Re: print head for brother mfc420cn
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

Inkjet printers need to be used frequently to prevent ink drying out and blocking the print head nozzles. If the print head cleaning maintenance routine does not clear the blockages, then print head needs replacing, but it may be expensive. It may be more cost effective to buy a later model and better printer than replace the print head.

Usually the print head just needs to be cleaned. There's a Brother utility included with your printer, that you can select Clean. Run this. Afterwards run a print test page to see if it has cleared up your problem. If the unit STILL does it, your print cartridges may be low, or perhaps a 3rd party print cartridge was used, and the printer doesn't really KNOW how much ink is in them.
I believe the print cartidge itself, IS the print head, thereby, when you install a new cartridge, you renew the print head. which is good. However, I don't know on this model. If not, the print head, can be cleaned with a cotton q-tip with a little alcohol.
No, I suspect that this is Brother's proprietary code.
It is up to the manufacturer to continue with the development of code to support the newer operating systems. If Brother has announced a driver for printer then they should release code for any ancillary programs to allow the printer to work properly.
If Brother is telling you that they have no plans to fully support their product under Win 7 and the printer is fairly new then I would start with a corporate complaint letter.
