6.4.4 Cleaning the intake filter
The Fuse 1 uses a filter to remove contaminants from air being drawn into the printer. The
intake filter should be cleaned every 30 hours of printing, whichever comes first. Used filters
that have experienced 20 prints or 400 hours of printing should be cleaned after every print
to extend their lifetime.

a. Navigate to the filter maintenance procedure by tapping the checklist icon on the Print
Status screen, or
b. Drag the Open Door slider on the touchscreen.

snap-fit tabs. Remove the filter from the filter cabinet.

vacuum hose icon on the touchscreen.

on the mount inside the cabinet. Twist the filter clockwise to lock it in place.
