Extended warranty
In most countries/regions, HP Care Pack provides additional coverage, beyond standard
warranty, for the HP device and for all HP-supplied internal components. This hardware
maintenance can uplift the standard warranty, for example, from next-day to same-day
service, and/or extend it up to 5 years. HP Care Pack can also provide Express Exchange or

appropriate phone numbers and information.
ENWW Extended warranty 17
Print-cartridge information
The print cartridge is designed to simplify replacement of the major consumable parts. The
print cartridge contains the printing mechanism and a supply of toner.
At 5-percent page coverage, a standard print cartridge will print approximately 2,000 pages.
As the percentage of toner coverage on the page increases, the number of pages that can be
printed from a standard print cartridge decreases. These estimates are only approximate;
usage conditions and print patterns can cause results to vary.
Refilled print cartridges
While Hewlett-Packard does not prohibit the use of refilled print cartridges during the warranty
period or while the product is under a maintenance contract, it is not recommended for the
following reasons:
● Repairs resulting from the use of refilled cartridges are not covered under Hewlett-Packard
warranty or maintenance contracts.
● Hewlett-Packard has no control or process to ensure that a refilled cartridge functions at
the high level of reliability of a new HP LaserJet toner cartridge. Hewlett-Packard also
cannot predict the long-term reliability effect on the product from using different toner
formulations found in refilled cartridges.
● The print quality of HP LaserJet print cartridges influences customer perception of the
product. Hewlett-Packard has no control over the actual print quality of a refilled cartridge.
● Parts that are critical to print quality might not be replaced when the cartridge is refilled
with toner.
HP LaserJet printing supplies
In many countries/regions, this product's printing supplies (for example the print cartridge) can
be returned to HP through the HP Printing Supplies Returns and Recycling Program. An
easy-to-use and free take-back program is available in more than 30 countries/regions.
Multilingual program information and instructions are included in every new HP LaserJet print
cartridge and supplies package.
HP Printing Supplies Returns and Recycling Program information
Since 1990, the HP Printing Supplies Returns and Recycling Program has collected millions
of used LaserJet print cartridges that otherwise might have been discarded in the world's
landfills. The HP LaserJet print cartridges and supplies are collected and bulk shipped to our
resource and recovery partners, who disassemble the cartridges. Remaining materials are
separated and converted into raw materials for use by other industries to make a variety of
useful products.
U.S. returns
For a more environmentally responsible return of used cartridges and supplies, HP
encourages the use of bulk returns. Simply bundle two or more cartridges together and use
the single, pre-paid, pre-addressed UPS label that is supplied in the package that the new
cartridge comes in. For more information in the U.S., call (1) (800) 340-2445 or visit the HP
LaserJet Supplies website at http://www.hp.com/recycle.

38 Chapter 2 Operation ENWW
Guidelines for using media
Use the information in this section to choose the proper print media.
Paper and transparencies
Paper must be of good quality and free of cuts, nicks, tears, spots, loose particles, dust,
wrinkles, holes, and curled or bent edges. Check the label on the paper package for details
about the type of paper (such as bond or recycled).
Some paper causes print-quality problems, jamming, or damage to the printer.
Note
Do not use letterhead that is printed with low-temperature inks, such as those used in some
types of thermography; raised letterhead; or colored paper or preprinted forms that use inks
incompatible with the printer temperature (200° C, or 392° F, for 0.1 second).
Transparencies must be able to withstand 200° C (392° F), the printer's maximum
temperature.

