which has a USB interface. Drivers that allow you to use the USB port are provided on the
CD-ROM supplied with the printer.

Popular Printer Emulation Support (HL-5040/5050/5070N only)

These printers support the following printer emulation modes;
HP LaserJet (PCL6), PostScript Level 3 language emulation (Brother BR-Script Level 3),
Epson FX-850 and IBM Proprinter XL.
HL-5040:only HP LaserJet (PCL6)
When you use DOS application software or Windows version 3.0 or earlier, you can use any
of these emulations to operate the HL-5050/5070N printers. The printers also support auto­emulation switching between HP, Brother BR-Script 3 and Epson or HP, BR-Script 3 and IBM.
If you want to set the printer emulation, you can do it using the Remote Printer Console
Program.

High Resolution Control

High Resolution Control (HRC) technology provides clear and crisp printouts. Use this
function to get smooth text print quality. (300 dpi, 600dpi only)

Environment-Friendly

<Economy Printing Mode>
This feature will cut your printing cost by saving toner. It is useful for obtaining draft copies for
proof-reading. You can select the toner saving economy mode through the Windows



printer

driver supplied with your printer.

<Sleep Mode (Power Save Mode)>
Sleep mode automatically reduces power consumption when the printer is not in use for a
certain period of time. The printer consumes less than 5W(HL-5030/5040/5050), 6W(HL­5070N) when in sleep mode.

<Low Running Cost>
Since the toner cartridge is separate from the drum unit, you need to replace only the toner

cartridge after printing around 6,500 (High-yield toner cartridge)/ 3,300 (Standard toner
cartridge) pages at 5% coverage for A4 paper for the standard cartridge, which is both cost
effective and ecologically friendly.

Bar Code Print (HL-5040/5050/5070N only)

The printer can print the following 11 types of bar codes;

• Code 39 • US-PostNet • EAN-8

• Code 128 • ISBN • EAN-13

• Interleaved 2 of 5 • UPC-A • EAN-128

• Codabar • UPC-E

Network Feature (for HL-5070N only)

The Brother printer has built in multi protocol network capability as standard. This allows
multiple host computers to share the printer on a 10/100Mbit Ethernet network. Any users can
print their jobs as if the printer was directly connected to their computer. Users on Windows

®

CAUTION:

When you are choosing print media, be sure to follow the information given below to prevent
any paper jams, print quality problems or printer damage;

• It is recommended to use long-grained paper for the best print quality. If short-grained
paper is being used, it might be the cause of paper jams.

• Use neutral paper. Do not use acid paper to avoid any damage to the drum unit.

• Avoid using coated paper such as vinyl coated paper.

• Avoid using preprinted or highly textured paper.

• It is recommended to use labels or transparencies which are designed for use in laser

printers.

• Avoid feeding labels with the carrier sheet exposed, or the printer will be damaged.

• Before loading paper with holes such as organizer sheets, be sure to fan the stack well.

• Do not use organizer sheets that are stuck together. The glue that is used might caused

damaged to the printer.

• When printing on the back of pre-printed paper, if the paper is curled, be sure to straighten
the paper as much as possible.

• Different types of paper should not be loaded at the same time in the paper cassette to
avoid any paper jams or misfeeds.

4 ppm *

*The print speed may vary according to conditions, such as paper size and paper tray.

NOTE:

• When a smaller size paper than A4 or Letter is printed, the temperature on both edges of
the fixing unit is much higher than the temperature on the center of the unit where the
paper is fed depending on the setting or model. Therefore, the print speed is slowed in
order to decrease the temperature on the edges after the specified time, it is maximum
print speed when you first start printing.

• Max. speed is 16/17 ppm or more. It varies depending on the paper size.

from the multi-purpose tray.

4.1 Printing from the Paper Tray

You can load plain paper, recycled paper or transparencies into the paper tray. If paper is
loaded into the paper tray, the printer automatically feeds paper sheet by sheet and ejects the
printed page into the output tray.

For the details on cassette loading, refer to subsection 3.1.2 ‘Load paper into the paper tray’ in

this chapter and subsection 3.5 ‘Paper’ in CHAPTER 1.

