Have a Horizon Vac 100c Collator with Feed Sensor error in all 10 bins, ( first picture ). Base on the maintenance section of the operation manual of the collator there is a need to clean the Feed Sensor of the collator (second picture). Based on the manual, I have cleaned all 10 Feed Sensors. But the error in all 10 sensor would not go away. Also I have check and confirm all 12V pilot bulb 4mm are all good. Can anyone teach me on how to fix the collator. Thank you in advance all help is appreciated
