1 Introduction
This Matrix Printer has been developed for daily correspondence purposes in the
office. It meets the highest possible technical standards, and with proper use, it
should provide many years of trouble-free operation.
High-performance print qualities as well as operation with fanfold paper and cut
sheets can be chosen.
The following print qualities are available:
Copy Draft Print Qualitiy (DPQ Copy)
Draft Print Quality (DPQ)
Near Letter Quality (NLQ)
Letter Quality (LQ)
The electronic part controlled by a microcomputer operates the needle print head,
menu programming, and interface.
All elements of the printer control are arranged on printed circuit boards so that only
a few additional components are required such as
step motor for selection of paperpath or for automatic gap adjustment
DC-motor for carriage transport
step motor for paper feed
The following features and options will further enhance the printer’s capabilities:
pull tractor 1 (front) (standard)
manual single sheet feeder (front) (standard)
automatic sheet feeder rear (SFR) (option)
automatic sheet feeder front (SFF) (option)
pull tractor 2 (front) (option)
pull tractor 3 (rear) (option)
We recommend the use of original accessores for our printers. The use of others
than original parts may reduce the performance of the printer and cause defects on
the printer. For errors caused by the use of others than original accessories, your
warranty become invalid.
Caution: Activities described herein must only be performed by specially trained
and qualified service personnel! Harmful voltages can be touched.
