Printer memory

NOTE: This information applies to the HP Color LaserJet 3000, 3800, and CP3505 Series

printers only.

The HP Color LaserJet 3000, 3800, and CP3505 Series printers have one DIMM slot.

More printer memory DIMMs are available in 128, 256, and 512 MB increments.

●

Other DIMM-based printer languages and printer options are available.

●

NOTE: Single in-line memory modules (SIMMs) that are used on previous HP LaserJet

printers are not compatible with these printers.

You might want to add more memory to the printer if you often print complex graphics or PostScript documents, if you use many downloaded fonts, or if a Jetdirect EIO print server will be installed for network printing capabilities. Additional memory also allows the printer to print multiple collated copies at the maximum speed.

Before ordering additional memory, see how much memory is currently installed by printing a configuration page. See

Installing memory DIMMs

You can install more memory for the printer, and you can also install a font DIMM to print characters for languages such as Chinese or the Cyrillic alphabet.

Using printer information pages on page 40.

CAUTION: Static electricity can damage DIMMs. When handling DIMMs, either wear an

antistatic wrist strap or frequently touch the surface of the DIMM antistatic package and then touch bare metal on the printer.

To install memory DIMMs

1. Turn the printer off, and then disconnect all power and interface cables.

26 Chapter 2 Installation and configuration ENWW

2. On the right side of the printer, gently pull the black tabs together, and then pull the formatter

assembly from the printer.

3. Place the formatter board on a clean, flat, grounded surface.

To replace a DIMM that is currently installed, spread the latches apart on each side of the DIMM slot, lift the DIMM up at an angle, and pull it out.

Replacing supplies

When you use genuine HP supplies, the printer automatically notifies you when supplies are nearly depleted. The notification to order supplies allows ample time to order new supplies before they need to be replaced.

Locating supplies

Supplies are identified by their labeling and their blue plastic handles.

The following figure illustrates the location of the print cartridges.

Figure 3-1 Supply-item locations

1 Print cartridges

Supply replacement guidelines

To facilitate the replacement of supplies, keep the following guidelines in mind when setting up the printer.

Allow sufficient space above and in the front of the printer for removing supplies.

●

Place the printer on a flat, sturdy surface.

●

For instructions about installing supplies, see the installation guides that came with each supply item, or see more information at

http://www.hp.com/support/clj3800, or http://www.hp.com/support/cljcp3505. When you connect,

select Troubleshoot a Problem.

CAUTION: Hewlett-Packard Company recommends the use of genuine HP products in this

printer. Use of non-HP products might cause problems requiring service that is not covered by the Hewlett-Packard extended warranty or service agreements.

http://www.hp.com/support/clj3000, http://www.hp.com/support/clj3600,

ENWW Replacing supplies 33

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

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 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.

34 Chapter 3 Maintenance ENWW

Checking the supply level

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

Using the control panel

1. Press Menu to open the MENUS.

Press

to highlight PRINT SUPPLIES STATUS.

Using the embedded Web server

1. In your browser, type the IP address for the printer home page. This takes you to the printer

status page.

2. On the left side of the screen, click Supplies Status. This takes you to the supplies status page,

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.

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 site at

ENWW Managing the print cartridge 35

http://www.hp.com/go/recycle.

To replace the print cartridge

1. Open the front cover and ETB unit.

CAUTION: Do not place any item on the transfer unit while it is open. If the transfer unit

is punctured, print-quality problems could result.

2. Remove the used print cartridge from the printer.

36 Chapter 3 Maintenance ENWW

3. Remove the new print cartridge from the bag, and remove the tape-seal. Place the used print

cartridge in the bag for recycling.

4. Align the print cartridge with the tracks inside the printer and insert the cartridge until it is

completely seated.

NOTE: Use the blue cartridge handles when installing the new cartridge in the printer.

Touching other areas of the print cartridge can damage the image drum and cause printquality defects.

NOTE: If a cartridge is in the wrong slot, the message INCORRECT COLOR

CARTRIDGE appears on the control panel.

5. Close the front cover and then close the top cover. After a short while, Ready appears on the

control panel.

6. Installation is complete. Place the used print cartridge in the box that the new cartridge came in.

See the enclosed recycling guide for recycling instructions.

7. If you are using a non-HP print cartridge, check the control panel for further instructions.

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

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

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

specifications on page 38.

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).

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 57

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. When the media reaches SR708, motor M4 stops, the MP tray media sensor detects the media,

and then motor M4 restarts and resumes feeding media into the printer.

Figure 4-8 Multipurpose-tray pickup mechanism

Feed-speed control

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

NOTE: In the following table, normal speed is 22 ppm for the HP CLJ 3800 and CP3505

models, and normal speed is 18 ppm for the HP CLJ 3600 models. Normal speed is 30 ppm for the HP CLJ 3000 model (black mode only).

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 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 63

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 65 and described in the following sections.

Figure 4-10 Image-formation steps

64 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 65

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

66 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. Negatively charged media attracts 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 beam strength or stiffness of media combined with the ETB holding force causes the media to separate from the drum. The sheet remains on the ETB and continues to travel through the printer.

ENWW Image-formation system 67

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.

68 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 imageformation 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

●

Developer roller engagement and disengagement control

●

ENWW Image-formation system 69

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 ESDprotected 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 field-replaceable 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.

●
