General

Chapter 1 General Information

1.1 Overview

This section describes the product and its intrinsecal main characteristics..

1.2 Scope of the Product

The product is intended to satisfy most of the counter applications in a ergonomic environment.
It is designed for versatile and reliable paper handling.

A specialized flat-bed mechanism allows paper to be fed without bending: in this way special documents, such as
multiple invoices, postcards, labels, tickets can be trouble-free printed.

1.3 Main Features

The following points put in evidence the main features of this product.

• Printing on a wide range of paper media: different types of cut sheets, multi-parts and passbooks.

• High print pressure for multi-parts documents

• High print quality supplied by a 24 wire print head

• High reliability paper handling

The straight paper path allows the printing on particular documents such as envelopes, multipart forms and
passbooks.

• Automatic paper thickness adjustment
The print head detects automatically the paper thickness for correct printing on any type of document. This printer
can print also on documents with a variable thickness, such as passbooks.

• Easy paper handling
The operator places the paper on the front table and the printer loads it without any other user intervention. The
paper ejection towards the front or the rear of the printer allows an easy access to the printed document.

• Automatic document alignment feature
The printer checks automatically the alignment of the top margin and the left margin of the document and adjusts
it, if necessary. The printout is therefore performed correctly independently from the paper loading position.

• Storage of two complete configurations for instant recall

• Standard parallel and serial interface and automatic switch-over function. The financial interface is available for

the IBM 4722 and the IBM 9068 protocols.

• Optional LAN 10/100BaseT or USB interface.

• Easy printer setup through an optically managed menu.

• Emulations: Epson 570, IBM Proprinter XL24E, XL24E AGM, IBM 2390+, 4722, 9068 and Olivetti PR40+, PR2,

1.5 Product Structure

1.5.1 Mechanism and Electromechanical Devices

The basic mechanism has been designed to support a flat-bed path oriented to an high reliability of the paper
handling.

Paper Handling

A stepper motor, supporting 1/180" paper step together with a minipitch belt, provides the movement to the paper
alignment and pressing front and rear rollers.

Rollers opening and Aligner selection

A stepper motor drives a guide installed in the left side of the printer that allows to open/close the paper pressing
rollers and to activate the Aligner mechanism (special rollers + stop bar) to provide the Auto Document Alignment or
Skew Adjustment feature.

Carriage Movement

A stepper motor provides the movement of a carriage, carrying the print head, which is driven by a stepper motor and
a minipitch belt.

Ribbon movement

The motion of the ribbon is driven by mechanical coupling and plastic gears assy that translate the bidirectional
movenent of the carriage to one way movement for the the pivot driving the ribbon. The ribbon drive assy is installed on
the left side of the vertical frame, near the pulley of the carriage motor.

Gap Distance

A special wheel installed on the body of the print head and a flexiible platen realize together the function of Automatic
Adjustment of the printhead gap according to the paper thickness in real time. The AGA wheel forcing continuosly on
the platen with a force depending from the thickness of the media interposed between them.

Sensors

There are 5 sensors in this printer for the following features:
Cut Sheet Loading (on the sensor board)
Cut Sheet Skewing (on the sensor board)
Paper Edge Detection (on the print head assy)
Home Position Detection (on the mechanical assy)

3.3.2 Printer Configuration

The steps necessary to configure the printer are the following:

1) Printing of the Setup forms

2) Filling in of the printed forms.

3) Reading of the filled in modules to store the parameters in NVM.

REMARK:
If the printed forms are available also in photocopies (not reduced), only the step 3 is necessary to configure
the printer.
After every reading phase it is possible to select the print phase to immediately see the new setup.

The default configuration of this printer matches most of the commonly used environments, but it may be necessary
to change some printer parameters. With this printer you print the forms for the setup, you fill them in, and then you
insert them back into the printer for reading.

Once the printer read the form, the new values are set.
The following is the complete description of the Setup Procedure.
To enter the Printer Setup Mode press and hold the ON LINE key pressed for at least 1 second while powering the

printer on. The printer enters the Setup Mode.

3.3.2.1 Print of the Setup Forms

1. Insert a blank sheet in A4 or Letter format.

2. The printer loads the sheet and stops.

3. The STATION1, ON LINE and STATION2 leds are unlit.

If the LQ key is pressed immediately after the printer enters in Setup Mode, all printer setup modules are
printed.

Pressing the ON LINE key:

• the printer prints the Self-test Page. In this way it is possible to check the current printer parameters.

• once the self-test is finished, the printer remains in Setup Mode.

Pressing the STATION1 key:

• the STATION1, ON LINE and STATION2 leds change and you can select the Setup Page you want to print as

follows:

Note: If more than one value is set for a parameter, the printer ignores these parameters and maintains the currently
set value.

Do not fill in the marker beside the title of the preprinted form, otherwise the printer will not be able to read that page.

3.3.2.3 Reading the Preprinted Forms

When the Printer Setup Forms have been filled in, insert them back into the printer. The printer is able to recognize
the Setup Forms by means of the markers on these pages. The printer reads the values marked for the various
parameters and configures the printer accordingly.

3.5.4 How to download to SP40 an existing configuration file

A configuration file, generated with the SP40 setup tool as previously described, can be simply used to duplicate the
same configuration on more printers.

SP40 unit has to be powered on in normal mode, connected to the PC through any active interface (Centronics or
Serial port).

Type: copy wnvm.dmp lpt1: /b command from a DOS shell,
where wnvm.dmp is the configuration file name.
The printer receives the file, checks for valid configuration format and in such a case the received content is recorded

into the non volatile memory.
After that the printer restarts the execution and downloaded configuration becomes the active.

Warning :

Configuration files generated by SP40setup tool are allowed to be used only on printers having te same firmware
version of the unit used to generate the file!
In any other case the received file is discarded by the printer without any change on NVM!

