The memory block, divided into the following three sections, is an integral part of the motherboard:

• EPROM (256 Kbytes), this memory contains the system firmware, the default

settings of the software parameters and the messages in the various languages

• STATIC RAM (8 kbytes), this memory contains:

- the current user and service software parameters

- the calibration settings (alignment settings)

- the telephone number list (one-touch dialling numbers and speed code dialling numbers)

- the power failure report with the memory erasure report if needed.

• DYNAMIC RAM (512 kbytes), this memory contains:

- the compression and decompression buffer

- the scanning buffer

- the print buffer

- the transaction memory (activity reports)

- the user memory (documents to send, documents received in the memory).

The data is retained in the dynamic memory even during a power failure by a backup

battery capable of powering the system for 72 hours. The facsimile machine must be left powered for 24 hours to recharge this battery.

The data is retained in the static memory by the 5-year duration system battery.

2.3.5 Printer Unit

The facsimile machine has a bubble ink jet system which uses a special head and

prints on plain paper.

The bubble ink jet print head consists of an interchangeable cartridge, which contains a sponge soaked with liquid ink, which is ejected from 50 nozzles made of a nickel and gold component, under the control of the signals that reach an electrical circuit consisting of 50 resistors (Fig. 2-13).

cartridge

nozzles

circuit

sponge

Each nozzle generates a drop of ink when the corresponding resistor is powered (+24 Volt) for a few microseconds.

The resistor is heated and the ink that is in direct contact with it evaporates, expanding like a bubble and pressing the rest of the ink against the nozzle.

602E52970 2-17

As a result, a drop of ink is ejected from the nozzle at a speed of 15 metres a second until it strikes the paper on which it makes a dot.

When the resistor is powered off, the bubble collapses quickly, drawing from the sponge a quantity of ink equal to the amount ejected. 800 microseconds after the ink has been ejected, the nozzle is ready to eject another drop.

• two series of symmetrical cams C1 and C2, integral with the shaft, which:

- through the upper profile PS move the ADF (or ASF) away from the RS rollers

- through the lower profile PI at the same time allow the ASF (or ADF) to come

in contact with the RS rollers

• two oscillating rockers O1 and O2, moved in the shaft rotation, which maintain the

ADF (or ASF) in the position detached from the RS rollers, respectively through steps A or P).

Rotation to the RS shaft is imparted by motor M through a series of gear wheels,

rocker B1 and feeler pin T2 which supports rocker B2 (Fig. 2-18):

Fig. 2-18 Paper feed mechanisms

2-20

602E52970

A paper feeding cycle is started by the carriage against the left side. In this position, the motion shown in fig. 2-19 is started, which frees cam CRS (integral to the RS roller shaft) from feeler pin T1 of the rocker B1, and simultaneously accomplishes the connection between motor M and the cam (in detail) thus allowing the shaft to rotate:

Fig. 2-19 Paper feeding cycle start

Paper feeding conditions in the case of the ADF and in the case of the ASF are described separately below.

Original document feeding (ADF)

Motor M rotates counter-clockwise so that the CRS cam (and thus the RS roller shaft) rotates clockwise, allowing the original documents contained in the ADF to be fed (Fig. 2-20):

Fig. 2-20 Original document feeding

602E52970 2-21

During the first 360° of rotation of the CRS cam, the original is aligned against rear rollers RP which are still stationary because, thanks to feeler pin T2, neither one of the wheels R1 and R2 of the rocker B2 is engaged with the remaining mechanisms (Fig. 2-21):

Fig. 2-21 Original document alignment

Subsequently, the feeler T2 allows rocker B2, which is set in motion by friction, to transmit the motion to the rear rollers RP thanks to its wheel R2 (Fig. 2-22):

Fig. 2-22 Original document ejection

Received or copied document feeding (ASF)

Motor M rotates clockwise, so that cam CRS (and thus the RS roller shaft) rotates

counter-clockwise, allowing the paper in the ASF to be fed (Fig. 2-23):

Fig. 2-23 Received or copied document feeding

In this case as well, during the first 360° of rotation of the CRS cam, the paper is aligned against the rear rollers RP. Subsequently, feeler pin T2 allows rocker B2 to transmit motion to rear rollers RP thanks to its wheel R1. Note that rotation of the RP rollers is always counter-clockwise (Fig. 2-24):

3. INSTALLATION AND INITIALIZATION PROCEDURES

Installation of the facsimile machine consists of three separate phases:

1. PRELIMINARY OPERATIONS, or fitting together the parts supplied in the packaging and subsequent connection of the facsimile machine and telephone, if present, to the telephone network

2. INSTALLATION, or setting the parameters indispensable for the facsimile machine's operation.

3. SETUP, or setting the customization parameters.

3.1 PRELIMINARY OPERATIONS

3.1.1 Unpacking the Facsimile Machine

Having removed the facsimile machine and the other parts from the packaging,

check that the following elements are present:

• the facsimile machine (complete with power cord)

• a packet containing the print head

• the telephone cable (with two international RJ11 connectors)

• the handset (complete with connection cord)

• the telephone plug

• the paper support extension

602E52970

3.1.2 Connecting the Power Cord

Plug the power cord into the wall socket. The fax machine performs a brief self-test

and then shows the following message on the display:

CAUTION

: If the message does not appear in your language, carry out the

country setup procedure described in section 3.2.2 and continue with this procedure starting from the next step.

