Mixer Error

Cause
• The breaker switch on the
vacuum is set to OFF
• The vacuum is not
connected to the machine
• The vent filter is not
installed correctly
• One of the vent filter
occupancy switches is not
being triggered
Too much powder has
accumulated in the used
powder hopper, preventing
the sifter from running.
A powder cartridge inserted
into the drawer either weighs
too much or too little to be
accurately filled.
The mixer is blocked by
an obstruction.
The drive belt or pulley
for the mixer is loose
or misaligned.
Solution
1. Check whether the breaker switch on
the vacuum is in the ON position.
2. Check whether the vacuum hose is
attached to the port on the side of
the machine.
1. Remove the vent filter.
2. Reinsert the vent filter.
1. Run at least one cartridge filling
operation at a 0% refresh rate.
2. Deposit the excess used powder into
a large container with a lid.
Do not dispose of excess unsintered
used powder in general or recycling
waste streams.
1. Check whether the powder cartridge
is completely empty before loading it
into the cartridge drawer.
2. Clean out any powder that has
collected in the cartridge drawer itself.
3. After confirming both the powder
cartridge and cartridge drawer are
clean, tare the cartridge drawer
scale. Tap the wrench icon on the
touchscreen. The Settings screen
appears. Tap Maintenance > Tare Fill
Scales > Tare.
4. Place the powder cartridge in the
cartridge drawer and try filling the
cartridge again.
Check the mixer for obstructions.
If the error persists, contact
Support or a certified service provider
