Hi  - Go ahead and try the steps in this document.  It will walk you through cleaning the contacts on both the cartridge and in the carriage.  What can happen over time is ink residue can accumulate on the contacts preventing the ink cartridges from working properly.  If this doesn't resolve the issue, try setting the cartridge with the nozzles face down on a damp paper towel for about 45 seconds just to resolve any problems with the ink nozzles.

 

Hope that helps.

In addition to the steps mentioned check the warranty dates on the cartridges as shown here.  If they are years past the warranty period it is possible the cartridges have failed, even if they were new in the box.  Also gently blot the printhead on a damp tissue to make sure that there are stripes of cyan, magenta and yellow color.  If there is not a strong color blot on the tissue the cartridges are probably the issue. 

 

The black-only test page confirms that the issue is in the printer or cartridges, not with the computer or drivers.

Thank you for your help. Although when tested by wiping on a lint free paper there was ink produced you were correct in suspecting the problem was the age of the replacement cartridge. I purchased a further new one and it has solved my problem! Once again THANKS!!!
