Stackless ADU
The Stackless Automatic Duplexing Unit (ADU) that is now employed in the e-STUDIO550/650/810
can reverse paper without stacking it, and It is structurally less complex than previous ADUs. As a
result of this mechanical rationalization and simplicity, there are fewer problems such as paper jams in
the case of duplex copying. Even in the unlikely event that a paper jam does occur, trouble-shooting is
now much easier and the user can have the machine back online in a few moments. In particular as
only one sheet is ever in the duplex unit at any one time.
New Sheet-Through Type RADF
In comparison with previous models, the e-STUDIO550/650/810 comes with a totally redesigned and
improved standard Reversing Automatic Document Feeder (RADF).
The new RADF is designed as a sheet-through type model, which has the new internal sensing and
paper transport mechanisms. It has not only improved two sided scanning speed, but has also
improved transport deviation and skew, thereby increasing the accuracy of every copy. A maximum of
100 sheets of paper (from LD to ST, A3 to A5) can be stacked on the RADF at a time and it can handle
2
paper between 13-34lbs, 50-127g/m in weight. Therefore, the new sheet-through type RADF provides
significantly more accurate handling of large print jobs of two-sided originals, making it ideal for
professional users like the POD market.
Post Fuser Inserter
The e-STUDIO550/650/810 can be equipped with a newly developed optional Inserter. This Inserter
provides an extra degree of functionality since it makes it possible to automatically—and accurately—insert
separately made covers and color photos at the proper places in a printout. In this regard it is worth
mentioning that the possibility of surface damage to color prints has been eliminated, because the inserted
paper is not transported through the system's internal mechanism and therefore is not affected by the heat
from the fuser unit.
The Inserter is certainly a blessing for booklet making and the production of promotional materials. 15
sheets of paper can be inserted per set, and the Inserter accepts up to 100 sheets of paper. The range of
paper types that can be handled includes normal paper, color-coated paper, thick paper up to 140lbs or
2
256g/m stock, and OHP sheets.
For even greater flexibility the Inserter incorporates its own fully independent control panel. This enables the
unit to be used "off-Line" to staple, hole punch and even saddle stitch documents previously produced on
other systems in the office environment.
