HP 5550 color Laserjet

[wdsmith]

I have an issue with the HP 5550 it is printing Grey background. I have talked with Tech support about this, and they have had me replace all of the following:

Toners all colors one at a time
Power supply
DC Controller
Transfer unit

But it still has a grey background.

Can anyone help me with this.

Does the "Grey background" cover the entire page... is the "background" a repeating image of previously printed text/images?

What about the fuser assembly? Has that been replaced?

Other possibilities:
1. Does this greying occur when you print a configuration page directly from the printer's control panel, or only when printing a document from your computer? Possibility of a corrupted/incorrect driver.

2. Upgrade the firmware.
