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 4-40) and scroll down to the Filters
section.
