3 SETUP

Setup consists of a number of Menu’s that contain software settings.

It is important that the correct software settings are made in the DOC Menu so that
everyday Customer documents are handled correctly. Document dimensions
determine the DOC Menu software settings. Therefore, when a Customer receives a
new printer, or when a new document is introduced, this Menu’s settings should be
checked and modified as necessary.

The printer does not need to be connected to the Host Computer during Setup.

3.1 Introduction

A Software Setting consists of assigning a value to a parameter where:

• Parameters - are shown vertically under each Menu

• Values - are shown horizontally next to the Parameter.

Software Settings are held in a matrix where:

• Parameters (matrix vertical plane ) are reached using a Setup Function which

advances the document under the printhead

• Values (matrix horizontal plane ) are reached by using a Setup Function which

moves the Printhead along a line.

3.1.1 Setup Functions

These are:

Vertical Tab the document is advanced under the printhead to a new

line when the Button Bar is pressed down and released
after two seconds.

Horizontal Tab the printhead is moved a fixed horizontal distance along a

line when the Button Bar is held down for less than one
second (Hit).

Setup 3-1

3.1.2 Setup Controls

These are:

Button Bar providing three functional periods of operation:

• Press down and release in less than one second (Hit)

• Press down and release after two seconds

• Press down and hold down until the engine runs and the document moves,

then release

3.1.3 Menu’s and Parameters

On entering Setup, you are prompted to Select a Menu or Quit the Setup. Menu’s
are Selected or Quit from the start and end point, QUIT OR SELECT. Printer
Settings are printed from the VIEW point. Thus, the structure is :
