The problem lies with the black toner cartridge. This is a common problem in these machines due to poor design by Brother. Best solution is to replace the offending color toner cartridge.

When I test print, I do not get a full pattern of black dashes. I changed ink cartridges and have the same result. The color test prints are fine


Hello,

If you are missing dots it is due to the print head not the cartridge.
Try doing a self cleaning a few times (max of 5) by pressing "ink" and select "cleaning"

If after 5 cleanings there's still a problem, you may need to have the printer serviced or replaced.
Since you're still getting most of your dots though, I think the cleanings should clear it out.

Thanks,

Pat

How do I set Brother 9440 MFC to print using black cartridge only?


Hello,

You can set the MFC-9440CN to print with the black toner cartridge only through the printer drivers.

If you are using Mac, this needs to be changed before you print or set a preset.

If you are using windows, follow the below steps.

1. Go to Start menu \ Control Panel \ Printers (devices and printers for windows 7)
2. Right click on the MFC-9440CN and select "printing preferences"
3. Under the "basic" tab, you will see "color mode"; simply select "mono"

Thank you,

MFC-9440 CN Laser Printer is producing vertical color line streak


Colored vertical streaks - looks like a transfer belt problem, and it's not user fixable. You may need a new belt unit - you can find it for around US$ 80-120, but you may want to have a technician inspect the unit first, since it could arguably be the drum instead, and you don't want to fork around US$ 100 and replace the wrong part.
You can try showing a printer sample at a print shop; by looking at the streaks it is possible to diagnose drum, fuser or belt problems.
Here you find a much more detailed page, for another printer model, but the issues are mainly the same for most color printers:

When I print I have black dots on it and a red


The drum probably needs to be cleaned. Refer to the Routine Maintenance section in Appendix C of your Users Guide.

Hp2600n printing black dots centre page


Could be a dirty fuser, try a laser printer cleaning sheet.

This is more of a problem if you use (some types of) remanufactured toner cartridges.

Magenta Dots vertically on Left margin of page


That is referred to as a repeating defect...most likely caused by a defect on the magenta drum unit. Here is a link for information on how to repair this problem:

BROTHER MFC-9440 CN all-in-one


hi, i fixed this problem but do have another however your solution might be to clean each cartridge using the user accesible sliders on each cartridge. they can be found by lifting each cartridge in succession and flipping the white cover up. on the left is a green knurled thumb thing. slide it back and forth 2-5 times and repeat for each cart.
good luck.