3.1.3 Inserting the Paper Support Extension

Insert the paper support extension in its slot pushing downward until you hear the

latching click.

3.1.4 Paper Supply

When supplying the paper to print received and copied documents, always pay attention to the following two factors, which must always coincide to guarantee that the print is properly contained within the width of the sheet in use:

AUTOMATIC RX CHECK PRINT HEAD

602E52970 3-3

- paper format, i.e. width of the sheet in use

- print format, i.e. the value of the FORMAT parameter in the PRINT PARAMETERS menu (see sect. 3.2.1).

1) Insert the sheets without going beyond the maximum quantity indicator notch, letting them fall into the tray without bending or forcing them.

2) Push the sheets against the left side of the tray using the adjustment lever.

CAUTION:When you need to add paper in the tray, insert the sheets under those

already present.

3) Set the FORMAT parameter of the PRINT PARAMETERS menu to the value corresponding to the format of the paper (see sect. 3.2.1)

3.1.5 Installing the Print Head

1) Flip open the printer lid

7) If the CHECK PRINT HEAD appears again, remove the print head pulling the small levers forward:

NEW PRINT HEAD?

1=YES 0=NO

3-6

602E52970

and visually check for the presence of a particle on the print nib: if so, remove the particle with care, without touching the electrical contacts. If not, the facsimile machine automatically loads a sheet of paper and starts the nozzle cleaning and checking procedure, which ends by:

• printing out the following print chart on the automatically loaded sheet

(*)

which contains:

− a numbered scale, for checking the flow of ink and the electrical

circuits controlling the print head nozzles

− a section of graphics and text, for evaluating print quality

numbered scale

602E52970 3-7

(*) only if bit 2 of SW09 is set to 1.

• the following message appears

8) Analyse the print chart as follows:

• Check that there are no gaps in the numbered scale and that there are no

horizontal white lines in the black areas: under these conditions, which

indicate that the print head has been inserted correctly and is in perfect working order, type 1: the facsimile machine returns to stand-by and is ready for use

• If there are gaps or white lines, type 0 to repeat the nozzle cleaning

procedure: if the new print chart is still unsatisfactory, repeat the procedure again

• If the printing quality is still not up to the required standard after the proce-

dure has been performed three times, proceed as follows until a satisfactory print chart is obtained:

- Make a copy of a document with the desired type of graphics and text and assess its quality.

- Change the type of paper (the paper you are using may be too porous) and repeat the procedure.

- Remove and reinsert the print head.

- Remove the print head and check that there is no foreign body on the printing nib; if there is, remove it with care, taking care not to touch the electrical contacts; slide the print carriage to the right, then clean the print head cleaning pad using a cotton swab soaked in water, taking care not to leave any fluff;

4. SERVICE SWITCHES

The term service switches is intended to mean parameters that cannot be accessed by the user and that can only be accessed by service technicians with

the facsimile machine in "service" mode (see section 3.2.2).

These parameters are given default values which depend on the country specifications made by the telephone network manager. As a result, the technician should only change these values in order to correct the functioning of the machine or to adapt it to particular local features.

Before changing any of the service switch settings, it is advisable to print them, as described below:

Setting

a) The facsimile machine is in standby mode

b) Access the main menu and select the SERVICE

SWITCHES submenu of the INSTALLATION menu

c) Press

d) Enter the number 5 0 0 and press to enter "service

Fig. 4-1 Example of a printout of the service switch settings

Two types of service switches are available in the SERVICE SWITCHES menu:

- SW01 - SW11: these switches consist of 8 bits and can be programmed either individually or in group

bit no. 76543210

- SWA - SWR: these switches consist of a value ranging

from 1 to 3 digits

Warning: 1) Whenever no value is printed in correspondence with a service

switch SWA-SWR, this means that the value is 0 (zero).

2) Some of the service switches can be set by the user; in these cases, the user setting takes priority over the service setting. The parameters concerned are:

4.1 SERVICE SWITCH TABLES

The tables that follow describe the functions carried out by the bits and combinations of bits for each service switch. In order to correctly interpret some of the functions required, a knowledge of the communication protocol is required. The default values may undergo some modifications due to both homologation and user's peculiarities. For this reason, you are recommended to print out the service switches of the facsimile machine to be serviced, always before modifying them.

