Cause
There is no multi-purpose tray.
What to Do
Place a multi-purpose tray compatible media (discs or nail stickers) on the multi-purpose tray, and then attach the multi-purpose tray to the printer.
Then press the printer's OK button to cancel the error.
When you print on multi-purpose tray compatible media, use the supplied multi-purpose tray (the one with the "A" mark).
To cancel printing, press the printer's Stop button.
