diffuser plate with the blower brush.
If there are large debris particles on the
light diffuser plate, use tweezers to
remove them.
2. Next, remove any dust on the half mirror
and lens with the blower brush.
If there are large debris particles on the
lens, remove them with tweezers by
inserting them through the opening

CAUTION
The light diffuser plate is a very thin sheet. Be careful not
to apply force or scratch the surface with hard objects
such as tweezers.
Reference
Depending on the machine specifications, there might
be no space allowing access to the lens from the rear
side of the camera unit. This makes it difficult to clean
the lens without disassembling the units around the
camera unit. In such cases, contact our local sales
office or sales representative for assistance.

2.6 Inspecting ball screws and linear guides of each axis
Inspect the ball screws and the linear guides on the X, Y and W axes. Check the following points.
Checkpoints
1. Any foreign matter adhering to the ball screws and linear guides?
Check if any fallen chips have adhered to the X and Y axis ball screws and/or X, Y and W axis linear guides.
2. Do the ball screws and linear guides have the correct amount of grease?
Check if grease has flowed off or splattered in the air failing to adhere. Also check if grease has discolored or hardened.
3. Any abnormal sounds from the ball screws?
Press the emergency stop button. Then check for any abnormal sounds while pressing the head assembly or conveyor
table by hand along the X-axis or Y-axis back and forth.
Countermeasures
1. Ball screws and linear guides may be damaged when chips and other material bite into them. If chips are adhering,
wipe them off along with the grease or remove with tweezers, etc.
2. Apply grease while referring section 2.2, "Cleaning and greasing the X, Y and W axes" explained in this chapter.
3. Consult your YAMAHA sales office or representative when abnormal sounds occur even after trying the
countermeasures in the above steps 1 and 2.
