8.1.5 Index Paper Attachment

The machine allows the use of index paper as a transfer medium. Start user mode, and select index sheet
mode and fit an Index Paper Attachment-A1 so that an index sheet may be inserted between sheets (index
sheet insert mode) or print in the index area (index production mode).
Index sheets are fed from the source of index sheets (cassette 3/4) selected from the control panel. (For
details, see the User Guide.)
