IMPORTANT - For Your Safety To ensure safe operation the three-pin electrical plug supplied must be inserted only into a standard three-pin power point which is properly grounded through normal household wiring. Extension cords used with the equipment must be three-pin plug type and correctly wired to provide proper grounding. Incorrectly wired extension cords may cause personal injury and equipment damage. The fact that the equipment operates satisfactorily does not imply that the power is grounded and that the installation is completely safe. For your safety, if in any doubt about the effective grounding of the power, consult a qualified electrician. Disconnect device This printer must be installed near a power outlet, which is easily accessible. In case of emergencies, you must disconnect the power cord from the power outlet in order to shut off power completely. Geräuschemission / Acoustic Noise Emission (For Germany Only) Lpa < 70 dB (A) DIN 45635-19-01-KL2 ix USER'S GUIDE IMPORTANT - Wiring Information (For U.K. only) If the power cord supplied with this printer is not suitable for your electrical outlet, remove the plug from the mains cord and fit an appropriate three pin plug. If the replacement plug is intended to take a fuse then fit the same fuse as the original. If a moulded plug is severed from the power cord then it should be destroyed because a plug with cut wires is dangerous if plugged into a live socket outlet. Do not leave it where a child might find it. In the event of replacing the plug fuse, fit a fuse approved by ASTA to BS1362 with the same rating as the original fuse. Always replace the fuse cover. Never use a plug with the cover omitted. WARNING - THIS PRINTER MUST BE PROPERLY EARTHED. The wires in the mains cord are coloured in accordance with the following code: Green and yellow: Blue: Brown: Ground Neutral Live The colours of the wiring in the power lead of this printer may not correspond with the markings which identify the terminals in your plug. If you need to fit a different plug, proceed as follows. Remove a length of the cord outer sheath, taking care not to damage the coloured insulation of the wires inside. Cut each of the three wires to the appropriate length. If the construction of the plug permits, leave the green and yellow wire longer than the others so that, in the event that the cord is pulled out of the plug, the green and yellow wire will be the last to disconnect. Remove a short section of the coloured insulation to expose the wires. The wire which is coloured green and yellow must be connected to the terminal in the plug which is marked with the letter "E" or by the earth symbol or coloured green or green and yellow. The wire which is coloured blue must be connected to the terminal which is marked with the letter "N" or coloured black or blue. The wire which is coloured brown must be connected to the terminal which is marked with the letter "L" or coloured red or brown. The outer sheath of the cord must be secured inside the plug. The coloured wires should not hang out of the plug. x CHAPTER 1 INTRODUCTION CHAPTER 1 INTRODUCTION ABOUT THE GUIDEBOOKS Finding Out How to Use the Printer You have two guidebooks for this printer.

Features This printer has the following features: t 600 dpi Resolution and 6 ppm Printing Speed True 600 dots per inch (dpi) with microfine toner and six pages per minute (ppm) printing speed (A4 or Letter paper). The resolution and printing speed may vary depending upon document complexity. t Versatile Paper Handling The printer has a multi-purpose sheet feeder and straight paper path mechanism. Using this mechanism, you can load A4, letter, legal, B5, A5 and executive sizes of paper, and various types of paper including envelopes, postcards, organizer paper, and your custom paper size. The multi-purpose sheet feeder also allows manual paper loading, so you can also use labels and transparencies. t Enhanced Printing Performance and User-Friendly Operation for ® Windows The dedicated printer driver and TrueTypeTM-compatible fonts for ® Microsoft Windows 95 and Windows 3.1 are available on the floppy disk 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 saving mode, custom paper size, sleep mode, gray scale adjustment, resolution and so forth. You can easily set these print options through the Printer Setup Menu within the Windows Control Panel. CHAPTER 1 ­3 USER'S GUIDE t Remote Printer Console Program for DOS (For HL-730/730Plus series Only) The utility program, Remote Printer Console (RPC), is available on a floppy disk supplied with your printer. When you operate your computer in the DOS (Disk Operating System) environment, this program allows you to easily change the default settings of the printer such as fonts, page setup, emulations and so on. 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. t Popular Printer Emulation Support (For HL-730/730Plus series Only) This printer supports three popular printer emulation modes, HP LaserJet IIP, 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 printer in the 300 dpi resolution mode. The printer also supports auto-emulation switching between HP and Epson or HP and IBM. If you want to select the printer emulation, you can do it using the Remote Printer Console Program. t Printer Status Monitor with Bi-directional Parallel Interface The printer driver can monitor your printer's status using bidirectional parallel communications. A high quality 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. For example: when your printer is out of paper, the dialog box will display "Paper Empty" and instructions for the proper corrective action. t Optional Apple Macintosh Interface (For HL-730/730Plus series Only) An optional Apple Macintosh serial interface is available, which allows your printer to be connected to Apple Macintosh computers. With this option, you can use your printer with both an IBM PC, or compatible, and an Apple Macintosh at the same time. This optional interface board can be used as an RS-422A interface for Macintosh or an RS-232C serial interface for an IBM PC or compatible. ® CHAPTER 1­4 CHAPTER 1 INTRODUCTION t Enhanced Memory Management The printer provides its own data compression technology in the 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 larger fonts, with the printer's standard memory. t Environment-Friendly Economy Printing Mode This feature will cut your printing cost by saving toner. It is useful to obtain 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) When the printer is not used for a certain amount of time, sleep mode automatically reduces power consumption. The printer consumes less than 7 W 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 approximately 2,200 pages, which is cost effective and ecologically friendly. (In USA, Canada and some other areas the printer is supplied with a starter toner cartridge which must be replaced after 1,000 pages.) The actual number of pages printed with each toner cartridge may vary depending on your average type of print job.

