! CD-R tray home position detection sequence
When the CD-R attachment is fitted, the Release lever setting position (PG sensor:
Close, Release sensor: Open) and CD-R tray sensor (Close) are detected. By pushing
the CD-R tray into the specified position and pressing the Paper feed switch in this
status, the following operation is performed.
1. The Carriage unit moves to the CD-R tray home position detection position (white
label position).
2. The CD-R tray is pulled in the ASF direction.
3. When the PW sensor of the Carriage unit detects the CD-R home position, the
Carriage unit moves to the CD-R tray center position (horizontal center of the
CD).
4. The CD-R tray is fed in the paper ejection direction and the trailing edge of the
CD-R is detected. Then, the CD-R tray is fed in the ASF direction again and the
leading edge of the CD-R is detected. After that, the CD-R tray is fed to the CD-R
tray center position in the paper ejection direction.
5. In the position in Step 4, the Carriage unit moves rightward and the detection of
the CD-R horizontal direction starts. After the left end of the CD-R is detected, the
Carriage unit moves rightward again and the CD-R horizontal direction is
detected.
6. The Carriage unit stops at the CD-R tray home position detection position (paper
feeding direction) and the CD-R tray is fed in the paper ejection direction. When
the home position is detected, both the Carriage unit and CD-R tray stop operating
and are put in a standby status.
If the CD-R tray home position or CD-R cannot be detected in the specified step
operation of each step in the above sequence, the CD-R tray is ejected and Paper out
error is displayed. If the Release lever setting position (PG sensor: Close, Release
sensor: Open) and CD-R tray sensor (Close) are detected when the CD-R attachment is
fitted, pressing the Paper feed switch will not start paper feed from the ASF. In this
case, pressing the Paper feed switch performs the CD-R tray home position detection
sequence.
When the CD-R tray is detected, Release lever error is displayed if the Release lever
setting position is other than the CD-R position.
