Sensor Placed On Shutter Cylinder Maintenance Involved high project cost Breakdown cost is higher than project cost. Installation of Vibrator Production High noise level Noise level is within tolerance limit(<85db) Replaced belt conveyor with rack and pinion mechanism Maintenance Involved high project cost Implementing rack and pinion for permanent solution Need to replace good quantity of Index Pockets Maintenance Already procuring from OEM
