Giacomos,

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.

Hope this help.

You can try this.
Press the access button, You will see a button called Enablement Code, then enter this number. *33886714351 .
Make sure you entter the * first, that is the button bottom left on the keypad.
That should allow you 5000 more pages. But it can only be done once. May or may not work on that product. But thats all I know.
