Won't print just colour...

If that lines are consistent with the red and blue and it does not appear during black and white print that means the cleaning blade in the affected color units need to be replaced

Main Cartridge is black it is required for printing it is not possible to print black with other cartridge.

You have to refill both.

You're just going to have to keep printing until you see which cartridge is getting dry. It'll be either the black one or the colour one. This way you won't buy the wrong cartridge. If you print black text and it starts to come out grey then it's the black cartridge that needs to be replaced. The same with colour, if the picture looks faded then you'll need a new colour cartridge.

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.

when the color cartridge has to make black, it uses all three colors. printing blue indicates that the color cart. is getting low on red and yellow. get a new black cart. and a new color, 'cause it' s coming due.

Let me know

I would just set the text color to red or blue in your document.

Depending on the program that you use it could have different steps.

Here is steps in Word:

You can change the Colour of your text by highlighting the text and then clicking on the 'A' symbol on the toolbar. This will change your text to the Colour which is underneath the symbol 'A' on the toolbar. To change the Colour, click on the arrow next to the symbol and select one of the colours from the small box which appears. This will change the Colour of your text as soon as you click on the Colour.

Another way of changing the Colour of your text is to go to 'Format' and then click on 'Font'. The font window should appear. Select a Colour from the 'Colour' section. You can see a preview of what the text will look like in the box below. You can also add various effects to your text by using the options in the 'Effects' section. This will also allow you to see a preview in the box at the bottom of the window.

Hope this helps. Please remember to rate this information.

Secondly, go to Notepad and try printing somthing from that.

Have you tried a new colour cartridge? This is a classic sign that the cartridge may be low on ink. When printing text, assuming you are printing black, it is likely that the black cart is doing most of the work so the gaps are insignificant. You could try printing text in several different colours. If the colour cartridge is low, you'll find that some colours may be ok but others may have gaps.

Best to try a new cart if you have one.
