CHAPTER 1 TROUBLESHOOTING  
1.  
INTRODUCTION  
Troubleshooting is the countermeasure procedures that the service personnel should follow if  
an error or malfunction occurs with the machine. It is impossible to anticipate all of the  
possible troubles which may occur in future and determine the troubleshooting procedures,  
so this chapter covers some sample troubles. However, those samples will help the service  
personnel pinpoint and repair other defective elements.  
1.1 Precautions  
Be sure to observe and follow all the precautions to prevent any secondary problems from  
happening during troubleshooting.  
(1) Always turn off the power and unplug the power cable before removing any covers or  
PCBs, adjusting the machine and so on. If you need to take voltage measurements with  
the power switched on, take the greatest of care not to receive an electric shock.  
(2) When connecting or disconnecting cable connectors, make sure that you hold the  
connector body and not the cables.  
(3) Electronic devices are sensitive to static build up; make sure that you touch a metal  
portion of the machine to discharge yourself before accessing the PCBs.  
Handle PCBs with care when repairing them.  
(4) Follow the warning by all means.  
The fuser unit becomes extremely hot during operation. Wait until it has cooled down  
sufficiently before replacing consumable items. DO NOT remove or damage the  
caution label located on or around the fuser.  
(5) Verify again that the repaired portion works properly.

1.2 Initial Check  
Check the following items before attempting to repair the machine.  
■ Operating Environment  
(1) Put your machine on a flat, stable surface such as a desk that is free of vibration and  
shocks.  
(2) Use the machine in a well-ventilated room; use the machine within the following ranges  
of temperature and humidity: temperature between 10°C and 32.5°C (50°F to 90.5°F),  
and the relative humidity is maintained between 20% and 80%.  
(3) The machine is not exposed to direct sunlight, excessive heat, moisture, or dust.  
■ Power Supply  
(1) The AC input power supply described on the rating plate of the machine should be within  
±10% of the rated voltage.  
(2) The AC input power supply is within the regulated value.  
(3) The cables and harnesses are connected correctly.  
(4) The fuses are not blown.  
■ Paper  
(1) A recommended type of paper is being used.  
(Refer to “2.6 Paper”, Reference 1 of the Service Reference Manual.)  
(2) The paper is not damp.  
(3) The paper is not short-grained paper or acid paper.  
■ Consumable Parts  
(1) The drum unit (including the toner cartridge) is installed correctly.  
■ Others  
(1) Condensation  
When the machine is moved from a cold place into a warm room, condensation may  
occur inside the machine, causing various problems as listed below.  
• Condensation on the optical surfaces such as the scanner window, 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 charge unit may cause corona charge leakage.  
• Condensation on the plate and separation pad may cause paper feed failures.  
If condensation has occurred, leave the machine for at least 2 hours to allow it to reach  
room temperature.  
If the drum unit is unpacked soon after it is moved from a cold place to a warm room,  
condensation may occur inside the unit which may cause incorrect images. Instruct the  
end user to allow the unit to come to room temperature before unpacking it. This will take  
one or two hours.

■ Rewriting the firmware (Main Program)  
<Installing the maintenance printer driver>  
To identify terminals connected via USB interface, the PC requires the corresponding  
virtual USB devices to be implemented by driver. If you connect any number of the  
machine to your PC, therefore, the same number of virtual USB devices will be  
automatically configured on your PC. To prevent virtual USB devices from being  
configured limitlessly, use the unique driver installation procedure described below that  
enables your PC to identify terminals via single virtual USB device.  
Once this installation procedure is carried out for the PC, no more driver installation will be  
required for that PC to identify machines. If BHL2 Maintenance Driver is already installed to  
your PC, fully uninstall the BHL2 Maintenance Driver before installing Brother Maintenance  
USB Printer Driver.  
(1) Check that the power switch of the machine is turned off. Disconnect the USB cable  
that connects the machine with PC.  
(2) Turn on your PC.  
(3) Open the front cover, and turn the power supply of the machine on while holding down  
the SW supporter. Make sure that the Toner/Drum/Error LED lights up.  
(4) Release the SW supporter, and then make sure that all LEDs are off.  
(5) Press the SW supporter for the 2 seconds, and the Error LED lights up.  
(6) Click the “maintenance.exe” of the Printer Maintenance Driver which has been copied  
in the “hl2100” folder to start.

