cartridge changing procedure. 
The printing speed slowed 
down during continuous 
printing. 
When printing is performed for an extended period of time, disc 
transfer and printing may be stopped temporarily. This is for slowing the 
printing speed to prevent overheating and damage to the product. 
Although printing can be continued when this occurs, it is 
recommended that you stop product operation and leave it with the 
power on for about 30 minutes. (The product will recover after about 3 
hours with the power off.)
Cannot publish discs.  See “When discs cannot be published” on page 161 in this guide.
