manually to their upper ends.
2.
Move the scan camera to the right side of
the R-axis motor. At this point, do not
apply excessive force to the scan camera.
n
NOTE
When the machine has only one fiducial camera, moving
the scan camera to the left end will make cleaning easier
.

Wipe the diffuser plate and prism.
1.
Use a cotton swab to remove dust and
dirt on the upper surface of the main light
diffuser plate and on the prism surface. As
the prism surface is narrow, twist the end
of the cotton swab into a pointed tip and
use it to wipe the prism surface lightly.
2.
Wipe the side-view light diffuser plate and
prism with a cotton swab. Use a hand
mirror when wiping the prism surface as it
cannot be seen from the front.

5.3 Cleaning and lubricating the W-axis
Every six months, cleaning and lubrication of the ball screw, guide, and hex spline of W axis are necessary. For
lubrication locations, see "Chapter 5 Lubrication points and schedule". For lubrication of the dual stage W2
axis (U axis), see "4.8 Dual stage only: Cleaning and lubrication of U axis (W2 axis)" in this chapter.

Change the conveyor width to its
maximum width.
1. Press the [Conveyor Width] button on the
[Unit] – [Conveyor] screen to display the
“Conveyor Width” screen.
2. Enter the maximum value of the
conveyor width in the “Changed
conveyor width”, press [OK]. The
conveyor is changed to the width that
was just entered.

TIP
The maximum value of the conveyor width is 460 mm
for the single lane and dual stage specifications. In
case of the dual lane specification, the maximum value
of the conveyor width in one side lane is 382 mm. Enter
382 mm on lane 1.

Clean the each part of W-axis.
1. Press the emergency stop button, and
open the machine’s safety cover.
2. If the machine is equipped with a
carriage, remove to the carriage for
easy access to the w-axis.
3. Remove everything affected by
magnetism such as wrist watches,
magnetic ID card, etc.
4. Wipe the old grease and soiling from the
W-axis ball screw, guide, and the whole
hexagon spline with a lint-free cloth that
does not raise dust.

NOTE
When performing cleaning, clean the lead groove part
of the ball screw and the groove of the guide rail
carefully. Also, make sure no dust is generated.
n
NOTE
The number of cleaning areas (ball screw, guide, and
hex spline) differs depending on the specification of
the machine. See "Chapter 5 Lubrication points and
schedule".
