2.2 Parts recommended for periodic replacement
For parts listed in the table below, it may be predicted that the service life of the part is expired or the part
deteriorates even though no trouble is found through the visual check during the periodic inspection.
To maintain the performance of the machine at its optimal operating level, it is recommended to periodically
replace these parts.

Inspection and maintenance
2.3 Adjusting the conveyor transfer belt tension
The conveyor moves by belt drive to load boards ready for printing and to unload the finished boards. If the
conveyor transfer belt (hereafter "belt")is too loose, it may slip on the pulleys causing unstable board transfer. If
the belt is too tight, it may break or wear excessively.
If requiring the tension adjustment after replacing belt or inspected, adjust with the following procedures.
The tension of each belt on the fixed and movable rails should be adjusted evenly.
n
NOTE
The 2 types of belt below are set on the machine depending on the shipping time. The belt path and procedures of
applying tension also vary. Check the belt type to adjust it correctly.
n
Distinguishing between belts
Type A (KLV-M9127-00X)
•
The idler is not set to the downstream side (in front of exit).
•
The tension is adjusted by moving tensioner (pulley).
Type B (KLV-M9127-01X)
•
The idler is set to the downstream side (in front of exit).
•
The tension is adjusted by moving the tension adjustment plate. (Tensioner is not moved directly.)

Inspection and maintenance
2.3.1 Belt Type A
1
Change the conveyor width to a
convenient width for maintenance
work.
1. Press the [Width] button to display the
"Conveyor Width" screen.
2. In the "Target Width" box, enter a width
wide enough to insert hex wrench and
press [OK] button.
The conveyor is changed to the specified
width.

2
Press the emergency stop button
and open the upper door.
The machine must be in emergency stop to
ensure safety during work.
3
Remove the mask guide plates.
Remove 4 bolts with hex wrench (3 mm) and
detach mask guide plate. The mask guide
plate is on left and right.
53220-N1-10
4
Loosen the belt tension.
1. Mark the current tensioner position with
permanent marker before loosening belt.
2. Loosen tensioner mounting bolt with hex
wrenches (4 mm and 5 mm).
53221-N1-10
5
Tighten the tensioner temporarily.
If applying tension strongly, slide the bolt
mount position to black arrow's direction
shown at right. Sliding it to white arrow's
direction loosens the tension. After sliding
the bolt, mount the tensioner temporarily.
6
Measure the SPAN.
Measure the SPAN (distance between
pulleys) with scale shown at right.
