Maintaining the powder cartridge

During regular use, the powder cartridge becomes saturated with powder and needs to be

cleaned. The powder cartridge should be cleaned after processing approximately 50–100

prints, or if powder starts leaking, whichever comes first.

To maintain the powder cartridge:

1. Open the cartridge valve.

2. Attach the vacuum crevice tool to the vacuum hose in the Fuse Sift.

3. Wedge the vacuum crevice tool under the middle-left of the valve knife.

4. Turn on the vacuum by pushing the Vac button on the control panel or by tapping the

vacuum hose icon on the touchscreen.

5. Hold the vacuum crevice tool in place for approximately one minute.

6. Move the vacuum crevice tool to the middle-right of the valve knife and hold in place

for approximately one minute.

7. Move the vacuum crevice tool to the far right of the valve knife and hold in place for

approximately 30 seconds.

8. Move the vacuum crevice tool to the far left of the valve knife and hold in place for

approximately 30 seconds.

9. Remove the vacuum crevice tool from underneath the valve knife and close the

cartridge valve.

10. Turn off the vacuum by pushing the Vac button on the control panel or by tapping the

vacuum hose icon on the touchscreen.
