Typing white text on black background

Are the ink cartridges installed in the correct colour order?
Have you printed a test page through the printer's own control panel? What was the result?
Open a new document, using the default settings. Key in some test text. Try printing. What is printed?

Perform the head cleaner mantenace menu and feed roller cleaner then make a test print.

download any wallpaper that you like to the phone memory card and go to fil manager and select the memory card path and locate the downloaded image, and click the options where you will see the option set as wallpaper, done : )

stop using yellow paper, problem solved

Inkjet printer inks are dye-based, and that's the reason.

Perhaps this will help explain things. You know those little boxes of food colouring you can buy in the supermarket - the ones that have four little bottles of colour - red, blue, yellow and green. Within reason you can combine these to turn white icing into most colours. Use nothing and the icing is still white or use everything and the icing will go a black-brown colour. Use a couple of drops of red and blue and you'll get purple.

But if you start with black icing, there's nothing you can add that will make it anything but black.

It's the same with your inkjet printer - because white is obtained by not having any ink print on the white paper. But of course that only works when the paper is white. Naturally you'll get different results on all colours of paper, decreasing as the paper gets darker in colour. Print blue on yellow paper and you should get green printing.

The only way to print in white is to do what commercial printers do - use opaque inks and include a white ink in the process. And as far as I know there's no commercial ink that will do that with an inkjet printer.

I can hear lots of you muttering "Rubbish. Of course you can print light colours on dark paper." Well all I can say is, have fun experimenting, but you won't be able to do it.

About the only way to achieve the sort of result you may be after is to print the job then trim it and paste it in place. For instance, if you want to print onto a black or dark-coloured T-shirt then print onto white transfer material, trim the print to size and iron it in place.

Go to control panel select printers and then select lexmark left click and open printing preferences select graphics tab and uncheck the negative box, the printing will be normal from now on.

It's never going to be perfect (unless the background is quite light in colour), because the copier basically "sees" the coloured background as "gray", and the darker the background the more "gray" it looks. Try setting the original type to "photo" mode, and then adjusting the exposure a little lighter/darker....that's all you can basically do.

This may sound a bit dumb, but believe me as a tech support specialist, I have seen it happen. If you are trying to print a document, what color do you have set for text? I had a lady who wanted the text to be white on blue on the screen in Word and instead of setting it with a blue background and "auto" text, she set the text as white. White print on a white background (paper) doesn't show up...:-)

I can't imagine where toner could possible go from one of these sort of cartridges except on to your paper, I had a customer once with the same request and I found on their letter head that they printed with it had a single band of yellow across it hence excess yellow use,,,,,, Do your print runs of anything contain dark bands/underlines? I guess check to see if white background in any prints has a blueish tinge to it, or possiblly somehow black is running out and it is printing the blacks by mixing the colours (Check black block and text to see if it is really black not heaps dark blue to ensure black toner is operating)

next I'd be questioning if cartridges where brother ones?

Make sure the drums are properly seated in their cradels, and if posible, avoid designing with white small text in heavy solid areas that are made up of process colours. For reverse type in a black background, use spot color black rather than rich black. Other than than printing on a not as heavy card, that is about all you can do.
