Greetings,
I see that you currently have a service call opened for this, but I wanted to reply for the benefit of anyone who might see this message in the future.
The mail alert you received was generated by the machine and was just an alert to the fault code of 00,020.68. If you were to receive this fault, many times it will clear on it's own after the machine is power cycled, however if it doesn't the machine will require a service visit.
Luckily, it should be a pretty easy fix by the technician, most likely it is just a faulty media path motor.
