and-feed-system

The pickup and feed system consists of several types of feed rollers and sensors.

The DC controller drives the system by controlling the feed motor (M4), ETB motor (M5), and four drum
motors (M6, M7, M8, M9) and the solenoids for the trays. In models that include an automatic duplex
accessory, the duplexing feed motor (M10) and reversing motor (M11) are also part of the system.

Sensors in the pickup-and-feed system trays (cassettes)

Paper sensors detect media in the trays. Other sensors react to the media as it moves through the paper
path. If the 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. In models that include an automatic duplex
accessory, the paper path contains additional sensors that detect movement through the duplex path.

When the cassette is correctly installed, SW2 detects its presence. The cassette paper sensor (SR709)
detects whether media is present in the cassette, and the cassette media sensor detects the type of
media. When the cassette is correctly installed and the correct media type is present, the cassette pickup
operation begins.

1. The DC controller receives a print command from the formatter, and then begins rotating the pickup-

and-feed motor (M4) at the correct speed for the media type.

2. After the motor reaches the correct speed and the fuser is at the correct temperature, the cassette

pickup solenoid (SL5012) turns on and the cassette pickup roller begins rotating.

3. The cassette lifting plate lifts the paper stack, and the cassette pickup roller picks up one sheet of

media. The separation pad prevents multi-feeds.

Figure 4-7 Cassette pickup mechanism

ENWW Pickup-and-feed-system 55

Multipurpose-tray pickup mechanism

The cassette must be installed in order for the multipurpose (MP) tray to operate. The MP tray paper
sensor (SR707) detects whether media is present in the MP tray. When the cassette is correctly installed
and media is present, the MP tray pickup operation begins.

1. The DC controller receives a print command from the formatter, and then begins rotating the pickup-

and-feed motor (M4) at the correct speed for the media type.

2. After the motor reaches the correct speed and the fuser is at the correct temperature, the MP pickup

solenoid (SL5013) turns on and the MP pickup roller begins rotating.

3. The MP pickup roller picks up one sheet of media. The separation pad prevents multi-feeds.

4. The MP tray media sensor detects the media type as the media enters the printer.

Feed-speed control

To optimize print quality, the pickup-and-feed motor rotates at different speeds depending on the type
of media.

Image-formation system

The image-formation system, which forms a toner image on media, consists of several interdependent
systems:

Electrostatic latent-image-formation

●

Developing

●

Transfer

●

Fuser

●

Drum cleaning

●

The printer includes four print cartridges that contain the toner than is used to create the image on the
media. Toner is applied in the following order, using only the colors necessary for a specific image:
magenta (M), cyan (C), yellow (Y), and black (Bk).

Figure 4-9 Image formation system

ENWW Image-formation system 61

Image-formation process

Laser printing requires the interaction of several different technologies including electronics, optics, and
electrographics to provide a printed page. Each process functions independently and must be
coordinated with the other processes. Image formation consists of the following five processes:

1. Latent-image formation

2. Developing

3. Image transfer

4. Fusing

5. Transfer-belt cleaning

These processes are divided into ten steps, which are shown in

on page 63 and described in the following sections.

Figure 4-10 Image-formation steps

62 Chapter 4 Theory of operation ENWW

Figure 4-10 Image-formation steps

Latent-image formation stage

During the three steps that comprise this stage, a latent image is formed by applying a negative charge
to the photosensitive drum. You cannot see this image on the drum.

Step 1: pre-exposure

The pre-exposure LED hits the photosensitive drum surface and eliminates any residual charge on the
surface.

ENWW Image-formation system 63

Figure 4-11 Pre-exposure

Step 2: primary charging

A high-voltage dc bias is applied to the primary charging roller, which is made of conductive rubber and
is in contact with the drum surface. As the roller moves across the drum, it applies the negative charge
to that surface.

Step 3: laser-beam exposure

The laser beam scans the photosensitive drum to neutralize the negative charge on portions of the drum
surface. An electrostatic latent image is formed where the negative charge was neutralized.

Figure 4-12 Laser-beam exposure

Developing stage

The developing cylinder comes in contact with the photosensitive drum and deposits toner on the
electrostatic latent image.

Step 4: developing

Toner acquires a negative charge as a result of the friction from the developing cylinder rotating against
the developing blade. When the negatively charged toner comes in contact with the drum, it adheres to
the electrostatic latent image. When the toner is on the drum the image becomes visible.

Transfer stage

64 Chapter 4 Theory of operation ENWW

Step 5: media feed

The printer generates electrostatic force to pull a sheet of print media to the ETB. The sheet adheres to
the belt and travels between the ETB engaged motor and the attraction roller.

The attraction roller transfer positive dc bias to the media so that the negatively charged toner can be
easily transferred from the drum to the sheet.

Figure 4-13 Media feed

Step 6: image transfer

The ETB carries the positively charged media over the photosensitive drum. As it passes between the
transfer roller and the drum, the transfer roller applies a positive dc bias to the belt. The negatively
charged media and belt attract the negatively charged toner from the drum surface. This process is
repeated for each toner color.

