It might just be my old manual, but I couldn't find that specific error code. In that manual the A07 error code relates to print paper, not master material.
Could you please confirm the error code? And sorry if my old manual lead me astray.
Also, if you haven't tried resetting the machine you should try that too. The easy way to do that is to hold down the "Reset" key and then turn the machine on, then continuing to hold the key down for a little while. Maybe five or so seconds. That is useful if the local power utility has suffered some irregularities which could cause voltage surges (energetic storms, nearby construction that disturbs the power lines and the like).

Ya A07-xxx is feed problem, enter or exit is even listed. Take a can of air and blow out the paper IN sensor as well as the exit section where the exit sensor is at. They can build up a layer of paper lint
