I have an issue. I don't think I an going to get any help or further support though from HP. I have had many communications with them and one is still open now but I hold little hope. There was clearly a built in hardware issue with a large batch of sprockets but HP are so far not willing to address this and replace them. I find it somewhat sad when a company of this size does not acknowledge a clear manufacturing defect and have an in house plan and budget to right their wrong without causing customer dissatisfaction.
