1.1 FEATURES OF THE NP-70 COPIER
The NP-70 electrostatic copier is a completely new type copying machine which has been develop-
ed by Canon technology. This development places the NP-70 in a new category -the "Liquid,
Plain-paper-type Electrostatic Copier".
Due to the adaptation of the liquid development method for use with PPC-type copying, integra-
tion for the first time anywhere of the following features outstanding for conventional dry electro-
static copiers has been achieved.
1)
LARGE COPY SIZE OBTAINABLE
Obtainable copy sizes are from 7-1/8" x 10-1/8" to 11-5/8" x 16-1/2" (JIS BS to A3). Plain
paper copying above size 10-1/8" x 14-5/6" (JIS B4) is realized in the NP-70 for the first
time ever.
NOTE:
The size mentioned are approximate inch equivalents of Japan Industrial Standard
(JIS) sizes. Refer to the specification section for exact dimensions.
2)
HIGH COPYING SPEED
Approximately 15 half-size sheets (A4 or BS) can be copied in one minute.
3)
DESK-TOP COMPACTNESS
The NP-70 copier is designed highly compact so that the least amount of space is required.
As a result, large copier performance is obtained from small copier size.
4)
AUTOMATIC TONER REPLENISHMENT (ATR) EQUIPPED
ATR maintains a constant density of toner in the dispersant, resulting in copying uniformity.
5)
BUILD-IN SAFETY FEATURES
In the event that something abnormal happens during machine operation (ie: a paper jam),
operations are automatically stopped.
6)
CASSETTE-TYPE PAPER FEEDING
Use of different paper sizes is easy and quick due to the cassette-type paper holder. Addition-
ally, any troubles which might be caused by cassette mis-feeding are prevented by build-in
safety circuitry.
