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 consump-
tion, 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.
(*)
Two counters on the
LinkFax
model, one for the monochrome print head and
another for the colour print head.