ENWW Guidelines for using media 39
Labels
Note
For best results, use only HP-brand labels. To order HP supplies, visit http://www.hp.com.
When selecting labels, consider the quality of the following factors:
● Adhesives: The adhesive material should be stable at 200° C (392° F), the products
maximum temperature.
● Arrangement: Use only labels that have no exposed backing between them. Labels can
peel off sheets that have 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, or other indications of
separation. Never use a sheet of labels that has already been run through the device.
Envelopes
When selecting envelopes, consider the quality of the following factors.
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 on the quality of the envelopes, which includes the following factors:
●
Weight: The weight of the envelope paper should not exceed 105 g/m
might result.
2
(28 lb), or jamming
● Construction: Before printing, envelopes should lie flat with less than 6 mm (0.25 inch)
curl and should not contain air. Envelopes that trap air might cause problems.
● Condition: Make sure that the envelopes are not wrinkled, nicked, or otherwise
damaged.
● Sizes: Supported envelope sizes range from 90 by 160 mm (3.5 by 6.3 inches) to 178 by
254 mm (7 by 10 inches).
40 Chapter 2 Operation ENWW
Envelopes with double-side seams
An envelope with double-side-seam construction has vertical seams at both ends of the
envelope rather than diagonal seams. This style is more likely to wrinkle during printing. Make
sure that the seam extends all the way to the corner of the envelope as shown in the following
illustration:
Figure 2-6.
Note
Envelope construction
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 device (200° C or
392° F). The extra flaps and strips might cause wrinkling, creasing, or jams.
Envelope storage
Proper storage of envelopes contributes to good print quality. Store envelopes flat to ensure
good print quality. If air is trapped in an envelope, creating an air bubble, the envelope might
wrinkle during printing.
Card stock and heavy media
Some card stock performs better than others because the construction is better suited for
feeding through a laser device. For optimum device performance, do not use media heavier
than 157 g/m
media jams, poor toner fusing, poor print quality, or excessive mechanical wear.
You might be able to print on heavier media if you do not fill the input trays to capacity and if
you use media with a smoothness rating of 100 to 180 Sheffield.

[8.5 by 14 inches]). Subsequent sheets of legal-size media slide off of the ADF output bin.
Card stock guidelines
Set margins at least 2 mm ( 0.08 inch) away from the edges.
42 Chapter 2 Operation ENWW
Loading media
This section provides information about loading media in the input trays.
Media input tray
The media input tray holds up to 150 sheets of 60-g/m2 (16-lb) paper or a 25-mm (0.98-inch)
stack of heavier media. Load media with the top forward and the side to be printed on facing
up. To prevent jams and skew, always adjust the side media guides.
Priority input tray
The priority input tray holds up to 10 pages of 75-g/m2 (20-lb) paper or one envelope,
transparency, or card. Load media with the top forward and the side to be printed on facing
up. To prevent jams and skew, always adjust the side media guides.
If you try to print on media that is wrinkled, folded, or damaged in any way, a jam might occur.
See the user guide on the product CD for more information.
Note
Note
When you add new media, make sure that you remove all of the media from the input tray and
straighten the stack of new media. This helps prevent multiple sheets of media from feeding
through the printer at one time, reducing jams.
Specific types of media
● Transparencies and labels: Load transparencies and labels with the top forward and the
side to be printed on facing up. See the user guide on the product CD for more
information.
● Envelopes: Load envelopes with the narrow, stamp side forward and the side to be
printed on facing up. See the user guide on the product CD for more information.
● Letterhead and preprinted forms: Load with the top forward and the side to be printed
on facing up. See the user guide for more information.
● Cards and custom-sized media: Load with the narrow side forward and the side to be
printed on facing up. See the user guide on the product CD for more information.
Media information for ADF originals
HP LaserJet 3015: you must use a carrier sheet to scan or copy small or delicate originals
(such as newsprint, business cards, and photos), or documents that have tears, perforations,
or punch holes.
HP LaserJet 3020 and 3030: you must use the flatbed to scan or copy small or delicate
originals (such as newsprint, business cards, and photos), or documents that have tears,
perforations, or punch holes. If you want to fax such items, first make a copy on the flatbed
and then fax the copy.
Perform the following actions to minimize the possibility of jams:
● Remove self-stick notes.
● Remove staples and paper clips.
● Straighten any curls, folds, or wrinkles in documents before putting them into the
document feeder tray.
ENWW Loading media 43
● Do not insert any document that contains glue, correction fluid, or wet ink.
● Do not insert gum-backed paper or labels.

