The print is blurred. It looks like it's printing over itself. We have cleaned it several times and replaced all print cartridges. It worked fine the last time we used it which was a year ago. We store it in our rental unit to use while we stay here for the summer months. This is a Brother MFC 420 CN. Whats up?

Paul,

did you had a paperjam the days before?

The encoder strip which gives the print head the position is out of position. It has to be fixed into the ph.

Read my post here (same issue and same procedure):

For the drivers and manual, you can go to brother's website. Here's the link for your specific printer:

http://welcome.solutions.brother.com/bsc/public/us/us/en/dlf/download_top.html?reg=us&c=us&lang=en&prod=mfc420cn_us

This should enable you to get up and running.

If you need something that is not in that group of downloads, you would need to contact Brother to order additional items.

You can cancel a fax job that is stored and waiting in the memory.
1 For MFC-210C,
press Menu/Set, 2, 5.
For MFC-420CN,
press Menu/Set, 2, 6.
Any jobs that are waiting will appear on the LCD.
2 If you have more than one job waiting, press ▲ or ▼ to select the
job you want to cancel.
Press Menu/Set.
—OR—
If you only have one job waiting, go to Step 3.
3 Press 1 to cancel.
To cancel another job go to Step 2.
—OR—
Press 2 to exit without canceling.
4 Press Stop/Exit.

That should do it for clearing faxes you dont need you can also print off all the faxes in the memory and I believe that clears it.
Enjoy,
Lee