Figure 4-14 Image transfer

Step 7: separation from the drum

The elasticity of the print media causes it to separate from the drum surface. The sheet remains on the
ETB and continues to travel through the printer.

ENWW Image-formation system 65

Figure 4-15 Separation from the drum

Step 8: separation from the ETB

The elasticity of the print media causes it to separate from the ETB. The static-charge eliminator is not
involved during this step.

Fusing stage

Until the fusing stage is complete, the image is not permanently affixed to the print media. The toner
can be easily smudged until the heat and pressure of the fusing process fix the image to the sheet.

Step 9: fusing

The printer uses a ceramic heater to accomplish the color-on-demand fusing process. The heater has
a low heat capacity, which results in a short warm-up period and yields energy savings.

Figure 4-16 Fusing

Cleaning stage

Not all of the toner is removed from the photosensitive drum during the transfer stage. During the
cleaning stage, the residual, or waste, toner is cleared from the drum surface to prepare the surface for
the next latent-image formation.

66 Chapter 4 Theory of operation ENWW

Step 10: drum cleaning

The cleaning blade scrapes the residual toner off the surface of the photosensitive drum and deposits
it in the waste-toner container. The drum is now clear, and is ready for the next image-formation process.

Print cartridge

This printer has four print cartridges: magenta (M), cyan (C), yellow (Y), and black (Bk). Each cartridge
holds non-magnetic, single-component toner that is composed of resins in the four colors.

In addition to the toner, each cartridge contains a developing cylinder, toner-feed roller, and stirrer. The
developer motor rotates these parts so that each print cartridge can deposit toner to form a visible image
on the photosensitive drum.

Figure 4-17 Print cartridge

The cartridges in this printer include the photosensitive drum, the primary charging roller, and the
developing roller. Each cartridge performs these functions:

Memory tag control

●

Cartridge presence detection

●

Developing roller engagement and disengagement control

●

ENWW Image-formation system 67

Print-cartridge activation

A memory tag is a nonvolatile memory that is built into the print cartridge. The DC controller reads and
writes data that is stored in the memory tag. The DC controller reads data at the following times:

When the power is turned on

●

When someone closes the front cover

●

When it receives a command from the formatter

●

The DC controller writes information at the following times:

At a specified interval during printing

●

When it receives a command from the formatter

●

When the read/write operation fails or the wrong data is read or written, the DC controller determines
that an error has occurred and notifies the formatter of a cartridge-memory abnormality. Printing then
stops.

Removal and replacement strategy

Introduction

This chapter describes the removal and replacement of field-replaceable units (FRUs) only.

Replacing FRUs is generally the reverse of removal. Occasionally, notes are included to provide
directions for difficult or critical replacement procedures.

HP does not support repairing individual subassemblies or troubleshooting to the component level.

WARNING! Turn the printer off, wait 5 seconds, and then remove the power cord before

attempting to service the printer. If this warning is not followed, severe injury can result, as well
as damage to the device. The power must be on for certain functional checks during
troubleshooting. However, the power supply should be disconnected during parts removal.

Never operate or service the printer with the protective cover removed from the laser/scanner
assembly. The reflected beam, although invisible, can damage your eyes.

The sheet-metal parts can have sharp edges. Be careful when handling sheet-metal parts.

CAUTION Some parts are sensitive to electrostatic discharge (ESD). Look for the

ESD reminder when removing printer parts. Always perform service work at an ESD-protected
workstation or mat. If an ESD workstation or mat is not available, ground yourself by touching
the sheet-metal chassis before touching an ESD-sensitive part.

Protect the ESD-sensitive parts by placing them in ESD pouches when they are out of the printer.

CAUTION Do not bend or fold the flat flexible cables (FFCs) during removal or installation.

NOTE To install a self-tapping screw, first turn it counterclockwise to align it with the existing

thread pattern, and then carefully turn it clockwise to tighten. Do not overtighten. If a self-tapping
screw-hole becomes stripped, repair the screw-hole or replace the affected assembly.

The printer shown in this chapter is a duplex model. It has a duplex fan mounted to the front
cover, a duplex-feed-drive assembly, and a duplexing-reverse-drive assembly mounted under
the upper (top) cover. Simplex model printers do not have these parts.

The electrostatic transfer belt (ETB) shown in this chapter is for the duplex model printer. The
ETB for the simplex model looks different.

Service approach

Printer repair normally begins by using the printer internal diagnostics and the following two-step
process:

1. Isolate the problem to the major system (for example, the network or server, or the printer).

2. Troubleshoot the problem by using the procedures in chapter 6.

After a faulty part is located, the printer can usually be repaired at the assembly level by replacing field­replaceable units (FRUs). Some mechanical assemblies might need to be repaired at the subassembly
level. Hewlett-Packard Company does not support replacement of components on the printed circuit
assembles.

Before performing service

Remove all media.

●

Unplug the power cable.

●

Place the product on an ESD mat (if available).

●

Remove the print cartridges.

●

Remove the tray 2 cassette.

●

After performing service

Return all media to the trays.

●

Plug in the power cable.

●