Chapter 4 Service Maintenance

4.1 Overview

This chapter describes how to maintain the printer in order to always obtain the best performances from it.
In this chapter it is possible to find also some helps to test printer and to identify defective components using
Test & Diagnostic facilities.

First-Level maintenance is based at O.R.U. (Optimum Replaceable Unit).

4.2 Initial Inspection and Tools

When the printer presents a trouble, before proceeding to the service maintenance, an initial inspection must
be done. In fact, a problem in the printout often is due to a bad or wrong condition of the printer itself.

The parameters that must be previous checked are: set-up, cleaning, paper specification.
After that, if the problem remains, a troubleshooting session can be activated.

Requested Tools

• A Multimeter for resistance and voltage measurements.

• Soft Cloth

4.3 Set-Up

Check for the following items to make sure they are full-filled.

• Is the printer placed in a correct position ?

• Is the environmental temperature in the nominal range ?

• Is the relative humidity in the nominal range ?

• Is the unit installed in a bad location ?

(Close to high temperatures or humidity, near heat sources, dusty areas, areas where gas is generated,
exposed to direct sunlight)

• Has the printer a good configuration ?

Please refer to the user manual or chapter 1 and 3 of this manual for more details on all these items.

4.4 Cleaning

No preventive maintenance, on a schedule basis, is required.
Periodic cleaning will help to keep your printer in top condition.
Clean the printer as follows:

• Every time that a maintenance operation has to be done or the ribbon cartridge has to be removed and

replaced by a new one, clean the lateral sides of the platen removing the paper dust. Use for this a soft
cloth or a little brush. This operation will be helpful for a correct behaviour of the edge sensor.

• Use a neutral detergent or water solution on a soft cloth to clean dirt and grease from the cabinet of the

printer.

• Do not use an abrasive cloth, alcohol, paint thinner or similar agents because they may cause

discoloration and scratching.

• Be especially careful not do damage the electronic and mechanical components.

Check for the paper paths condition and to make sure they are correct.
If they are dirty (by paper residues or by ink), please clean them using a soft cloth.

4.5 Lubrication

The following point of the mechanical assy should be lubricated when a maintenance activities is done in the
printers to avoid any seize in the movement of the parts.

• DO NOT LUBRICATE the main shaft, but only clean dirt.

Only a drop of oil can be put on the felts inside the carriage if they are dry. Before oiled the felts check
for their clean conditions. If it needs clean or replace them.
NOTE: the oil must be FOMBLIN YN06 (Ausimont, Montedison).

• Lubricate with Molykote PG30L silicon grease (Dow Corning Corporation) the following parts:

1) The surface of the selector cam (item 28 of figure 2.18) in contact with the associated lever.

2) Lateral side of the support of the platen assy (item 17 of figure 2.22) in contact with left and right metal
frame (item 18 of figure 2.22).

4.6 Paper Specifications

Also the paper is important to have high performances.
Check for the correct paper specifications.

See chapter 6 for more details.

4.7 Consumables

Compuprint recommends to use only its original consumables with original packaging.
In this way, a proper use of the printer at the quality level and reliability stated in the product characteristics
can be assured.

All usage problems typically related to not certified consumables can be avoided, such as:
an overall degradation of the printing quality level and often, the reduction of the total life of the product due to
the fact that the proper working conditions of the print head and other parts are not assured.

Moreover, the original consumables are controlled in compliance with the international standard rules
concerning:

• no cancerous materials

• no inflammability of the plastic materials

• other standard

Starting from the software release 1.7x, two important parameters for the service has been added and are printed on
the Self Test printout.

Ribbon Life counter
Print Head Life counter

The first item is under User responsability.
The User can reset it in three ways:

1 An item has been added in the Configuration Setup (Ribbon Replaced=no*, yes) in order to reset the ribbon life

counter (see chapter 3.3.2.4).

2 On html Printer Status Page this counter can be displayed and resetted under permission remotely (see

chapter 3.4).

3 It can be resetted also in T&D, when launching the T&D13 (conters reset), see chapter 5 for details.
The second item is under Service responsability.

5.1 Overview

For the field maintenance of this printer, a specific Test & Diagnostic feature has been developed.
This feature is built -in the basic firmware of the printer.
The version of the T&D is reported in the T&D printout together with the version of the basic FW and (if
present) the optional LAN FW.

The T&D may be executed with the standard Operator Panel of the printer or with a specific maintenance
Operator Panel with a 16 digits LCD display to take more easy and immediate the reading of the messages.
See chapter 2.2 to remove the standard o.p. assy and install the maintenance one.

The echo of the messages is also available on the serial interface, therefore it is possible to connect the
printer with a P.C. as a remote panel to read the message.
See chapter 5.11 later in this chapter how to use it.

5.2 How to run T&D USER (with standard operator panel)

Power on with ON LINE + STATION 1 keys starts the USER T&D procedure.

ON LINE + STATION 1

Push again

STATION 1

within 3 seconds to choose the STEP BY STEP mode.
If no action is done after 3 seconds or STATION 2 is pressed, the COMPLETE T&D (VERIFY mode) will be run.

5.3 GENERAL RULES FOR T&D OPERATIONS

The display is not present on the standard Operator Panel, therefore the message are done by specifi
combinations of the leds.

l = OFF status
¡ = ON status

£ = low frequency flashing status
¥ = high frequency flashing status

During T&D execution in Step by Step, the keys have the following meaning:

STATION 1 Decrement test number
STATION 2 Increment test number
ON LINE Execute test

After the execution of the selected test a submenu comes activated, so the meaning of the keys becomes:

STATION 1 Repeat test
STATION 2 Skip test (and return to the previous menu)
