Black lines in display and printer will not turn off with on/off button

Printer display shows black lines across it and will not turn off with on/of button. What is our problem? Is there something seriously wrong with printer or is it something we can fix at home. We have tried disconnecting both the power source and USB cable and nothing seems to work.

The printer


You may need to clean the printhead: (make sure you have paper in the tray)

1) Press <Menu>

2) Press <Up> or <Down> arrow to select "Ink" then press <OK>

3) Press <Up> or <Down> arrow to select "Test print" then press <OK>

4) Press <Up> or <Down> arrow to select "Print quality" then press <OK>

5) Press the <Color Start> button. The quality test sheet will be printed. Check this printout for gaps in any of the colors or black in the pattern across the page.

6) The display on the printer will ask if the print quality is OK:

- If all lines are clear and visible, select "Yes"

- If gaps appear in the pattern, select "No"

7) If you select "No" the display asks (in turn) if the print quality is OK for black, and the three colors.

Respond "Yes" or "No" accordingly. (In this manner you may clean just the black or color nozzle that is giving you the problem)

8) The display asks if you want to start cleaning - choose "Yes"

9) After cleaning is finished press the <Color Start> button - the print quality sheet will print again.

At this point you may determine that another cleaning cycle is necessary. You may need to repeat cleanings (up to five times) to resolve the problem. Any more than that indicates a problem that may need brother customer support.

10) When the print quality test sheet meets with your approval, you may exit by pressing <Stop/Exit>

Carrier stall


The encoder strip is most likely the problem. Unplug the power from the printer. Open the front cover and move the cartridge carrier to the center. You should see a white ribbon cable, a thin plastic strip and a black belt with teeth.

The thin plastic strip is the encoder strip. It rides in a sensor on the back of the cartridge carrier that you will not be able to see. Reach in with the first finger of either hand and carefully strum the strip as if playing a guitar.

The strip will need to be lowered slightly and brought towards you slightly. Please be careful not to break the strip or your printer will not function. Once you believe the strip is set correctly, plug the power back and try printing the self test.

To self-test the printer, please follow the steps given below:

1. Press the "Menu" button 10 times. It should then read "Maintenance" on the printer's display screen.
2. Press the "Select" button once. You should then see "Cartridges" displayed on the printer screen.
3. Press the "Right Arrow" button 3 times, which then brings you to the "Self-Test" option.
4. Press the "Select" button once. It should print out a sheet of paper with horizontal color and black lines and smaller vertical lines.

The self-test should at least print out a set of either black or color bars, if not both (if you have a printer with both color and black installed simultaneously). Should this test fail, try it again without cartridges installed. If the self-test still fails to take paper in and make sounds like the carrier is moving across the paper, this is a hardware issue, and the printer will require service. If the self-test completes without any cartridges installed, run the self-test again with the color cartridge installed. (If you have both black and color cartridges, after this test, run the test again with just the black cartridge installed.) If you find that either cartridge causes the self-test to fail, please let us know.

If the self-test prints, but has lines or smudges or other print quality issues, please let us know. This includes any print quality issues and we need to know if the problems you have with your black or color are based in the printer, or communications with your computer, or the computer's software.  
If the self-test prints your test bar(s) clearly, the printer hardware is not at fault.

Not showing up on my computer


It seems there is a possibility of a problem with the printer itself, or perhaps the cartridges. You should first self-test the printer. Since we are unsure where the problem exists, we must do eliminative troubleshooting to rule out parts of the printing system. The self-test allows us to rule out software and the cable by testing the hardware by itself. Please note that this is not a "fix," but rather a diagnostic test to determine if your hardware is at fault.

Next, try this printer self-test by following the steps given below:

1. Please turn OFF the printer.
2. Press and hold the "Color copy" button.
3. Now, turn ON the printer.
4. Once you see "0" on the display, release the "Color copy" button.
5. Press the Up arrow button until "2"appears on the display.
6. Press the "Black copy" button to start the self test. Once the page has printed, the printer will stop printing.

The self-test should at least print out a set of either black or color bars, if not both (if you have a printer with both color and black installed simultaneously). Should this test fail, try it again without cartridges installed. If the self-test still fails to take paper in and make sounds like the carrier is moving across the paper, this is a hardware issue, and the printer will require service. If the self-test completes without any cartridges installed, run the self-test again with the color cartridge installed by itself. (If you have both black and color cartridges, after this test, run the test again with just the black cartridge installed.) If you find that either cartridge causes the self-test to fail, please let us know.


If the self-test prints, but has lines or smudges or other print quality issues, let us know. This includes any print quality issues, we need to know if the problems you have with your black or color are based in the printer, or communications with your computer, or the computer's software.

If the self-test prints your test bar(s) clearly, the printer hardware is not at fault. The issue may be a communication problem, or perhaps a software conflict.

However let me know the name and version of the operating system (Windows XP / 2K / NT, Windows Vista, Mac) that you are using on your computer. This information is important for me to troubleshoot the issue further.

Print cartridge missing


Please remove the cartridges from the printer. Take a dry lint free paper towel and gently wipe the contacts on the back of the cartridge (not the bottom from where ink is present). Wipe the contacts inside the printer (on cartridge carrier). Please snap the cartridges back into the cartridge carrier.

Next, try this printer self-test by following the steps given below:

1. Please turn OFF the printer.
2. Press and hold the "Color copy" button.
3. Now, turn ON the printer.
4. Once you see "0" on the display, release the "Color copy" button.
5. Press the Up arrow button until "2"appears on the display.
6. Press the "Black copy" button to start the self test. Once the page has printed, the printer will stop printing.

The self-test should at least print out a set of either black or color bars, if not both (if you have a printer with both color and black installed simultaneously). Should this test fail, try it again without cartridges installed. If the self-test still fails to take paper in and make sounds like the carrier is moving across the paper, this is a hardware issue, and the printer will require service. If the self-test completes without any cartridges installed, run the self-test again with the color cartridge installed by itself. (If you have both black and color cartridges, after this test, run the test again with just the black cartridge installed.) If you find that either cartridge causes the self-test to fail, please let me know.


If the self-test prints, but has lines or smudges or other print quality issues, let us know. This includes any print quality issues, we need to know if the problems you have with your black or color are based in the printer, or communications with your computer, or the computer's software.
