Note CAUTION Original-set indicator (ADF) The original-set indicator turns on when an original is placed on the document tray, and flashes when an original jams. 1 If the original is A3 or 11-by-17 inch in feeding length, open the original sub tray. 2 Set the side guide to suit the size of the original. The side guide lock must be removed if the width of the original is larger than 297 mm (A4/A3). For details, see "To remove the side guide lock" on page 382. 3 Place the originals with the first page on top. 4 As needed, set the appropriate copying mode on the copy module. 5 Press the copy module's Copy Start key. Warnings and actions If the original-set indicator flashes while an original is being fed, suspect a jam and perform the following: 1 Remove the originals from the document tray. 2 Open the upper cover, and remove the jam. Then, open the ADF to reset the warning. (If any original is on the copyboard glass, remove it.) If the jam is in the copy module, the copy module will run jam recovery mode and will automatically set the originals. Do not open the ADF to reset. 3 Set the originals in correct order, and set the stack in the ADF. 58 Chapter 3 - Operational overview EN
