GENERAL DESCRlPTlONl
I. FEATURES
1. Front loading and minimal machine space.
The copier is constructed so that paper is loaded into the cassettes and the deck from the’front,
enabling a compact design.
2. Super fine toner (single-component) for high resolution.
Development of images by the single-component projection method promises stable copy quality, and
super fine panicles give enhanced resolution.
3. Full range of basic features.
.The copies may be reduced /enlarged between 50% and 200% in the zoom mode: in addition, they
may be reduced / enlarged at four fixed reproduction ratios each.
.The copies may be as large as A3 / Ledger or as small as a postcard in size; further, a wide variety of
paper materials may be used including tracing paper and OHP.
.The copies may be either of four colors: i.e., red, blue, green, or brown. (NP3050 only)
Although compact in design, the copier has a duplexing unit, thanks to its set-back mechanism. (NP305g only)
. In addition to the above, the copier is equipped with mechanisms that enable automated copying work:
i.e., auto paper selection, auto reproduction, ratio selection, and auto exposure control (AE).
