Sony DRS-1500a error 02-603

So I came into work this morning to find that my Sony DV deck has decided to be difficult today. It is giving me an error of 02-603 and tells me to eject the tape and inform service of the error. Upon trying to eject the tape it says the tape cannont be ejected. Any ideas of what the error is and how to get the tape out before I send it off for repairs (assuming I have to send it off).

Thanks in advance.
