Cranex D Ceph beam alignment procedure (White Panel Unit Only)
This procedure is a quick guide that goes through the beam alignment
procedure. To make this easier, the tech should have the beam
alignment tool (Part # 203603) when performing the alignment.
Step#1: Be sure the main pan unit, ceph arm and head are level
before beginning.

Select Sr 11 EPS and press the E key and let
go (do not hold the button).
Press the left or right upper arch button to
select the different technique factors and
exposure time.

Step #4: Remove the secondary collimator from the Ceph head by
removing the lock bolts and unplugging the ribbon cable.
Step #5: With the unit now in EPS mode and centered, make sure the
display reads 85 kV, 10 mA and 2.00 seconds. This gives you a
long enough exposure time to see the beam.

Step #6: Take an exposure, what’s needed is for the beam to
be within the Two outer vertical lines on the beam alignment
tool and also at the bottom line as shown below. Remember
the secondary collimator is off

Step #7: If the beam is not within the lines horizontally, Loosen the
Four Torx screws that hold the Ceph head onto the arm. Slide the
head in or out until the beam is centered properly. Be sure to lock the
screws down once the beam is aligned.

Step #8: If the beam is not touching the bottom line in the tool, loosen
the Two bolts on the collimator that is in front of the
tubehead and then adjust both alignment screws. Be sure to
adjust these screws the same amount so the beam stays level.

Step #9: With the beam now centered, reattach the secondary
collimator and ribbon cable.
Step #10: With the unit still in EPS mode and the beam tool attached
to the ceph sensor, take another exposure. The beam needs to fall on
the entire Three inner vertical lines on the beam tool and also on the
bottom line. If the beam is way off, redo steps 7,8 and 9 again to
ensure the beam is correctly aligned

Step #11: If the beam is out of alignment, then do the following:
Horizontal alignment:
A. Loosen the screw on the belt cog wheel
B. Insert a slotted screwdriver into the cog wheel end, while
holding the belt turn the screw in the desired direction to get the
secondary aligned properly.

Vertical alignment:
C. If the beam is above or below the bottom horizontal line, loosen
the Two mounting screws and then adjust the top screw.
Tilt:
D. If the beam is going in a diagonal direction, adjust the side screw
to get the beam straight.
