Your problem is not fully explained above as to which color you are having difficulty with, however, the explanation below will more then likely apply to your issue as well. Simply substitute "yellow" for the color you are having an issue with. This is the explanation I gave to another user who was having problems with "yellow prints lite".


If you let the yellow ( or any other color ) toner get to the point where the toner cartridge was totally empty, there is one thing you can try which may help. From the "menu", select "maintenance", then go to "clean developer" and choose the ( which ever color ran low ). The machine will then churn for a few minutes. What happens is there is a tube that moves the toner from the toner cartridge down to the developer unit ( which is behind the imaging drum). If the toner was allowed to totally run out, there is an area of the tube which may have little or no toner in it. Each time you print, there is a spring auger within the tube that draws the toner to the developer. By running the "clean Developer" it turns the auger and re primes the tube.

If this does not fix the issue, and you have replaced the imaging unit, then the (insert color ) developer is defective and would need to be replaced.

This involves quite a bit of work and is not considered user replaceable.

SOURCE: dell color laserjet 5110 cn will not print color documents

This has to do with the document printing properties. When you are ready to print a document, choose properties and make sure you go through the printer settings under that software.
The test page only verifies the cartridges. The printer properties of the software control the printer during printing.
