The paper cassette can hold A4, letter, B5, Executive A5 and A6 sizes of paper. The manual feed slot allows manual paper loading sheet by sheet so you can use a variety of types and sizes of paper. Front Operation Basic operation of the printer can be controlled from the front panel. Enhanced Printing Performance and User-Friendly Operation for Windows The dedicated printer driver for Microsoft Windows 95/98/Me, and Windows NT 4.0/2000 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. If an error occurs, the printer status monitor will appear to let you know what to correct. If you have turned on the interactive Help ( Windows 95/98/Me only) you can get visual guidance on your PC screen on the actions in the event of certain printer errors. 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 into the task tray when this printer driver is selected. You can change the settings by clicking on the icon with the right mouse button.

CHAPTER 1 GENERAL
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, iMac and Power Macintosh G3 using USB with HL-1440/1450/1470N 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 CDROM supplied with the printer. Remote Printer Console Program for DOS (for HL-1440/1450/1470N 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-1440/1450/1470N only) These printers support the following printer emulation modes; The HL-1440 supports HP LaserJet IIP.The HL-1450/1470N supports HP LaserJet 6P (PCL6), PostScript Level2 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-1450/1470N 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-1450/1470N 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 This feature will cut your printing cost by saving toner. It is useful for obtaining draft copies for proof-reading. You can select the economy modes through the Windows printer driver supplied with your printer. 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-1230), 6W (HL-1440/1450) or 12W (HL-1470N) when in sleep mode. 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 effective and ecologically friendly.

Pressure plate Fig. 3-29
Separation pad
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. And Eject actuator 2 protects from accordion jam in the fixing unit when the tip of the paper doesn't eject from the unit. 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
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 Exposure stage 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.
