LED writing is superior to LD writing in unit-downsizing, noise reduction, and energy saving.

Four LED heads are installed on the inner cover and each PCDU is set in a specified location automatically when the inner cover closes. There is no distinction between the LED heads for black and for the other colors.

The writing process uses only the LED head, but the focus distance adjustment is performed by the LED head contacting the LED spacer which is on the drum.

  • All LED heads use the same parts, so you can swap them with one another for troubleshooting purposes.
  • The LED spacer contacts the drum, so the drum wears out gradually as it rotates. If a worn PCDU (out of lifetime) is used, its focus gradually becomes blurred.
