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, iMac and Power Macintosh G3 using USB with HL1240/1250/1270N only)
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.
Remote Printer Console Program for DOS (for HL-1240/1250/1270N only)
The utility program, Remote Printer Console (RPC), is available on the CD-ROM supplied with
your printer. When you operate your computer in a DOS (Disk Operating System)
environment, this program allows you to easily change the default settings of the printer such
as fonts, page setup and emulations.
This program also provides a status monitor program, which is a Terminate-and-Stay Resident
(TSR) program. It can monitor the printer status while running in the background and report
the current status or errors on your computer screen.
Popular Printer Emulation Support (for HL-1240/1250/1270N only)
These printers support the following printer emulation modes;
The HL-1240 supports HP LaserJet IIP.
The HL-1250 supports HP LaserJet 6P (PCL6), Epson FX-850 and IBM Proprinter XL.
The HL-1270N supports HP LaserJet 6P (PCL6), PostScript Level 2 language emulation
(Brother BR-Script Level 2), Epson FX-850 and IBM Proprinter XL.
When you use DOS application software or Windows version 3.0 or earlier, you can use any
of these emulations to operate the HL-1250/1270N printers. The printers also support autoemulation switching between HP, Brother BR-Script 2 and Epson or HP, BR-Script 2 and IBM.
If you want to set the printer emulation, you can do it using the Remote Printer Console
Program.
High Resolution Control & Advanced Photoscale Technology (for HL-1250/1270N only)
High Resolution Control (HRC) technology provides clear and crisp printouts. Use this function
to get smooth text print quality.
Advanced Photoscale Technology (APT) enables the printer to print graphics in 256
grayscales, producing nearly photographic quality. Use this function when you want to print
photographic images.
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 from two economy modes, 25% toner saving and 50% toner
saving, 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-1030/1240), 6W (HL-1250) or
12W (HL-1270N) 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 around 3,000 pages for the standard cartridge and around 6,000 pages for the
optional high-capacity cartridge, which is both cost both effective and ecologically friendly.

CHAPTER 2 INSTALLATION AND BASIC OPERATION
5.5
Control Panel Button Operations
The control panel button is used for the following purposes depending on the situation.
5.6
Operation
Description
Cancel printing
If the button is pressed during printing, the printer immediately stops
printing and ejects the paper.
Wake-up
If the printer is in sleep mode, pressing the button wakes it up into the
ready status. It will take up to 45 seconds for the printer to go into the
ready status.
Form feed
If the Data LED is on, press the button. The printer prints any data
remaining in the printer memory.
Error recovery
If an error occurs, the printer will recover from some errors automatically.
If the error does not clear automatically, press the button to clear the error
and continue printer operation.
Reprint function
You can reprint a print job without sending it from the computer again.
When you press the button with the Data LED off, the printer reprints the
last job you printed if the whole job can be kept in printer memory. If the
print job is too large or there is insufficient memory, the last page only will
be reprinted.
Other Control Features
The printer has the following useful features;
5.6.1
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 45 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)
or Remote Printer Console program. The time-out setting is in the range of 1 to 15 minutes.
Refer to the Help section in the printer driver or RPC program for more information about
the sleep mode setting.

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.
Pinch roller

Separation pad
Pressure plate
Fig. 3-29
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 front registration sensor lever and the paper top
position/absence of paper is detected by sensing the motion of the lever.
2.2.2
Paper registration
After the paper top position is detected by the front registration sensor, 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.

CHAPTER 3 THEORY OF OPERATION
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
eject sensor lever 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).

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.
2.6.2

After the drum is positively charged, it is exposed to the light emitted from the laser unit.

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 DC-biased 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.

CHAPTER 3 THEORY OF OPERATION
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.
2.6.5
Fixing stage
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.

