 CD/DVD Tray Home Position Detection Sequence
The following sequence is performed after opening the Front Cover (CD-R
Sensor: closed), inserting the CD/DVD Tray to the specified position, and pressing
the Paper button.
When the close signal of the CD-R Sensor is detected, no paper is fed from the
ASF even if the Paper button is pressed. In this case, pressing the Paper button
executes a CD/DVD Tray home position detection sequence.
1. When the APG Assy is driven, the PG position is set to “++” and the Driven
Roller of the Upper Paper Guide presses onto the CD/DVD Tray.
2. When the Carriage Unit moves to the left and the PW Sensor detects the CD-
R, the Carriage Unit returns to its home position (HP).
3. After waiting for about 5 seconds at the HP, the Carriage Unit moves to the
CD/DVD Tray HP detectable position (right end of the CD/DVD Tray).
4. The CD/DVD Tray is pulled towards the ASF, the PW Sensor detects the CD/
DVD Tray HP, and then the Carriage Unit moves to the center of the CD/
DVD Tray.
5. When the PW Sensor detects the white marking in the center of the CD/DVD
Tray, the CD/DVD Tray is fed in the paper ejection direction.
6. The Carriage Unit moves to the left, the PW Sensor detects the white marking
on the left, then the Carriage Unit moves to the right, and the PW Sensor
detects the white marking on the right.
7. The Carriage Unit moves to the center of the CD/DVD Tray, and the PW
Sensor starts detection of the front and back direction of the CD-R. After the
front end of the CD-R is detected, the CD/DVD Tray is fed towards the paper
ejection direction, and the back end of the CD-R is detected. After that, the
CD/DVD Tray is fed to the center of the CD-R in the paper ejection direction.
8. The Carriage Unit moves to the left, and the PW Sensor starts detection in the
horizontal direction of the CD-R. After the left end of the CD-R is detected,
the Carriage Unit moves to the right, and the right end of the CD-R is
detected.
9. The Carriage Unit stops after moving to the CD/DVD Tray HP detectable
position, then the CD/DVD Tray is fed towards the ASF.
10. When the CD/DVD Tray stops operating, the Carriage Unit moves to the
carriage HP and stands by.
If the CD/DVD Tray HP, the white marking, or the CD-R cannot be detected within the
steps predetermined for the CD/DVD Tray HP detection sequence, the CD/DVD Tray
is ejected and Paper Out Error is displayed.
