1.9 Options

The optional Auto Document Feeder and optional Transparency Unit designed for use with the GT-7000 scanner may also be used with the EPSON Stylus Scan 2500 under the following restrictions.

1.9.1 Local Copy

ADF

If a document is loaded in the ADF tray, the Stylus Scan loads and scans that document.

If a document remains on the document glass, a copy is not produced normally.

Even if multiple copies are selected, the Stylus Scan ignores this setting and produces only one copy per document sheet.

TPU

The TPU cannot be used in Local Copy mode. The Stylus Scan ignores the TPU in this mode.

1.9.2 Scanning

ADF

Same as the GT-7000.

TPU

If the Stylus Scan receives transparency scanning commands, it will turn on the TPU lamp and scan the transparency after the warm-up period. The Stylus Scan ignores the ADF in this mode. After scanning, the TPU lamp remains on until the TPU is turned off or until the Stylus Scan receives reflective document scanning commands.

If the Stylus Scan receives reflective document scanning commands, it will scan the document normally.