5. DIAGNOSTICS

5.1 SELF-DIAGNOSTICS

The facsimile machine automatically runs a diagnostic program (SELFDIAGNOSTIC TEST) the first time it is powered on and on reactivation after a power failure or disconnection from the mains:

- if the self-diagnostic test is passed, the facsimile machine enters standby

mode

- If instead the self-diagnostic test is failed, the fax machine shows an error code on the display (SYSTEM ERROR xx). In this case, the fax machine needs to be disconnected from the power supply socket before eliminating the related problem.

The self-diagnostic routine tests the following components:

• EPROM

• static RAM

• printer.

5-2 602E52970

The self-diagnostic test stops at the first test in which a fault is detected.

5.1.1 Description of the Self-Diagnostic Program

Diagnostic step Error message

1) The facsimile machine is powered on: the error LED lights up

2) The EPROM is tested

3) The static RAM is tested

4) Printer startup: check that the print carriage is reset.

5) The paper edge sensor is tested.

6) Self-diagnostic program ended successfully: error LED switches off.

(1) To solve this problem, replace the EPROM.

(2) This error means that the data of the static memory have been damaged, so U.K./

S. AFRICA country software parameters have automatically been loaded. To solve this problem, proceed as follows:

- disconnect and reconnect the fax machine from the power supply socket: if the

error message persists, replace first the rechargeable battery then, if the error still persists, replace the motherboard. If instead the message disappears, proceed as follows:

- perform LOAD DEFAULT (see sect. 6.1.7), ALIGNMENT TEST (see sect. 6.1.1)

and SCANNER SHADING (see sect. 6.1.8) procedures

- perform fax machine nationalisation and reset installation and configuration

parameters (see sect. 3.2).

(3) This problem could be caused by the absence of the carriage limit stop plate (right

side), by the paper edge sensor (replace carriage) or by a failure in the carriage motor (replace the defective part: motor, belt, etc.).

4) This problem could be caused by the absence of the carriage limit stop plate (right

side) or by the paper edge sensor (replace the carriage).

5.2 ERROR CODES

The error codes are printed on the journals (see section 5.3).

The format of these error codes, excluding those referring to the self-diagnostic test

(described in section 5.1.1), may be:

- one group of two digits (xx)

- two groups of two digits separated by a dot (xx.xx); this extended format:

• indicates the category to which the error belongs, by means of the first

group,:

01 Document incorrectly positioned 02 Unable to connect 03 No answer from correspondent 04 Failed transmission 05 Incomplete transmission 07 Document too long 08 Document jam 10 Failed or incomplete reception 11 No reception due to memory full 13 Failed polling reception 16 Power failure

• provides more detailed information about the error, by means of the

second group, and may be requested by the technician with the machine in

"service" mode (see section 3.2.2), by setting bit 0 of switch SW09 to 1 (see section 4.1).

In the tables that follow, the error codes are indicated in their extended format and

in ascending numeric order.

For an explanation of the meaning of the protocol signal codes that appear in the

description of the causes of errors, see the next section (5.2.1).

Important: to ensure correct identification of the cause of the error, we recom-

5-4 602E52970

5.3 REPORTS

The facsimile machine controls and updates various kinds of transaction reports which are described in this section for the technician's benefit, though a more detailed description is provided in the Instruction manual. Some of these reports are printed automatically and others on request by the operator:

• Transmission report (LAST TX REPORT): printed automatically and manually

• Broadcast transmission report (LAST BROAD. REP.): printed automatically and

manually

• Journal (ACTIVITY REPORT): printed automatically and manually

• Power failure report: printed automatically only.

A report is printed by selecting the PRINT OUT REPORT option on the main menu (see section 3.2.1).

5.3.1 Transmission Report (TX REPORT)

The methods for printing the transmission report (automatically or manually) are selected by means of the SET MISCELLANEOUS option of the FAX SET-UP menu (see section 3.2.1):

• TX REPORT: OFF, if you do not want the report to be printed automatically

• TX REPORT: ALWAYS, if you want the report to be printed automatically after

each transmission transaction

• FAILED TX REPORT, if you want the report to be printed automatically only

when an error is detected (*).

5-12 602E52970

(*) if bit 3 of switch SW07 is set to 1 (see section 4.1), the report is always printed

when transmission is failed even if the TX REPORT: OFF option is selected.

