Canon Printer not printing on CD/DVD

[DaDa]

I am using an iMac and A Canon MP810 Printer, which has been working fine. Just recently the CD Printer function does not work the tray with the CD or DVD moves into the printer ok when the print button is pressed, however the tray comes out again without printing the disk. I am using CD Label Print a program by Canon. I did work before but now it has decided not to. Can you help?

What has changed since it worked last?

As far as I know nothing has been changed, apart from the normal updates, I have downloaded Canon Drivers to try and fix it but they have not worked either.

The prompt that comes up after the disk Tray comes out of the printer again is as follows: Error No 1001 CD-R Tray is not inserted or a Printable Disk is not placed on the CD-R Tray. Load a printable disk on the CD-R Tray, insert the Tray along the Guide Rail, and then press the OK Button on the Printer. Printing will restart.

But of course printing does not start and the tray comes out again.