TROUBLESHOOTING
INTRODUCTION
Initial Check
(1) Operating environment
Check if :
• The source voltage stays within ±10% from the rated voltage shown on the rating plate.
• The printer is installed on a solid, level surface.
• The room temperature is maintained between 10°C and 32.5°C. The relative humidity is
maintained between 20% and 80%.
• The printer is not located in a dusty place.
• The printer is not exposed to ammonia fumes or other harmful gases.
• The printer is not located in a hot or humid area (such as near water or a humidifier).
• The printer is not exposed to direct sunlight.
• The room is well-ventilated.
• The printer is not placed where the ventilation hole of the printer is blocked.
(2) Print paper
Check if :
• A recommended type of print paper is being used. [If the paper is too thick or too thin,
or tends to curl, paper jams or paper feed problems may occur, or printed images may
be blurred.]
• The print paper is damped. [If so, use fresh paper, and check whether the print quality
improves or not.]
• The print paper is short-grained paper or acid paper. [If so, print quality problems may
occur.]
For further information on paper, refer to subsection 3.5 ‘Paper’ in CHAPTER 1.
(3) Consumable parts
Check if :
• The Toner LED is not lit on the printer control panel when a toner cartridge is installed in
the printer. [If the LED is lit, replace the cartridge with a new one.]
For further information on consumable parts, refer to Section 1 ‘Consumable Parts’ in
CHAPTER 5.
(4) Others
Condensation:
When the printer is moved from a cold room into a warm room in cold weather,
condensation may occur inside the printer, causing various problems as listed below:
• Condensation on the optical surfaces such as the scanning mirror, lenses, the reflection
mirror and the protection glass may cause the print image to be light.
• If the photosensitive drum is cold, the electrical resistance of the photosensitive layer is
increased, making it impossible to obtain the correct contrast when printing.
6-1
CHAPTER 6 TROUBLESHOOTING
• Condensation on the corona unit may cause corona charge leakage.
• Condensation on the hopper plate and separation pad may cause paper feed troubles.
If condensation has occurred, print several pages or leave the printer for 2 hours to allow it to
reach room temperature.
If the drum unit is unpacked soon after it is moved from a cold room to a warm room,
condensation may occur inside the unit, which may cause incorrect images. Instruct the user
to allow the unit to come to room temperature before unpacking it. This will take one or two
hours.
1.2
Warnings for Maintenance Work
To avoid creating secondary problems by mishandling, follow the warnings below during
maintenance work.
WARNING
(1) Always turn off the power switch and unplug the power cord from the power outlet

