Replacing the Material Filters
Filters are installed in the lines that supply Model material to the print heads. To
ensure that the heads remain in optimum condition, the filters are replaced by
your service provider, as part of the scheduled maintenance routine. However,
filters used for certain materials need to be replaced more often. A counter keeps
track of the amount of material passing through the filters, and the
Maintenance
Required
indicator appears in the printer interface when it is time to replace a
filter. The counter for RGD515 material, for example, is set to notify you after 20
hours of use. This is enough, on average, for about a year of printing.
To check the material-filter counters, open the
Maintenance Counters
screen
(see "Maintenance Counters" on page 4-32) and scroll down to the
Filters
section.
