To set the machine in interrupt mode, press the INTERRUPT key (B41), which then starts to blink. When the
copying cycle is interrupted, the key remains on.
Lift the glass platen cover (taking care that any originals present in the automatic feeder do not fall out), remove
any document present and place the one you want to copy onto the glass platen.
Lower the cover, select the desired paper size and make copies in the ordinary way.
Having finished making copies, press the INTERRUPT key (B41) again to exit from interrupt mode. To resume
the interrupted copying cycle, press the START key (B38).
