Cleaning the Print Head

Using the Head Cleaning utility
Using the control panel buttons

If you find that the printout is unexpectedly faint or some dots are missing, you may be able to solve these problems by cleaning the print head, which ensures that the nozzles are delivering ink properly.

You can clean the print head from your computer using the Head Cleaning utility in the printer software or from this product itself by using the control panel buttons.

Note:

• Print head cleaning uses both color and black inks. To avoid wasting ink, clean the print head only if the copy quality drops (for example, blurred printout, incorrect or missing color.)

• Use the nozzle check first to confirm that the print head needs to be cleaned. This saves ink.

• When the Error light is on and a message appears on the LCD panel to prompt you to replace the ink cartridge or to indicate the ink is low, you cannot clean the print head. In this case, replace the appropriate ink cartridge first.

Using the Head Cleaning utility

Refer to the appropriate section below to use the Head Cleaning utility.

For Windows

Follow the steps below to clean the print head using the Head Cleaning utility.

If the nozzle check page does not print satisfactorily, you may need to repeat the head cleaning and print the nozzle check pattern again. See Cleaning the Print Head.

Note:

• If the copy quality has not improved after repeating this procedure four or five times, turn this product off and leave it alone overnight. Then, perform the nozzle check again and repeat the head cleaning if necessary.

• If the copy quality still has not improved, one or both of your ink cartridges may be old or damaged and may need to be replaced. To replace an ink cartridge before it is empty, see Replacing an Ink Cartridge. If the copy quality remains a problem after replacing the ink cartridges, contact your dealer.

• To maintain good copy quality, we recommend copying a few pages at least once every month.

Have you carried out 2 or 3 head cleaning cycles? If not, do it. Is there ink on paper now after this cleaning? If so, but it is streaky, leave the printer for 24 hours and repeat the head cleaning. If not, you must soak the heads for at least 24 hours - use print head cleaning fluid or distilled water NOT TAP WATER. Proceed as follows:

Turn the printer on, and as soon as the print head starts to move, pull the power lead out of the printer, or turn it off at the mains. The print head should now be free to move by hand. Move it out of the way to the left. On the right you should see the print head parking area. There is a rubber cup that is designed to fit under the print head to keep the ink from drying out. Using a syringe or dropper, fill this cup with print head cleaning fluid. Then gently move the print head as far as it will go to the right. The print nozzles are now bathed in print head cleaner. Leave it for at least 24 hours, then repeat the cleaning cycle process.

Cleaning the print head
To ensure good print quality, the MFC 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.
1 Press Ink.
2 Press ▲ or ▼ to select Cleaning.
Press Menu/Set.
3 Press ▲ or ▼ to select Black, Color or All.
Press Menu/Set.
The MFC will clean the print head. When cleaning is finished,
the MFC 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

Hope that helps,

Take Care,

Michael
