Cleaning the print headB
To maintain good print quality, the machine 
will automatically clean the print head when 
needed. You can start the cleaning process 
manually if there is a print quality problem.
Clean the print head and ink cartridges if you 
get a horizontal line or blank text in the text or 
graphics on your printed pages. You can 
clean Black only, three colours at a time 
(Cyan/Yellow/Magenta), or all four colours at 
once.
Cleaning the print head consumes ink. 
Cleaning too often uses ink unnecessarily.
IMPORTANT
DO NOT touch the print head. Touching 
the print head may cause permanent 
damage and may void the print heads 
warranty.

Note
If you clean the print head at least five 
times and the print has not improved, try 
installing a new Genuine Brother Original 
Innobella™ ink cartridge for each problem 
colour. Try cleaning the print head again 
up to five more times. If the print has not 
improved call your Brother dealer.

Packing and shipping 
the machine
B
When you transport the machine, use the 
packing materials that came with your 
machine. Follow the instructions below to 
properly pack your machine. Damage caused 
to your machine during transit is not covered 
by your warranty.
IMPORTANT
It is important to allow the machine to 
‘park’ the print head after a print job. Listen 
carefully to the machine before 
unplugging it to make sure that all 
mechanical noise has stopped. Not 
allowing the machine to finish this parking 
process may lead to print problems and 
possible damage to the print head.
 
aOpen the ink cartridge cover.
bPress the lock release lever to release 
the ink cartridge and take out all the ink 
cartridges. (See Replacing the ink 
cartridges  on page 70.)
cInstall the green protective part and then 
close the ink cartridge cover.
 
IMPORTANT
• Make sure that the plastic tabs on both 
sides of the green protective part (1) have 
securely clicked into place (2).
• If you are not able to find the green  protective part, DO NOT remove the ink 
cartridges before shipping. It is essential 
that the machine be shipped with either 
the green protective part or the ink 
cartridges in position. Shipping without 
them will cause damage to your machine 
and may void your warranty. When 
travelling with the ink cartridges still in the 
machine please keep the machine upright 
as this will protect the machine from 
leakage.
 
dUnplug the machine from the electrical 
socket.
eUsing both hands, use the plastic tabs 
on both sides of the machine to lift the 
scanner cover until it locks securely into 
the open position. Then unplug the 
interface cable from the machine, if it is 
connected.