( ) Fig. 2-5 Moving the Paper Guide and Closing the Feeder Note If the multi-purpose sheet feeder runs out of paper when you try to print, the Alarm and Paper lamps blink to alert you to a paper empty error. You have to load paper in the feeder and push the panel switch to cancel the alarm and continue printing. If paper jams in the printer, the Alarm and Paper lamps also blink. If the error is a paper jam, clear it referring to "PAPER JAMS" in Chapter 6. CHAPTER 2 ­6 CHAPTER 2 PAPER HANDLING Two Side Printing (Manual Duplexing) The supplied printer driver for Windows 95 or Windows 3.1 enables manual duplex printing. For more information about settings, see the help text in the printer driver. The printer prints all the even numbered pages on one side of the paper first, and then prints all the odd pages on the reverse side of the paper. When you have finished printing the even numbered sides of the paper, the driver instructs you to re-insert the paper by a pop-up message on the computer screen. Follow the instructions on how to reinsert the paper. Note · Before re-inserting the sheets, you have to straighten them, or you will get paper errors. · The use of very thin or very thick paper is not recommended. · If you encounter a double feeding error, we recommend that you hold all sheets of paper except the front sheet while the paper is feeding. Fig. 2-6 Notes for Manual Duplexing Note When you use the Manual Duplex function, it is possible that paper jams may occur or print quality might not be satisfactory. CHAPTER 2 ­7 USER'S GUIDE MANUAL FEED SLOT The multi-purpose sheet feeder also has a manual feed slot. You can manually load paper sheet by sheet from this slot. You do not need to remove paper from the multi-purpose sheet feeder when using the manual feed slot. t When you load one sheet of paper manually: You do not need to choose manual feed in the Setup dialog box of your printer driver. Holding the selected size of paper in the selected orientation (Portrait or Landscape), place the side of the paper you wish to print on face down into the manual feed slot. Align the paper at the center of the manual feed slot, and be sure to insert it all the way. ( ) Move the paper guide of the manual feed slot to the paper width you are using. ( ) Fig. 2-7 Moving the Paper Guide t When you load more than one sheet of paper manually: Open the Setup dialog box of the supplied Windows printer driver and choose Manual Feed in the Paper Source section. Follow the above instructions to load the first page. The printer automatically starts printing. After the first page is printed, the dialog box appears and prompts you to load the next page. Load a sheet and choose OK to resume printing. Repeat these steps until you have finished printing all the pages. ! Caution If bi-directional communication is not operational between the printer and the computer, such as when the printer is shared on a network, the dialog box will not appear to load the next page. Manual paper feeding is not recommended when your printer is attached to a network. CHAPTER 2 ­8 CHAPTER 2 PAPER HANDLING Note · Insert paper firmly into the manual feed slot. · Be sure to load sheet by sheet when using the manual feed slot. CHAPTER 2 ­9 USER'S GUIDE OUTPUT TRAY AND PAPER SUPPORT WIRE The printer ejects paper with printed surfaces face down into the output tray at the front of the printer. When the output tray is closed, the ejected paper comes out sheet by sheet through the slit at the front. When you open the tray, sheets can be stacked on the tray. Follow these steps to open the output tray: 1. Pull the top of the tray down (). 