MONTHLY MAINTENANCE

CLEAN/INSPECT TIP WIPE ASSEMBLIES

The tip wipe assemblies should be cleaned once a month. While cleaning the assemblies, inspect the flicker/
brush assemblies for wear and replace as necessary when wear is detected.
Once material is purged from a tip, the flicker portion of the tip wipe assembly passes across the tip's opening,
cutting purged material off in small segments. The brush portion of the tip wipe assembly then passes across
the tip's opening cleaning the tip and its tip shield. As a result, the flicker will wear at the location where the tip
contacts its surface and eventually develop a notch large enough for the tip to completely pass through the
flicker; a notched flicker cannot properly cut purging material. Similarly, material can become embedded within
the bristles of the brush resulting in clumping; clumped bristles cannot properly clean a tip or its tip shield. The
tip wipe assembly should be replaced once a significant notch develops within the flicker portion of the
assembly or whenever bristle clumping (which cannot be removed with a brush) is apparent within the brush
portion of the assembly. The tip wipe assembly is replaced as a single unit.
To clean the tip wipe assembly and inspect its components:
1. Ensure that the printer is stopped (idle) and is not building.
2. Open the oven door.
Hot Surface: Depending on how long the oven has been allowed to cool,
components may be hot. Wear the safety gloves provided in the Welcome Kit to
perform all remaining steps.
3. Remove the model side tip wipe assembly by lifting it upward until it clears its locating pins.