Drum Unit Life  
How to Read the Drum Unit Life  
- 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.  
How to calculate the drum unit life  
The drum unit life is based on the “drum counter” or the “number of drum rotations”.  
The drum counter is based on the total printed pages on the drum unit. This total  
printed pages should be reset every time you replace the drum unit with a new one.  
(Refer to "2.1 User Maintenance Mode" in Chapter 5.) Basically this amount is equal to  
the assured printable pages of the drum unit.  
If under the situation with a little print number of sheets per one job, the “page counter  
based on the number of drum rotation” exceeds the “drum counter” based on the total  
printed page.  
Refer to the calculation of the drum unit life based on the number of drum rotation  
below;  
How to calculate the page counter  
The number of drum rotations for the first page printed is about 15. The number of drum  
rotations per one page for the second or later page printed (continuous printing) is 4.3.  
Using these figures, the page counter is calculated as follows:  
Page counter based on the number of drum rotations = (Number of drum rotations for  
the first page printed + (Number of drum rotations per one page for the second or later  
page printed x (Number of pages in continuous printing - 1)) / 15  
(* The number of drum rotations per one page continuous printing.)  
Example: Starts to print when the machine is in the Ready state.  
Continuous printing Page counter based on the number of drum rotations (Pages)  
1 page/job  
(15 + (4.3 x (1 - 1))) / 15 = 1  
(15 + (4.3 x (2 - 1))) / 15 = 1.29  
(15 + (4.3 x (18 - 1))) / 15 = 5.87  
2 pages/job  
18 pages/job  
If you leave the machine without printing for a long time, the number of drum rotations is  
increasing. If you print one page per one job every time after leaving the machine  
without printing for a long time, the drum unit life is shorter than usual.

21) Developer Roller Counter Reset 2 (For the standard toner cartridge)  
22) Developer Roller Counter Reset 3 (For the high-capacity toner cartridge)  
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.

OTHER SERVICE FUNCTIONS  
2.1 User Maintenance Mode  
This section describes what the end user should do when replacing the consumable parts.  
■ Resetting the drum counter  
The printed image may deteriorate when using the drum unit to a certain degree. The  
machine detects how much the drum unit is used with the drum counter and lights up the  
Drum LED when the drum unit life is nearly at the end of its life to indicate to the end user that  
the drum unit life reaches the end of its life soon, in order to prevent the printed image defects  
due to drum unit deterioration.  
The machine does not provide the function which resets the drum counter automatically  
when the drum unit is replaced with a new one. If replacing the drum unit with a new one  
without resetting the drum counter, the counted value of the old drum unit is used  
continuously so that the Drum LED is not off.  
Fig. 5-5  
When replacing the drum unit with a new one, it is required to reset the drum counter  
following the steps below:  
<Procedure>  
(1) Open the front cover while the power supply of the machine is ON, after check the LED  
of the above-mentioned, and verify that the Error LED is lit.  
(2) Keep the SW supporter pressed down until all LEDs on the control panel light up.  
(approx. four seconds)  
(3) Release the SW supporter when all LEDs light up and take the old drum unit out of the  
machine.  
(4) Verify that Error LED is lit, and install a new drum unit into the machine.  
(5) Close the front cover.  
Note:  
When the machine printed out more than 100 pages after the drum counter is reset, the  
replace counter for the drum is updated.

■ Initializing the developing bias  
When replacing the toner cartridge with a new one, the new toner sensor detects that the  
toner cartridge is replaced, and the developing bias is initialized automatically. Therefore, the  
end user is not necessary to initialize the developing bias.  
If replacing the toner cartridge which contains enough toner with a used one, the new toner  
sensor cannot detect that the toner cartridge is replaced so that the developing bias is not  
initialized. In this case, the print density may be lighter than usual.  
In such a case, initialize the developing bias forcedly following the steps below:  
<Procedure>  
• Standard toner cartridge  
(1) Open the front cover.  
(2) Take the drum unit out of the machine.  
(3) Press the SW supporter.  
(4) Install the drum unit into the machine.  
(5) Press the SW supporter.  
(6) Close the front cover.  
• High-capacity toner cartridge  
(1) Open the front cover.  
(2) Take the drum unit out of the machine.  
(3) Press the SW supporter.  
(4) Install the drum unit into the machine.  
(5) Press the SW supporter twice.  
(6) Close the front cover.  
■ Wireless LAN setting (HL-2170W only)  
When the machine is in a standard state, you can switched to the Effective/Invalidity of the  
wireless LAN setting by pressing the [Go] button for 10 seconds. At the same time, switched  
to the Effective/Invalidity of the wired LAN setting. It is switched to a set value opposite to a  
current set value, whenever switching. and then the wireless network information (Net  
Config) printing is implement.  
Check that which of wireless LAN or wired LAN became effective. Judge by the Active or  
Inactive from “Node Type” which is mentioned in “Net Config” of “Printer Settings”.
