NT 4.0 and
Windows
2000/XP Home Edition/XP Professional/XP Professional x64 Edition 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. 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 CD-
ROM 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.

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.

NOTE:
•
The print speed may vary according to conditions, such as paper size and paper tray.
•
When a smaller size paper than A4 or Letter is printed, the temperature on both edges of the fuser unit is much higher than the temperature on the center of the unit where the paper is fed depending on the setting or model. Therefore, the print speed is slowed in order to decrease the temperature on the edges after the specified time, it is maximum print speed when you first start printing.
•
The actual print speed varies depending on the paper size.

CHAPTER 2 THEORY OF OPERATION
The plate ASSY in the paper tray is pushed up with the motor drive and not with the spring in order to maintain the constant paper feeding performance regardless the number of sheet remained in the tray.
When the paper tray (Tray1 cassette) is installed into the printer, the lift gear 46 is rotated, and the motor drive is transmitted to the plate ASSY so that it is pushed up.

After the paper top position is detected by the regist actuator front, the paper, separated into individual sheets by the separation roller, is fed further for a specified time, and the paper top position reaches the regist roller so that the paper skew is adjusted. Then, the register solenoid is turned off, the paper feed roller starts turning, and the paper is fed to the transfer roller in the drum/toner ASSY.

CHAPTER 2 THEORY OF OPERATION
3.3.4 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 developer 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 developer roller. The toner adheres to the developer roller and is conveyed to the exposure drum at an even thickness controlled by the blade. The toner is nipped between the developer roller and the drum and developed onto the latent image on the drum. The electrostatic field between the drum and the developer roller, which is DC-biased from the high-voltage power supply, creates the electrostatic potential to attract toner particles from the developer roller to the latent image area on the drum surface.

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 fuser 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.

After the printing image on the exposure drum is transferred onto the paper, the paper is fed to the fuser unit to fix unfixed toner onto the paper by the heat roller and the pressure roller in the fuser unit.
Afterwards, the paper is ejected from the fuser unit. The paper eject actuator detects whether the paper is ejected correctly or not.
After the paper exits from the heat roller, the paper is turned by the back cover and ejected face down into the top output tray through the eject roller ASSY.

After the paper exits from the eject roller ASSY with the front of sheet printed, the eject roller
ASSY rotates conversely and feeds the paper to the duplex tray, where the paper skew is adjusted.
Afterwards, the paper is ejected from the duplex tray to the path through the regist roller and the transfer roller to the transfer block in the drum unit again for process of printing on the back of sheet.

3.3.8 Paper feeding from the MP tray
The separation roller is connected with the feed roller through the gear in the MP roller holder
ASSY. When the separation roller is driven, therefore, the feed roller is also driven. At this time, the recording paper is drawn out of the MP tray by rotation of the feed roller contacted with the recording paper. The drawn recording paper is separated into individual sheets by the separation roller.

3.4.1 Toner life end mode
A new toner cartridge can print approximately 3,500 (standard toner) or approximately 7,000
(high yield toner) A4 or Letter size single-sided pages at 5% coverage. In the case of low-duty printing, “Toner Life End” is indicated by lighting Toner LED (HL-5240/5250DN) or “TONER
LIFE END” message appears on the LCD panel (HL-5270DN/5280DW) before the toner runs out because the developer roller surface or other toner sealing is worn out due to a rotation of the rollers. The upper limit of the drum rotation is 46,200 = 4,200 sheets x 11 rotations
(standard toner), 92,400 = 8,400 sheets x 11 rotations (high yield toner).

3.4.2 New toner detection mechanism
(1) The main motor will drive gear (4) through the interconnection of other gears.
(2) When gear (4) is rotated, rib A on that gear will push against the new toner actuator; the new toner sensor will detect the actuator motion, and the toner sensor detects that a new toner cartridge has been installed.
(3) The standard toner cartridge has Rib A and Rib B on gear (4).
When the toner actuator is pushed twice, the two signals that are generated by the new toner sensor, tell the machine that a standard toner cartridge has been installed.
(4) The high yield toner cartridge only has Rib A on gear (4).
When the toner actuator is pushed once, the signal that is generated by the new toner sensor, tell the machine that a high yield toner cartridge has been installed.

CHAPTER 2 THEORY OF OPERATION
When the new toner detection switch detects that the toner cartridge is replaced with a new one, the developing bias voltage is initialized at the same time.
The toner used for the printer has a property that print density is light first and gradually darker in the course of usage. The developing bias controls the toner property so that the print density is constant from first to last.

[Density]
[Voltage]
Print density
[Density]
[Voltage]

Bias voltage
[Used toner amount] [Used toner amount]
To obtain a print result of a constant density all the time, the printer counts the number of print pages immediately after the toner cartridge is replaced and changes the bias voltage according to the accumulated number of prints with the toner cartridge.
The bias voltage is changed with the steps described below:
(1) When the new toner sensor detects that the toner cartridge is replaced with a new (full) one, the developing bias is set to 400V (initialized).
(2) After that, the bias voltage is stepped down according to the number of prints.
3.4.3 Counter reset during indication of “Toner Life End”
The counter resetting method during indication of “Toner Life End” depends on the cause of toner life end and the condition of the inserted toner cartridge. Refer to the following table for details.

3.5.1 Charging
The drum is charged to approximately 900V 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 exposure drum is grounded.

