(13) An Optical disc cannot be ejected.
<Possible cause>
The Optical disc is being written to, the disc is bad, or there is an error in the DVD drive.
<Action>
1. Gently press the eject button a few times (at least five times).
2. Insert an eject pin into the manual emergency eject hole. (Refer to "2.6.1 Inserting an
Optical disc") When the disc tray opens slightly, hold and pull it out by hand.
< NOTE >
・The disc cannot be ejected because, after the processing to copy data has
finished, the end record is written to the Optical disc.
Wait several minutes until the drive access lamp turns off and the disc is
ejected.
・Press the eject button gently. Do not jolt the drive. Failure to heed this instruction
might result in data writing being forced to stop and ejection of the disc.
・Turn off the main power of the equipment before you eject an Optical disc by using
the eject hole. Do not insert an eject pin at an angle or apply too much force.
・An eject pin does not come with the equipment. If an eject pin is not available, use
instead a pin that fits the hole of the eject hole.
