Brother MFC-440CN - print quality terrible, almost non-existent in spite of many cleaning operations.


It sounds like the printhead needs to be replaced. Brother may cover the cost of repair if you call them at 877-276-8437 and tell them the prints are "missing black ink". Very common problem that a new printhead should fix.

I'm not quite satisfied with color and black tone. What settings would you recommend.


You do not say what exact model of printer you are using so any answer will be generic rather than specific.

Poor colour and black tone can be as a result of various factors:
1. Poor paper quality that you are printing on.
2. Poor ink or toner quality being used.
3. Use of Ink / Toner saving modes or software.
4. Worn or damaged printer components such as the fuser roll on a laser printer and other similar consumables with a limited page use life.
5. Poor quality content being printed, i.e. low quality images being printed at too high a print resolution.

How to improve print quality 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 (see Brother numbers on page i).
Checking the print quality
If faded or streaked colors and text appears on your output, some of the nozzles may be clogged. You can check this by printing the Print Quality Check Sheet and looking at the nozzle check pattern.
1 Press Ink.
2 Press or to select Test Print.
Press Menu/Set.
3 Press or to select Print Quality.
Press Menu/Set.
4 Press Color Start.

6 Check the quality of the four color blocks on the sheet.
7 If all lines are clear and visible, press 1 (Yes), and go to Step 10.
OR

HP L7700 officejet printer leaves streaks on black ink lines only. Have cleaned heads repeatedly, changed black and color cartridges - nothing works.


Print in grayscale (black area streaking only) If the streaks are in a black area of a black and white printout, change to grayscale printing.
NOTE: This step does not apply to color printouts.
  1. In the application you are printing from, click File , and then click Print .
  2. Make sure the printer is selected and click Properties .
  3. Click the Color tab, and select Print Grayscale and High Quality .

We have recently bought a second hand OKI C5200 Colour Laser Printer and even though the black and white print seems to be great the clour is coming out with coloured streaks, what would you recommend?


One or more of the drums may be defective. Swap the black with another color and print a document. If that color printed the charectors ok, then continue the test with the other drums each taking a turn in the Black drum position until you find the bad drum.
