Placing a Printable Disc
To print onto a printable disc, place it on the supplied multi-purpose tray, and then insert it into the printer.
Important
• Do not mount the multi-purpose tray until the message prompting you to load the printable disc
appears. Doing so can damage the printer.
• Remove any paper in the manual feed tray.
Note
• If test printing is executed onto test printing paper, depending on the paper type, the printer may not be
able to read its size correctly, preventing the border areas from being printed. Test printing paper
should be used for purposes of checking the envisioned layout.
1. Take out multi-purpose tray from multi-purpose tray storage compartment.
2. Open the paper output tray (A) gently.
3. When message prompting you to load printable disc appears, open the multi-purpose tray
guide (B).
