2.2.3.2 CD/DVD Tray Base Lock Mechanism
To prevent the Printhead from being damaged by mistake, the printer is designed to
lock the CD/DVD Tray Base when the Carriage Unit is out of its home position.
The following explains the lock mechanism of the CD/DVD Tray Base.
 Lock Release Sequence
1. When the Carriage Unit returns to its home position, the Pump Motor drive is
transmitted to the Paper EJ Lock Release Cam.
2. The salient of the Cam presses down the Paper EJ Transmission Lock Lever
to release the tab of the Paper EJ Lock Lever from the Paper EJ Transmission
Lock Lever.
3. The CD-R Release Lever comes free from the Paper EJ Lock Lever and
comes down to enable the CD/DVD Tray Base to open.
When the Carriage Unit is out of its home position, the salient of the Paper EJ Lock
Release Cam does not press down the Paper EJ Transmission Lock Lever, and the tab
of the Paper EJ Lock Lever is not released. Therefore, the CD/DVD Tray Base cannot
be opened.
