Smart card incidents
The table in this section presents problems that may occur reading smart cards and their causes. 
Communication failures
Communication failures may occur when scanning or sending a document.
If the communication fails, the machine will automatically reattempt to make the call later.
Scanning failure
You can:
• resend the document immediately by pressing  , if the document is still present;
• cancel the operation by pressing  .Printing on 
transparencies 
lacks clarityThe transparencies used are not 
compatible (format, thickness, 
type, etc.).Only use compatible media supports (see 
Recommendations for the paper [129]).
The transparencies are not 
correctly loaded in the paper 
tray(s).Remove the transparencies from the paper tray and 
align their front edges.
Replace them in the paper tray and adjust the guides 
against the stack of transparencies (see Loading 
transparencies into the paper tray [11]).
Printing on

Sending failure
You can:
• wait for the machine to attempt to send the document again;
• send the document again immediately via the emission queue (see section Forcing an emission request [52]);
• cancel the operation by deleting the corresponding request from the emission queue (see section Deleting a 
document awaiting emission [52]).
The machine will make 5 automatic call-back attempts. The unsent document is automatically deleted and an emission 
report is printed with a failure code and the reason why the communication failed.
Communication failure codes
The communication failure codes appear in logs and emission reports.
General codes
 
CodeMeaningReason / Solution
01 Busy or no fax answerThis code appears after 6 unsuccessful attempts. You should 
try again later.
02 Busy or no fax answerThis code appears after 6 unsuccessful attempts. You should 
try again later.
03 Operator stopThe communication was interrupted by the user by pressing 
.
04 Non programmed numberA number saved as a one-touch key or abbreviated number is 
not valid, check it. (Example: a delayed transmission was 
programmed with a one-touch key and this key has been 
deleted in the meantime).
07 DisconnectionThe communication was cut off (bad quality link). Check the 
number.
08 QualityThe document you sent was not properly received. Contact 
your correspondent to see whether it is necessary to resend the 
document. It is possible the interference occurred in a useless 
part of the document.
12 Document receive errorAsk your correspondent to check the length of the document (it 
is too long to be received in full).
13 Document incorrectly sentAsk your caller to send the document again.
15 Incompatible codingRecipient machine does not match with the send document’s 
encoding.
19 Memory saturatedThe machine can no longer receive as the memory is full. There 
are too many unprinted documents or documents waiting to be 
sent.
Print out the documents received and immediately send or 
delete documents waiting to be sent.
20 Memory saturatedReceived documents memory saturated. Print out received 
documents.
25 Caller stopThe communication was stopped by the caller.
26 DisconnectionSending did not start. The telephone line is too noisy.
27 Document incorrectly sentƒFor emission: send the document again.
ƒFor reception: ask your caller to send the document again.

Safety Instructions
 Before connecting your machine, check that the mains plug to which you are connecting the machine complies 
with the indications on the information label (voltage, current, frequency of electricity network) on the machine. This 
machine must be connected to a single-phase mains power supply. The machine should not be installed directly on 
the ground.
Batteries, packaging and electrical and electronic equipment (EEE), must be disposed of in accordance with the 
instructions in the ENVIRONMENT chapter in this manual.
Depending on the model, the machines power plug may be the only means of disconnecting from the electricity 
supply. As a result, the following precautions must be taken: the machine must be connected to a nearby power plug. 
The power plug must remain easily accessible.
The machine is supplied with a mains power cable fitted with an earthed plug. An earthed power plug must be 
connected to a wall socket fitted with an earth connected to the building earth protection.
 
For installation conditions and precautions for use, please consult chapter Installation [8].
Laser Safety Information
CAUTION: The use of controls, adjustments or performance of procedures other than those specified in this 
guide may result in hazardous light exposure.
This equipment complies with international safety standards and is classified as a Class 1 Laser Product.
With specific reference to lasers, the equipment complies with laser product performance standards set by 
governmental, national and international agencies as a Class 1 laser product. It does not emit hazardous radiation as 
the beam is totally enclosed during all phases of customer operation and maintenance.
For Europe/Asia
This machine complies with EN 60825-1:2007, is classified as class 1 Product and is safe for office/EDP use. It 
contains a laser diode of 10mW power and wavelength 785nm.
Direct (or indirect reflected) eye contact with the laser beam may cause serious eye damage. Safety precautions and 
interlock mechanisms have been designed to prevent any possible customer exposure to laser radiation.Repair-maintenance: Have any repair and maintenance work carried out by a 
qualified technician. It is prohibited for users to repair internal components. To 
prevent all risk of electrocution, you should not conduct these operations 
yourself, as by opening or removing covers, you are exposed to a double risk:
ƒIrremediable injury may be caused to the human eye if it is exposed to laser 
rays.
ƒContact with powered components may cause electrical shock with extreme-
ly serious consequences.