NETWORK PROBLEM (FOR HL-1270N ONLY)
If the error related to network occurs, refer to the following sections;
9.1
Installation Problem
If you cannot print over the network, check the following:
(1) Make sure that the printer is powered on, is on-line and ready to print.
Verify that the printer and the configuration are good by printing the Network Configuration
page. (To print the Configuration page press the Network Test button for less than 5
seconds.) If the test fails, check:
a) If the Alarm LED on the printer front panel is ON or blinking and all of the LEDs on the
back panel - near the UTP (Ethernet) connector - are OFF, or the Orange (F) LED is
blinking, then the network firmware settings may be corrupted.
b) In this event, try to restore the factory default settings of the print server by pressing
the Network Test button on the back panel of the printer for more than 5 seconds.
Once you have done that, turn the printer power off and then on again, and try to print
out the Network Configuration page.
(2) If the Configuration page is printed but you cannot print documents, try the following
NOTE:
If none of the following steps are successful, there is almost certainly a hardware or
network problem!
a) If you are using TCP/IP:
Try pinging the print server from the host operating system prompt with the command
ping ipaddress, where ipaddress is the print server IP address (note that in some
instances it can take up to two minutes for the print server to load its IP address (after
setting the IP address). If a successful response is received, then proceed to the
UNIX, TCP/IP Windows NT/LAN Server, Windows98/95 Peer to Peer (LPR), Internet
Printing or Web Browser troubleshooting section. Otherwise, proceed to step (3), and
then go to subsection 9.3 ‘TCP/IP Troubleshooting’.
b) If you are using Novell system:
Verify that the print server can be seen on the network. To do this, login as the
SUPERVISOR (not as someone with supervisor privileges) or ADMIN (for Netware 4
or later servers), go into PCONSOLE, select PRINT SERVER INFORMATION, and
select the name of the print server (make sure that you have entered the print server
name). If you can see Print Server Status and Control in the menu, then the
Brother print server is visible to the network, proceed to subsection 9.10 ‘Novell
NetWare Troubleshooting’. Otherwise, go to step (3).
c) If you are running AppleTalk for Macintosh:
Make sure that you can see the print server name under the LaserWriter 8 icon in the
Chooser. If it is visible, then the connection is good, so proceed to subsection 9.11
‘AppleTalk Troubleshooting’. Otherwise, go to step (3).
6-45
CHAPTER 6 TROUBLESHOOTING
(3) If you cannot make any of the connections in step (2), check the following:
a) Make sure the printer is turned on and on-line.
b) Verify that the cabling and network connection are good. If possible, try the print
server on a different connection on the network. Also, print out a Configuration page to
see if you can see any Network Statistics information.
c) Check to see if there is any LED activity.
The print server has three LEDs. These can be used to diagnose problems.
•
L- LED (green): Link activity
This LED is on if there is a valid connection to the network (either
10BaseT or 100BaseTX). It is off if no network is detected.
•
F-LED (orange): Fast Ethernet
This LED will be on if the print server is connected to a 100BaseTX Fast
Ethernet network. It is off if the print server is connected to a 10BaseT
network.
•
A-LED (green): Transmission Activity
This LED will blink synchronized to the transmission or receive status.
(4) If you are using a repeater or hub, make sure that SQE (heartbeat) is turned off at the hub.
Also, if you have a hub or multi-port repeater, verify that the hub or repeater port is good
by trying the print server on a different port.
(5) If you have a bridge or router located between the print server and host computer, make
sure that the device is set up to allow the print server to send and receive data from the
host. For example, a bridge can be set up to only allow certain types of Ethernet
addresses to pass through (a process known as filtering); therefore, such a bridge must
be configured to allow Brother print server addresses. Likewise, a router can be set up to
pass only certain protocols, so be sure that the desired protocol can be passed through to
the print server.
(6) If the job exits the queue but does not print, make sure that you are not trying to print a
text job to a PostScript printer. If you have a printer that is capable of automatic language
switching, make sure that the printer is not forced into PostScript mode.
9.2
Intermittent Problem
If the print server and printer start up OK, but you intermittently have problems printing, check
the following:
(1) If you can print small jobs but large graphics jobs are distorted or incomplete, make sure
that you have adequate memory in your printer and the latest printer driver installed on