Cleaning the print-cartridge area
You do not need to clean the print-cartridge area often. However, cleaning this area can
improve the quality of your printed sheets. During the printing process, paper, toner, and dust
particles can accumulate inside the product. Over time, this buildup can cause print-quality
problems, such as toner specks or smearing. To correct and prevent these types of problems,
you can clean the print-cartridge area and the media path.

Basic functions (all models)
This chapter presents a functional overview of the HP LaserJet 3015, 3020, and 3030 all-inone products. The following systems are discussed:
● printer functions and operation
– engine controller unit (ECU) system/power system
– laser/scanner system
– image-formation system
– paper-feed system (printer) and document-feed system (document scanner)
● formatter functions
● scanner and ADF functions and operation
● fax functions and operation (HP LaserJet 3015 and 3030 only)
The full product consists of the following components:
● the scanner and ADF
● the HP LaserJet 3015 uses a fixed contact image scanner (CIS)
● the HP LaserJet 3020 and 3030 use a flatbed charged-coupled device (CCD)
● the printer
● the formatter
● the line interface unit (LIU) (HP LaserJet 3015 and 3030 only)
Each of these systems brings its own characteristic functionality to the product: scanning,
printing, and telecommunications (HP LaserJet 3015 and 3030 only), respectively. These
systems interact to provide copying and faxing capability (only the HP LaserJet 3015 and 3030
have faxing capability).
● The scanner and printer work together to make copies.
● The scanner and LIU work together to send faxes (HP LaserJet 3015 and 3030 only).
● The LIU and printer work together to receive faxes (HP LaserJet 3015 and 3030 only).
The ECU controls the operation sequences of the printer. The formatter controls the operation
sequences of the LIU (HP LaserJet 3015 and 3030 only) and document scanner.

HP LaserJet 3015, 3020, and 3030 printer (product base) timing diagram
74 Chapter 4 Operational overview ENWW
Formatter system
The formatter coordinates the major systems. It is responsible for the following tasks or
actions:
● formatting and controlling copies
● receiving and processing print data from the printer interface
● monitoring the control panel and relaying printer-status information
● developing and coordinating data placement and timing with the print engine
● communicating with the host computer through the bidirectional interface
● communicating fax data to and from the LIU (HP LaserJet 3015 and 3030 only)
The formatter receives print data from the bidirectional enhanced capabilities port (ECP) mode
interface or universal serial bus (USB) interface and converts it into a dot image. The ECU
synchronizes the image-formation system with the paper-feed system and signals the
formatter to send the print-image data. The formatter sends the print-image data (dots) in the
form of a video signal, and the printing process begins.
Central processing unit
The formatter incorporates an embedded Coldfire V4 processor operating at 133 MHz.
Line interface unit (HP LaserJet 3015 and 3030 only)
The line interface unit (LIU) provides the required safety isolation, signal coupling, and
impedance matching between the telephone line and the modem chipset that is located on the
formatter.
Standard boot process
When the product is unplugged or the power is off, the firmware code is stored on the
formatter in two blocks. The first block of code is an executable boot block (about 64 K of
code). The second block of code is a compressed version of the product control code.
When the product is turned on, the boot block decompresses the product control code and
stores it in RAM. Then the product performs a full startup with the control code running from
RAM.
Product startup messages
The LED display contains different messages depending upon the progress of the boot
process:

