Maintenance Manual Paper Handling Overview
_______________________________________________________________________________________
2.1 Introduction
As described in chapter 1.1.1, this printer is designed to be extremely flexible in paper
handling.
Moreover, the new mechanism has been designed to be, first of all, ergonomic for a
better and easier end-user operation.
2.1.1 Paper Handling Architecture
All the paper paths described below can co-exist and can be selectable via MENU and
SW commands.
Paper Feed Options (Pull Tractor, Push Tractors) presence and type are detected at
Power-up.
The printer automatically switches from one path to the other except for the rear pull
tractor positions.
Via operator panel menu it is possible to select one macro per each path (up to 6) or a
single format (equal for all paths).
The basic configuration provides these ways to manage the paper formats:
(In the next figure the paths for continuous modules are indicated as <
⋅⋅⋅
>, while the
paths for single sheet forms are indicated as --->; each path is identified with a number).
•
SINGLE SHEET
A semi-automatic frontal single sheet insertion (PATH 1).
The cut sheets, envelopes or particular paper formats are manually loaded in this
path.
When a sheet is inserted, the sensors detect its presence and the printer
loads the paper automatically through the cut sheet stand without any other action.
•
CONTINUOUS MODULE (FANFOLD) WITH PUSH TRACTOR UNIT
Through a user installable/removable push tractor unit the fanfold module can be
fed through the following positions:
PUSH FRONT mode (PATH 2) with push tractor unit installed in the front position.
PUSH REAR mode (PATH 3) with tractor unit installed in the rear position.
The continuous module exits from the rear paper slot (PATH 5).
•
DOUBLE MODULE (FANFOLDS) WITH PUSH TRACTOR UNITs
Through a second optional user installable/removable push tractor unit the
following feeding position for continuous module is available for alternate use:
FRONT+REAR PUSH fanfolds mode.
The first fanfold from the front in push mode with basic push tractor unit installed
in the front position (PATH 2), the second from the rear in push mode with the
optional push tractor unit installed in the rear position (PATH 2).
For this path, the fanfolds exit (once at a time) from from the rear paper slot
(PATH 5).
