Print quality difficulties
DifficultiesSuggestions
Printed pages are curled.Low quality thin or thick paper or not printing on the recommended side of the 
paper could cause this problem. Try turning over the stack of paper in the 
paper tray.
Make sure that you choose the Paper Type that suits the print media type you 
are using. (See Acceptable paper and other print media on page 16.)
Printed  pages  are  smeared. The Paper Type setting may be incorrect for the type of print media you are using, 
or the print media may be too thick or have a rough surface. (See Acceptable 
paper and other print media on page 16 and Basic tab in the Software Users 
Guide.)
Printouts are too light.If this problem occurs when making copies or printing turn Toner Save mode 
to Off in the machine menu settings. (See Toner Save in Chapter 1 of the 
Advanced Users Guide)
Set Toner Save mode to Off in the Advanced tab in the printer driver. (See 
Advanced tab in the Software Users Guide.)
Network difficulties (For DCP-7065DN / HL-2280DW)
DifficultiesSuggestions
Cannot print over a wired Network. If you are having Network problems see the Network Users Guide for more 
information.
Make sure your machine is powered on, is on-line, and is in Ready mode. 
Print the Network Configuration list to see your current Network settings. (See 
Network Configuration List in Chapter 1 of the Advanced Users Guide.) 
Reconnect the LAN cable to the hub to verify that the cable and network 
connections are good. If possible, try connecting the machine to a different port 
on your hub using a different cable. You can check the current wired network 
status from the Network control panel menu.
The network scanning feature 
does not work.(Windows
®)
It is necessary to set the third-party Security/Firewall Software to allow Network 
scanning. To add port 54925 for Network scanning, enter the information below: 
In Name: Enter any description, for example Brother NetScan.
In Port number: Enter 54925.
In Protocol: UDP is selected.
Please refer to the instruction manual that came with your third-party 
Security/Firewall Software or contact the software manufacturer.
For more details, you can read FAQs and troubleshooting suggestions at 
http://solutions.brother.com/
.
(Macintosh)
The network scanning feature may be unable due to the firewall settings. 
Change or disable the firewall settings. If you are using a third-party personal 
Firewall software, see the Users Guide for your software or contact the 
software manufacturer.
Re-select your machine in the Device Selector application located in 
Macintosh HD/Library/Printers/Brother/Utilities/Device Selector or from

Other
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.

Improving the print qualityB
If you have a print quality problem, make a copy first (put a document on the scanner glass and 
press Start). 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
Using non-Brother supplies may affect the print quality, hardware performance, and machine 
reliability.
 
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 16.)
bCheck that the drum unit and toner cartridge assembly is 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 Setting for Replace Toner is set to 
Continue (Continue mode). 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 
Chapter 2 of the Software Users Guide.
Clean the corona wire of the drum unit. See Cleaning the corona 
wire on page 34.
Put in a new toner cartridge. See Replacing the toner cartridge 
on page 29.
Put in a new drum unit. See Replacing the drum unit on page 35.

Hollow printMake sure that you use paper that meets our specifications. See 
Acceptable paper and other print media on page 16.
Choose Thick Paper mode in the printer driver, choose Thick in 
the machine’s Paper Type menu setting or use thinner paper than

Page skewedMake sure that the paper or other print media is loaded properly 
in the paper tray and that the guides are not too tight or too loose 
against the paper stack.
Set the paper guides correctly. See Loading paper on page 8.
If you are using the manual feed slot, see Loading paper in the 
manual feed slot on page 10.
The paper tray may be too full. See Loading paper on page 8.
Check the paper type and quality. See Acceptable paper and 
other print media on page 16.
Check for loose objects such as torn paper inside the machine.
Verify that the two green envelope levers inside the back cover 
are set to the same position.
Verify that the two gray Anti-Curl Levers inside the back cover are 
set to the same position.
If the problem only occurs during duplex printing, check for torn 
paper in the duplex tray, verify that the duplex tray is inserted 
completely, and verify that the back cover is closed completely.
 
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 16.
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 
Users Guide.
 
Wrinkles or creasesMake sure that the paper is loaded properly. See Loading paper 
on page 8.
Check the paper type and quality. See Acceptable paper and 
other print media on page 16.
Turn over the stack of paper in the tray or try rotating the paper 
180 in the input tray.