4.2 Printing from manual feed tray (HL-5030/5040 only)

(1) Select the Paper Size, Media Type and paper Source etc. in the printer driver.
(2) Send the print data to the printer.

NOTE: A NO PAPER message is shown in the Status Monitor and indicated by the control
panel LEDs until you put a sheet of paper in the manual feed tray,

Fig.2-12

(3) Open the manual feed tray. Slide the paper guides to fit the paper size.

Fig.2-13

HL-5030/5040/5050/5070N SERVICE MANUAL

2-15

(4) Using both hands to put paper in the manual feed tray until the front edge of the paper

touches the paper feed roller. Hold the paper in this position until the printer automatically
feeds the paper in for a short distance, and then let go of the printer.

Fig.2-14

NOTE: Make sure the paper is neatly stacked and in the proper position on the manual feed

tray. If it is not, the paper may not be fed correctly, resulting in a skewed printout or a
paper jam.

Do not put more than one piece of paper in the manual feed tray at any one time, or it

may cause a jam.

If you put any Media (paper, transparency and so on) in the manual feed tray before

the printer is in the READY state, the media may be ejected without being printed on.

(5) After the printed page comes out of the printer, put in the next sheet of paper as in Step 4

above. Repeat for each page that you want to print.

4.3 Printing from Multi-purpose Tray (MP Tray) : HL-5050/5070N only

You can feed bond paper, thick paper, labels, envelopes or cards as well as plain paper,
recycled paper or transparencies into the multi-purpose tray. (For details on feedable paper,
see subsection 3.5 ‘Paper’ in CHAPTER 1.)

NOTE:

• For correct printing, the same paper size must be selected from within the software

application as the paper in the tray.

When using the multi-purpose tray, follow the steps below;

(1) Select the Paper Size, Media Type and paper Source etc. in the printer driver.

(2) Open the MP tray and lower it gently.

Fig. 2-15

CHAPTER 2 INSTALLATION AND BASIC OPERATION

(3) Pull out the MP tray support flap.

Fig. 2-16

(4) When loading paper in the MP tray, make sure it touches the back of the tray and remains

under the maximum paper height guides on both sides of the tray.

NOTE:
Note the following when placing paper on the multi-purpose tray:

• If the paper to be printed on weighs more than 105 g/m

2

(28 lbs), use the face up output

tray.

• Insert the leading edge of the paper first and push it gently into the tray.

• If pre-printed paper is used in the multi-purpose tray, the paper should be inserted top

edge first with the printed side face up.

• Make sure that the paper is straight and in the proper position on the MP tray. If it is not,
the paper may not be fed properly, resulting in a skewed printout or a paper jam.

(5) While pressing the paper-guide release lever, slide the paper guide to fit the paper

size.

NOTE:
*The side to be printed on must be face up.
*During printing, the inside tray rises to feed paper into the printer.

(6) Send the print data to the printer.

4.4 Printing on envelopes

Use of any of the envelopes listed below may cause damage to the printer. Such damage is
not covered under any warranty or service agreement.

• Envelopes that are damaged, curled, wrinkled, or irregularly shaped

• Envelopes that are extremely shiny or highly textured

• Envelopes with clasps, snaps or tie strings

• Envelopes with self-adhesive closures

• Envelopes of baggy construction

• Envelopes that are not sharply creased

• Embossed envelopes

• Envelopes that were previously printed by a laser printer

• Envelopes that are pre-printed on the inside

• Envelopes that cannot be arranged uniformly when placed in a pile

• Envelopes constructed with paper that exceeds the paper weight specifications for the

printer.

• Poorly manufactured envelopes with edges that are not straight or consistently square.

• Envelopes with transparent windows, holes, cutouts or perforations.

NOTE:

• Before printing envelopes, fan the stack well to avoid paper jams and misfeeds.

• Do not load different types of paper at the same time in the paper tray because it may

cause paper jams or misfeeds.

• Do not print envelopes using manual duplex printing.

• For proper printing, you must choose the same paper size from your software application

as the paper in the tray.

