Chapter 1 Introduction
1. Features
This machine has following features.
High capacity ADF with high-speed scanning:
The DP120F/DP125F scans one Letter (A4) size document page in 1, 2 seconds (line density
8 dots/mm x 3.85 lines/mm) and stores it into memory. A maximum of up to 50 letter (A4) sheets
may be placed into the ADF at one time.
High-speed transmission:
The DP120F/DP125F uses a V.34 modem designed for 33,600 bps communications.
Multi-access:
Using the multi-access facility, multiple processes can be performed in parallel. Functions,
such as transmission reservation during reception, copying during memory transmission/re-
ception, etc. Maximizing the DP120F/DP125F’s high-speed scanning and multi-access capa-
bilities provides maximum office productivity and efficiency. Patterns of the multi-access are as
follows:
(1) Scan to Memory during Memory Transmission
(2) Scan to Memory during Reception
(3) Scan to Memory during Substitute Reception
(4) Copying during Memory Transmission
(5) Reception during Copying
(6) Reception during Memory printing
(7) Reception during List printing
(8) Scan to Memory during Memory printing
(9) Scan to Memory during List printing
Laser recording on plain paper:
Recording is performed on fixed sizes of paper - Letter, Legal, A4 - using a laser beam printer.
Halftone system:
Photographic images are clearly recorded by the 256 grayscales using the error diffusion method.
High resolution mode:
The DP120F/DP125F can transmit in ultra-fine mode (406 x 391).
G3 dual-line simultaneous communications:
By installing a 2nd NCU PBA (DP120F: option, DP125F: standard), the unit works as two fax
units. Accordingly, two-line simultaneous communications are realized.
