DifficultiesSuggestions
The machine will not turn on. Adverse conditions on the power connection (such as lightning or a power surge) 
may have triggered the machine’s internal safety mechanisms. Turn the machine 
off and unplug the power cord. Wait for ten minutes, then plug in the power cord 
and turn the machine on.
If the problem is not solved, turn off the machine. Plug the power cord into a 
different known working outlet and turn on the machine.

Setting Dial Tone detectionB
When you send a fax automatically, by 
default your machine will wait for a fixed 
amount of time before it starts to dial the 
number. By changing the Dial Tone setting to 
Detection you can make your machine dial 
as soon as it detects a dial tone. This setting 
can save a small amount of time when 
sending a fax to many different numbers. If 
you change the setting and start having 
problems with dialling you should change 
back to the default No Detection setting.
aPress Menu, 0, 5.
bPress a or b to choose Detection or 
No Detection.
Press OK.
cPress Stop/Exit.
Telephone line interferenceB
If you are having difficulty sending or 
receiving a fax due to possible interference 
on the telephone line, we recommend that 
you adjust the Equalization for compatibility 
to reduce the modem speed for fax 
operations.
aPress Menu, 2, 0, 1.
bPress a or b to choose Basic(for 
VoIP)
, Normal or High (MFC-7470D, 
MFC-7860DW).
Basic(for VoIP) cuts the modem 
speed to 9600 bps and turns the 
error correction mode (ECM) off.
For a standard telephone line: If you 
regularly experience interference on 
your standard telephone line try this 
setting.
If you are using VoIP: VoIP service 
providers offer fax support using 
various standards. If you regularly 
experience fax transmission errors 
try this setting.

Normal sets the modem speed at 
14400 bps.

High sets the modem speed at 
33600 bps (MFC-7470D, 
MFC-7860DW).
Press OK.
cPress Stop/Exit.
Note
When you change the Compatibility to 
Basic(for VoIP), the ECM feature is 
only available for fax sending.

Improving the print qualityB
If you have a print quality problem, print a test page first (Menu, 4, 2, 3). If the printout looks good, 
the problem is probably not the machine. Check the interface cable connections or try printing a 
different document. If the printout or test page printed from the machine has a quality problem, 
check the following steps first. And then, if you still have a print quality problem, check the chart 
below and follow the recommendations.
Note
Brother does not recommend the use of cartridges other than genuine Brother Original 
cartridges or the refilling of used cartridges with toner from other sources.
 
aTo get the best print quality, we suggest using the recommended paper. Check that you use 
paper that meets our specifications. (See Acceptable paper and other print media 
on page 17.)
bCheck that the drum unit and toner cartridge are installed properly.
Examples of poor print qualityRecommendation
 
FaintTake out the drum unit and toner cartridge assembly. Hold the 
assembly level with both hands and gently shake it from side to 
side several times to spread the toner evenly inside the cartridge.
Check if the Toner Settings of Replace Toner is Continue 
(Continue mode) by pressing Menu, 1, 8. (See Toner settings in 
Chapter 1 of the Advanced Users Guide.)
Check the machine’s environment. Conditions such as humidity, 
high temperatures, and so on, may cause this print fault. (See the 
Safety and Legal booklet.)
If the whole page is too light, Toner Save mode may be on. Turn 
off Toner Save mode in the machine menu settings or Toner 
Save mode in the printer Properties of the driver. (See Toner 
save in Chapter 1 of the Advanced Users Guide or Advanced tab 
in the Software User’s Guide.)
Clean the corona wire of the drum unit. (See Cleaning the corona 
wire on page 67.)
Put in a new toner cartridge. (See Replacing the toner cartridge 
on page 56.)
Put in a new drum unit. (See Replacing the drum unit on page 61.)

Curled or wavyCheck the paper type and quality. High temperatures and high 
humidity will cause paper to curl. (See Acceptable paper and 
other print media on page 17.)
If you do not use the machine often, the paper may have been in 
the paper tray too long. Turn over the stack of paper in the paper 
tray. Also, fan the paper stack and then rotate the paper 180 in 
the paper tray.
Open the back cover (face-up output tray) for the machine to eject 
printed pages onto the face-up output tray.
Choose Reduce Paper Curl mode in the printer driver when you 
do not use our recommended paper. (See Other Print Options (for 
Windows
®) or Print Settings (For Macintosh) in the Software 
User’s Guide.)
 
Wrinkles or creasesMake sure that the paper is loaded properly. (See Loading paper 
on page 10.)
Check the paper type and quality. (See Acceptable paper and 
other print media on page 17.)
Turn over the stack of paper in the tray or try rotating the paper 
180 in the input tray.