your computer. The latest Brother printer drivers can be downloaded from
www.brother.com.
(2) Check the individual protocol troubleshooting sections in this chapter for additional causes
of intermittent printer problems.
6-46
CHAPTER 6 TROUBLESHOOTING
9.3
TCP/IP Troubleshooting
If you are using TCP/IP and cannot print to the print server and you have checked the
hardware and network as described in the previous steps, then check the following:
NOTE:
It is always a good idea to try the following in order to eliminate the possibility of setup errors.
• Turn off the printer and then again,
• Delete and recreate the print server and create a new print queue in order to eliminate the
possibility of setup errors.
(1) The problem may be the result of mismatched or duplicate IP address. Verify that the IP
address is correctly loaded into the print server (via the configuration page). Make sure
that no other nodes on the network have this address (DUPLICATE IP ADDRESS ARE
THE BIGGEST CAUSE OF TCP/IP PRINTING PROBLEMS).
(2) If you used BRCONFIG to enter the IP address, make sure that you exited the remote
console properly with a CTRL-D or EXIT and that you turned the printer off and then again
(it may take up to two minutes for the IP address to take effect).
(3) Make sure that the TCP/IP protocol of the print server is enabled.
(4) If you used rarp, make sure that you started the rarp daemon on any workstation using
the rarpd, rarpd-a, or equivalent command. Verify that the /etc/ethers file contains the
correct Ethernet address and that the print server name matches the name in the
/etc/hosts file.
(5) If you used bootp, make sure that you started the bootp deamon on any UNIX workstation
and bootp is enabled (i.e., the “#” is removed from the bootp entry) in the /etc/bootptab file
is correctly configured.
(6) Also verify that host computer and the print server are on the same subnet, if the printer is
on a different subnet, make sure that the router is configured correctly and ensure that the
GATEWAY address is configured to match the IP address of the router.
9.4
UNIX Troubleshooting
(1) Make sure that the /etc/printcap file (if applicable) is typed in correctly. In particular,
look for missing ":" and "\" characters, because a small error anywhere in the file can have
major consequences. Also check the /usr/spool directory to make sure that you have
created a valid spool directory.
(2) If you are using a Linux operating system, the X-Window Print tool program that is
included with Linux may not properly configure the etc/printcap file for lpd operation, then
you might also edit the etc/printcap file and change the following line in the entry for the
printer.
if
:lp = /dev/null: \
then to
:lp = :\
(3) If you are using a Berkeley-based UNIX, make sure that the daemon is started on
Berkeley based systems with the command lpc start printer, where printer is the name of
the local print queue.
6-47
CHAPTER 6 TROUBLESHOOTING
(4) If you are using an AT&T-based UNIX, make sure the printer is enabled (enable printer,
where printer is the name of the local print queue).
(5) Make sure that the lpr/lpd remote line printer service are running on the host computer
(refer to your host computer documentation for information on how to do this).
(6) If you are having trouble printing more than one job at a time, try increasing the IP timeout
using the SET IP TIMEOUT command or using BRAdmin32.
(7) If text or PCL jobs are run together, try setting the service (remote printer) with EOT set to
string number 2 (<ESC>E). For example:
SET SERVICE BRN_xxxxxx_P1 EOT 2
(8) If PostScript jobs fail to print or are run together, try setting the service (remote printer)
with EOT set to string number 3 (control-D). For example:
SET SERVICE BRN_xxxxxx_P1 EOT 3
(9) If the lines of a text file are staggered, make sure that you have specified a remote printer
(rp) name of TEXT in your /etc/printcap file.
(10) If you are using Sun Solaris V2.4 or earlier, there is a bug which causes long print jobs to
fail when using a print server. If you are having trouble printing long jobs (over 1MB), add
the line mx#0 to your etc/printcap file entry.
9.5
Windows NT/LAN Server (TCP/IP) Troubleshooting
If you are having trouble printing with Windows NT or LAN Server, check the following:
(1) Make sure that TCP/IP and TCP/IP print service are installed and running on the Windows
NT system or the LAN Server file server.
9.6
Windows 95/98 Peer to Peer Print (LPR) Troubleshooting
If you are having trouble printing on a Windows 95/98 (or later) Peer to Peer network (LPR
method), check the following:
(1) Make sure that the Brother LPR Port driver is correctly installed and configured according
to the Windows 95/98 Peer to Peer chapters in the Network User’s Guide.
(2) You may find that during the installation of BLP software, the screen that prompts you for
a Port name is not displayed. This may happen on some Windows 95/98 computers.
Press the ALT and TAB keys to make it appear.

