5.2 Conveyor
5.2.1 Inspecting conveyor belt and cleaning guides and pulleys
As the conveyor belt wears away, slippages may occur that prevent securely conveying the boards.
It is therefore necessary to make periodic checks for wear of the conveyor belt.
Additionally, if belt wear debris accumulate on the light receiving surface of the conveyor sensor, troubles such
as incorrect board detection may occur. If belt wear debris accumulate in the belt guide or pulley periphery,
the belt may be fixed.
1
Change the conveyor width to a
convenient width for maintenance
work.
1. Press the [Width] button to display the
"Conveyor Width" screen.
2. Enter a width wide enough for a hex
wrench to be inserted (about 200 mm) in
the "Target Width" box and press the [OK]
button. The conveyor is changed to the
specified width.

Check the conveyor belt.
Check the transfer surface of the detached belt for worn-out or scuffing. If the belt worn-out amount or
scuffing is large, replace the conveyor belt referring to chapter 6, "4.1 Replacing the conveyor belt".