• Most envelopes will be suitable for your printer. However, some envelopes will have feed
and print-quality problems because of the way they have been made. A suitable
envelope should have edges with straight, well-creased folds and the leading edge
should not be thicker than two pieces of paper. The envelope should lie flat and not be of
baggy or flimsy construction. You should buy quality envelopes from a supplier who
understands that you will be using the envelopes in a laser printer. Before you print a lot
of envelopes, test one to make sure that the print results are what you want.

• Brother will not recommend a particular envelope because envelope manufacturers may
change the envelope specifications. You are responsible for the quality and performance
of envelopes you use.

Printing on envelopes from the manual feed tray (For HL-5030 and HL-5040)

The printer has a straight paper path from the manual feed tray to the back of the printer. Use
this paper feed and output method when you want to print envelopes.

The printer automatically turns on the Manual Feed mode when you put paper in the manual
feed tray.

4.7 Guidelines for printing on both sides of the paper

• If the paper is thin, it may wrinkle.

• If paper is curled, straighten it and then put it back in the paper tray.

• You should use regular paper. Do not use bond paper.

• When you put paper in the paper tray, first empty the tray then put the printed page in it,

with the printed side face up. (Do not add the printed pages to the top of the stack of
unprinted paper.

• If the paper is not feeding properly, it may be curled. Remove the paper and straighten it.

NOTE: For Thicker paper that has curled once the first side has been printed on, and you

cannot feed the paper for the second time from manual feed tray or MP tray to allow the
other side of the paper to be printed on:

At the back of the printer, open the back output tray and push down the blue tabs at the
left and right hand sides (as shown in the figure below). When you have finished

4.8 Paper orientation for printing on both sides of the paper

The printer prints the second page first.
If you print 10 pages on 5 sheets of paper, it will print page 2 then page 1 on the first sheet of

paper.
It will print page 4 then page 3 on the second sheet of paper.
It will print page 6 then page 5 on the third sheet of paper, and so on.

When doing manual duplex printing, the paper must be put in the paper tray in the following
way:

*For the manual feed tray or the multi-purpose (MP) tray

Put the side to be printed on first, in face-up, with the leading edge (top) of the paper in first.
To print the second side, put the paper face down, with the leading edge (top) of the paper in

first.
If letterhead paper is used, this would be put in to the MP tray with the heading facedown,

and in first.
To print the second side, put the heading face up and in first.

*For the upper paper tray and the optional lower tray (tray 1 or tray 2)

Put the side to be printed on first, face down, with the leading edge (top) of the paper at the
front of the tray.

To print the second side, put the paper face up, with the leading edge (top) of the paper at
the front of the tray.
If letterhead paper is used, this would be put in to the paper tray with the heading face up,
and at the front of the tray.

To print the second page, put the heading face down and at the front of the tray.

5.5 Other Control Features

The printer has the following useful features;

5.5.1 Sleep mode

When the printer does not receive data for a certain period of time (timeout), it enters sleep
mode. The default timeout is 5 minutes and it is automatically adjusted to the most suitable
time-out setting depending on the frequency of your printer use (Intelligent Sleep Mode).

While the printer is in sleep mode, all the LEDs are off and it is as if it was turned off, but the
printer can still receive data from the computer. Receiving a print file or document
automatically wakes up the printer to start printing. Pressing the button also wakes up the
printer.

NOTE:

• When the printer goes into sleep mode, the fan will not stop until the printer engine has

cooled down. The fan running time varies depending on the sleep mode timeout because
the fan running conditions are defined as follows;

1) The fan runs for 10 minutes whenever printing finishes.

2) The fan runs while the printer is in ready status.

3) The fan runs for at least 5 minutes after the printer goes into sleep mode.

(EX: If the timeout is 5 minutes, the fan will be running for 5 minutes after the printer goes into

sleep mode.)

• Sleep mode allows the print engine to cool, so the temperature of the room and how long

the printer has been in sleep mode affects the warm-up time. This warm-up time can take
up to 25 seconds. The Ready LED blinks to indicate that the printer is warming up.

• You can change the timeout for the sleep mode with the supplied printer driver (all

models) . The time-out setting is in the range of 1 to 99 minutes. Refer to the Help section
in the printer driver for more information about the sleep mode setting.

