HP Designjet T520 Main PCA Board. It is verified to work without errors by me -- A HP Certified Technician trained to work on the HP DesignJet printers since 1995.THIS ITEM REQUIRES THE RETURN OF YOUR DEFECTIVE PART. I've had service calls on several T520 with similar error codes.
The last one was BA7E70E6. The'B' codes harkens back to the day when I routinely saw this type of error on the old 1050c\ 1055cm models. I used to tell customers you have the'error code of death'. In more technical terms, the Main PCA Board has a defective chip or routine call somewhere on it and needs to be replaced.The item "HP Designjet T520 Main PCA Board - ONE YEAR WARRANTY - CQ890-67097" is in sale since Tuesday, April 19, 2016.
