state.
Powder Xfer Off

TRANSPORT switch is OFF , the BOS enters the
Powder Xfer Off state. If you turn the POWDER
TRANSPORT switch to RECYCLE or DISPOSAL ,
the BOS switches to the In Standby state.
Xfer to Sifter
If you press in the In Standby state and the
sifter is empty (i.e., the sifter level sensor is off;
there’s no powder to send), the BOS enters the
Xfer to Sifter state and runs the sifter until the
sifter is full (i.e., the level sensor switches on). If
the sifter doesn’t fill in 2 minutes or less, the BOS
returns to the
