EPSON Stylus PHOTO 2100/2200 2.2.3.6 CD-R Printing Mechanism (Only for Stylus PHOTO 2100) ! 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.
