I. FEATURES
1. Copies as large as A3 in size (DIRECT) may be made, and the copyboard is of a
fixed type.
• Although compact in design, the copier enables making copies as large as A3 in size in the
DIRECT mode.
• The copyboard is of a fixed type so that pages of a book may be copied with much ease.
2. Zooming between 50% and 200%.
• Copies may be made in reproduction rations of between 50% and 200%, selectable in 1%
increments.
3. Front loading for faster supply of paper.
• Paper is loaded from the front of the copier so that the cassette* may be replenished with
paper without wasting time. The design also saves space.
*Universal and its capacity is 500 sheets.
4. Single-component fine particle toner for high resolution.
• Images are developed using the single component toner projection method. Further, the
copier uses toner of extremely fine particles for enhanced image quality.
5. Multifeeder (stack bypass) pick-up.
• As many as 50 copies (80 g/m2) may be made continuously using the multifeeding mecha-
nism.
6. Low warm-up time
• The copier warms up in than 25 sec.
