Unable to Clean 46
Unable to Init. 46
Unable to Print 46The 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 generic inks may 
cause frequent cleanings 
because generic inks 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-genuine 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).

Routine maintenanceB
Replacing the ink cartridgesB
Your machine is equipped with an ink dot 
counter. The ink dot counter automatically 
monitors the level of ink in each of the 
4 cartridges. When the machine detects an 
ink cartridge is running out of ink, the machine 
will tell you with a message on the LCD.
The LCD will tell you which ink cartridge is low 
or needs replacing. Be sure to follow the LCD 
prompts to replace the ink cartridges in the 
correct order.
Even though the machine tells you to replace 
an ink cartridge, there will be a small amount 
of ink left in the ink cartridge. It is necessary 
to keep some ink in the ink cartridge to 
prevent air from drying out and damaging the 
print head assembly.
IMPORTANT
Brother strongly recommends that you do 
not refill the ink cartridges provided with 
your machine. We also strongly 
recommend that you continue to use only 
Genuine Brother Brand replacement ink 
cartridges. Use or attempted use of 
potentially incompatible ink and/or 
cartridges in the Brother machine may 
cause damage to the machine and/or may 
result in unsatisfactory print quality. Our 
warranty coverage does not apply to any 
problem that is caused by the use of 
unauthorized third party ink and/or 
cartridges. To protect your investment and 
obtain premium performance from the 
Brother machine, we strongly recommend 
the use of Genuine Brother Supplies.
 
aOpen the ink cartridge cover.
If one or more ink cartridges have 
reached the end of their life, for example 
Black, the LCD shows 
B&W Print Only or Cannot Print .
bPress down to unlock the release lever 
and take out the ink cartridge for the 
color shown on the LCD.
 
 
cOpen the new ink cartridge bag for the 
color shown on the LCD, and then take 
out the ink cartridge.

dTurn the green knob on the protective 
yellow cap clockwise until it clicks to 
release the vacuum seal, then remove 
the cap (1).
 
 
eEach color has its own correct position. 
Insert the ink cartridge in the direction of 
the arrow on the label.
 
fGently push in the ink cartridge until it 
clicks, and then close the ink cartridge 
cover.
 
gThe machine will automatically reset the 
ink dot counter.
Note
• If you replaced an ink cartridge, the LCD may ask you to verify that it was a brand 
new one (for example,  Did You Change 
Black ). For each new cartridge you 
installed, press  Yes to automatically reset 
the ink dot counter for that color. If the ink 
cartridge you installed is not a brand new 
one, be sure to press  No.
• If the LCD shows  No Cartridge or 
Cannot Detect  after you install the ink 
cartridges, check that the ink cartridges 
are installed properly.
 
CAUTION 
If ink gets in your eyes, wash them out with 
water at once and call a doctor if you are 
concerned.

IMPORTANT
• DO NOT take out ink cartridges if you do not need to replace them. If you do so, it 
may reduce the ink quantity and the 
machine will not know the quantity of ink 
left in the cartridge.
• DO NOT touch the cartridge insertion  slots. If you do so, the ink may stain your 
skin.
• If ink gets on your skin or clothing  immediately wash it off with soap or 
detergent.
• If you mix the colors by installing an ink  cartridge in the wrong position, clean the 
print head several times after correcting 
the cartridge installation.
• Once you open an ink cartridge, install it in  the machine and use it up within six 
months of installation. Use unopened ink 
cartridges by the expiration date written on 
the cartridge package.
• DO NOT dismantle or tamper with the ink  cartridge, this can cause the ink to leak out 
of the cartridge.
 
Cleaning the outside of the 
machineB
Clean the Touchscreen as follows:
IMPORTANT
• Disconnect the power cord from the AC power outlet when you clean the 
Touchscreen.
• DO NOT use any type of liquid cleaners  (including ethanol).
 
aClean the Touchscreen with a dry 
lint-free soft cloth.
 
Clean the outside of the machine as 
follows:
IMPORTANT
• Use neutral detergents. Cleaning with volatile liquids such as thinner or benzine 
will damage the outside surface of the 
machine.
• DO NOT use cleaning materials that  contain ammonia.
• DO NOT use isopropyl alcohol to remove  dirt from the control panel. It may crack the 
panel.