CHAPTER 2 INSTALLATION AND BASIC OPERATION

2-36

6. NETWORK FUNCTIONS

6.1 LED functions

Fig. 2-48

No light:

If both of the two LEDs are off, then the print server is not connected to the network.

Link/Speed LED is orange: Fast Ethernet

Link/Speed LED is green: 10 Base T Ethernet

This Link/Speed LED will be orange if the print server is connected to a 100BaseTX Fast
Ethernet network.

This Link/Speed LED will be green if the print server is connected to a 10 Base T Ethernet.

Active LED is yellow:

The Active LED will blink if the print server is receiving or transmitting data.

6.2 Network Factory default setting (For HL-5070N)

If you wish to reset the print server back to its default settings (resetting all information such
as the password and IP address information), please follow these steps;

(1) Turn off the printer.

(2) Make sure that the front cover is closed and the power cord is plugged in.

(3) Hold down the Go button as you turn on the power switch. All the LEDs will light up. Keep

the Go button pressed down until all the LEDs except for Toner LED go off. When the
Drum, Paper and Status LEDs go off, release the Go button.

(4) Hold down the Go button and keep it pressed down until the yellow Status LED comes on.

When the Status LED comes on, release the Go button.

(5) When all the LEDs light up again, the printer will start warming up. The print server has

been reset to its default factory settings.

NOTE:
*If you wish to reset the printer and automatically disable the APIPA protocol, follow steps 1 to

4 above, however, hold down the Go button until the Status LED is green, not yellow.
*For more information on APIPA, see the Network User’s Guide or visit

7. PAPER CASSETTE INFORMATION (FOR EUROPE ONLY)

The paper cassette fitted to the printer is different from the service manual information for
printers shipped to Europe as follows:

(1) The paper cassette supplied with the HL-

5030/5040/5050/5070N printer does not
have a paper path.

(2) The paper cassette supplied with the LT-

5000 (optional Lower Tray Unit, for HL­5040/5050/5070N only) has a paper path
as shown on the right;

Fig. 2-49

(3) (For HL-5040/5050/5070 only)

When you install the LT-5000 unit to the printer, it is necessary to exchange the paper
cassette already equipped (standard cassette) with the LT-5000 unit, and install the
standard cassette to the lower tray.

Failure to do so will cause paper jams as the paper cannot be fed from the lower cassette
to the printer body because the paper path will be blocked.

(4) For paper cassettes supplied as spare parts, there is a paper path so that you can use it

as both an upper cassette and lower cassette.

DIAGRAM’ in this manual.

1.3.1 CPU

A Fujitsu 32bit RISC CPU, SPARClite is built in the ASIC. While the CPU is driven with a
clock frequency of 66.66 MHz in the user logic block, it itself runs at 133.33 MHz, which is
generated by multiplying the source clock by two.

2.2 Paper Transfer

2.2.1 Paper supply

The paper pick-up roller picks up one sheet of paper from the paper cassette every time it is
rotated and feeds it to the paper feed roller.

Fig. 3-32

The paper is gripped between the paper pick-up roller and the separation pad and separated
into individual sheets.

The pick-up roller is directly connected to the clutch mechanism, whose rotation is stopped by
the stopper arm. When the pick-up solenoid is activated, the clutch mechanism is engaged by
the solenoid action and the paper pick-up roller is driven. The paper drawn out of the tray by
the pick-up roller pushes against the regist front actuator and the paper top position/absence
of paper is detected by sensing the motion of the actuator.

2.2.2 Paper registration

After the paper top position is detected by the regist front actuator, the paper, separated into
individual sheets by the paper pick-up roller, is fed further for a specified time, and the paper
top position reaches the paper feed roller so that the paper skew is adjusted. Then, the
solenoid is turned off, the paper feed roller starts turning, and the paper is fed to the transfer
block in the drum unit.

Fig. 3-33

The regist rear actuator in the path from the feed roller to the transfer roller controls the first
print position on the paper.

2.2.3 Paper eject

After the printing image on the photosensitive drum is transferred onto the paper, the paper is
fed to the fixing unit to fix unfixed toner onto the paper.

Afterwards, the paper is ejected from the fixing unit by the first eject roller in the fixing unit.
The paper eject actuator detects whether the paper is ejected correctly or not.

