CHAPTER 5 TROUBLESHOOTING

5-9

  Print Quality

✒

Note

You can clear a print quality problem by replacing an ink cartridge with a

new one if the 

Ink

 LED (

(BC)

 LED or 

(MY) 

LED) is on or

blinking.

Question Recommendation
Printed pages contain white
horizontal lines or the image is
faint.

ABCDE

or Faint Images

• 

You may clear the problem by cleaning the print
head several times. (See “

Cleaning the print head”

in Chapter 4

).

• 

If the same problem occurs after cleaning, print the
test print to identify the cartridge that is causing the
problem and replace the ink cartridge. (See
“

Replacing the ink cartridges” section in Chapter 4

).

If the same problem still occurs, contact your dealer or
our authorized service representative.

Nothing is printed on the page.

• 

Clean the print head several times. (See “

Cleaning

the print head” section in Chapter 4

).

• 

Make sure that the ink cartridges are not empty. If
they are, replace the ink cartridges. (See “

Replacing

the ink cartridges” section in Chapter 4

).

• 

If the same problem occurs, contact your dealer or
our authorized service representative.

The colors of your print output
are not what you expected.

• 

Carry out print head cleaning.

• 

Try test printing from the maintenance program in
the printer driver.

• 

Check to see if the ink cartridges are installed
correctly and are not empty.

• 

You can adjust the color by using the custom setting
in the driver. Colors which printers can express and
colors you see on monitors are somewhat different.
The printer may not be able to express exactly some
colors on your monitor.

Check if the printer driver settings are correct.

Vertical lines are not aligned or
the outline of characters is
faint.

In Bi-Directional Printing, the printer prints from right
to left and left to right. Therefore, sometimes vertical
lines may not be aligned. Adjust the alignment through
the printer driver after carrying out a test print or select
uni-directional printing in the printer driver.

Envelopes are stained with ink. 

When the printer platen gets stained, clean the printer
platen referring to ‘

Cleaning the Printer’ section in

Chapter 4.

The printout is not clear or the
color is not vivid.

• 

Use Brother special papers or very white papers.

• 

Check to see that you are not printing on the reverse
side of special paper.

• 

Check if the ink cartridges are installed correctly.