The transmission report contains the following information (fig. 5-5):

Fig. 5-5

• Act. n. progressive number of activity or transaction (4 digits)

• Type transaction (TX / TX ECM / RX / RX ECM / POLL / POLL ECM)

• Dialled correspondent's number dialled

number

• Received correspondent's number (and name, if recorded)

Id (*)

• Date/Time date and time of start of transaction

• Duration duration of transaction (minutes : seconds)

• Page number of pages in document

• Result result of transaction (OK / error code).

(*) this is the ID recorded on the correspondent's facsimile machine, the numeric

part of which should correspond to the actual telephone number of the fac-

602E52970 5-13

simile machine: if it does not, call the correspondent and ask him/her to correct the ID.

5.3.2 Journal (ACTIVITY REPORT)

Provides information about all transactions (transmission / reception) and is printed automatically every 32 transactions (and the information printed is subsequently cleared from the memory) or on request by the operator (fig. 5-6):

Fig. 5-6

5.3.3 Loss of Mains Power Supply Report

When operating conditions are restored after a loss of mains power supply, the fax machine may behave in three different ways:

• if power was lost during a transaction (transmission or reception), then a report

with the transmission data will automatically be printed (fig. 5-7):

Fig. 5-7

5-14 602E52970

or with the reception data (fig. 5-8):

Fig. 5-8

• if power was lost during reception and the received document was damaged,

the same report as in fig. 5-8 is printed, with the addition of data pertaining to the last 16 receptions (fig. 5-9):

Fig. 5-9

• if power was lost after a substitute reception and the document still in

memory is damaged, a report is automatically printed with the data for the last

16 receptions (fig. 5-10):

602E52970 5-15

no shadings should result in the strip

• area 3 is used for checking vertical alignment; run the printer alignment test, if

necessary, to modify the alignment parameters (see section 6.1.1)

• areas 4, 5 and 7 are used for checking that the line feed mechanism is uniform:

- in area 4, groups of lines are printed close together but must never cross or overlap (

); the groups alternate in lines corresponding to the

central nozzle on the print head (number 25)

- in area 5, groups of lines are printed one on top of another and there must be no space between them (

); the groups alternate in lines

corresponding to the central nozzle on the print head (number 25)

- in area 7 dark grey and light grey patterns are printed forming a uniform strip, that is, without black or white lines distributed irregularly across it; if the lines appear at regular intervals along the strips, some of the nozzles are faulty

Faults found in areas 4, 5 and 7 indicate line feed errors

• four areas 6 are used for checking "all black" printing; check that there are no

white lines present; if there are, some print nozzles may be blocked. In this case, run CLEANING (see section 6.1.3)

• area 8 is used for checking the printing of ASCII characters

• area 9 is used for checking printing with the nozzles spraying at maximum

frequency: there must be no white or broken lines; if there are, run the nozzles test (see section 6.1.2).

7.1 MAINTENANCE

The facsimile machine's maintenance includes periodic preventive procedures (such as optical unit cleaning), and action to be taken following a message on the display (such as the ink out message): the procedures are normally carried out by the user so they will be described in detail in the User Guide. Here only a brief description is provided.

7.1.1 OUT OF INK Message

The facsimile machine has a built-in counter for keeping track of ink consumption, so as to provide an ink out message at the right time. When the ink present in the cartridge runs out, the display shows the following message:

OUT OF INK

to prompt the operator to:

- replace the ink cartridge, if the print head is of the rechargeable type

- replace the entire print head, if it is of the disposable type.

If a rechargeable print head is used, the ink cartridge can be replaced several times. When a deterioration in the printing quality is observed, after several replacements, this means that the entire print head is to be replaced.

While replacing the cartridge only, but not the entire print head, a little ink may be ejected, to prevent the printing area from getting dirty, when the out of ink message appears, a sheet of paper is automatically inserted under the print carriage.

7. MAINTENANCE AND REPLACEMENT PROCEDURES

7-2 602E52970

7.1.2 Replacing the rechargeable Ink Cartridge

1. Tilt the printer cover.

2. Remove the used cartridge, without removing the print head, by pressing the catch.

3. Remove the new cartridge from its sealed packing and peel the protective film off the ink supply hole.

4.Insert the cartridge in its housing immediately and press it in until the catch clicks

into place to indicate that the cartridge is correctly inserted.

5.Close the printer cover: if the head cleaning feature is enabled (bit 2 of software

parameter SW09 =1, see section 4.1), the facsimile machine automatically starts the nozzle cleaning and testing procedure (see section 3.1.5, step 7). If it is not, the sheet of paper is unloaded.

WARNING

Do not touch the inked area!

7.1.3 Replacing the Print Head

See section 3.1.5 (starting from step 4).

7.1.4 Cleaning the Print Head

If print quality deteriorates, the print nozzles need to be tested first (see sect. 6.1.2) to determine whether it is necessary to perform the print head CLEARING procedure, which entails drawing ink to free the print head from any air bubbles it may contain.
