Before we begin, I would like to make sure you understand that Just Answer is not affiliated with any service provider or manufacturer and we do not have control over their systems. Our ability to fix issues like this are therefore very limited and I ask that you take that into consideration before leaving a negative rating. Also keep in mind that some product-related problems are not "fixable" and the appropriate answer may include directing you to an authorized service center for your product. If you reached our site by mistake, or if I am not able to help you, you can request a refund at http://www.justanswer.com/refund or by e-mailing***@******.***
The message you are seeing is usually indicative of a problem with one of the tape sensors in the unit... meaning the sensor needs to be replaced. Unfortunately it's not typically something an end user can fix so the best course of action would be to bring the unit into a repair shop.
