Phaser 6700 error code 309.003.03

[ChristopherO]

I have a xerox phaser 6700 that is giving me a laser failure error after a toner leaked inside the printer.  I removed the unit, checked all the connections, and found nothing physically wrong with it so I cleaned it up inside and out with some air duster, reinstalled it. I'm still getting the same error on startup. 

Is there anything else I should check or should I go ahead and order a new laser scanner unit?

If it helps at all the same unit has had the paper feed drive and imaging drum drive replaced for a engine sensor failure (unrelated)

Hi Christopher,

Thank you for using the Support Forum. The error you are getting is a laser failure.  If powering the machine off and back on after you cleaned it up did not clear the code then service would need to take a look at the machine.  Please consider contacting your support centre for further assistance.
