large enough for maintenance work
(about 200mm) and press [OK].
The conveyor is changed to the width

3
Remove the conveyor belt.
Remove the conveyor belt from the pulley
and the belt groove of the board guide.
4
Check for wear on the board
conveying side of the conveyor belt.
After removing the belt in step 3, check for
wear on the board conveying side of that
conveyor belt.
TIP
About half (3 to 4 mm) the belt width is used for board
conveying. If the board conveying side of the conveyor
belt is worn, then you can still reuse the belt by switching
the used side with the opposite side. However, this will
cause errors after long-term use, so early belt
replacement is recommended.
5
Clean the pulley and the belt
groove on the board guide.
Using a vacuum cleaner or similar device,
suction up the belt wear dust deposited in
the belt groove or on the sensor surface. Also
use a vacuum cleaner while brushing debris
away with the brush supplied with the
machine.
Also clean the pulley and other parts for the
conveyor belt.

Move the head all the way to the
front end of the Y axis.
On the [Unit]-[Head] tab (or [conveyor] tab)
screen, press the [Axis] button to open the
"Move Axis" screen. Then move the head
assembly all the way to the front of the Y
axis (front of machine).
TIP
The ejector unit is located at the front of the head
assembly. It is easier to inspect the ejector filters when
the head assembly is positioned to the front side of the
Y axis. (Inspect the ejector filters from the front of the
machine.)

2
Press the emergency stop button.
The machine should be in emergency stop
to ensure safety during work.

Clean the filter.
Use tweezers to take the filter out of the
ejector. When there is only a little dust in the
filter, use an air blow gun to blow it away
and return the filter back to the original
position.

NOTE
If there are heavy dust deposits in the filter or the filter
has discolored, replace it with a new filter (K46-M8527-
C0X). As a general guide, filters should be replaced
once every 3 months, although this depends on the
actual operating time.
5
Reattach the filter cap.
1. Fit the filter into the filter cap and insert it
into the ejector.
2. Turn the filter cap to the right until it locks
and clicks.
