Print-media specifications
For optimum results, HP recommends using HP media that is designed for HP Color LaserJet printers.
Use media with a weight between 75 g/m
media with weights between 60 g/m
2
to 120 g/m2 (20 to 32 lb bond). Although the printer supports
2
to 176 g/m2 (16 to 47 lb bond), using lighter or heavier media could
impact the paper-jam rate and the optimal print-quality performance.
Always use the correct media-type setting in the printer driver, and configure the trays for the correct
media type. HP recommends testing any paper before buying it in large quantities.
Supported paper and print media sizes
This product supports a number of paper sizes, and it adapts to various media.
NOTE: To obtain best print results, select the appropriate paper size and type in your print driver before
printing.

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. The HP Color
LaserJet 3000 and HP Color LaserJet 3800 use DDR memory. The CP3505 Series printers use DDR2
memory.
More printer memory DIMMs are available in 128, 256, 512 MB , and 1 GB (CP3505 Series printers
●
only) 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
Using printer information pages on page 40.
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.
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.

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

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.
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.
http://www.hp.com/go/
Checking the supply level
You can check the toner-supply level by using the control panel, the embedded Web server, or
HP Web Jetadmin.

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

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 print-quality 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.

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.

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 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.
NOTE: Tray 2 must be installed in order to print from tray 1 or tray 3.

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
Page 68
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

The following jams can occur during operation:
Pick-up delay jam. The printer makes three attempts to pick up media from a tray. When the top-
●
of-page sensor (SR710) does not detect the leading edge of a page within a specific time after the
third attempt, the printing operation stops. The time varies depending on the printer model and the
media source, as follows.
HP CLJ 3000: 1.3 seconds from the cassette; 2.2 seconds from the multipurpose tray (tray 1); 2.3
seconds from the paper feeder

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 61
Page 74
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
62 Chapter 4 Theory of operation ENWW
Page 75
These processes are divided into ten steps, which are shown in Figure 4-10 Image-formation steps
on page 63 and described in the following sections.
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.
ENWW Image-formation system 63
Page 76
Step 1: pre-exposure
The pre-exposure LED hits the photosensitive drum surface and eliminates any residual charge on the
surface.
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.
64 Chapter 4 Theory of operation ENWW
Page 77
Transfer stage
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
ENWW Image-formation system 65
Page 78
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.
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
66 Chapter 4 Theory of operation ENWW
Page 79
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.
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
●
Developer roller engagement and disengagement control
●
ENWW Image-formation system 67
Page 80
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).
