PIXMA IP8720 Driver and apps won't recognize L tray

[reelybored]

My Macbook Air M1 with Sequoia 15.2 paired with a Canon PIXMA IP8720 printer - for some reason Canon-Photo-Editor does not detect the L tray. I tried another CD/DVD labeler software and had no luck with it either. I updated all drivers and still nothing. What am I doing wrong? I can't figure it out and it is driving me mad.

Hi reelybored,

When placing a printable disc on the disc tray, do not touch the printing surface of the disc or the reflectors on the disc tray.  The reflectors are in "C" below:

Also, when inserting the tray, please make sure that the arrows are almost aligned and that the tray is not inserted too far:
