Error and Maintenance messagesB
As with any sophisticated office product, errors may occur and consumable items may need to be 
replaced. If this happens, your machine identifies the problem and shows a message. The most 
common error and maintenance messages are shown below.
You can correct most errors and clear routine maintenance messages by yourself. If you need 
more help, the Brother Solutions Center offers the latest FAQs and troubleshooting tips.

B&W Print Only
Replace Ink One or more of the color ink cartridges 
have reached the end of their life.
You can use the machine in 
black & white mode for approximately 
four weeks depending on the number 
of pages you print.
While this message appears on the 
LCD, each operation works in the 
following way:
 Printing
If you click Grayscale  in the 
Advanced  tab of the printer driver 
you can use the machine as a 
black & white printer.
 Copying
If the paper type is set to 
Plain Paper  you can make 
copies in black & white.
Duplex copy is not available when 
this message appears.
 Faxing
If the paper type is set to 
Plain Paper  or 
Inkjet Paper , the machine will 
receive and print the faxes in 
black & white.
If a sending machine has a color 
fax, the machine’s “handshake” 
will ask that the fax be sent as 
black & white. 
If the paper type is set to 
Other Glossy , Brother BP71  or 
Brother BP61  the machine will stop 
all print operations.  Replace the ink cartridges. (See 
Replacing the ink cartridges
 
on page 65.)
If you unplug the machine or take out 
the ink cartridge, you cannot use the 
machine until you change to a new ink 
cartridge.

Cannot DetectYou installed a new ink cartridge too 
quickly and the machine did not detect 
it. Take out the new ink cartridge and 
re-install it slowly until it clicks.
If you are not using Genuine Brother 
Innobella™ ink the machine may not 
detect the ink cartridge. Use a new Genuine Brother 
Innobella™ Ink Cartridge. If the error 
is not cleared, call Brother Customer 
Service.
An ink cartridge is not installed 
properly. Take out the new ink cartridge and 
re
-install it slowly until it clicks. (See 
Replacing the ink cartridges  
on page 65.)
Cannot Print
Replace Ink One or more of the ink cartridges have 
reached the end of their life. The 
machine will stop all print operations. 
While memory is available, black and 
white faxes will be stored in the 
memory. If a sending machine has a 
color fax, the machines “handshake” 
will ask that the fax be sent as black & 
white. If the sending machine has the 
ability to convert it, the color fax will be 
stored in the memory as a black & 
white fax. Replace the ink cartridges. (See 
Replacing the ink cartridges
 
on page 65.)
Comm.Error Poor telephone line quality caused a 
communication error. Send the fax again or connect the 
machine to another telephone line. If 
the problem continues, call the 
telephone company and ask them to 
check your telephone line.
Connection Fail You tried to poll a fax machine that is 
not in Polled Waiting mode. Check the other fax machines polling 
setup.
Cover is Open. The scanner cover is not completely 
closed. Lift the scanner cover and then close it 
again.
The ADF cover is not completely 
closed. Open the ADF cover and then close it 
again.
The ink cartridge cover is not 
completely closed. Firmly close the ink cartridge cover 
until it clicks.
Data Remaining Print data is left in the machines 
memory. Press 
Stop/Exit . The machine will 
cancel the job and clear it from the 
memory. Try to print again.
Disconnected The other person or other persons fax 
machine stopped the call. Try to send or receive again. 
If calls are stopped repeatedly and you  
are using a VoIP (Voice over IP) 
system, try changing the Compatibility 
to Basic (for VoIP). (See 
Telephone 
line interference / VoIP  on page 98.)
Document Jam/too LongThe document was not inserted or fed 
properly, or the document scanned 
from the ADF was too long. (See 
Using the ADF  on page 28.)

DR Mode in Use The machine is set to Distinctive Ring 
mode. You cannot change the 
Receive Mode from Manual to another 
mode. Set Distinctive Ring to 
Off. (See 
Turning off Distinctive Ring  
on page 44.)
High Temperature The print head is too warm. Allow the machine to cool down.
Hub is Unusable. A Hub or USB Flash memory drive 
with Hub has been connected to the 
USB direct interface. A Hub or USB Flash memory drive 
with Hub are not supported. Unplug 
the device from the USB direct 
interface.
Image Too Long. The proportions of your photo are 
irregular so effects could not be 
added. Choose a regularly proportioned 
image.
Image Too Small. The size of your photo is too small to 
trim. Choose a larger image.
Ink Absorber Full The ink absorber box or flushing box is 
full. These components are periodic 
maintenance items that may require 
replacement after a period of time to 
ensure optimum performance from 
your Brother machine. The need to 
replace these items and the time 
period before replacement is 
dependent on the number of purges 
and flushes required to clean the ink 
system. These boxes acquire 
amounts of ink during the different 
purging and flushing operations. The 
number of times a machine purges 
and flushes for cleaning varies 
depending on different situations. For 
example, frequently powering the 
machine on and off will cause 
numerous cleaning cycles since the 
machine automatically cleans upon 
power up. The use of non-Brother ink 
may cause frequent cleanings 
because non-Brother ink could cause 
poor print quality which is resolved by 
cleaning. The more cleaning the 
machine requires the faster these 
boxes will fill up.
Note
Repairs resulting from the use of 
non-Brother supplies may not be 
covered under the stated product 
warranty.
 
The ink absorber box or flushing box 
will need to be replaced. Contact 
Brother Customer Service or a Brother 
Authorized Service Center to have 
your machine serviced. (See  Brother 
numbers  on page i.) 
Other reasons for cleaning are:
1 Machine automatically cleans after  clearing a printer jam.
2 Machine automatically cleans after  sitting idle for more than 45 days 
(infrequent use).

Ink low One or more of the ink cartridges are 
near the end of their life. If one of the 
color ink cartridges is near the end of 
its life and a sending machine has a 
color fax to send, your machine’s 
“handshake” will ask that the fax be 
sent as black & white. If the sending 
machine has the ability to convert it, 
the color fax will be printed at your 
machine as a black & white fax. Order a new ink cartridge. You can 
continue printing until the LCD shows 
Cannot Print
. (See Ordering 
accessories and supplies  on page ii 
and  Replacing the ink cartridges  
on page 65.)
Low Temperature The print head is too cold. Allow the machine to warm up.
Media Error The memory card is either corrupted, 
improperly formatted, or there is a 
problem with the memory card. Put the card firmly into the slot again to 
make sure it is in the correct position. 
If the error remains, check the media 
drive (slot) of the machine by putting in 
another memory card that you know is 
working.
Media is Full. The memory card or USB Flash 
memory drive you are using has no 
available space or already contains 
999 files. Your machine can only save to your 
memory card or USB Flash memory 
drive if it contains less than 999 files. 
Delete unused files to free some 
space and try again.
No Caller ID There is no incoming call history. You 
did not receive calls or you have not 
subscribed to the Caller ID service 
from your telephone company. If you want to use the Caller ID feature 
call your telephone company. (See 
Caller ID
 in chapter 5  of the Advanced 
User’s Guide .)

memory drive in the media drive does 
not contain a .JPG file. Put the correct memory card or USB 
Flash memory drive into the slot again.