2. Extend the extension support wire (). Fig. 2-8 Opening the Output Tray and Extending the Extension Support Wire You can stack up to 100 sheets in the output tray. · When you use transparencies, remove each sheet immediately after printing. Stacking sheets may cause paper curled or paper jam. · Continuous printing with the output tray closed may cause condensation inside the output tray. ! Caution CHAPTER 2 ­10 CHAPTER 3 CONTROL PANEL CHAPTER 3 CONTROL PANEL LAMPS AND SWITCH This section refers to the following lamps and switch on the printer control panel. Dru m Alar m Re Pap ady er D Tonata er Fig. 3-1 Lamps and Switch on Control Panel Note When the power switch is off or the printer is in sleep mode, all lamps including the Ready lamp are off. Ready (Paper) Lamp The Ready lamp indicates the current status of the printer. Lamp Off r Blinking r£q Blinking r£q On q This lamp also works as the Paper lamp with the Alarm lamp. They blink simultaneously to indicate a paper error. See "Operator Calls" in Chapter 6. Printer status The power switch is off or the printer is in sleep mode. If the printer is in sleep mode, it will wake up automatically when it receives data or you press the control panel switch. The printer is warming up. (Blinking at 1 second intervals) The printer is cooling down and stops printing until the printers internal temperature lower. (Blinking at 2 seconds intervals) The printer is ready to print. CHAPTER 3 ­1 USER'S GUIDE Data (Toner) Lamp The Data lamp indicates the current status of the print data process. Lamp Off r Blinking r£q On q The printer is receiving data from the computer or the printer is processing data in memory. Print data remains in the printer memory. If the Data lamp is on for a long period of time and nothing has printed, you need to press the switch to print the remaining data. Printer status The printer has no print data. This lamp also works as the Toner lamp with the Alarm lamp. They blink simultaneously to indicate a toner error. See "REPLACING THE TONER CARTRIDGE" in Chapter 5 and "Operator Calls" in Chapter 6. Drum Lamp The Drum lamp indicates the drum unit is nearly at the end of its life. Lamp Off r On q The drum unit is nearly at the end of its life. Installing a new drum unit turns off this lamp. See "REPLACING THE DRUM UNIT" in Chapter 5. Printer status The drum unit can be used. Alarm Lamp The Alarm lamp blinks to indicate a printer error status such as "Cover Open" and "Memory Full." If any other error occurs, the printer indicates the error by blinking the Alarm lamp with another lamp or by printing an error report. Note The Ready, Data and Drum lamps are used to indicate printer errors with the Alarm lamp. See "ALARM INDICATIONS AT A GLANCE" in Chapter 6 and take corrective action for the error. CHAPTER 3 ­2 CHAPTER 3 CONTROL PANEL Switch If you press the switch during printing, the printer immediately stops printing and ejects the paper. It is recommended that you wait until the page has finished printing, then press the switch, otherwise you will lose data on the page. If the printer is in sleep mode, pressing the switch wakes it up into the ready state. If the Data lamp is on, press the switch. The printer prints any data remaining in the printer memory: this operation is called "Form Feed." If an error occurs, the printer will recover from some errors automatically. If the error does not clear automatically, press the switch to clear the error and continue printer operation. Other Control Features The printer has the following useful features: Sleep Mode When the printer does not receive data for a certain period of time (timeout), it enters sleep mode. Sleep mode acts as though the printer was turned off. The default time-out is 5 minutes. While the printer is in sleep mode, all the lamps 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 switch 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. · Sleep mode allows the print engine to cool, so the temperature of your room and how long the printer has been in sleep mode affects the warm-up time. This warm-up time can take up to 20 seconds. The Ready lamp blinks to indicate that the printer is warming up. · You can change the time out for the sleep mode with the supplied printer driver or Remote Printer Console program. Refer to the Help section in the printer driver or RPC program for more information about the sleep mode setting.

