REGULATION
LASER SAFETY (110 - 120V MODEL ONLY)
This printer is certified as a Class I laser product under the US Department of Health and
Human Services (DHHS) Radiation Performance Standard according to the Radiation
Control for Health and Safety Act of 1968. This means that the printer does not produce
hazardous laser radiation.
Since radiation emitted inside the printer is completely confined within the protective
housing and external covers. the laser beam cannot escape form the machine during any
phase of user operation.
FDA REGULATIONS (110 - 120V MODEL ONLY)
The US Food and Drug Administration (FDA) has implemented regulations for laser
products manufactured on and after August 2, 1976. Compliance is mandatory for
products marketed in the United States. One of the following labels on the back of the
printer indicates compliance with the FDA regulations and must be attached to laser
products marketed in the United States.

SAFETY INFORMATION
CAUTION FOR LASER PRODUCT (WARNHINWEIS FUR LASER DRUCKER)
CAUTION: When the machine during servicing is operated with the cover open, the
regulations of VBG 93 and the performance instructions for VBG 93 are
valid.
CAUTION: In case of any trouble with the laser unit, replace the laser unit itself. To
prevent direct exposure to the laser beam, do not try to open the enclosure
of the laser unit.
ACHTUNG: Im Falle von Störungen der Lasereinheit muß diese ersetzt werden. Das
Gehäuse der Lasereinheit darf nicht geöffnet werden, da sonst
Laserstrahlen austreten können.
<Location of the laser beam window>
ADDITIONAL INFORMATION
When servicing the optical system of the printer, be careful not to place a screwdriver or
other reflective object in the path of the laser beam. Be sure to take off any personal
accessories such as watches and rings before working on the printer. A reflected beam,
though invisible, can permanently damage the eyes.
Since the beam is invisible, the following caution label is attached on the laser unit.

CHAPTER 1 GENERAL
1. FEATURES
This printer has the following features;
High Resolution and Fast Print Speed
True 600 x 600 dots/ true 300 x 300 dots per inch (dpi) and HQ1200 for graphics with
microfine toner and up to 17 (HL-5130)/ 20 (HL-5140/5150D/5170DN) pages per minute
(ppm) print speed for A4 and 18 (HL-5130)/ 21 (HL-5140/5150D/5170DN) pages per minute
(ppm) print speed for Letter- size paper.
Versatile Paper Handling
The printer loads paper automatically from the paper tray. The paper tray can hold A4, letter,
B5 (ISO), A5, B6 (ISO), A6, Executive and Legal size of paper. The manual feed tray (HL-
5130/5140) allows manual paper loading sheet by sheet so you can use a variety of types and
sizes of paper. The multi-purpose tray (HL-5150D/5170DN) also allows you to use a variety
of types and sizes of paper.
Front Operation
Basic operation of the printer can be controlled from the control panel.
Enhanced Printing Performance and User-Friendly Operation for Windows
The dedicated printer driver for MicrosoftWindows95/98/Me, WindowsNT 4.0 and
Windows2000/XP are available on the CD-ROM supplied with your printer. You can easily
install them into your Windowssystem using our installer program. The driver supports our
unique compression mode to enhance printing speed in Windowsapplications and allows
you to choose various printer settings including toner save mode, custom paper size, sleep
mode, gray scale adjustment, resolution, water mark and many layout functions. You can
easily setup these print options through the Printer Setup Menu.
Printer Status Monitor with Bi-directional Parallel Interface
The printer driver can monitor the status of your printer using bi-directional parallel
communications. IEEE-1284 bi-directional parallel printer cable is recommended.
The printer status monitor program can show the current status of your printer. When printing,
the animated dialog box appears on your computer screen to show the current printing
process. If an error occurs, a dialog box will appear to let you know what to correct. If you
have turned on the interactive Help (Windows only) you can get visual guidance on your PC
screen on the actions in the event of certain printer errors. The default setting is OFF.
Quick Print Setup
The Quick Print Setup is a convenient utility to allow you to make changes to frequently used
driver settings easily without having to open the printer properties selection box every time. It
is launched automatically when this printer driver is selected. You can change the settings by
clicking on the icon with the right mouse button. The default setting is OFF.
Enhanced Memory Management
The printer provides its own data compression technology in its printer hardware and the
supplied printer driver software, which can automatically compress graphic data and font data
efficiently into the printer’s memory. You can avoid memory errors and print most full page
600 dpi graphic and text data, including large fonts, with the standard printer memory.

USB Interface (for Windows98/Me/2000/XP, iMac and Power Macintosh)
The printer can be connected using the Universal Serial Bus (USB) interface to a PC or Mac
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-5140/5150D/5170DN 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-5140: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-5150D/5170DN printers. The printers also support
auto-emulation 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-5130/5140/5150D), 6W(HL-
5170DN) 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 6,700 (High-yield toner cartridge)/ 3,500 (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-5140/5150D/5170DN 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-5170DN only)
The Brother printer has built in multi protocol network capability as standard. This allows
multiple host computers to share the printer on a 10/100Mbps 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
