the type of paper you are using. (See Media Type
 on page 1-8 in 
Software User’s Guide on the CD-ROM and Setting Paper Type on 
page 2-12.)
Make sure your ink cartridges are fresh. Cartridges remain fresh for up 
to two years if kept in their original packaging, after that the ink may 
become clogged. Cartridge expiration dates are printed on the package. 
Try using the recommended types of paper. (See About paper
 on page 
1-6.) 
The recommended environment for your DCP is between 20°C to 33°C.

Normal Printing mode to help avoid banding on some types of plain 
paper. In the printer driver Basic tab, click Settings, and check 
Enhanced Normal Printing.
If you continue to have horizontal bands, change the Media Type 
selection to Slow Drying Paper in the printer driver Basic tab to help 
enhance the print quality.

How to improve print quality
Cleaning the print head
To ensure good print quality, the DCP 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 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.
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 Management.
2Press   or   to select Cleaning.
Press 
Set.
3Press   or   to select Black, Color or All.
Press 
Set.
The DCP will clean the print head. When cleaning is finished, 
the DCP will go back to standby mode automatically.
If you clean the print head at least five times and the print has 
not improved, call your Brother dealer for service.

If you still see missing ink in this Print Quality Check Sheet, repeat 
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 colour. (Perhaps the ink cartridge was in your DCP 
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 your Brother dealer for service.
Caution
Do NOT touch the print head. Touching the print head may cause 
permanent damage and may void the print head’s warranty.
