How to improve print quality
Cleaning the print head
To ensure good print quality, the machine will regularly clean the 
print head. You can start the cleaning process manually if needed.
Clean the print head and ink cartridges if you get a horizontal line in 
the text or graphics on your printed pages. You can clean Black only 
or three colors at a time (Cyan/Yellow/Magenta), or all four colors at 
once.
Cleaning the print head consumes ink. Cleaning too often uses ink 
unnecessarily.
Caution
Do NOT touch the print head. Touching the print head may cause 
permanent damage and may void the print head’s warranty.
1Press  (Ink ).
2Press   or   to select  Cleaning.
Press 
Set.
3Press   or   to select  Black, Color  or All .
Press 
Set.
The machine will clean the print head. When cleaning is 
finished, the machine will go back to standby mode 
automatically.
If you clean the print head at least five times and the print has 
not improved, call Brother Customer Service (See  Brother 
numbers  on page i).

the cleaning and test print procedures at least five times. If ink is still 
missing after the fifth cleaning and test print, replace the ink cartridge 
for the clogged color. (Perhaps the ink cartridge was in your machine 
over six months or the expiration date written on the cartridge 
package has passed. Or, the ink may not have been stored properly 
before use.)
After replacing the ink cartridge, check it by printing another Print 
Quality Check Sheet. If the problem still exists, repeat the cleaning 
and test print procedures at least five times for the new ink cartridge. 
If ink is still missing, call Brother Customer Service (See  Brother 
numbers  on page i).
Caution
Do NOT touch the print head. Touching the print head may cause 
permanent damage and may void the print head’s warranty.
When a print head nozzle is 
clogged the printed sample 
looks like this. When the print head nozzle 
is cleaned, the horizontal 
lines are gone.

Packing and shippi ng the machine
Whenever you transport the machine, use the packing materials that 
came with your machine. If you do not pack the machine properly, 
you could void your warranty.
Caution
It is important to allow the machine to ‘park’ the print head after a 
print job. Listen carefully to the machine before disconnecting it from 
the power source to ensure that all mechanical noise has stopped. 
Not allowing the machine to complete this parking process may lead 
to print problems and possible damage to the print head.
1Lift the scanner cover from the right-hand side of the machine 
until it locks securely into the open position.
2Remove all the ink cartridges and attach the protective parts. 
(See Replacing the ink cartridges  on page 6-22.)
Caution
If you are not able to find the protective parts, do NOT remove the ink 
cartridges before shipping. It is essential that the machine be 
shipped with the protective parts or the ink cartridge in position. 
Shipping without them will cause damage to your machine and may 
void your warranty.
When attaching the protective parts, 
make sure they clip into place as shown in the diagram.
