98/Me/2000/XP, iMac and Power Macintosh)
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 95/98/Me, Windows
®
NT, Windows® 2000/XP, UNIX, Novell, Apple Macintosh, LAN server
®
and OS/2 Warp server computer simultaneously can access this printer. For further information, see the Network User’s Guide supplied with the printer.

CHAPTER 1 GENERAL
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. PRINTING METHODS

The printer provides two types of printing method; printing from the paper tray and printing 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
2-14
Page 46
HL-5030/5040/5050/5070N SERVICE MANUAL
(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

Page 47
CHAPTER 2 INSTALLATION AND BASIC OPERATION
(3) Pull out the MP tray support flap.
(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 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

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.

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 printing, close the back output tray to reset the two blue tabs back to their original position.
Fig.2-32

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

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.

Page 64

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.

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;
Paper path
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.

HL-5030/5040/5050/5070N SERVICE MANUAL
First feed pinch roller
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.

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 Drum Unit

2.4.1 Photosensitive drum
Generates the latent electrostatic image and develops the image on the drum surface.
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.

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.

CHAPTER 4 DISASSEMBLY AND RE-ASSEMBLY

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 M3: 0.7N y m M4: 0.8N y m
TAPTITE, CUP S M3: 0.8N y m
SCREW M3: 0.7N y m M4: 0.8N y m
(7) When connecting or disconnecting cable connectors, hold the connector body, not the
cables. If the connector has a lock, release the connector lock first to release it.
(8) After a repair, check not only the repaired portion but also all connectors. Also check
that other related portions are functioning properly before operational checks.