After the paper exits from the first eject roller, the paper is turned by the rear cover and
ejected face down into the top output tray through the second eject roller. If the rear cover is
open, the paper is ejected face up straight to the printer rear (straight paper path).

2.4.2 Primary charger

Forms a uniform charge on the drum surface.

(1) Corona wire

Generates the ion charge on the drum.

(2) Grid

Spreads the ion charge evenly over the drum surface.

2.4.3 Transfer roller

Transfers the toner image to the paper from the drum surface.

2.4.4 Cleaner

Removes the paper dust or dirt on the surface of the photosensitive drum.

2.5 Toner Cartridge

Develops the electrostatic latent image on the photosensitive drum with toner and forms the
visible image.

2.6 Print Process

2.6.1 Charging

The drum is charged to approximately 870V by an ion charge which is generated by the
primary charger. The charge is generated by ionization of the corona wire, which has a DC
bias from the high-voltage power supply applied to it. The flow of the ion charge is controlled
by the grid to ensure it is distributed evenly on the drum surface. The aluminum drum sleeve
in the photosensitive drum is grounded.

The primary charge uses a corona wire, but since the drum is positively charged, only less
than 1/10 of the usual quantity of ozone is generated compared with the negatively charged
drum. The level of ozone expelled from the printer is therefore not harmful to the human body.
Applicable safety standards have been complied with.

2.6.3 Developing

Developing causes the toner to be attracted to the electrostatic image on the drum so as to
transform it into a visible image.

The developer consists of a non-magnetic toner. The development roller is made of
conductive rubber and the supply roller (which is also made of conductive sponge) rotate
against each other. The toner is charged and carried from the supply roller to the
development roller. The toner adheres to the development roller and is conveyed to the
photosensitive drum at an even thickness controlled by the blade. The toner is nipped
between the development roller and the drum and developed onto the latent image on the
drum. The electrostatic field between the drum and the development roller, which is DC­biased from the high-voltage power supply, creates the electrostatic potential to attract toner
particles from the development roller to the latent image area on the drum surface.

Fig. 3-43

2.6.4 Transfer

(1) Transfer process

After the drum has been charged and exposed, and has received a developed image, the
toner formed is transferred onto the paper by applying a negative charge to the back of
the paper. The negative charge applied to the paper causes the positively charged toner
to leave the drum, and adhere to the paper. As a result, the image is visible on the
paper.

(2) Cleaning process of transfer roller

If the toner is not transferred onto the paper perfectly it is possible that there may be
residual toner on the drum which will adhere to the transfer roller. The transfer voltage
changes to a positive voltage during non-printing rotation of the drum. Therefore the
transfer roller is cleaned by returning the positively charged toner adhering to the transfer
roller onto the photo-conductive drum.

The image transferred to the paper by static electricity is fixed by heat and pressure when
passing through the heat roller and the pressure roller in the fixing unit. The thermistor keeps
the surface temperature of the heat roller constant by detecting the surface temperature of the
heat roller and turning on or off the halogen heater lamp.

1. SAFETY PRECAUTIONS

To avoid creating secondary problems by mishandling, follow the warnings and precautions below

during maintenance work.

WARNING

(1) Always turn off the power switch and unplug the power cord from the power outlet

before accessing any parts inside the printer.

(2) Some parts inside the printer are extremely hot immediately after the printer is

used. When opening the front cover or rear cover to access any parts inside the
printer, never touch the red colored parts shown in the following figures.

!

CAUTION:

(1) Be careful not to lose screws, washers, or other parts removed.

(2) Be sure to apply grease to the gears and applicable positions specified in this chapter.

(3) When using soldering irons or other heat-generating tools, take care not to accidentally

damage parts such as wires, PCBs and covers.

(4) Before handling any PCBs, touch a metal portion of the equipment to discharge any static

electricity charge on your body, or the electronic parts or components may be damaged.

(5) When transporting PCBs, be sure to wrap them in the correct protective packaging.

(6) Be sure to replace self-tapping screws correctly, if removed. Unless otherwise specified,

tighten screws to the following torque values.

TAPTITE, BIND or CUP B
