I. FEATURES
1. Front-loading.
• The copier is designed to accept cassettes from the front for ease of use (two cassettes holding
250 sheets each).
• The copier is given two cassette holders, thereby eliminating the need for cassette replace-
ment in making copies of different sizes.
• The copier’s multifeeder allows feeding multiple postcards.
2. Full line of automatic features.
• The copier has an auto paper selection mechanism as standard, which selects paper of the
correct size in response to placement of a document.
• With the auto reproduction ratio selection mechanism, the copier calculates the correct repro-
duction ratio according to the specified copy size.
• The AE (auto exposure) mechanism ensures crisp reproduction of newspapers and blue-print
documents.
• The copier’s auto-start feature lets you press the COPY START key during the wait period so
that the copier will start making copies as soon as it becomes ready.
3. HQ jumping toner.
• The copier uses Canon’s own HQ (high quality) jumping toner for reproduction of clear
characters and photos.
• The toner is a single-component type, which provides stable images.
• In addition, a 30mm-dia. high sensitivity OPC drum is used to enable enhanced image repro-
duction and a compact copier design.
4. Man-machine interface.
• As many as 20 copies (A4, landscape) may be made per minute.
• The zoom mechanism allows reduction down to 50% and enlargement up to 200% of the
original image.
• The page separation mode serves to speed up copying bound documents.
• The copier accepts documents as small as a postcard or as large as A3.
5. A variety of options to choose from for full automation.
The copier communicates with its options at a higher speed than ever, resulting in more output
per given time*.
*With options, up to 20 copies/min; 1:1 (A4, landscape).
• ADF-A1/ADF-D1 for automatic document feed.
• Sorter-A1 for automatic sorting and grouping (20 bins).
• MS-A1 for automatic sorting and grouping (10 bins).
• Control Card V (configured as built-in) for copy volume control (up to 200 groups).
• Stapler Sorter for stapling copies sorted in its ten bins.
• Paper Deck Pedestal-J1 for improved paper pick-up capacity.
