Y Camera Home Positioning
WARNING
BOARD CLAMPS. EXTREME CARE MUST BE EXERCISED WHEN
WORKING IN THE TOOLING AREA OF THE MACHINE TO AVOID
INJURY. THE FOILS ON THE FRONT AND REAR BOARD CLAMPS
ARE VERY SHARP.
1. In Diagnostics select Camera Axes module.
2. Select Home Camera X Axis. Select Home Camera Y Axis.
3. Release the Y servo motor from its drive belt. With the motor pulley now
disengaged, move the camera carriage by hand until a gap of 28mm - 30mm
is measured between the camera carriage and the Y axis carriage support
member.
4. Carefully refit and tension the belt (see Left Hand Main Y Axis Timing Belt
Replacement Procedure). Tighten the belt tensioning member and motor
screws.
5. Select Home Camera X Axis. Select Home Camera Y Axis. Confirm the
home position setting is correct.
6. Set the vane 1 - 2mm beyond the sensor.
7. Carry out the following checks:
a. Camera X Axis Parallelism
b. Camera Reference Position.
This completes the mechanical home setup for the camera carriage.

X Axis Parallelism
WARNING
BOARD CLAMPS. EXTREME CARE MUST BE EXERCISED WHEN
WORKING IN THE TOOLING AREA OF THE MACHINE TO AVOID
INJURY. THE FOILS ON THE FRONT AND REAR BOARD CLAMPS
ARE VERY SHARP.
NOTE
The X Axis Parallelism is factory set and shouldn’t normally need to be adjusted.
1. In Camera Diagnostics, home the Camera X axis and Y axis.
NOTE
Check the physical position of the camera to ensure that it is clear of the
rails.
2. Select Raise Table to Print Height in Rising Table Diagnostics.
3. Raise the printhead and insert the head prop. Select Close System and Power
down the machine.
4. Carry out either of the following:
a. Move the camera carriage forward by hand to facilitate removal of camera
assembly from the camera carriage. Remove the camera, (Camera
Replacement Procedure refers).
b. If available, fit a spare camera carriage bearing to the right hand end of the
camera rail.
5. Fit a Dial Test Indicator (DTI) to the camera carriage bearing.
6. Using the DTI check the camera carriage for parallelism to the rear rising
table linear guides to within ±0.127mm.
7. If adjustment is necessary, carry out the following:
a. Loosen the left hand camera Y belt clamp securing screws (in eight
positions).
b. Adjust the carriage until parallelism is achieved.
c. Tighten the belt clamp screws.
d. Recheck carriage parallelism. Repeat Steps 7a - 7d if adjustment is still
necessary.

8. When adjustment is complete, remove each belt clamp screw disturbed one
at a time, apply suitable locking compound and fully tighten. Recheck
parallelism of camera carriage.
9. Remove DTI from the camera bearing.
10.Carry out either of the following:
a. Refit the camera (Camera Replacement Procedure refers).
b. Remove the spare bearing from the camera rail.
11.Reposition the camera carriage to the home position by hand.

a. Carry out checks in Camera Replacement Procedure, (Checks and Tests).
b. Carry out Home Camera Axis X and axis Y.
Y Axis Parallelism
WARNING
BOARD CLAMPS. EXTREME CARE MUST BE EXERCISED WHEN
WORKING IN THE TOOLING AREA OF THE MACHINE TO AVOID
INJURY. THE FOILS ON THE FRONT AND REAR BOARD CLAMPS
ARE VERY SHARP.
NOTE
The Y Axis Parallelism is factory set and shouldn’t normally need to be adjusted.
It is recommended this procedure is carried out by two persons.
1. In Rail System Diagnostics, select Home Rail Width.
2. Raise the printhead and fit the head prop. Select Close System and power
down the machine.
3. Using a 1000mm vernier caliper, check the camera Y axis parallelism.
Ensure the vernier is reading directly from the Y camera linear bearing.
