Tube Head Control Cable Replacement

Required Tools:

5.5.1 Procedure

1.Switch off the power to the scanner.
2. Remove the tabletop, head and foot end panels. At the foot end of the scan
table unplug the A/C power plug to the scanner.
3.Move the scan arm to the head end of the table.
4.Take the black tape off the high voltage cable bundle at each end of the
sleeving (open any cable track clips that are in the way as in step 8) as well as
any wire ties holding the bundle in place. Next, slide the sleeving away from
the tube head and remove the tape beneath the sleeving. Note the positions
of each cable before removing the tape. The cables must be returned to these
positions.
5.Disconnect the military-style connector and the ground wire (if one exists)
from the tube head and slide the cable out of the black sleeving toward the
cable track.
6.Unplug J3 and J5 on the XORB board. Also, trace the ground wire (if one
exists) from the control cable and disconnect it from the power supply. Cut the
wire ties holding the control cable to the pan.
7.Pry open the plastic retaining clips that hold the cables into the cable track.
These clips pivot at the back of the cable track and can either be removed or
left in the open position to remove the cables. The screw located at the end of
the cable track near the pan must also be removed. Once this screw is
removed the cable track can be lifted out of the channel it rides in and the
remaining clips can be opened. Mark the position of the cable track screw on
the frame to return the track to its original position.
8.Remove the old control cable. Note the position of all the cables in the cable
track. They will need to be returned to the same position during this
procedure.