RAM
The product contains two types of random-access memory (RAM):
● One bank of nonvolatile RAM (NVRAM) stores parameters.
● Dynamic random access memory (DRAM) provides temporary storage of the product
program code along with copy, scan, and print data.
Parallel interface or universal serial bus (USB) interface
The formatter receives incoming data through its bidirectional ECP or USB interface. These
interfaces provide high-speed, two-way communication between the product and the host,
allowing you to change product settings and monitor product status from the host computer.
Control panel
The control panel consists of the following features:
● groups of buttons to control fax, copy, scan, and configuration functionality (only the HP
LaserJet 3015 and 3030 have fax capability)
● a 2-by-16 LCD display that shows status, menus, and messages
● front-panel status lights
● the HP LaserJet 3015 and 3030 have three LED status lights
● the HP LaserJet 3020 has two LED status lights
EconoMode
When you select EconoMode (draft) in the printer driver, the product uses less toner, which
extends the life of the print cartridge.
76 Chapter 4 Operational overview ENWW
Note
When using EconoMode image quality (both clarity and contrast) will be considerably
decreased because less toner is applied to the page.
MEt
HP Memory Enhancement technology (MEt) effectively doubles the standard memory through
a variety of font- and data-compression methods.
Enhanced I/O
The enhanced I/O (EIO) feature allows product memory to be used for storing data received
from the host computer. When EIO is enabled, you can send more data to the product in
shorter amounts of time, so that you can return to the software program more quickly. The EIO
feature has the following options:
● Auto —the product uses EIO memory allocation to increase the speed of data transfer
from the host computer to the product, if necessary. The default setting is Auto.
● Off —the minimum amount of product memory is used to store data that is sent from the
host computer.
● Page Protect—the formatter creates the entire page image in page-buffer memory before
physically moving the media through the printer. This process ensures that the entire page
will be printed.
Page complexity (ruling lines, complex graphics, or dense text) can exceed the printer’s ability
to create the page image fast enough to keep pace with the image-formation process. If Page
Protect is disabled and a page is too complex, the page might print in sections (for example,
the top half on one page and the bottom half on the next page). Some print-data loss is likely
in these instances, and an error message will appear on the control-panel display.
PJL overview
Printer job language (PJL) is an integral part of configuration, in addition to the standard
printer command language (PCL). With standard ECP cabling, the product can use PJL to
perform the following functions:
● Two-way communication with the host computer through a bidirectional parallel
connection. The product can communicate information to the host (such as the controlpanel status).
● Isolation of print environment settings from one print job to the next. For example, if a
print job is sent to the product in landscape mode, the subsequent print jobs print in
landscape only if they are formatted for landscape printing.

Engine control system (engine control unit and power-supply assembly)
The engine control system coordinates all print engine activities. The engine control system
includes both the engine control unit (ECU) printed circuit assembly (PCA) and the powersupply assembly PCA.
78 Chapter 4 Operational overview ENWW
Note
In other HP LaserJet products, the ECU and power functions are combined onto one PCA
known as the controller PCA or the DC controller PCA. In the HP LaserJet 3015, 3020, and
3030, the control functions are primarily relegated to the ECU PCA and the power functions to
the power-supply assembly PCA.
The ECU controls the following systems and functions:
● Printer engine control
● paper-motion monitoring and control (printing)
● motor
● Printer laser/scanner unit
The power-supply assembly provides the following functions to the power system:
● ac power distribution
● dc power distribution
● overcurrent/overvoltage protection
● high-voltage power distribution

Power system on the power-supply assembly
The ac, dc, and high-voltage power supply circuits are all provided by the power-supply
assembly.
Ac power distribution
The ac power circuitry supplies ac voltage whenever the power cord is connected to the ac
power source and the power switch is on. The ac voltage is distributed to the dc power supply
circuitry and to the ac driver circuitry, which controls ac voltage to the fuser assembly heating
element.
Dc power distribution
The dc power distribution circuitry, located on the engine power assembly, distributes +3.3
Vdc, +5 Vdc, and +24 Vdc as follows:

Overcurrent/overvoltage
There are two overvoltage devices in this product:
● Fuse F101 provides overcurrent protection for the fusing system circuitry.
● Fuse F102 (110 V products only) provides overcurrent protection to the printer dc power
supply circuitry.
You can check or replace the fuses by removing the left cover.
Note
If either of these fuses fail, replace the engine power supply. See Power supply.
High-voltage power distribution
The high-voltage power supply applies an overlap of dc and ac voltage to the primary charging
roller and to the developing roller. This circuit also applies a positive or negative dc voltage to
the transfer roller according to the instructions from the engine control unit.