CHAPTER 6 TROUBLESHOOTING
9.7
Windows 95/98 (or later) Peer to Peer (HP JetAdmin Compatible Method)
Troubleshooting
If you are having trouble printing on a Windows 95/98 (or later) Peer to Peer network, check
the following (HP JetAdmin compatible method):
(1) If the print server does not show up under JetAdmin on a Windows 95/98 Peer to Peer
network, try removing all of the Windows 95/98 network software from the Network
Control panel and then reinstalling them as follows:
• First install the IPX/SPX-Compatible Protocol (or the TCP/IP protocol if you are using a
later version of JetAdmin), the Client for Microsoft Networks, and the network adapter
card driver.
• Install the Latest HP JetAdmin software
• Restart the system, and then add the HP JetAdmin service.
9.8
Windows 95/98/NT 4.0 Peer to Peer Print (NetBIOS) Troubleshooting
If you are having trouble printing on a Windows 95/98/NT 4.0 (or later) Peer to Peer network
(NetBIOS), check the following:
(1) Make sure that the Brother NetBIOS Port driver is securely installed and configured
according to the Windows 95/98/NT 4.0 Peer to Peer (NetBIOS) chapters. You may find
that during the installation of the port driver, the screen that prompts you for a Port name
is not displayed. This happens on some Windows 95/98/NT 4.0 computers. Press the
ALT and TAB keys to make it appear.
(2) Make sure that the print server is configured to be in the same workgroup or domain as
the test of your computers. It may take several minutes for the print server to appear in
the network neighborhood.
9.9
Internet Print (TCP/IP) Troubleshooting
(1) The first step in troubleshooting is to make sure that you have a valid E-mail connection
on both the sending PC and the receiving print server. Try sending an E-mail message
from the PC to a user at the remote site who can receive mail via the POP3 server. If this
does not work, there may be an E-mail configuration problem on the PC, on the local Email server, or on the remote POP3 server. Double check to make sure that the E-mail
parameters that you configured on the PC and on the remote print server match those
that are configured on the E-mail servers.
(2) If you can print small files OK but are having problems printing large files, the problem
may be in the e-mail system. Some E-mail systems have difficulties printing large files. If
the file does not reach its destination intact, then the problem is with the E-mail system.
(3) You can also enable the partial e-mail print facility on your client PC, this will split the email up into fragments which should then not overwhelm your e-mail server. To do this,
select the property dialog of the Brother Internet Print Port.
6-49
CHAPTER 6 TROUBLESHOOTING
9.10 Novell Netware Troubleshooting
If you cannot print from NetWare and you have checked the hardware and network as
described in the previous steps, first verify that the Brother print server is attached to the
server queue by going to PCONSOLE, selecting PRINT QUEUE INFORMATION, and then
CURRENTLY ATTACHED SERVERS. If the print server does not appear in the list of attached
servers, then check the following:
NOTE:
It is always a good idea to try followings in order to eliminate the possibility of setup errors
• Turn the printer off and then on again to force the printer to rescan the Netware queue.
• Delete and recreate the print server and create a new print queue in order to eliminate the
possibility of setup errors.
(1) If you changed the login password, you must change the password in both the Brother
print server (using the SET NETWARE PASSWORD command if you are using the
BRConfig software) or by using a web browser or the BRAdmin32 utility and in the file
server (using the PCONSOLE Print Server Information Change Password command).
(2) If you created the print queue using PCONSOLE and instead of BRAdmin32, make sure
that you have enabled at least one NetWare file server using the SET NETWARE SERVER
servername ENABLED command.
(3) Have you exceeded your NetWare user limit?
(4) Make sure that the print server name you used in PCONSOLE exactly matches the name
that is configured in the print server, and make sure it is defined as a Queue Server for
the print queue.
(5) If you are running both 802.3 and Ethernet II frames on different file servers on your
network, there is a possibility that the print server may not make a connection to the
desired file server. Try forcing the frame type to the desired one using the SET NETWARE
FRAME command from the print server remote console or using BRAdmin32.
(6) If you are using DOS CAPTURE statement and losing portions of your print job, try setting
the TIMEOUT parameter in your CAPTURE statement to a higher value (at least 50
seconds for Windows).
9.11 AppleTalk Troubleshooting
If you cannot print from an AppleTalk for Macintosh computer and you have checked the
hardware and network as described in the previous steps, then check the following:
(1) Make sure that you are running Phase 2 AppleTalk and that you have selected the correct
network interface from the Network Control Panel on the Macintosh.
(2) Make sure that the AppleTalk protocol of the print server is enabled.
(3) If you have a large network, make sure that you have the Laser Writer V8.xx or equivalent
driver, since earlier versions may cause PostScript errors. Also, verify that you get the
correct printer information when you select Printer Info from the Setup button in the
Chooser.
(4) Make sure that you have selected the correct Printer Description File (PPD) from the
Chooser (otherwise PostScript errors may result)
6-50
CHAPTER 6 TROUBLESHOOTING
(5) Verify that you have selected the correct AppleTalk zone. Because the print server gets its
zone information from router broadcasts, it may not be in the zone you expect, and will
therefore not show up in the Chooser. If this is the case, you may need to force the zone
name with the SET APPLETALK ZONE command described in Appendix A or using
BRAdmin32.
(6) Verify that the Laser Prep versions on all Macintosh computers that need to print to the
print server are the same.
(7) The NC-2010p printer server checks to see if the printer that it is connected to supports
PostScript. If the printer does not support PostScript, the AppleTalk protocol is disabled. If
your printer does not appear in the Chooser it may simply be caused by the lack of
PostScript support in the printer. For example, connecting a Brother HL-1250 printer to a
network using the Brother NC-2010p, will result in the printer NOT appearing in the
Chooser as the HL-1250 printer does not support PostScript.
9.12 Apple TCP/IP Printing (System 8.6 or later)
(1) From system 8.6 or later, Apple introduced the Desktop Printer Utility. This utility allows
TCP/IP printing from an i-Mac/G3 or later Macintosh.
(2) From the “Internet Printer” dialogue, please ensure that you enter the correct service
name in the “Queue” option. For example, for NC-3000 series network cards enter
BRN_xxxxxx_P1_AT (where xxxxxx is the last six digits of the MAC address of the NC3000 series card). For NC-2000 series network cards enter BRO_xxxxxx_P1_AT (where
xxxxxx is the last six digits of the MAC address of the NC-2000 series card).
(3) This method of printing requires that the printer supports PostScript. If your printer does
not support PostScript printing. Please consult your printer manual to see if your printer
supports PostScript.
9.13 Web Browser Troubleshooting (TCP/IP)
(1) If you can not connect to the print server using your web browser it may be worth
checking the Proxy Settings of your browser. Look in the Exceptions setting and if
necessary, type in the IP address of the print server. This will stop your PC from trying to
connect to your ISP or proxy server every time you wish to look at the printer server.
(2) Make sure that you are using the proper Web Browser, we recommend Netscape
Navigator version 3.0 or later/ Microsoft Internet Explorer version 3.02a or later.

