Hello,I am the person that will be helping you today.
What are you referring to when you mention the "disk guide"?
I will be standing by, looking forward to your response.
I am not familiar with that tray.
For this reason, I am opting out of the question and allowing another expert the chance to help.
The next expert will see all that is on this page, so there will be no need to repeat anything.
When another expert picks this up, you will be notified by email.
Thank you for your patience.
I am attaching an image that shows how to line up the disc guide tray with the triangular marks. Please take a look at it
When you try to push it in, are you trying to store the tray or actually use the disc guide tray?
