When i print a normal print the white background turns into a grey shade but the rest of the print is fine ie if i were to print an a5 picture on an a4 the picture will be fine but the rest of the page will be ashy grey
Inspect imaging drums for any signs of leakage or excess toner that could be falling onto the print as it travels though the printer. Any leaking imaging drums should be replaced.
Verify environmental conditions. See article Dealing with humidity, humidifiers. If the environmental conditions are not within the specified range, the printer should be moved before trying to troubleshoot the cause to the background toner.
Determine if any of the imaging drums were exposed to light for an extended period of time (more than 10 minutes). If so, then Replace the imaging drum. (Xerox is not responsible for any imaging drums that have been damaged by over exposure to light.)
Additional Recommendations: Background toner may increase, if printing occurs at temperatures towards the higher end of the specified operating temperature range. For this reason, it is recommended that the printer be moved to another area if at all possible.
In addition, very smooth media types such as glossy; allow toner to more easily scatter about the page prior to becoming fused. Try using a less smooth media if at all possible.

Grey shading likely due to either bad black cartridge. Try a different cartridge first thing. After that, print a PQ quality test page from the control panel to see if they defect shows on all pages. If it does then you may have a bad transfer belt.
Is the paper a shade of grey with no image? or is there an image with a grey background? If there is a image with a grey background you should try a new toner module. If that doesn't resolve the issue, clean the xerographic drum, make 10 blank copies, if the cleaning doesn't resolve the issue than install a new xerographic module.
Try printing a light stripes test page (Troubleshooting, print quality problems, troubleshooting print quality page).
If you do not appear to have many missing jets but the colours are all just wrong it may be that the ink has gone stale. Run a couple of head cleans and you should see the colours start to improve. If it is getting better, all you can do is keep running head cleans until you have replenished all the ink in the printhead well. This problem is common in situations where a lot of black and white printing is done, with very little colour. Alternatively, it could be that your wiper/cleaning blade is not cleaning the head properlyand is smearing the different coloured inks across the head, or possibly that yourprinthead is leaking colours but I think the first solution should solve your problem. Hope this helps.
If the amount of background toner shading becomes unacceptable, the procedures described below may help to clear the condition:
* Increase the density setting. This will decrease the amount of background shading. * Change the paper to a lighter basis weight. * Check the printer's environment' very dry (ow humidity) conditions can increase the amount of background shading. *Replace the toner cartridge. *Replace the transfer roller
I have looked and this problem confused me to no end.
I started searching through engineering notes from Xerox and found this line which I am copying and pasting.
This is not my opinion I can send you the entire report if you wish.
But sadly here is the answer.
Although supported, glossy paper will exhibit background toner and is a limitation of the printer technology.
