specifi c times (for example after 30 trans-
missions).
Memory:
If there is no paper or toner in
your fax machine, the machine will store
incoming fax transmissions in its memory.
SMS messages are stored in the SMS
memory.
Modem:
A modem converts digital compu-
ter signals into acoustic signals and vice
versa. Analogue telephone lines transfer
only acoustic signals, not digital signals
(see Hard Modem, see Soft Modem).
Outside Line Access Code:
line access code is the number or letter that
must be dialled before the actual telephone
number on a telephone of a private branch
exchange in order to establish a connec-
tion to the public telephone network (see
Private Branch Exchange).

see Additional
Devices
Plug'n'Print Card:
Smart card used to set
the toner level memory to full after install-
ing a new toner cartridge.

Private Branch Exchange:
branch exchanges are common in larger
companies. Even private ISDN systems
can be branch exchanges. To establish a
connection to the public telephone net-
work from a private branch exchange, one
must dial a number or press a key before
the actual telephone number; in most cases
this is zero (see Outside Line Access Code).
Pulse Dialling:
see Tone Dialling
Resolution:
Number of dots per inch (dpi).
For sending and receiving faxes, the reso-
lution options available are Normal, Fine,
SFine and Photo. For copying, the avail-
able resolutions are Fast, Quality and Pho-

takes to complete the transmission.
Scanning:
Th e reading of a document into
the fax memory or into the computer in
order to send it, copy it or edit it.
