REGULATION

LASER SAFETY (100 - 120V MODEL ONLY)

This printer is certified as a Class 1 laser product under the U.S. 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 protective housings
and external covers, the laser beam cannot escape from the machine during any phase of
user operation.

FDA REGULATIONS (100 - 120V MODEL ONLY)

U.S. 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.

IEC 60825 (220-240V MODEL ONLY)

This printer is a Class 1 laser product as defined in IEC 60825 specifications. The label
shown below is attached in countries where it is required.

This printer has a laser diode which emits invisible laser radiation in the Laser Unit. The
Laser Unit should not be opened without disconnecting the two connectors connected with
the AC power supply and laser unit. Since the variable resistor in the laser unit is adjusted
in accordance with the standards, never touch it.

Caution

Use of controls, adjustments or performance of procedures other than those specified in
this manual may result in hazardous radiation exposure.

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.

Enhanced Printing Performance and User-Friendly Operation for Windows

The dedicated printer driver for Microsoft
Windows



2000/XP Home Edition/XP Professional/XP Professional x64 Edition are available



Windows 95/98/Me, Windows NT 4.0 and

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. The animated
dialog box appears on your computer screen to show the current printing process when
printing. 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 pages
1200 dpi graphic and text data, including large fonts, with the standard printer memory.

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 CD­ROM supplied with the printer.

Popular Printer Emulation Support

These printers support the following printer emulation modes.
BR-Script 3, HP LaserJet (PCL6), Epson FX-850 and IBM Proprinter XL.

Environment-Friendly

<Economy Printing Mode (Toner Save 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 8.5W 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 3,500 (Standard cartridge) pages or 7,000 (High yield cartridge)
at 5% coverage for A4 paper for the standard cartridge, which is both cost effective and
ecologically friendly.

Bar Code Print

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-5250DN/5270DN/5280DW)

The Brother printer has built in multi protocol network capability as standard. This allows
multiple host computers to share the printer on a 10/100Mb wired Ethernet or IEEE

802.11b/802.11g wireless 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 tray to avoid any
paper jams or misfeeds.