Connecting the Serial Interface Cable Note This section is only for printer models which have had the serial interface installed. You need a serial interface cable with an 8-pin, DIN-type connector to connect your printer and computer. Note · Consult your dealer for a serial interface cable. · If you are a Macintosh user, you can easily find the necessary cable at a local computer store. Look for Apple serial cables labeled as "Macintosh to ImageWriter IITM or "Macintosh to Personal LaserWriterTM 300" or the "Apple System Peripheral 8 Cable". Do not purchase a serial cable labeled as "Straight-through" or "LocalTalk." · If you are a PC user, you need to purchase a special serial cable from your dealer. If you have a 9-pin connector on your computer, look for a cable labeled "IBM AT to ImageWriter II" cable. If you have a 25-pin connector, look for a cable labeled "DB25 to ImageWriter II." These cables most likely would be found in the Apple Macintosh section at your computer dealer. For more information about the interface specification, consult your dealer. CHAPTER 4 ­4 CHAPTER 4 OPTIONS You can connect a parallel and a serial interface cable at the same time. The auto interface selection function allows you to share the printer with two computers. To do this, connect the parallel interface cable and then connect the serial interface cable as follows: 1. Make sure that the power switch is turned off. ! Caution Be sure to turn off the power switch before connecting or disconnecting the interface cables, or the printer may be damaged. 2. Insert and secure the parallel interface connector into the parallel interface port of your printer. 3. Insert and secure the serial interface connector into the serial interface port of your printer. 4. Turn on the power switch. CHAPTER 4 ­5 USER'S GUIDE MEMORY BOARD Additional memory is useful and maybe necessary if you printing a very complex document. Since Brother Printing Solution for Windows relies on effective data compression to `squeeze' a large print job into a smaller space, there are times when data compression cannot squeeze a complex 600 dpi document into a smaller space and a resulting "Print Overrun" error message may occur. When this occurs, you may choose to purchase additional memory, or make changes to your printer driver settings (such as reduce print resolution from 600 to 300 dpi, or change Half Tone setting to Line Art or Photo Graphics). The HL-720 series printer has 0.5 MB of memory as standard. The memory capacity can be expanded up to 2 MB with an optional memory board. Only one size of memory board is available as an option, giving 1.5 MB memory expansion. The HL-730 series printer has 0.5 MB of memory as standard. The memory capacity can be expanded up to 2 MB with an optional memory board. Two sizes of memory boards are optionally available: 1 MB memory expansion (giving you a total of 1.5 MB) or 1.5 MB memory expansion (giving you a total of 2 MB). Only one memory board can be installed, so select your board carefully according to your printing needs. The HL-730Plus series printer has 1.0 MB of memory as standard. The memory capacity can be expanded up to 2 MB with an optional memory board. Only one size of memory boards is available as an option, giving 1.0 MB memory expasion. 1.0 MB N/A MB-110 MB-110 1.5 MB MB-215W MB-115 N/A HL-720 series HL-730 series HL-730Plus series These memory options may be purchased directly from Brother or from an authorized Brother dealer/retailer. The memory board is installed onto the main controller board inside the printer. For the installation details, please see the Instruction guide which is provided with the memory board. CHAPTER 4­6 CHAPTER 5 MAINTENANCE CHAPTER 5 MAINTENANCE REPLACING THE TONER CARTRIDGE The printer can print approximately 2,200 pages with one toner cartridge. When the toner cartridge is running low, the Alarm and Data (Toner) lamps blink once every 5 seconds to indicate toner low. In USA, Canada and some other areas the printer is supplied with a starter toner cartridge which must be replaced after 1,000 pages. Note · Actual page count will vary depending on your average document type. (i.e.: standard letter, detailed graphics, etc.) · It is recommended that you always keep a new toner cartridge ready for use for when you get the toner low warning. · Discard the used toner cartridge according to local regulations. If you are not sure of them, consult your local dealer. Be sure to seal up the toner cartridge tightly so that toner powder does not spill out of the cartridge. Do not discard used toner cartridges together with domestic rubbish. · It is recommended that you clean the printer when you replace the toner cartridge. See "CLEANING THE PRINTER" in this chapter. Dru Ala rm m Re Pap ady er D Tonata er Fig. 5-1 Toner Low and Empty Indication ! Caution You may print approximately 100 pages after the first toner low indication. Both Alarm and Data (Toner) lamps will blink continuously to indicate that the toner is empty. Once this indication appears, your printer cannot resume printing until you have installed a new toner cartridge. CHAPTER 5 ­1 USER'S GUIDE !

CHAPTER 5 ­5 USER'S GUIDE REPLACING THE DRUM UNIT The printer uses a drum unit to create the print images on paper. If the Drum lamp is on, it indicates the drum unit is nearly at the end of its life. We recommend you prepare a new drum unit to replace the current one. Even if the Drum lamp is on, you may be able to continue to print without replacing the drum unit for a while. If there is a noticeable deterioration in the output print quality even before the Drum lamp lights, then the drum unit should be replaced. Dru m Ala Re Pap ady er D Tonata er rm Fig. 5-9 Drum Unit Nearly at the End of its Life · When removing the drum unit, handle carefully as it may contain toner. · You should clean the printer when you replace the drum unit. See "CLEANING THE PRINTER" in this chapter. Note The drum unit is a consumable, and it is necessary to replace it periodically. There are many factors that determine the actual drum life, such as temperature, humidity, type of paper and toner that you use, the number of pages per print job, etc.. The drum life is estimated at approximately 20,000 pages at 20 pages per job and 8,000 pages at 1 page per job. The actual number of pages that your drum will print may be significantly less than these estimates. Because we have no control over the many factors that determine the actual drum life, we cannot guarantee a minimum number of pages that will be printed by your drum. For best performance, use only genuine Brother toner, and the product should only be used in a clean, dust-free environment with adequate ventilation. !