4. HOW TO KNOW DRUM UNIT LIFE & PAGE COUNTER
If you want to know the drum unit life or the number of printed pages, you should print out the
Print Configuration page for the HL-1240/1250/1270N printer, or print out the Test Print page
for the HL-1030.
NOTE:
The page counter, drum counter and drum unit life bar are NOT printed on the Print
Configuration page for some models. For those models, use the Printer Information tool
which indicates the page counter, etc. on the PC screen, referring to Section 3 ‘Printer
Information’ in APPENDIX 5.

How to Read the Drum Unit Life
The drum unit life is shown by the bar at the bottom of Print Configuration or Test Print as

information
Fig. A-3
The drum unit life is based on the page counter. If the average number of drum rotations is
more than the number of drum rotations in non-continuous printing, however, the drum unit life
is counted by the number of drum rotations.
Since the drum counter printed in Print Configuration (HL-1240/1250/1270N) or Test Print (HL1030) is an actual page counter after a new drum unit is replaced, the drum unit life may be
different from the drum counter.
For details on the difference between the drum unit life and drum counter, refer to the drum unit
life calculation below;
<How to calculate drum unit life>
**Printing time for 1 page/job in discontinuous printing = 14 seconds
(Page counter reduced by the number of drum rotations) = (Time of motor rotation) ÷ (14 sec.)
Example:
Cold start (Idling for 6 sec.)
Hot start
Page counter
1 page/job
(6 + 14) / 14 = 1.43
14 / 14 = 1
1
2 pages/job
(6 + 14 + 5) / 14 = 1.79
(14 + 5) / 14 = 1.36
2
16 pages/job
(6 + 14 + 5 x 15) / 14 = 6.79
(14 + 5 x 15) / 14 = 6.36
16
If printing 1 page per job with cold start, the drum unit life is decreased earlier.

APPENDIX
APPENDIX
7. PAPER CASSETTE INFORMATION (FOR EUROPE ONLY)
The A4 size 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 HL1030/1240/1250/1270N printer has a
plastic rib on the paper tray cover.
(2) The plastic rib is removed from the tray
cover for the paper cassette supplied with
the LT-400, (optional Lower Tray Unit) as
shown on the right;
Paper tray cover
Plastic rib
Cutting position
Fig. A- 15
(3) If the optional LT-400 Lower Tray Unit is installed onto the HL-1250/1270N printer, it is
necessary to exchange the cassette supplied with the LT-400 Unit with the upper cassette
already fitted into the printer. Install the cassette originally fitted in the printer into the LT400 Unit.
Failure to do so will cause paper jams as the paper cannot be fed from the lower cassette
to the printer body because the plastic rib on the paper tray cover is blocking the paper
path.
(4) For paper cassettes supplied as spare parts, the plastic rib has been cut off so that you
can use it as both an upper cassette and lower cassette.

APPENDIX 23. DIFFERENCES BETWEEN OLD & NEW VERSIONS OF HVPS &
ENGINE PCB
The high-voltage power supply PCB and engine PCB have been upgraded since the
production in the middle of September, 1999 in order to improve print quality. In accordance
with the change, the T/R electrode helical spring and plastic chute have been also changed.
This section describes the differences between the old and new versions of those parts so that
the service technician can identify the old or new version at a glance.
High-voltage power supply PCB / Engine PCB
Check the pin number of the connector on one of the high-voltage power supply PCB and
engine PCB, which connects those two PCBs. While the old version has 7 pins, the new
version has 8 pins. The figure below indicates the connector on the Engine PCB.
Old version
New version
8 pins

Engine PCB
Fig. A- 16
T/R electrode helical spring / Chute
The size of the T/R electrode helical spring is different between the old and new versions.
While the spring is assembled onto the big boss on the plastic chute for the old version, it is
assembled onto much smaller boss on the chute for the new version. Note that the assembled
position of the spring is also different.
