Components

The major components of the InfoPrint 4100 Advanced Function Duplex Printing System are a pair of printers, hereafter referred to as a Duplex Printing System.

A Duplex Printing System can be used for simplex and duplex printing applications.

In this publication the first printer is called Printer 1, and the second printer is called Printer 2.

Printer 1

This printer includes:

Printer 2

This printer includes:

Complete duplex printing system

A Web Cooling System can be included with InfoPrint models MD1/2, HD3/4, HD5/6, TD1/2, and TD3/4 in Inline, 'H' and Left-Angle Configurations. Other duplex models include a Buffer/Flipper Unit. Each printer engine also includes an integrated urge unit.

Web Cooling System

Note:
The web cooling system must be installed by your Customer Support Specialist.

The web cooling system for the inline configuration consists of a Cooling Tower (1) a Vacuum Unit (2), and must be used with an attached Air Bearing Flipper (3).

The vacuum unit provides adjustable tension on the forms to control the web. The cooling tower cools the web before it enters the Air Bearing Flipper.

The web cooling system for the ‘L’ configuration consists of a Cooling Tower (1) a Vacuum Unit (2), an Air Supply Unit (3) and a Air Bearing Turnbar with 90° turn (4). The web cooling system for the ‘H’ configuration consists of the same devices, with the addition of two walkovers and an additional Air Bearing Turnbar with 90° turn.

The vacuum unit provides adjustable tension on the forms to control the web. The cooling tower cools the web before it enters the Air Bearing Turnbar. The air supply unit provides air for the cooling tower and air bearing turnbar(s).

Air Bearing Flipper and Tall Buffer/Flipper Unit

The Air Bearing Flipper Unit and the Tall Buffer/Flipper Unit guide the paper path from the first printer to the second printer in a dual-printer configuration without the web cooling system. They may or may not invert the paper, depending on configuration, and provide additional paper cooling.

The following figure shows both the Tall Buffer/Flipper Unit (1) , and the Air Bearing Flipper Unit (2).

Paper Paths and Feature Codes

Different devices allow forms to take the following paths from the first printer to the second printer:

The air bearing turn unit or tall buffer/flipper unit turns the forms over (flips) so the other side of the forms can be printed by the second printer. In the case of ‘L’ and ‘H’ configurations, turnbars are used to flip the paper at each 90° turn in the paper path. Because of the high speed with which forms travel through Printer 1, a "tall" Buffer/Flipper Unit is used to aid in cooling the paper before it enters Printer 2 in either the inline or left/right path configuration without the web cooling system. The inline configuration uses an Air Bearing/Flipper Unit.

Table 1 shows configurations, machine types, models and feature codes available, including the different buffer/flipper components that are provided for supported configurations in a duplex system.

Note:
Buffer/Flipper Units or the Web Cooling System are ordered with the MD1, HD3, HD5, TD1, and TD3 Model printers.
Note:
For 'H' Configurations only. A web drive source (or urge unit) may be required between printer Models MD1/2, HD3/4, HD5/6, TD1/2, and TD3/4 Web Cooling System, depending on the distance between engines.

Preprocessing/Postprocessing Interfaces

Preprocessing/post processing device interfaces allow additional input and output capabilities beyond the standard forms input source and output stacker in the system printers.

Preprocessing/post processing device interfaces allow output capabilities and additional input capabilities beyond the standard forms input source in the system printers.

Two preprocessing/postprocessing device interfaces (one in each printer) are provided. Additional interfaces can be purchased.
