HP3600N color fade

The magenta has run out (red).
Replace the HP 22 tri-color cartridge.
It probably has yellow and cyan (blue) left in it, and the black is most likely working as well, but if any of the 3 colors in the tricolor cartridge run out, the whole cartridge must be replaced.
For instance, if I printed my vacation photos and there was a lot of water and blue sky in all of them, the cyan might run out long before the cartridge life expectancy.
Also, don't forget that cartridges are rated in pages printed at 5% coverage.
Since a photo is about 25% of a full page, a photo printed at full bleed (edge to edge) will only yield 32 4 X 6 inch photos from a cartridge rated at 160 pages (5X expected coverage = 1/5 the prints)

Copied this from the specification on HP site.

It would appear not to take 5 x 7. It's the 7" is to small, 8.5 is the smallest.

t is easy to add a background picture by using the Watermark feature. First, you will click on “Page Layout”. In that menu bar (or ribbon), click on “Watermark”. A window menu will open. At the bottom of that window menu, click on “Custom Watermark”.
In the new menu that opens, check “Picture Watermark”, then “Select Picture” to find an image file on your computer to use. You have the option to have the picture look faded, as a watermark, or displayed in its full color. Check “Washout” for the faded option, or uncheck, to view the background picture in its full glory.
You will then need to choose the size of your background picture, by selecting one of the options under “Scale”.
To remove the watermark, simply click “Watermark”, and choose the “Remove Watermark” option.
Even if you don’t choose the “Washout” option, the background image will appear faded while you are working on your page. But, if you view the page through “Page Preview”, you can see how the background will look when printed.
To get to the "Page Preview" command, click on the Office Button on the upper left hand corner of the Word 2007 screen. Move your cursor over the "Print" option, and another menu will open to its right. On that menu, click "Print Preview".

I GOT A CLARIFICATION REQUEST AND I SENT FURTHER INFORMATION BUT AS OF YET I HAVE NOT RECIEVED ANY FURTHER INFORMATION BACK FROM "KEEPITSIMPLE".

No, it's an ink jet printer

The paper size must be set to borderless in both the application (MS Word) and the printer driver. To set borderless printing in the application, follow the steps below.

2. In the Print dialog box, click Properties , and then click the Paper/Quality tab.

I would suggest using a text box instead of a water mark and adjust the properties of the font color in the text box to be a very light color to your choosing then copy this and put it in the four places that you want. I think you can do this in works as well as word.

some printers share the ink from color to black but you can select if you wants to use only black just go to printer than properies than select to use only black but you probably have to remove the empty color one

Check your application's print settings (for e.g. MS Word). Then check the printer's properties and print settings. If nothing works you also try re-installing the latest printer driver. If you use MS word should check the page setup option, for paper size errrors. If the color of your margin is red and the red ink is out then you won't se the margin line.
