Tell me about preventive maintenance
During the life of your printer, components that are used constantly can wear out with
time and use.
To avoid these components being so worn that the printer breaks down, the printer
keeps track of the number of cycles the printer carriage makes across the axis of the
printer and on the total quantity of ink printed.
The printer uses this number to advise you of the need for preventive maintenance,
displaying one of the following messages on the front panel:
●
Maintenance #1 required
● Maintenance #2 required
These messages mean that some components are nearing the end of their lives. You
can continue printing for quite some time, depending on your use of the printer.
However it is strongly recommended that you contact your customer service
representative and arrange for a preventive maintenance on-site visit. The service
engineer can then replace the worn parts, which will prolong the life of the printer for a
further period.
The benefits of arranging a service engineer's visit when the front panel displays
these messages are two-fold:
●
The printer components can be replaced at a time that is convenient for you and
so will not disturb your daily workflow.
● When the service engineer performs a preventive maintenance visit he will
replace several parts at once. This will avoid the need for repeat visits.