Corona wire

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

1. The laser beam radiated from a laser diode inside the laser unit are concentrated into a constant width by a slit in the CO lens cell and then reflected by a polygon mirror rotating at high speed.
2. The laser beam reflected by the polygon mirror are refracted by the f-theta lens and radiated from the right through to the left end of the reflection mirror as the polygon mirror rotates. At this time, blur of the vertical direction of the laser beam by inclination of a polygon mirror is corrected by passing a Toric lens.

CHAPTER 2 THEORY OF OPERATION
3. The laser beams reflected by the reflection mirror go straight toward the exposure drum below it, then expose the exposure drum.
The area exposed to the laser beam is the image to be printed. The surface potential of the exposed area is reduced, forming the electrostatic image to be printed.

3.5.3 Transfer
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 roller 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 exposure drum.

1. INTRODUCTION
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.
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 damp. [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 3.6 “Paper” in Chapter 1 .
Check if :
(HL-5240/5250DN)
•
The LEDs on the printer control panel indicate “Toner Life End”. If the LEDs indicate
“Toner Life End”, replace the toner cartridge with a new one.
(HL-5270DN/5280DW)

CHAPTER 4 TROUBLESHOOTING
(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 exposure drum is cold, the electrical resistance of the photosensitive layer is increased, making it impossible to obtain the correct contrast when printing.
•
Condensation on the corona unit may cause corona charge leakage.
•
Condensation on the pressure 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 Warning for Maintenance Work
To avoid creating secondary problems by mishandling, follow the warnings below during maintenance work.
WARNING
•
Always turn off the power switch and unplug the power cord from the power outlet before accessing any parts inside the printer.
•
Some parts inside the printer are extremely hot immediately after the printer is used.
When opening the front cover or back cover to access any parts inside the printer, never touch the shaded parts shown in the following figures.

DRUM
< How to Read the Drum Unit Life >
The drum unit life is shown by the band graph at the center of Print Settings;
•
It initially indicates 100% and gradually decreases.
• It indicates 0% when the
Drum
LED is blinking.
•
It stays at 0% even if further printing is done.
< The difference of the Drum Unit Life and the Drum Counter >
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 Settings 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;
7-12
Confidential
HL-5240/5250DN/5270DN/5280DW SERVICE MANUAL
< How to calculate Drum Unit Life >
The number of drum rotations per one page printing is about 11 rotations.
(Page counter reduced by the number of drum rotations) =
(the number of drum rotations) ÷ 11
- The number of drum rotations per one page printing continuously = 3.6 rotations.
- The number of drum rotations while warming-up = 9 rotations
Example:
The number of pages calculated from drum rotations
Cold start (page) Hot start (page)
1 page/job (9 + 11) / 11 = 1.82
2 pages/job (9 + 11 + 3.6) / 11 = 2.15
11 / 11 = 1
(11 + 3.6) / 11 = 1.33
18 pages/job (9 + 11 + 3.6 x 17) / 11 = 7.38 (11 + 3.6 x 17) / 11 = 6.56
If printing 1 page per job with cold start, the drum unit life is decreased earlier.
(ii) Counter information, history information
The counter and history information related to the following term are included. When it reaches the maximum count, each term is no longer counted.
•
Page counter
The total number of pages printed. The maximum count is 1 million pages.
•
Coverage on the Letter-size paper
Average printing rate. The average of the total printed area against the printable are on the Letter-size paper. The coverage is calculated when up to 1 million pages are printed, and it is not updated after this.
It is not printed on the Print Settings by default. (It is printed on the maintenance sheet by default.)
•
Total pages printed (TRAY)
The number of times that each of the Tray1, Tray2, Tray3, MP tray and Duplex tray is used. (For the Duplex tray, the number of times is printed only for the models supporting the Duplex tray, and it is not printed for HL-5240.)
The maximum count for each item is 1 million times.
The information above is not cleared when replacing the PF kit.
•
Total pages printed (PAPER)
The number of A4/Letter, A4Long/Legal/Folio, B5/Excutine, Envelope,
A5 and other paper types used. The maximum count for each item is
1 million times.
•
Total paper jams
The number of paper jam occurrence in each of the Tray1, Tray2,

(10) Sleep Mode Indication (OFF/Dimmed)
This is to select whether the
Status
LED is turned off completely or lit in green with low light intensity during the Sleep mode. Whenever you switch this mode, the setting is changed over from the present one to the other. When you take your finger off from this switch, the
Status
LED is lit in 100% light intensity or low light intensity according to the setting so that you can verify the present setting.
(11) Sleep Mode Setting (ON/OFF)
This is to allow you to turn on and off the sleep mode of the printer. The default setting is
ON. The machine automatically goes back to the ready state after the operation is completed.
(12) Developer Roller Counter Reset 1 (For the standard toner)
(13) Developer Roller Counter Reset 2 (For the high yield toner)
Since print density is likely to become darker as toner is getting older, the developing bias is lowered by degrees according to the number of prints so that an almost fixed density can be maintained from the start of the use of brand-new toner to the end of it. The value of the developing bias is printed on the maintenance sheet. The developing bias is a parameter which depends on the developing assembly, so it needs to be reset when the developing assembly is replaced. At that time, the developing roller counter reading is also reset. This mode is to enable to execute these operations (equivalent to those done when the developing assembly is replaced) manually from the service mode.
(14) Fixed USB Speed
This allows you to switch the setting of Full fixed / Auto switching (HIGH/FULL) of the
USB speed. Whenever switching, the current setting is changed to the other one.
The default setting is Auto switching.
