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.
